I want to pass textfield with id value pat to the getautocomplete.action in Struts 2. Here I am using TINY.box to pop up the next page.
<s:textfield name="pat" id="pat"/>
<script type="text/javascript">
T$('tiny_patient').onkeypress = function(){
TINY.box.show('getautocomplete.action',1,0,0,1)
}
</script>
You need to append the id pat and its value to the url that you pass to the show function. For example
var url = 'getautocomplete.action?pat=' + $("#pat").val();
You can then use the variable url in your show function.
You also need to add the following in your action class. This also depends on the java type of pat. I am using String,
private String pat;
public String getPat()
{
return pat;
}
public void setPat(final String value)
{
this.pat = value;
}
Note
It is recommended to get your url using the following instead of hard-coding the extension
<s:url id="url_variable" namespace="/namespace_of_action" action="action_name" />
var url = '<s:property value="url_variable" />?pat=' + $("#pat").val();
If you are trying to populate the box based on previous box selection or any server side process you have to use ajax.
In your action class , write a getter-setter for variable named "pat" like this:
private string pat;
public getPat()
{
.........
}
public setPat(String pat)
{
this.pat=pat;
}
and change
TINY.box.show('getautocomplete.action',1,0,0,1)
to
TINY.box.show('getautocomplete.action?pat="xyz"',1,0,0,1)
Hope this will solve your problem unless you have an idea about ajax.
Try
<s:textfield name="pat" id="pat"/>
<script type="text/javascript">
document.getElementById("tiny_patient").onkeypress = function(e){
TINY.box.show("<s:url action='getautocomplete'/>"+"?pat="+document.getElementById("pat").value,1,0,0,1)
}
</script>

There are four query values which I want to put in google chart value1 to value4. The problem is passing values from java to html. Under below I posted relevant codes.
Those
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript">
google.charts.load("current", {packages:["corechart"]});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Task', 'Hours per Day'],
['value1', **3**],
['value2', **2**],
['value3', **2**],
['value4', **2**]
]);
var options = {
title: 'My Daily Activities',
pieHole: 0.4,
};
var chart = new google.visualization.PieChart(document.getElementById('donutchart'));
chart.draw(data, options);
}
</script>
And this is java class.
public ResponseEntity<Map<String,Object>> status() {
Map<String,Object> map = new HashMap<String,Object>();
long countByXmlSuccessResult = statusRepository.countByXmlSuccessResult();
long countByXmlErrorResult = statusRepository.countByXmlErrorResult();
long countByJsonSuccessResult = statusRepository.countByJsonSuccessResult();
long countByJsonErrorResult = statusRepository.countByJsonErrorResult();
map.put("xml success:", **countByXmlSuccessResult**);
map.put("xml error:", **countByXmlErrorResult**);
map.put("json success:", **countByJsonSuccessResult**);
map.put("json error:", **countByJsonErrorResult**);
return new ResponseEntity<Map<String,Object>>(map, HttpStatus.OK);
}
plus, html file path is under src/main/java folder and java file path is under src/main/resources folder.
You can expose that Java functionality as a service, and then make an ajax call to that service using jquery and finally grab the result and use it in your google chart code.
Ex:
Spring Boot:
#RestController
public class myHomeController{
...
#RequestMapping("/getValues")
public someDomainClass getMyValues(){
...
//someDomainClass is just a reg. pojo to store your values.
someDominClass class1 = new someDomainClass(value1, value2, value3
, value4);
return class1;
}
}
Your HTML file:
...
<script>
$.ajax({
url: "/getValues",
type: "GET",
success: function(result){
//result is a json object containing your values 1..4.
},
failure: functtion(err){...}
});
</script>
Best of luck :)
I`m just trying to pass values from my app to the webview using the examples from android developer page, throught javascript.
