Change url params string using JavaScript

Question

I want to remove some params from a URL string:

For Example:

I have a string like this:

var url = '/browse/102?color=red&type=car&rpp=10&ajax=1&change=1';

and an array like this:

var ignore = new Array("change","ajax"); 

Result:

/browse/102?color=red&type=car&rpp=10

What is the shortest and quickest way to achieve this?

Answer 1

What about a RegExp? Here is an example function:

var url = '/browse/102?color=red&type=car&rpp=10&a=mode&ajax=1&change=1&mode&test';
var ignore = new Array("change","ajax", "mode", "test"); 
alert(removeParams(url, ignore));

function removeParams(address, params)
{
    for (var i = 0; i < params.length; i++)
    {
       var reg = new RegExp("([\&\?]+)(" + params[i] + "(=[^&]+)?&?)", "g")
       address = address.replace(reg, function($0, $1) { return $1; });
    }
    return address.replace(/[&?]$/, "");
}​

Edit: Moved to a separate function like Michal B. did.
