Rails 3 - Ajax - Need help with some basic Javascript/Jquery

I'm trying to learn some javascript and have gotten stuck.

Right now, I have a really stupid simple gallery/image application. What I'm trying to do is make it so, when someone clicks an image, it hyperlinks them to a url I have in my model data all with ajax. The reason why is I'd like to also do something with ajax, like update a score/vote counter for the image when it is clicked.

Right now in the view I do this with:

<% @galleries.each do |g| %>
    <% for image in g.images %>
    <div id="picture">
      <%= render 'top_nav'%>

      <%= link_to image_tag(image.file_url(:preview)), g.source, :remote => true, :target => "_blank" %>

So far, with javascript I've figured out how to open a url, but only if I hardcode one into the javascript. Here's my index.js.erb code (real simple):

window.open("http://www.go开发者_运维百科ogle.com");

But I cannot figure out how I would link to my g.source like I am in my view's do loop. How do I access this model data in javascript? I have figured out how to render this code on click of the image though, with the follow in ...javascripts/application.js:

$(function() {
    $("#galleries #picture a img").live("click", function() {
        $.getScript(this.href);
        return false;
    });
});

Anyone have any pointers on how I can start interacting with my application's data rather than hardcoding a url in the open?

Thanks

You are pretty much on the right path to open image in a window, if the href you get from a points to image file.

Try with this code:

$(function() {
    $("#galleries #picture a img").live("click", function() {
        var lnk = $(this).closest("a").attr("href");
        window.open(lnk);
        return false;
    });
});

"#galleries #picture a img" is giving you img elements but you need the hyperlink which contains the image. so we will use $(this).closest("a") to get hyperlink for image url.
