Hi,
I am trying to validate value put in by customer in the text box. I want to catch if they put in "'" as don't want them enter "'". Is there any built in javascript function that will let me to that. Or I will have to write some function myself.

Thanks

I think you will have to write a function yourself, such as this:

function validateTextBox(textBox)
{
 if(textBox.value.indexOf("'") != -1 || textBox.value.indexOf("\"") != -1)
 {
  backspace(textBox);
 }
}

function backspace(textBox)
{
 textBox.value = textBox.value.substr(0,textBox.value.length - 1);
}

...

<input type=text onchange=validateTextBox(this)>

Let me know if this helps you.
