How to remove a particular element from an array in JavaScript?

I have an array of integers, which I'm using the .push() method to add to.
Is there a simple way to remove a specific element from an array? The equivalent of something like array.remove(int);.
I have to use core JavaScript - no frameworks are allowed.

Answer: 

First, find the index of the element you want to remove:
var array = [2, 5, 9];
var index = array.indexOf(5);
Note: browser support for indexOf is limited; it is not supported in Internet Explorer 7 and 8.
Then remove it with splice:
if (index > -1) {
    array.splice(index, 1);
}
The second parameter of splice is the number of elements to remove. Note that splice modifies the array in place and returns a new array containing the elements that have been removed.

If you need indexOf in an unsupported browser, try the following polyfill. Find more info about this polyfill here.
Array.prototype.indexOf || (Array.prototype.indexOf = function(d, e) {
    var a;
    if (null == this) throw new TypeError('"this" is null or not defined');
    var c = Object(this),
        b = c.length >>> 0;
    if (0 === b) return -1;
    a = +e || 0;
    Infinity === Math.abs(a) && (a = 0);
    if (a >= b) return -1;
    for (a = Math.max(0 <= a ? a : b - Math.abs(a), 0); a < b;) {
        if (a in c && c[a] === d) return a;
        a++
    }
    return -1
});