My webview is set with:
WebView navegador;
final JavaScriptInterface myJavaScriptInterface = new JavaScriptInterface(this);
navegador.getSettings().setJavaScriptEnabled(true);
navegador.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
navegador.addJavascriptInterface(myJavaScriptInterface, "navegador");
navegador.loadUrl(url);
Right under it i create the JavaScriptInterface class:
public class JavaScriptInterface {
Context mContext;
JavaScriptInterface(Context c) {
System.out.println("FaceWeb -> Navegador.java -> JavascriptInterface");
mContext = c;
}
public String getLogin(){
System.out.println("FaceWeb -> Navegador.java -> getLogin: "+b.getString("login"));
return b.getString("login");
}
public String getNome(){
System.out.println("FaceWeb -> Navegador.java -> getNome: "+ b.getString("nome"));
return b.getString("nome");
}
public Integer getId(){
System.out.println("FaceWeb -> Navegador.java -> getId: "+ b.getInt("id"));
return b.getInt("id");
}
}
And here my html:
<body>
<div id="teste">
Parado.
</div>
<input type="button" onclick="leitura()" value="Buscar Valores" />
<script type="text/javascript">
function leitura()
{
document.getElementById("teste").innerHTML = "Aguarde...";
var fonte = navegador.getLogin();
var id = navegador.getId();
var nome = navegador.getNome();
document.getElementById("teste").innerHTML = "Login: "+fonte + "<br>Nome: "+nome+"<br>ID: "+id;
}
</script>
</body>
In Eclipse log i can see that the functions getLogin, getId and getNome are called when the button is pressed on the webview, with right values, but my div "teste" remains with "Aguarde..." only and the button itself remains 'pressed'.
Any ideas please, reply. I really don`t know where to look anymore.
Try with public int getId() instead of Integer. Try with calling getLogin and getNome only. See if getId is the problemmaker. If you comment the last innerHtml out, does the button come up then?
I am new to Spring and web technology.
I have an table which contains a column with hyperlink. When I click on the hyperlink of a row, I need to display that rows data along with other details in a dialog. My controller method returns a ModelAndView which contains the data I need to show and the display page.
Problems:
How to show the dialog? and
How to pass the data to the dialog?
Table.jsp
<script type="text/javascript">
function showDialog(ref, date) {
$ajax({
type: "POST",
url: "/example/show.htm",
data: {
ref: ref,
date: date
}
success: function(data) {
},
error: function(data) {
}
});
}
</script>
Mapping
#RequestMapping(value = "show.htm", method=RequestMethod.POST)
public ModelAndView show(#RequestParam("ref") String ref, #RequestParam("date") String date,
HttpServletRequest request, HttpServletResponse response) {
ModelAndView modelAndView = new ModelAndView();
try {
SampleDTO SampleDTO = new SampleDTO();
sampleDTO.setDate(sdf.parse(date));
sampleDTO.setRef(ref);
SampleDTO billDto = // server call modelAndView.addObject("showBill", sampleDto);
modelAndView.setViewName("Dialog");
}
return modelAndView;
}
Your code is wrong, you are messing things, if you want to use jQuery and ajax calls then don't use ModelAndView in your Spring controller. Instead of that, use the following and return your bean or dto as a json using Jackson library from Java:
Include this jar in your lib project folder:
http://www.java2s.com/Code/JarDownload/jackson/jackson-all-1.9.9.jar.zip
Java code:
#RequestMapping(value = "businessBill.htm", method = RequestMethod.POST)
#ResponseBody
public String handleBusinessBillDetails(#RequestParam("reference") String billReference, #RequestParam("invoiceDate") String billDate,
HttpServletRequest request, HttpServletResponse response) {
String json = null;
try {
//1. Create 'jackson' object mapper
ObjectMapper objectMapper = new ObjectMapper();
BusinessBillDTO businessBillDTO = new BusinessBillDTO();
businessBillDTO.setBillDate(sdf.parse(billDate));
businessBillDTO.setBillReference(billReference);
BusinessBillDTO billDto = accountStatementBO.getBusinessBillDetails(businessBillDTO);
//2. Convert your 'bean' or 'dto' as 'json' string
json = objectMapper.writeValueAsString(billDto);
} catch (Exception ex) {
LOGGER.error(ex);
}
return json;
}
Then, in Table.jsp put the div used in Dialog.jsp as hidden, this will be your modal dialog in future (note that there are some changes in the span tags also):
<div id="BusinessBill" style="display:none;">
<h2>Bill Details</h2>
<em>Business Ltd</em>
<div class="row">
<span class="spanAsLabel">Account number</span>
<span id="dlg-account-number" class="spanAsLabel"></span>
</div>
<div class="row">
<span class="spanAsLabel">Bill date</span>
<span id="dlg-bill-date" class="spanAsLabel"></span>
</div>
</div>
Now fix your getBusinessBill(..) method like this:
You can also use $.ajax and maybe handle more states like onerror and others but this way is simpler (at least for me, you just need to evaluate if the returned data is null or not and let know the user - if null - that something happened at server side, maybe showing an alert with a generic message) - please read comments.
