找到attr（'href'）并在页面上打开隐藏的iframe，然后show（）iframe（jQuery + PHP）

Question

Language: PHP and jQuery

What I'm trying to do is pop up a dynamic link when a user clicks on it.
I don't want the page to be opened in a new window though, but in a modal one which overlays on the current page.

So with javascript, when a user clicks on this link, the action is to find the link's attr href and make a code for THAT link to be inside an iframe within the modal window.

The HTML with dynamic PHP link:

 <a href="http://www.facebook.com/share.php?u=<?php echo $root_url; ?>?id=<?php echo $rows['id']; ?>&title=<?php echo urlencode($rows['keyword']); ?>" style="border: none;" onclick="return false;" class="fblink" target="iframe"><img src="./img/Facebook.png" style="float: right; margin-top: 0px;" title="Share on Facebook" alt="Share on Facebook" id="<?php echo $rows['id']; ?>"></a>

The jQuery script :

    var makePop = function() {
    link = $(this).attr('href');
    return '<div class="the_box" id="box" style="display: block;"><a class="boxclose" id="boxclose"></a>
    <iframe src="' + link + '" height="500px" width="600px" id="" name="iframe"></iframe></div>';
    } // End of Function.

    $("a.fblink").click(makePop);

I don't know how to make this happen... This is not working.
Anybody? :o)

Answer 1

There's no point returning a string from an event handler function, it won't do anything.

You need to actually create the modal window. Try jQuery UI for this.

Answer 2

The following should provide what your looking for. However would need to consider issues such as same origin policy for the XHR 'load' call.

See example at: http://jsfiddle.net/qeXea/2/
Note: Due to same origin policy the iframe isn't able to populate with the content, simply setup your own page on your website and use your own urls to view.

HTML

<a href="http://www.yoururl.com" onclick="launchUrl(this); return false;">Click Here</a>
<div id="fade"></div>
<iframe id="dialog" src=""></iframe>
<script type="text/javascript">
function launchUrl(owner) {
    $('#fade').show();
    var link = $(owner).attr('href');
    $('#dialog').load(link, function(response) {
        $('#dialog').show();
    });
}
</script>

CSS

#fade {
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    z-index: 100;
    display: none;
    position: absolute;
    background-color: rgba(255, 255, 255, 0.5);
}

#dialog {
    top: 100px;
    left: 100px;
    width: 200px;
    height: 200px;
    z-index: 101;
    display: none;
    position: absolute;
}

<a href="" onclick="launchUrl('http://www.yoururl.com'); return false;">Click Here</a>
<div id="fade"></div>

        $('#fade').show();

        });
