Question

I need to do validation for text with the following conditions.

• Numerics are not allowed.
• The allowed characters are: A-Z, a-z, apostrophe, space and hyphen.
• Does not contain Suffix

I am new to .Net and JavaScript. Can someone suggest how to do it?

Use the following code in your “keyup blur” event handler

$(function() {
    $('input.alpha[$id=tb1]'.bind('keyup blur', function() {
        if (this.value.search(/^[a-zA-Z]*$/) === -1) {
          alert("Only valid characters present");
        }
     }); 
});

Use + instead of * if you don’t want to allow empty matches for regex.
