val = 'Whatever%'; //or %Whatever
val.replace('%', '');
var finalstring = val.replace(/^\s+|\s+$/g,''); //trimming

If I got you well,

var val = "%Hello"
var reg= new RegExp ("%");
val = val.replace (reg, "");

should work. (I call regexp to show you the good way if you show up with more complicate examples). But

var val = "%Hello";
val = val.replace ("%", "");

will be faster.

Simply replace the % character with a blank string.

var val = "%Hello";
val = val.replace('%', '');
alert(val); //alerts "Hello"

var val = "Hello%";
val = val.replace('%', '');
alert(val); //alerts "Hello"

var val = "%Hello%";
val = val.replace('%', '');
