Remove everything after a certain character

Question

Is there a way to remove everything after a certain character or just choose everything up to that character? I'm getting the value from an href and up to the "?", and it's always going to be a different amount of characters.

Like this

/Controller/Action?id=11112&value=4444 

I want the href to be /Controller/Action only, so I want to remove everything after the "?".

I'm using this now:

 $('.Delete').click(function (e) {      e.preventDefault();       var id = $(this).parents('tr:first').attr('id');                      var url = $(this).attr('href');       console.log(url);  } 

Answer 1

var s = '/Controller/Action?id=11112&value=4444'; s = s.substring(0, s.indexOf('?')); document.write(s);

I should also mention that native string functions are much faster than regular expressions, which should only really be used when necessary (this isn't one of those cases).

Updated code to account for no '?':

var s = '/Controller/Action'; var n = s.indexOf('?'); s = s.substring(0, n != -1 ? n : s.length); document.write(s);

Answer 2

You can also use the split() function. This seems to be the easiest one that comes to my mind :).

url.split('?')[0]

One advantage is this method will work even if there is no ? in the string - it will return the whole string.
