var myurl = window.location;
    var pos = myurl.IndexOf("memberId");
    if (pos = -1) {
        alert("false");
    } else {
        alert("true");
     }

For some reason I can't seem to get this simple method to work. Chrome says 'myurl does not contain the method 'indexOf''. Any reason?

• javascript
• jquery
• html

• 3 if (pos = -1) shouldn't that be if (pos == -1)? – Razor Commented Dec 15, 2010 at 15:23
• 2 window.location is an object. Objects don't own the indexOf method. Even if you have a typo there, it wouldn't work either way. – jAndy Commented Dec 15, 2010 at 15:28

Maybe typo but it should be

myurl.indexOf

lowercase i.

And location is an object, so you want:

var myurl = window.location.href;

(and all the other things people say in the ments and other answers ;))

Update: To see what kind of properties an object has, just type, in this case, window.location in the console:

window.location returns an object. Perhaps you wanted window.location.pathname? :-)

There's also a problem with this line:

if (pos = -1)

It should be

if (pos == -1)

try var myurl = window.location.pathname;

var myurl = window.location.toString();
