jQuery - Show id, based on selected items class?
I have a layout roughly as follows:
<div id="foo">
<!-- a bunch of content -->
</div>
<div id="thumbnails">
<div class="thumb-co开发者_开发百科ntent1"></div>
<div class="thumb-content2"></div>
<div class="thumb-content3"></div>
</div>
<div id="content-1">
<!-- some text and pictures, including large-pic1 -->
</div>
<div id="content-2">
<!-- some text and pictures, including large-pic2 -->
</div>
<div id="content-3">
<!-- some text and pictures, including large-pic3 -->
</div>
etc ....
On page load I want to show 'foo' and 'thumbnails' and hide the three content divs.
As the user clicks each thumbnail, I want to hide foo, and replace it with the matching 'content-x'.
I can get my head round jQuery show, hide and replace (although, bonus points if you want to include that in your example!). But how would I extract and construct the appropriate content id, from the thumbnail class, then pass it to the show hide code?
Based on your markup, you can do something like this:
$("[id^=content]").hide();
$("#thumbnails > div").click(function() {
var id = $(this).attr('class').replace('thumb-content','');
$("#foo").html($("#content-"+id).html());
});
You can see a demo working here
This uses the ^=
starts-with selector to hide the initial divs, and on click, uses .html()
to copy the content like you want.
If you have a lot of these, it's better to use .delegate()
, which attaches a single event handler instead of n
event handlers to every click-able <div>
. It would look like this:
$("[id^=content]").hide();
$("#thumbnails").delegate("div", "click", function() {
var id = $(this).attr('class').replace('thumb-content','');
$("#foo").html($("#content-"+id).html());
});
Demo updated for that here
I just used the index from .each()
to construct the id name:
$("div[id^='content-']").hide();
$('#thumbnails').find('div').each(function(i,obj){
$(obj).click(function(e){
$("#foo").html($("#content-"+(i+1)).html());
});
});
...and you can see also a working demo here (Take that Nick!)
Load Content by means of class and id
<meta HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=ISO-8859-1">
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("jquery", "1.4.1");
google.setOnLoadCallback(function() {
// THIS IS WHAT YOU NEED (CALL IT ON LOAD)
$(function() {
$('.thumbs').click(function() {
var id = this.className.split(' ')[1];
$('#foo').html($('#' + id).html());
});
});
});
</script>
</head>
<body>
<div id="foo">
00 00 00
</div>
<div id="thumbnails">
<div class="thumbs content-1">Load 01</div>
<div class="thumbs content-2">Load 02</div>
<div class="thumbs content-3">Load 03</div>
</div>
<div id="content-1" style="display:none">
01 01 01
</div>
<div id="content-2" style="display:none">
02 02 02
</div>
<div id="content-3" style="display:none">
03 03 03
</div>
</body>
If I've read your post right, by clicking on the thumbs you want to load the content to #foo! If this is correct, use the example posted:
This will run the code every time you click on an element with a class of "thumbs"
$('.thumbs').click(function() {
This will split the classes of the clicked element and will grab to a variable the second one
var id = this.className.split(' ')[1];
This will search for an element with an id equal to the grabbed class and retrieve it's content, sending it to #foo.
$('#foo').html($('#' + id).html());
Note that the trick is to have the clicked element with a class name that's correspondent to and id element that contains the required content.
Hope this helps U!
