设置全局基本URL

Question

I'm using jQuery: which is the best way to store base url value for AJAX requests, in a way that every scripts can somehow reference it without manual changes for every update? Should I store it in window object, html, global variable, or what? Many thanks in advance.

You could create function to do it automatically:

var BASE_URL = 'http://www.foo.com/url-root/';

function getUrl(url) {
    return BASE_URL.concat(url);
}

Now, whenervar you want a url...

var url = getUrl('bar.php');  //returns 'http://www.foo.com/url-root/bar.php'

I you don't want it to be global...

(function() {
    var BASE_URL = 'http://www.foo.com/url-root/';

    window.getUrl = function(url) {
        return BASE_URL.concat(url);
    }
})();

Or you could create a object.
