Learning Regular Expression Syntax

http://www.radsoftware.com.au/articles/regexlearnsyntax.aspx

Javascript : Allow only Numeric in Textbox

function validNum(o)
{
if(event.keyCode != 37 && event.keyCode != 39)
o.value = o.value.replace ( /[^0-9]/g, "" );
}

Convert string to TitleCase

string strSample = "MOHAN";
strResult = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo.ToTitleCase(strSample.ToLower());
// Answer : strResult = "Mohan"

Javascript: Regular Expression to replace '-' to ','

function fnReplace()
{
var rExp = /-/gi;
var strX = '1,2,3,5-6,4-3-5-4';
alert(strX.replace(rExp,','));
}
