问题
I have an id'd part of a child HTML file loaded into the parent HTML's div. I have a button at the top to empty out the child content and return the div to the parent content that was there previously. This is for an image gallery, with a main navigation (parent) and then the detailed view with smaller navigation (child). Here is the parent HTML, index.html (with CSS and JS embedded):
<html>
<head>
<title>Java Factory</title>
<script type="text/javascript" src="js/jquery-1.7.1.min.js"></script>
<style type="text/css">
#container {
width: 1020px;
height: 634px;
}
ul#flavors {
list-style: none;
width: 1020px;
height: 634px;
position: relative;
background: url(images/coffee/thumbs_large.jpg) no-repeat 0 0;
}
ul#flavors li {
position: absolute;
}
.wakey {
width: 309px;
height: 309px;
top: 0px;
left: 30px;
}
.smooth {
width: 309px;
height: 309px;
top: 0px;
left: 355px;
}
ul#flavors li a {
display: block;
outline: none;
height: 100%;
}
ul#flavors li a {
text-indent: -9000px;
}
ul#flavors li a:hover {
background: url(images/coffee/thumbs_large.jpg) no-repeat 0 0;
}
ul#flavors li.wakey a:hover {
background-position: -30px -640px;
}
ul#flavors li.smooth a:hover {
background-position: -355px -640px;
}
#top {
height: 36px;
margin-top: 10px;
margin-bottom: 10px;
}
</style>
</head>
<body>
<div id="web">
<div id="top">
</div>
<nav id="container">
<ul id="flavors" class="coffeenav">
<li class="wakey"><a href="#wakey">Wakey Wakey</a></li>
<li class="smooth"><a href="#smooth">Smooth Caffeinator</a></li>
</ul>
</nav>
</div>
<script type="text/javascript" charset="utf-8">
$(document).ready(function () {
$('#web').on('click', '.coffeenav li a', function () {
$('#web').load('coffee.html #' + $(this).attr('href'));
return false;
});
});

The button inside each referenced div id in the child HTML is this:
<div id="coffee_return">
<a href="x"><img src="images/coffee/return_btn.jpg" border="0"></a>
</div>
And the demo for this is: http://mmdsgn.com/divsample/5/ -- You'll see the return button appears at the top when you click either of the first two boxes (only ones that work right now) and I need that graphic button to call up the original div id content in the parent HTML.
回答1:
Change the path on "href" to "../" instead of "x"
<a href="../"><img src="images/coffee/return_btn.jpg" border="0"></a>
or remove it. Using # is not really recommended since your script looks for the content of href. So leaving it empty would cause the page to refresh? i'm not quite sure but it works.
<a href=""><img src="images/coffee/return_btn.jpg" border="0"></a>
Edit: Now that i think about it. The first one would not work on your page since you are in the same folder. ;-)
回答2:
You'll want to change your original script a bit:
<script type="text/javascript" charset="utf-8">
$(document).ready(function () {
$('#web').on('click', '.coffeenav li a', function () {
$('#web').load('coffee.html #' + $(this).attr('href'),
function() {
$('#coffee_return').on('click', function () {
$('#web').load('./ #web');
return false;
});
});
return false;
});
});
</script>
This basically says: After loading a section of coffee.html, look for a coffee_return button and add onclick behavior to re-load the original page into your #web section.
Also, change that href on your coffee_return button to # or JavaScript:void(0); since it's trying to load a document called "x" currently:
<div id="coffee_return">
<a href="#"><img src="images/coffee/return_btn.jpg" border="0"></a>
</div>
回答3:
You cannot use same id on multiple elements, as you said "
The button inside each referenced div id in the child HTML is this:
<div id="coffee_return">
<a href="x"><img src="images/coffee/return_btn.jpg" border="0"></a>
</div>
". This would give erroneous results. Rather, assign them a class and bind event with their class.