function getBusinessBill(billReference, billInvoiceDate) {
$.post("/AccountStatement/businessBill.htm", {
reference: billReference,
invoiceDate: billInvoiceDate
}, function (data) {
/* You can implement more validations for 'data', in my case I just used these 'if' conditionals but can vary. */
if(data != null) { //returned 'data' is not 'null'
/* parse 'data' as 'json' object
* will be good to console.log(data) and take a look. */
var obj = $.parseJSON(data);
if(obj != {}) { //check if 'data' is not an empty 'json' object once transformed
//set the 'data' in the dialog
$('#dlg-account-number').text(obj.accountNumber);
$('#dlg-bill-date').text(obj.billDate);
/* open modal dialog, you can simulate it this way (for this case)
* but the correct way is to use 'jquery-ui' dialog or any plugin you prefer.
* At this point you will see the hidden 'div' in a visible way with your 'data'.
*/
$('#BusinessBill').fadeIn();
} else {
//show 'generic' message
alert('No results found.');
}
} else {
//show 'generic' message
alert('An error occurred, try again.');
}
});
}
Finally, if everything is correct, you will see at the same page (Table.jsp) the modal dialog with your data, all made by an ajax call to avoid redirection pages like (Table.jsp to => Dialog.jsp).
I want to call java methods in javascript and Andrew Thompson suggested to use the deployJava.js library for this. I followed these instructions:
http://docs.oracle.com/javase/6/docs/technotes/guides/jweb/deployment_advice.html
Here is explained how to use the java class in javascript, but I would like to call the java methods from within the javascript. (This is because I want to import a .owl file in java en export the information in json-format to my code written in javascript.)
Does anybody know how to do this with the deployJava library?
This is my code to import the java file:
<noscript>A browser with JavaScript enabled is required for this page to operate properly.</noscript>
<h1>Sending Messages to Other Applets</h1>
<script>
function sendMsgToIncrementCounter() {
receiver.incrementCounter();
}
</script>
<p>Sender Applet</p>
<script>
var attributes = { id:'sender', code:'Sender.class', width:300, height:50} ;
var parameters = {} ;
deployJava.runApplet(attributes, parameters, '1.6');
</script>
<br/>
<br/>
<p>Receiver Applet</p>
<script>
var attributes = { id:'receiver', code:'../Receiver.class', width:300, height:50} ;
var parameters = {} ;
deployJava.runApplet(attributes, parameters, '1.6');
</script>
and this is are the sender and receiver java files:
import javax.swing.*;
public class Receiver extends JApplet {
private int ctr = 0;
private JLabel ctrLbl = null;
public void init() {
//Execute a job on the event-dispatching thread; creating this applet's GUI.
try {
SwingUtilities.invokeAndWait(new Runnable() {
public void run() {
ctrLbl = new JLabel("");
add(ctrLbl);
}
});
} catch (Exception e) {
System.err.println("Could not create applet's GUI");
}
}
public void incrementCounter() {
ctr++;
String text = " Current Value Of Counter: " + (new Integer(ctr)).toString();
ctrLbl.setText(text);
}
}
import javax.swing.*;
import java.awt.event.;
import netscape.javascript.;
public class Sender extends JApplet implements ActionListener {
public void init() {
//Execute a job on the event-dispatching thread; creating this applet's GUI.
