How to call a JavaScript function from java code android native

How to call a JavaScript function from java code android native - java

I need to load a HTML file which internally has some AJAX service calls.
I need to call a function in that HTML file from Java code.
I can see the data loading in web but not in Emulator.
My HTML file is below

<div id="chart2" style="height: 400px; width: 720px;">
</div>
In that code I need to call getData() passing 3 parameters from Java code.
My Java code is below:
webView.addJavascriptInterface(new JavaScriptInterface(this), "Android");
String loc = "file:///android_asset/candlechart/candlebar.html";
webView.getSettings().setJavaScriptEnabled(true);
webView.clearView();
// myWebView.measure(100, 100);
webView.getSettings().setUseWideViewPort(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.loadUrl(loc);
webView.loadUrl("javascript:getData('1020','M','bar')");
webView.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String loc) {
}
});

You are calling your second loadUrl() way too soon. loadUrl() is asynchronous. You need to wait until your page is loaded. Call webView.loadUrl("javascript:getData('1020','M','bar')"); in the OnPageFinished method.

Spring Boot + Swagger + custom swagger-ui.html

I've got problems migrating a war application to a spring boot jar application.
I'm using spring boot 1.4.1 and swagger 2.6.0.
To customize swagger ui in a war you have to put a custom swagger-ui.html to /webapp directory. In spring boot it is not recommend to use the webapp directory because it does not work in a bundled jar. But putting a custom swagger-ui.html to /resources/static will be ignored by swagger.
Is there any simple solution (instead of adding the whole swagger distribution to my application)?
My custom swagger-ui.html looks like

I have found this simple way to customize Swagger into a Spring Boot application with just two files copied from original springfox-swagger-ui
First of all i have disabled #Configuration from SwaggerConfig.java:
//#Configuration <-- Attention, disable Configuration
#EnableSwagger2
public class SwaggerConfig {
#Bean
public Docket productApi() {
return new Docket(DocumentationType.SWAGGER_2)
.ignoredParameterTypes(Pageable.class)
.select().apis(RequestHandlerSelectors.any())
.paths(regex("/v1/.*"))
.build();
}
}
Then I have extended a WebMvcConfigurerAdapter:
#Configuration
#Import(SwaggerConfig.class)
public class MvcConfig extends WebMvcConfigurerAdapter {
#Override
public void addResourceHandlers(final ResourceHandlerRegistry registry) {
registry.addResourceHandler("/doc/v1/**").addResourceLocations("classpath:/doc/v1/");
registry.addResourceHandler("/doc/v1/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
}
}
Then I have just copied original file swagger-ui.html into src/main/resources/doc/v1/api.html with just a simple modification.
I have substituted this line:
<script src='webjars/springfox-swagger-ui/springfox.js' type='text/javascript'></script>
with this line:
<script src='js/swagger.js' type='text/javascript'></script>
This is my api.html

