WebtextEdit execute Javascript function

Question

Hi, I need to execute an entire javascript function.

Found what i was doing wrong:

var edit = igedit_getById("FG2100RefNo");
var editText = edit.getText();
alert(!isNaN(editText));

But this only checks & displays a message box.

I need to execute the below javascript:

<SCRIPT language=Javascript>
  <!--
  function isNumberKey(evt)
  {
     var charCode = (evt.which) ? evt.which : event.keyCode
     if (charCode > 31 && (charCode < 48 || charCode > 57))
        return false;

     return true;
  }
  //-->

onkeypress="return isNumberKey(event)"

How do i do this with the webtextedit:

var edit = igedit_getById("FG2100RefNo");
var editText = edit.getText();
function isNumberKey(evt)
{
    var charCode = (evt.which) ? evt.which : event.keyCode
    if (charCode > 31 && (charCode < 48 || charCode > 57)) return false;
    return true;
}
return isNumberKey(editText)

I only have the onkey event property value to insert the code!

Your onkeypress="return isNumberKey(event)" function is sufficient to force user type only numerics.

Answer 2

Hi, Thank You for the assist.

But unfortunately struggling.

I have an onkeypress event where i can insert the code.

var edit = igedit_getById("FG2100RefNo");var editText = edit.getText();alert(!isNaN(editText));

Now this pops a message when true, but the above fuinction does not allow for any char to be typed.

I have no place to specify the javascript function and the call from the event code.

I tried: 1. return isNumberKey(event) 2. var edit = igedit_getById("FG2100RefNo");var editText = edit.getText();return isNumberKey(editText)

I think the problem is that it does not see the javascript function in order for to use.

Please Assist, Regards

You can provide the client function name to the control's ClientSideEvents.KeyPress property from the server-side.

C#:

FG2100RefNo.ClientSideEvents.KeyPress = "isNumberKey";

you'll have to update the definition of isNumberKey to accept the parameters provided and use the control's method of canceling the action.
