When I use form action URL with 'www' prefix, by pressing the submit button (or enter key) the form does not work: submits but won't send any variables. It does work, however, with JS submit by clicking the magnifier, even though JS code does not affect the URL (at least as far as I know).
When I remove 'www' it works both ways. Any idea what the reason is behind this?

I made a gray div above the form to display POST variables.
Here's my code:

Function: Enter a phone number (ex: 555-555-5555) into a text field. The text field prints the number out flat (hidden by CSS). Then Javascript picks up that number by ID and splits it apart by the hyphens and injects the array split up into a FoneFinder URL search string to display the results from that site in a pop-up window.
Problem: The pop-up is working fine, however when I click on the link to spawn the link it opens in the main page as well as the pop-up. The main page should not change.
The pop-up code works fine on other pages and doesnt overwrite the main page. It has to be how the javascript is injecting the html link into the page that is messing it up, but I cant figure out why.
Any help or insights would be appreciated.

what you need to add is the following:
$('#target_num_search').on('click', 'a', function (event) {
event.preventDefault();
var url = $(this).attr('href');
NewWindow(url,'FoneFinderLookup','740','680','yes');
})
This way you can remove the onclick attribute and move the function call to js. See the working jsfiddle
you should return false for prevents default action to go link 'href' when onlick event.
(please notes , - comma operator to whatever Function returns... It's just hack. don't use.)

I need to load an aspx page that returns a string of text using jsonp since it is a cross domain call. The target page will be loaded inside a div tag and displayed as a modal window on the source page.
I am using a test form to pass 3 parameters that the target page expects, a submit button, very simple.
When I submit the page, I get an error message: Uncaught SyntaxError: Unexpected token <
When I click on the error I see the error points to this line:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
This is the first time I am working with json/ jsonp, and I am not sure how to fix this error. Is it possible to get some help to figure this out?

The error is clearly caused by your AJAX call return HTML instead of JSON.
In the success handler you have $("#dialog").html(r.d);. Here you try to parse the output of the call (r) to an object (r.d forces this), which fails for obvious reasons.
You should return JSON from your AJAX method, possibly using an HTTP handler or WebAPI.

How to hide div tag when $message value not come.
i want to hide my div tag. in jsp page. when user click on home page.
i tried here javascript code but did not get any answer to how to user jsp element in javascript.
or any code which usefull to hide div tag in my case do suggest. thank u....
Try this
<c:if test="${empty message}">
</c:if>
<c:if test="${not empty message}">
<div id="tempDiv">
<h1>Message : ${message}</h1>
<h1>Author : ${author}</h1>
</div>
</c:if>
You need to check if the variable is empty and depending on that print out on the html page...hope it works
or another way
<c:choose>
<c:when test="${empty message}">
</c:when>
<c:otherwise>
<div id="tempDiv">
<h1>Message : ${message}</h1>
<h1>Author : ${author}</h1>
</div>
</c:otherwise>
</c:choose>
Is there a command line tool or online service that can convert javascript unicode notation code to utf-8?
E.g. I got this json code, but it is hard to edit in common text editor.
{"name":"leon zhang","city":"\u4e0a\u6d77"}
I want to convert it to:
{"name":"leon zhang","city":"上海"}
You use the below javascript function to convert unicode to utf-8
function encode_utf8( s ){
return unescape( encodeURIComponent( s ) );
}( '\u4e0a\u6d77' )
You can also try it out in firebug console. It works.

var re = /(%)+/g;
var result = escape(c);
document.all.content.value = result.replace(re, "\\");
document.all.content.focus();
document.all.content.select();
}
function clearContent(){
document.all.content.value = "";
document.all.content.focus();
}
</script>
<body>
<h3 align="center">UTF-8 To Unicode</h3>
<table width="600" border="1" cellspacing="0" cellpadding="0" align="center" style="text-align:center;">

<tr>

This is a sample of convert utf-8 to unicode, do it in turn.
