You can define a
trim
function which trims leading and trailing space in JavaScript by using any one of the following ways:
way 1:
String.prototype.trim = function() { return this.replace(/^\s+|\s+$/g, ''); }
way 2:
function trim()
{
return this.replace(/^\s+|\s+$/g, '');
}
The following function shows how to use the trim
function
function temp()
{
var str=' maninder ';
alert(str.trim());
}
You will see
'maninder' in the alert box. All the leading and trailing space are trimmed. :)
