Good Day All

in my page i have a hyperlink button in a gridview defined like this

JavaScript

<a href="#" onclick="<%#  String.Format("return showComment('{0}','{1}')", Replace(Eval("Field1").ToString(),Chr(13),"<BR>"), Replace(Eval("Field2").ToString(),Chr(13),"<BR>") ) %>">

                      <img src="../../Imgs/comment2.png" />
                      </a>

and the Function showComment is defined like this

JavaScript

function showComment(CommentPend,CommentCancel)
{
    $("#btnclose").unbind();
    $("#divPendComment").center();
    $("#divPendComment").fadeIn('slow');

    $("#txtcomment").val(CommentPend.toString().replace(/^[a-z0-9 ]$/i, ''));

    $("#txtcommentCancel").val(CommentCancel.toString().replace(/^[a-z0-9 ]$/i, ''));

    $("#btnclose").click(function (e)
     {

         $("#divPendComment").fadeOut('slow');
         e.preventDefault();

    });
    return false;
}

now as you can see i am trying to get rid of the special characters like the carriage returns but still i get a a javascript error when this link is clicked

I am not 100% sure what you are trying to achieve, but replace(/^[a-z0-9 ]$/i, '') is probably not what you intended: It says "If the whole field consists of a single letter, digit or space then set it to an empty string; if it is not just a single letter, digit or space, keep the whole lot as seen". My guess is that you want all non-letter/digit/space chars to be blanked out. Try replace(/[^a-z0-9 ]/ig, '').

How to select all the text in a Textbox in JQuery

Re: How to select all the text in a Textbox in JQuery

19-Oct-11 2:11

Good Day All

i have a Jquery code defined like this

JavaScript

// Let's add it to textarea this time
 $(".cnt").focus(function()
 {
     // Check for the change
     if(this.value == this.defaultValue){
         this.select();
     }
 });

and i am creating a textbox on fly and after creating it i bind data to it and after that i want to attach a focus event if there a value "0" on it

If cnt.Text = "0" Then
          cnt.CssClass = "cnt"
      End If

but still when i select a textbox that has "0" it does not select the whole content of the textbox. i went through a breakpoint and it goes through this line

cnt.CssClass = "cnt"

Thanks

First check if the HTML DOM element that corresponds to the textbox has its class attribute set to "cnt". You can do this with FF FireBug for instance or IE Developer Tools. Then change your javascript code like below to see if this.select() would ever be hit at all:

JavaScript

if(this.value == this.defaultValue){
    alert("Before this.select();"); // If you wont see this alert this.value does not equal this.defaultValue
                                    // Could it be that you wanted to check for unequal i.e. != ?
    this.select();
}

it sounds like what you are trying to do is change the class of the control and then expect events to be fired for any control that is bound to that class.

what you are running into is a late binding issue with jQuery. when you bound the focus event jQuery only did it for the controls that had that class at the time of the binding.

three approaches:

1 - bind the focus event for that class each time you add or remove it. personally not the best approach (IMO).

2 - bind the focus event to the control type and then in the focus event test to see if the control has that CSS class associated with it.

3 - use .live[^] which is supposed to work around the late binding issue. I personally have not had a chance to use it but it was designed to handle this very thing.

best of luck

Is it possible to change the size of entire website??

I am trying to do this to support users display resolution by changing size of my web page.

for e.g if resolution is 1280X1024, then width=100% and height =100%. This setting as it was made for this resolution.

if resolution is 1024X768, then width=90% and height=100%;

and other settings.
Is it possible to do it using javascript or any other language???
If yes then please post the code

Thank you for your help Smile | :)

Yes, you can change the dimensions of an HTML element using JavaScript. It would go something like this:

JavaScript

document.getElementById("someDiv").style.width = "700px";

Here is an example of how I have done it with an image: http://aspdotnetdev.com/DevPortfolio/FullscreenImage.aspx?ImageID=10

That's a little different than setting the size of a DIV, for example, because I used the width/height property on the image rather than the width/height property on the style of the image. Still, that should give you a good idea of how to resize webpage elements when the window size changes.

Now, if you are talking about changing the size of each element on a page, that would be much tricker. For that, just rely on the user to adjust their zoom level when viewing webpages.

really need to see the whole thing.

it could be various problems causing the problem. maybe another css dynamically updating the content or worse yet your code not running properly??

its extremely huge should I post everything including all the exisitng js?

Dennis E White19-Oct-11 3:42

19-Oct-11 3:42

maybe not.

what I would recommend instead then is breaking this up into its own example (but still full js and html) and working with it from there. I have found it best to isolate problems this way when the total solution has a lot of other "stuff" happening.

in debugging this my first assumption is that you javascript just isn't executing or isn't executing completely. after that I would assume that some sort of css rendering is interfering with what you are trying to do.

plus the other bonus in breaking it up into a small and complete solution is that you can post it back to a question forum when you have tried everything.

JavaScript

myHeight = window.screen.height; //this gives screen height
myWidth = window.screen.width; //this gives screen widht

If you want to find only the usable area (space that remains after taskbar etc) use "availHeight" and "availWidth"

So you can have various CSS classes for the various screen resolutions and by checking user's resolution you can change them on the fly!

CSS:

CSS

.class1024 {
color : "green";
}
.class800 {
color : "blue";
}

JavaScript:

JavaScript

if(myWidth == 1024) {
  elem.className='class1024'; 
}
else if (myWidth == 800) {
  elem.className='class800'; 
}

Hope this helps!
