<body>
<input type="button" id="id100" onclick="changeLink()" value="Change link">

</html>
Thanks!
Replace
document.getElementById("id200").value = someOtherName;
by
window.opener.document.getElementById("id200").value = someOtherName;
previous answer +1
but it will work only on the same domain or if the server sends special header
you can use cookies or local storage
save in it state on the second page and get it on the first page
also you can use php script and get/save the state from/to there
you had missed the third parameter at xhr.open
and never use sincronious requests

You are missing the quotes for the src plus you should break up the string and add the variable to prevent it reading p as text.
Update the JS to the following:
<script type="text/javascript">
function setImg(p)
{
document.getElementById('img').innerHTML ="<img src='" + p + "' width='100' height='105'>";
}
</script>
Plus in the HTML you need to be careful with quotes:
load image

load image
<div id="img">

Well your were closing html attribute accidentally, you should use ' single-quotes instead.
Small mistake of quotes
change
load image
to
load image
My code works inside an html but not from an external .js file.
In my external .js, I have a function like .animate() and hide() etc. working fine but
just for functions like .text() or .html() it is not working in the external file.
I even deleted all my code and just kept this script, still it didn't work, but when I copy pasted into my html it worked.

Try this in your JS
$(function() {
$("button").click(function(){
$("#demo").html("text");
});
});
your html code is fully messed up!! update your code with the below
HTML
<!DOCTYPE html>
<html>
<head>
<title>Test Page</title>

<body>
<div id="demo"> --- </div>
<button>click me</button>

$(function() {

});
});

I hope every one familiar with gmail chat where you can pop out your chat window in to new window with its content and if you press the pop-in that new window will be placed in that previous position
I did some work around for that and the following is my problem
I am able to open the content in new window with out its content for example if I have typed in the text box in child.html which is inside the iframe is not showing when on the popout.

var s=document.getElementById('page').innerHTML;
console.log(s);
winObj.document.write(s);

You need a semicolon.
function openerChange()
{
window.opener.document.getElementById('text1').value="Value changed..";
}
I would like to create multiple strings within this same function and make this code more useable across website.
My JS code look like this:
function() {$(".tool-tip-wrapper").click(function () {
$(".tool-tip",this).html("<img src='/images/ui-elements-sprite.png' class='top-arrow'><p>This is string one.</p><div class='close'></div>").toggle('fast');
});
My html code look like this:
<div class="tool-tip-wrapper"> click me
<div class="tool-tip"></div>
</div>
Below markup will solve the issue.

I am new to JavaScript and here is a problem when I trying out prototype.
I want to update sample.jsp with Ajax.updater after the it is loaded, but it doesn't work. Here the source of smaple.jsp.
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
<script src="prototype.js"></script>
<script>
function f1(){
var ajax = new Ajax.updater(
{success: 'state'},'part.html'
,{method:'get'});
}
document.observe('dom:loaded', function() {
f1();
});
</script>
</head>
<body>
state:
<div id="state"></div>
<br>
</body>
</html>
Could anyone tell me what's wrong with my code?
try "Ajax.Updater" (capital U) for starters
also I recommend that you try working with firefox and the firebug plugin, it's a great way to debug your javascript
I have tried another one and it works
