validation code / function to allow only Letters in a text box



validation code / function to allow only Letters in a text box..

Answer / kevin konkle

//A script to format the Name field to only allow letters
//Have this be called off the keypress event of your
textbox control.
function nameFormat(fld, e)
{
var key = '';

//This string contains all characters you want to allow
//It could just as easily be 0123456789 to only allow
numbers.
var strCheck
= 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
var whichCode = (window.Event) ? e.which : e.keyCode;

if (whichCode == 13) return true; // Enter
if (whichCode == 8) return true; // Delete

// Get key value from key code
key = String.fromCharCode(whichCode);

// Not a valid key
if (strCheck.indexOf(key) == -1) return false;

//If it is a legal value then add it to the text box
fld.value += key;

return false;
}
