I am very new to ASP.Net.
I was trying to put some controls on the screen but i m unable to move it using mouse. By key board(using space bar) it moves.
What might be the reason?

How are you trying to move controls ? Do you mean in the design view ?

ASP.NET, and indeed, HTML is based on a top down document model. You don't position controls the way you would in a winforms app, you simply lay them out top to bottom, although you can use CSS To position controls absolutely, it should not be the rule that you define a bunch of controls and then position them all absolutely in that manner.

if you're using the design view, forget it. Your best bet is to run the web app, play with the script and keep refreshing the page. The auto generated HTML really sucks.

Yes, that's the only way I've ever learned anything, and I'd say it's the best.

Removing a Node w/Javascript

I want to remove a TABLE node by using the following javascript.

e = document.getElementById( "tableId" );

document.body.removeChild( e );

However, it doesn't remove the node. It says "Invalid argument" in the second line of code.

Can someone point out why it won't let me do that?

It might not be a child of the body...?
Generally, i'd write e.parentNode.removeChild(e) to detach the element e from its parent, unless i was absolutely certain that the node i was removing was a direct child of the body. Heck, i'd probably do it then too, just 'cause it's obvious what i'm doing. Also, it reminds me of that cartoon where the hapless character saws off the branch he's sitting on...

You're right, it's actually a direct child of a DIV tag.

But the DIV element doesn't support removeChild(), so how would I remove the table tag?

Yes, if you're only auditing actions on the database, triggers make a lot of sense

[discussion] JS 1.7 and 1.8 in Firefox3

I downloaded the firefox 3 installer ( firefox-3.0b2pre.en-US.win32.installer.exe) from this link. (It shows as Minefield that I have no idea. maybe codename)

And I'm trying to do some javascript stuffs with FF3. and I come out a few questions...

1. Generators

function fib() {<br />
  var i = 0, j = 1;<br />
  while (true) {<br />
    yield i;<br />
    var t = i;<br />
    i = j;<br />
    j += t;<br />
  }<br />
}<br />
<br />
var g = fib();<br />
for (var i = 0; i < 10; i++) {<br />
  document.write(g.next() + "<br>\n");<br />
}<br />

it seems interesting. It helps us to write the shorter code.. but I don't understand why we need to do this.. I have googled about this and I can't think of any useful scenario where this code fits in.

Does anyone know the case where we can't live without this feature??

2. Iterator

This one is awesome.. vote 5. Smile | :)

3. Array comprehensions

var evens = [i for (i in range(0, 21)) if (i % 2 == 0)];

No. It doesn't work.. Has anyone tried this thing with Firefox 3? Actually, what the doc said is that it should work in both Firefox2 and Firefox3.

4.let

This one is also another awesome thing.. The example below (from Mozilla doc) shows the power and usefulness of "let" keyword

var list = document.getElementById("list");<br />
for (var i = 1; i <= 5; i++)<br />
{<br />
  var item = document.createElement("LI");<br />
  item.appendChild(document.createTextNode("Item " + i));<br />
  let j = i;<br />
  item.onclick = function (ev) {<br />
    alert("Item " + j + " is clicked.");<br />
  };<br />
  list.appendChild(item);<br />
}<br />

5. Destructuring assignment

<br />
var a = 1;<br />
var b = 3;<br />
<br />
[a, b] = [b, a];<br />

This is also useful. But it doesn't work with Firefox2 (the doc said that it should work. ) anyway, it works fine with Firefox3.

6. Expression closures

function(x) x * x

I have no idea about how to use this in my project.. Can anyone give me the example about how to use this closures and why we need this?? Thanks.

I haven't tried with expression generator, array reduce and etc.. I'm not so sure why "Array comprehensions" doesn't work in FF3. and also, I would like to get the explanation about Generators and Expression closures with examples.

Thanks in advance..

P.S: I should have posted this post in lounge. :P (just kidding)

Thanks and Regards,

How to read file from local disk in javascript?

I don't know of a situation where it's indispensable, but it can make life easier. Heck, that goes for all of these. Smile | :)

It's a common pattern: there's a generated set that you're gonna iterate through, but there are a large enough number of elements... or calculating each element costs enough... that you'd rather do so on an as-needed basis. For instance: a Google Reader-style "virtual list" where additional list elements are loaded only when the user has scrolled past the already-loaded elements.

Michael Sync wrote:

Works for me - in fact, i use them in CPhog. You do need to define the range() function in order to make the example work.

These are just shorthand for a function that returns a value.

One more thing I forget to tell is I am using the following code to read the file:
function ReadIt()
{
var filename = 'client side file-name';
if (confirm('Do you want to see what we put on your computer?'))
{
var fso, a, ForReading;
ForReading = 1;
fso = new ActiveXObject('Scripting.FileSystemObject');
file = fso.OpenTextFile(filename, ForReading, false);
while (!file.AtEndOfStream)
name += file.ReadLine( ) + "\n";
alert(name);
}
}

And when i run it through server I am getting following error:
"Automations server cannot create object"..
Can any one Please suggest?

Thanks,

RK..