After that i have copied original springfox.js into src/main/resources/doc/v1/js/springfox.js where i have changed these lines:
"baseUrl": function() {
var urlMatches = /(.*)\/swagger-ui.html.*/.exec(window.location.href);
return urlMatches[1];
},
with these lines:
"baseUrl": function() {
return window.location.origin;
},
This is my complete springfox.js
$(function() {
var springfox = {
"baseUrl": function() {
return window.location.origin;
},
"securityConfig": function(cb) {
$.getJSON(this.baseUrl() + "/swagger-resources/configuration/security", function(data) {
cb(data);
});
},
"uiConfig": function(cb) {
$.getJSON(this.baseUrl() + "/swagger-resources/configuration/ui", function(data) {
cb(data);
});
}
};
window.springfox = springfox;
window.oAuthRedirectUrl = springfox.baseUrl() + '/webjars/springfox-swagger-ui/o2c.html';
window.springfox.uiConfig(function(data) {
window.swaggerUi = new SwaggerUi({
dom_id: "swagger-ui-container",
validatorUrl: data.validatorUrl,
supportedSubmitMethods: data.supportedSubmitMethods || ['get', 'post', 'put', 'delete', 'patch'],
docExpansion: data.docExpansion || 'none',
jsonEditor: JSON.parse(data.jsonEditor) || false,
apisSorter: data.apisSorter || 'alpha',
defaultModelRendering: data.defaultModelRendering || 'schema',
showRequestHeaders: data.showRequestHeaders || true,
timeout: data.requestTimeout,
onComplete: function(swaggerApi, swaggerUi) {
initializeSpringfox();
if (window.SwaggerTranslator) {
window.SwaggerTranslator.translate();
}
$('pre code').each(function(i, e) {
hljs.highlightBlock(e)
});
},
onFailure: function(data) {
log("Unable to Load SwaggerUI");
},
});
initializeBaseUrl();
function addApiKeyAuthorization(security) {
var apiKeyVehicle = security.apiKeyVehicle || 'query';
var apiKeyName = security.apiKeyName || 'api_key';
var apiKey = security.apiKey || '';
if (apiKey && apiKey.trim() != "") {
var apiKeyAuth = new SwaggerClient.ApiKeyAuthorization(apiKeyName, apiKey, apiKeyVehicle);
window.swaggerUi.api.clientAuthorizations.add(apiKeyName, apiKeyAuth);
log("added key " + apiKey);
}
}
function log() {
if ('console' in window) {
console.log.apply(console, arguments);
}
}
function oAuthIsDefined(security) {
return security.clientId
&& security.clientSecret
&& security.appName
&& security.realm;
}
function initializeSpringfox() {
var security = {};
window.springfox.securityConfig(function(data) {
security = data;
addApiKeyAuthorization(security);
if (typeof initOAuth == "function" && oAuthIsDefined(security)) {
initOAuth(security);
}
});
}
});
$('#select_baseUrl').change(function() {
window.swaggerUi.headerView.trigger('update-swagger-ui', {
url: $('#select_baseUrl').val()
});
});
function maybePrefix(location, withRelativePath) {
var pat = /^https?:\/\//i;
if (pat.test(location)) {
return location;
}
return withRelativePath + location;
}
function initializeBaseUrl() {
var relativeLocation = springfox.baseUrl();
$('#input_baseUrl').hide();
$.getJSON(relativeLocation + "/swagger-resources", function(data) {
var $urlDropdown = $('#select_baseUrl');
$urlDropdown.empty();
$.each(data, function(i, resource) {
var option = $('<option></option>')
.attr("value", maybePrefix(resource.location, relativeLocation))
.text(resource.name + " (" + resource.location + ")");
$urlDropdown.append(option);
});
$urlDropdown.change();
});
}
});
This is my folder structure
Now you have just to run application and go to http://localhost:8080/doc/v1/api.html

Solution if you are using maven:
You should copy swagger-ui.html into src/main/webapp
Make your editions or replace screen.css by your theme.css
Than add these code into your pom.xml:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<webResources>
<resource>
<directory>${basedir}/src/main/webapp</directory>
<filtering>true</filtering>
<includes>
<include>*.css</include>
<include>*.html</include>
</includes>
</resource>
</webResources>
</configuration>
</plugin>
</plugins>
</build>

How to create editable combobox with database?

I am new to java and want to create an editable combobox in which when user types in it the results come from database.
Like if I type "e" in combobox then all the name starting with "e" should come from database.
Please give a simple example.

