Validate textboxes
 

useing this code I avoid to paste invalid chracters to textboxes.

function PasteAlphaNumeric(objEvent)
{
var strPasteData = window.clipboardData.getData("Text");
var objInput = objEvent.srcElement;
if (strPasteData.search("[^A-Za-z0-9]")!=-1) {
alert("The character you attempted to paste is not allowed for this field.");
objInput.focus();
return false;
}
}

I want to allow to paste white space characters (\s) and[A-Za-z0-9] to the textbox, how can I do this.

You could use an expression modifier, to add the /s to your character array. I haven't tested it, and it's late, but try:

function PasteAlphaNumeric(objEvent)

{

  var strPasteData = window.clipboardData.getData("Text");

  var objInput = objEvent.srcElement;

  if (strPasteData.search("[^A-Za-z0-9]+/s")!=-1)

  {

    alert("The character you attempted to paste is not allowed for this field.");

    objInput.focus();

    return false;

  }

}

thanks for your advice, but it was not working, any other ideas?

Sorry. Include the "\s" special character within your character class. You'll need to escape the blackslash WITH a backslash. For example this works:

function testRegEx(x)

{



  var regex = new RegExp("[^A-Za-z0-9\\s]");



  if (x.value.search(regex) != -1)

  {

    alert("Invalid Entry.");

  }

}
