You need to do a global match, you can do this with a regex

var res = titleval.replace(/\s/g, "-");

Though String.prototype.replace does support having flags passed, this is deprecated in firefox and already doesn't work in chrome/v8.

BETTER IF, `var res = titleval.replace(/\s+/g, "-");` – Avinash Raj Apr 12 '16 at 11:27

Alternate method (if regex is not mandatory) could be to split and join

var res = titleval.split(" ").join("-");

or

var res = titleval.split(/\s+/).join("-");

@Guru, Why `.split` over `.replace` ? – Rayon Apr 12 '16 at 11:29
@RayonDabre yes agree, maybe this is truely the most trivial scenario to use split and join over replace. This is just an alternate method to do the same job, I guess. – gurvinder372 Apr 12 '16 at 11:31

Use regex with global flag

titleval.replace(/\s/g, "-");

try like this:

$("#title").keyup(function(){
 var titleval = $("#title").val();
 var res = titleval.replace(/\s+/g, '-');
 $("#newsurl").val(res);
});
