I am new to ajax and jquery and trying to place an ajax call in my code. But below are the error messages I get when placing alerts:
jqxhr.status = 404
thrown error = Not Found
jqxhr.statusText = Not Found
request = undefined
error = undefined
What I want to do:
Open a modal dialog with just a Fancy text box (Tinymce) on click of an "Edit gif". After the contents are edited in the textbox, and the "Save" button in the modal dialog is clicked, initiate an ajax call to save the contents in the Database.
What is happening:
The modal dialog opens correctly, I am able to see that the "data" part for the ajax call is populated correctly (placed alerts to confirm). I believe the url is also correct. If I type the url in a browser, the control does go to my servlet as per web.xml (Sysout in Servlet gets printed). But somehow, the ajax call never goes through to the server after click of "Save" button. Will be really great if one of you can help me out here, will greatly appreciate it. My JSP (copied what I feel is relevant alone):

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

i have written a small code which inclued 2 jsp pages and
1) test2.jsp --> i have made a dropdown in this page
2) test3.jsp --> displays a welcome message when the person selects an option from the dropdown ,
he will migrate to this page without refreshing test2.jsp
for this i have used ajax jquery
when i click on the submit button nothing happens , please help me with this
i have also put the org.json.jar file in the libraries
test2.jsp code
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="//malsup.github.com/jquery.form.js"></script>
<script>
function check()
{
$.ajax({
url: "test3.jsp",
type: "GET",
success: function() {
alert("succes");
},
error: function() {
alert( "Sorry, there was a problem!" );
}
});
}
</script>
</head>
<body>
<h1>Hello World!</h1>
<br>
<form method="post" action="test2.jsp">
<select name="city">
<option value="dropdown">select city</option>
<option value="jal">Jalandhar</option>
<option value="ggn">Gurgaon</option>
<option value="noida">Noida</option>
<option value="amrtsr">Amritsar</option>
<option value="bombay">Bombay</option>
</select>
<input type="submit" value="Submit" onclick="check()">
</form>
test3.jsp code
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<h1>welcome</h1>
</body>
</html>
The function should return false to prevent form submittion
<script>
function check() {
$.ajax({
url: "test3.jsp",
type: "GET",
success: function() {
alert("succes");
},
error: function() {
alert( "Sorry, there was a problem!" );
}
});
return false;
}
</script>
It should be
<input type="button" value="Submit" onclick="check()">
instead of
<input type="submit" value="Submit" onclick="check()">
because submit input type call form's action that is test2.jsp.
call your javascript function on change event of drop down
onchange="check()"
and navigate through firebug and check your consol it will show you your whole ajax request

There is a plugin on ghithub developed by javatechig here but only work with old cordova/phonegap version. This fork https://github.com/aharris88/phonegap-sms-plugin works with recent version of cordova and is updated frequently. Read the "readme.md" for example and more informations.
This Android Phonegap plugin allows you to easily send SMS in android using both native SMS Manager or by invoking the default android SMS app

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...
There is a simple web page which sends request, handles & manipulated by a servlet class and send back the response text.while i want ajax type handleing the request at client side that is why i am giving the response target to a invsible iframe. *but i want to print success on the page after iframe gets the response *
<html> <body>
<form action="test" method="post" target="IFrame"> /*response target is iframe*/
<input type="text" name="logic" />
<input type="submit" value="Submit" />
</form>
<iframe name="IFrame" style="width:0; height:0"> </iframe>
</body> </html>
i think this can be done using javascript or jquery, please guid me if you have any idea.
In the page which loads in the iframe, you will need to invoke a parent function.
<!-- This is the Parent. Call it JSTest1.html -->
<html>
<head>
</head>
<body>
<script type="text/javascript">
function parentAlert() {
alert('hey there from the parent');
}
</script>
I'm the parent
<iframe src="/JSTest2.html"></iframe>
</body>
<!-- this is the iframe html loaded. Call it JSTest2.html-->
<html>
<head>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
</head>
<body>
<script type="text/javascript">
$(document).ready( function() {
window.parent.parentAlert();
});
</script>
In the Iframe.
</body>
To send a message from Iframe to Parent window page:
<script type="text/javascript">
$(document).ready( function() {
//Message part is two parts Event name and Data you want to send
// Example message = "my_action,my_data"
message = "my_action,my_data"
parent.postMessage(message, "*");
});
</script>
At the parent window you can do the following to listen to this message and capture it:
var eventMethod = window.addEventListener ? "addEventListener" : "attachEvent";
var eventer = window[eventMethod];
var messageEvent = eventMethod == "attachEvent" ? "onmessage" : "message";
eventer(messageEvent,function(e) {
// Youe message which you send is captured here in e.data will split it on ',' to get the event and the data
message = e.data.split(',')[0]
value = e.data.split(',')[1]
if ( message === "my_action" ) {
myParentFunction(value)
}
},false);
