Javascript: Remove WhiteSpace

function RemoveWhiteSpace()
{
var str = document.getElementById(‘TextBox1′).value;
str = str.replace(/^\s*(.*?)\s*$/, ‘$1′)
if (str == “”) {
alert(“Textbox value is empty.Please enter a valid username”);
return 0;
}
else {
return 1;
}
}

from HTML body call this javascript function like this.

Button ID=”Button1″ runat=”server” OnClientClick=”return RemoveWhiteSpace()==1″ Text=”Button”

Thanks,
Anil.
