Sorry Dave, but I can't just let that one slide....

I think you're getting a little confused by the default document (which is indeed usually called index or default, or even login!) - this is set in IIS / Web server to determine which file to send to the client when none is specified, so if your start page is http://blah.de.nobbs/default.aspx then entering http://blah.de.nobbs is sufficient - IIS then looks at what the default doc is and serves that back to the client.

Has nothing at all to do with the browser above and beyond making a request and recieving a response.

C# has already designed away most of the tedium of C++.

re-index array.

Hi
I have an array of objects that store information. call it guests. Lets say I have 5 guests added and I delete guest[2] then there will be 4 guests left. The array index does not auto correct in JavaScript. The values that are left are stored as:

guest[0]
guest[1]
guest[3]
guest[4]

Confused | :confused:

how can I correct this to:

guest[0]
guest[1]
guest[2]
guest[3]

I thought of using a temp array, copy it over to a correct index the copy the array back to the original, but this seems wrong somehow.

Ethius - I think you are looking for "splice()". A good, short, and to the point article was posted on StackOverflow: http://stackoverflow.com/questions/5237387/algorithm-to-re-index-an-array-of-objects-after-insertion-or-drag-n-drop-order

Using Splice you can insert and delete array elements with the added benefit of auto-reindexing.

How to separate an array of checkboxes into groups

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.

JavaScript

<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

HTML

<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-

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.

Yes, it is possible in newer browsers. Take a look here[^] for the W3 details and here[^] for some examples.

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

Function.name property missing on IIS/Jscript

captnmac9-Mar-12 7:12

9-Mar-12 7:12

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:

JavaScript

function MyFunc() { /*dosomething*/ }
alert(MyFunc.name);  //will popup "MyFunc"

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

JavaScript

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!