try {
final ActionListener al = this;
SwingUtilities.invokeAndWait(new Runnable() {
public void run() {
JButton btn = new JButton("Click To Increment Counter");
add(btn);
btn.addActionListener(al);
}
});
} catch (Exception e) {
System.err.println("createGUI didn't complete successfully");
}
}
public void actionPerformed(ActionEvent e) {
try {
JSObject window = JSObject.getWindow(this);
window.eval("sendMsgToIncrementCounter()");
} catch (JSException jse) {
jse.printStackTrace();
}
}
}
I just copy-paste this from the example given on this site:
http://docs.oracle.com/javase/tutorial/deployment/applet/iac.html
This example works perfect in my browser, so the way it is done is correct, but I suspect that I don't import the javafiles correct, since this are the errors from je java-console:
load: class Sender.class not found.
java.lang.ClassNotFoundException: Sender.class

Combining your original method, with the new JS snippet, and part of the accepted answer on your last question (tweaked), gives..
<html>
<head>
<script>
// dangerous to have a 0x0 applet! Some security plug-ins regard it
// as suspicious & automatically remove the element. Better to set it
// not visible using styles
var attributes = {
codebase:'../sesame',
code:'applet_test',
width:10,
height:10
};
var parameters = {fontSize:16} ;
var version = '1.6' ;
deployJava.runApplet(attributes, parameters, version);
function test() {
var app = document.applet_test;
alert("Screen Dimension\r\n width:" + app.getScreenWidth()
+ " height:" + app.getScreenHeight());
}
</script>
<body>
<FORM>
<INPUT
type="button"
value="call JAVA"
onClick = "test()">
</FORM>
<script>
deployJava.runApplet(attributes, parameters, version);
</script>
</body>
</html>
But I just wrote that up off the top of my head. Don't trust me, trust a validation service. ;)
I would advise setting up a simple webservice that your javascript code can use. It doesn't need to be very involved, personally I'd use a simple REST layout with JAX-RS (jersey is really nice to work with), especially if you want something simple with JSON support built-in (with the right plugin).
Trying to actually communicate with the applet on the page might be possible, but very browser dependent and IMHO not worth the hassle. If you're working on the web, might as well use a web service.
There was a problem with the directory of the .class files given in the attributes. Here is the correct code:
<p>Sender Applet</p>
<script>
var attributes = { id:'sender', code:'sesame/Sender.class', archive:'sesame/applet_SenderReceiver.jar', width:300, height:50} ;
var parameters = {} ;
deployJava.runApplet(attributes, parameters, '1.6');
</script>
<br/>
<br/>
<p>Receiver Applet</p>
<script>
var attributes = { id:'receiver', code:'sesame/Receiver.class', archive:'sesame/applet_SenderReceiver.jar', width:300, height:50} ;
var parameters = {} ;
deployJava.runApplet(attributes, parameters, '1.6');
</script>
I have defined in my head tag a function <script> functionX(a,b,c) ....</script>
which calls some third party js. The actual function is this:
<script>
function fbc(d, s, id)
{ var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) {return;}
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/all.js#xfbml=1";
fjs.parentNode.insertBefore(js, fjs);
}
</script>
and later on I want to call that function. I'm calling it using and HTML widget in the following way:
HTML html = new HTML();
setHTML(
"<script>"+
" fbcomment(document, 'script', 'facebook-jssdk'); "+
"</script> "+
"<fb:comments width=\"600\" num_posts=\"2\" href=\"http://www.woojah.com\"></fb:comments>");
However, it is not executing properly. Any advice would be very useful.
It is more idiomatic to call external functions using JSNI:
native void facebookComment(Document d, String s, String id) /*-{
fbc(d, s, id);
}-*/;
void myFunction() {
facebookComment(Document.get(), "script", "facebook-jssdk");
}
