All,
I have a javascript function that prevents users from entering non-numeric values into
a textbox.
I add the function to the onkeypress for the textbox in the code-behind page.
When I press any key, I am getting an 'object expected' error.
Here is the line of code in the code-behind page that adds the function call the
textbox:
txtUnitPrice.Attributes.Add("onkeypress", "javascript:return NumericOnly();")
And here is the javascript function:
function NumericOnly(){
var valid = "0123456789."
var testChar;
testChar = String.fromCharCode(event.keyCode);
if (valid.indexOf(testChar) == "-1") {
return false; }
else {
return true;
}
}
Doea anyone see what I am doing wrong?
Thanks,
Mark
