Question

You may have see various sites where URLs are encoded by an advertisement redirection service. I want to write a personal javascript snippet to remove this spam.

Mostly, the HTML will look like this:

<a target="_blank" href="http://ads.example.com/246619/http://www.example.net/path/I/want">SteamTable App</a>

The problem is that the URL path http://ads.example.com/246619/ is different for each link.

My attempt:

$(function() {
    var x = $('div.content.clearfix a').get();
    //alert(x.length);
    for (i = 0; i < x.length; i++) {
        var Href = $(x[i]).attr('href');

        Href = Href.replace("http://ads.example.com/.*?/", "");
        alert(Href);  //success or not
        $(x[i]).attr('href', Href);
    }
});

Demo on JS Fiddle.

I don’t know why this isn’t working.

Remove the quotes around your regex and use regex delimiters

Href = Href.replace(/http:\/\/url.sh\/.*?\//, "");
