[SOLVED] .search function

[cha0sriderx]

im trying to make a form that uploads screenshots for a game i play.  im trying to check the file type in javascript before the form even submits so that way i can do less checking after it does.  it says that gfiletype is jpg or png and yet matchtype is still -1

 

  gurl = document.screenshot.url.value;
  gurl2 = gurl.split(".");
  gfiletype = gurl2[gurl2.length - 1].toLowerCase();
  allowed = "png bmp jpg jpeg gif";
  matchtype = allowed.search(/ + gfiletype + /);
  alert(gfiletype +" / "+ matchtype);
  return false;

bump.

That's the right way to build a RegExp object.

that what i thought but for some reason its not working. any idea's why?

[cha0sriderx]

after getting really tired of the regexp not working i tried it a different way and it worked.  below is the code if anyone needs it

 

    var gurl = document.screenshot.image.value;
    var gurl2 = gurl.split(".");
    var gfiletype = gurl2[gurl2.length - 1].toLowerCase();
    var string1 = ["png", "bmp", "jpg", "jpeg", "gif"];
    var match = string1.indexOf(gfiletype);