You can use jQuery plugins, following example is for php just replace the php parts with java code, or have a look at this.
With JSON
$(document).ready(function() {
$(function() {
$("#search").autocomplete({
source : function(request, response) {
$.ajax({
url : "SearchController",
type : "GET",
data : {
term : request.term
},
dataType : "json",
success : function(data) {
response(data);
}
});
}
});
});
});
With DB
<!doctype html>

});

dynamic fields using jquery in jtable

here the fields are hard coded but i want to get the fields dynamically for my task,like i will have a list in this jsp which contains field names eg: list=[id,name,salary,doj] this list may change for new requests. Can i have some ideas to do this
fields: {
PersonId: {
key: true,
create: false,
edit: false,
list: false
},
Name: {
title: 'Author Name',
width: '40%'
},
Age: {
title: 'Age',
width: '20%'
},
Watch: {
title: 'Watch',
width: '20%',
display: function (data) {
return '';
},
RecordDate: {
title: 'Record date',
width: '30%',
type: 'date',
create: false,
edit: false
}
}
});

You can build Javascript code dynamically on server side.
For client side, you can also create fields dynamically.
var fields = {
PersonId: { //I assume that this field is standard
key: true,
list: false
}
};
if(someCondition) {
fields['Name'] = {
title: 'Author Name',
width: '40%'
};
}
//Add other dynamic fields
$('#PersonTableContainer').jtable({
title: 'Table of people',
actions: {
listAction: '/GettingStarted/PersonList',
createAction: '/GettingStarted/CreatePerson',
updateAction: '/GettingStarted/UpdatePerson',
deleteAction: '/GettingStarted/DeletePerson'
},
fields: fields
});
In your condition, you can add fields from a list surely.

In my code, I used window.print() method, but when I print the page, chart disappears from the webpage and rest of the content is printing.
Please help me.

The method window print() will simply open the print dialog. How the page is formatted for print depends on how the browser formats webpages and the print stylesheet if present.
Assuming the chart is some kind of image (or canvas), it might be that the browser choses to strip images when printing. Especially if the image is added using css background-image: url(...) because it assumes a background image (like background-color) is just for decoration and would waste ink if printed.
A plain img tag should print though in most cases unless some css is removing it for print...

when above code executes, it shows the output, but it does not show the datepicker in the sdate column. Please let me khow if I am wrong somewhere in the code!
I think i have done a silly mistake, but not able to find it!

I would recommend you full rewrite your code. The most important problems:
you need use <!DOCTYPE html ...>. It's very important because HTML without <!DOCTYPE> statement switch on quirks mode which is not supported by jQuery UI and jqGrid.
you should use data: mydata3 instead of filling grid with addRowData in the loop
you need call datepicker once (currently you call datepicker in both dataInit and oneditfunc parameter of editRow - pickdates)
you need include every CSS and JavaScript file once. For example "js/jquery-ui-1.9.2.custom.css" should be enough. It should contain all CSS of jQuery UI (inclusive ui.datepicker.css). So you should remove lines with "css/ui.datepicker.css", "css/jquery-ui.css", css/jquery.ui.theme.css and "css/jquery.ui.datepicker.css"
you should use jQuery.ready instead of usage onload.
you should define all variables inside of some function (like inside of $(function () {/*here*/})). In the way you will have no global variables.
you should be careful with encoding of special characters (like <) in case of usage inline code in HTML page. Try to validate the page on http://validator.w3.org/ for example and you will find the errors which I mean.
I would strictly recommend you to use gridview: true to improve performance and use autoencode: true to be sure that jqGrid could display any text in the grid.
UPDATED: The demo shows an example how the code could be modified. Below if the full HTML code. I used non-minimized version of all JavaScript files for better debugging. The productive code should use minimized version of the corresponding files:

I don't see any jquery-ui.js script included in your code.
For example:
<script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"></script>
if you don't include that script you don't have jQuery-UI loaded and you can't use the datepicker widget.

Maybe try this:
function pickdates(id){
jQuery("#rowed6 .hasDatepicker").datepicker('destroy');
jQuery("#"+id+"_sdate","#rowed6").datepicker({dateFormat:"yy-mm-dd"});
}
Or by autotriggering click() handler adding click() at end:
jQuery("#"+id+"_sdate","#rowed6").datepicker({dateFormat:"yy-mm-dd"}).click();
