Jquery: conditionally add class if the url contains a specific hash value

How can I add a conditional statement that says something like

if(window.location.href.indexOf("#/brand开发者_StackOverflow社区partners"))
    {
    $("#brandpartners").addClass("specialbrand");
    }

The hash seems to break the statement. Is there a better way?

First of all, you can't use indexOf that way. It returns -1, when it's not found which isn't false.

It makes a lot more sense to me to just use the built-in parsing of the hash value in the location object. I'd suggest doing it this way:

if (window.location.hash == "#brandpartners") {
    $("#brandpartners").addClass("specialbrand");
}

I don't know your URL structure, but there shouldn't be a need for a slash after the # for a simple hash value. But, if you insist on using the slash, it would look like this:

if (window.location.hash == "#/brandpartners") {
    $("#brandpartners").addClass("specialbrand");
}

The hash (#) isn't breaking the statement at all for me. But I don't know exactly why you have the / in there when you don't need it.

var str = "http://stackoverflow.com/questions/6950161#hmenus";
alert(str.indexOf("#hmenus"));

This code alerts 42, which means it should do what you want. I

As @jfriend00 sais, it should be:

if(window.location.href.indexOf("#/brandpartners")!=-1)
            {
$("#brandpartners").addClass("specialbrand");
            }

indexOf() returns -1 if the string is not found, which evaluates as "truthy" such that your if statement isn't doing what you think it is. So try:

if (window.location.href.indexOf("#/brandpartners") != -1) {}
