How would I alert the user if they selected more than one COP1000 and in another instance alert the user if they selected more than one COP 2830. Right now it notifies the user if they selected more than one class.
<script type="text/javascript" charset="utf-8">
var p = 0;
$(document).ready(function () {
$('input:checkbox').click(function () {
var COP1000 = $(this).attr('data');
if ($('input:checkbox:is_checked').attr()) {
p++;
}
if (p >= 2) {
alert('You can only select this class once');
return false;
}
});
});
<script>
Below are checkboxes with data being the name of the class
<input name="class[]" data="COP1000" value="<tr><td>COP1000 <td>8:00AM-9:00AM
</td><td>MWF </td><td>Sanford </td><td>3</td></tr>" type="checkbox" class="auto-
style88"/>
<input name="class[]" data="COP1000" value="<tr><td>COP1000 <td>11:30AM-12:00PM
</td><td>TTH </td><td>Altamonte </td><td>3</td></tr>" type="checkbox" class="auto-
style88" />
<input name="class[]" data="COP2830" value="<tr><td>COP2830 <td>11:00AM-12:00PM
</td><td>MWF </td><td>Sanford </td><td>3</td></tr>" type="checkbox" class="auto-
style88"/>
<<code><code></code></code>input name="class[]" data="COP2830" value="<tr><td>COP2830 <td>6:00PM-8:45PM
</td><td>T </td><td>Altamonte </td><td>3</td></tr>" type="checkbox" class="auto-
style88"/>

What's the question? The posted code looks like it should work (though I don't really know jQuery).
I'm not sure about putting markup in the value attribute of a checkbox, that looks dodgy, though not relevant to this issue.

|
|
|
<script type="text/javascript">
$(function(){
$("input:checkbox").click(function(){
var data=$(this).attr("data");
var count=$("input:checkbox:checked[data="+data+"]").length;
if(count>=2)
{
alert(data+" select more than one");
$(this).removeAttr("checked");
}
});
});
</script>

Hi,
I want to achive something and I don't know if it's possible.
I have an input of type "file" and I want to send the content of the selected file asynch with AJAX.
Is it possible?
|
|
|
|
|
Yes, it is possible in newer browsers. Take a look here[^] for the W3 details and here[^] for some examples.

Thank you.
It looks like I will have to use postback

There is strange problem i am facing.
I am using jquery in a MVC project.
Issues is that i am loading partialview in view using Ajax. Now jqeury [which is in view] events works fine in partialview when I use live. but then they don't work in view.
and if i use bind or event name "click" then it works in view and not in partialview.
I tried with on also but it given the same behavior as bind.
Any way to get same behavior in both partialview and view

I'm working on a project using Jscript on Microsoft IIS.
I already wrote a bunch of emulation functions to make the framework more compatible with modern ECMAscript implementations such as Mozilla´s.
One more thing I found missing in IIS/WSH/Jscript is the name property on a Function object. In a JavaScript running in a browser, you could write:
function MyFunc() { }
alert(MyFunc.name);
Currently I've built a Function.nameOf() helper function which extracts the function´s name from toSource()/toString() by the use of a simple RegEx.
Has anyone some idea how I could build a drop-in function so I gain full code compatibility and reusability between browser and server?
I thought of something like
Function.prototype.name={};
Function.prototype.name.valueOf=function() { }
so ".name" would appear like a property, and the valueOf()-function would be called implicitly as kind of a "get"-accessor.
But no matter how hard I try, i can´t figure out how I can determine from within the valueOf() method, which function was originally called and which´s name is to be extracted.
Any hints or solutions greatly appreciated!

I want to read data between html tag from website. How can I do it?
Please help me
thanks

are you interested in data on your own site (content from the same single page that also runs the script) or do you want to fetch from a remote site?
for the former, document.getElementById and element.innerHTML are your friends. for the latter, try asking Wikipedia and Google for AJAX and the XMLHttpRequest object.

I'm writing a simple piece of code to display a popup when somebody leaves my wordpress blog. It will simply ask if they wanted to register for my next open house before they leave the website.
Here's what I have...
<script language="JavaScript">
window.onbeforeunload = confirmExit;
function confirmExit()
{
return "Have you registered for my open house tour?";
}
</script>
That displays everytime a page is unloaded though... I want to simply check what the next page is and if it doesn't contain my domain then trigger the popup.
I found this code but it won't work because it shows the previous pages address when I need to see the next page to loads address.
var s = window.location.href;
var s = window.
return s;
Does anybody know how I can grab the next page that will be loaded from the browser?
Thanks!

Sorry, but I can only say I hope you will not get a solution ever, as my next page is none of your business!
Besides, what if the visitor closes his browser or his browser tab? When he does, there isn't a next page.
A better approach could be this: have each of your pages ask the question under some conditions, such as:
1. ask it only once
2. ask it only when the visitor has been on your site for more than 2 minutes
3. ask it only when the visitor has been on the same page for more than 20 seconds

You're probably right, it's probably not available to script for security/privacy reasons.
