使用jQuery在div中加载页面

Question

This jQuery code loads a specific page within a div (this works):

    <script type="text/javascript">
        $(document).ready(function() {

            $("#button2").on("click", function(){  
                $("#loader").load($("#button2").attr("page"));
                return false;
            });
        });
    </script>

Also, I have 2 links with an attribute "page" indicating the html file to be loaded in the div:

<li><a href="#" title="" id="button2" page="page1.html">Link 1</a></li>
<li><a href="#" title="" id="button2" page="page2.html">Link 2</a></li>

This is the div where the page is loaded:

<div id="loader"></div>

The problem is that only loads "page1.html" when I click on the first link. If I click on the second link does not load "page2.html".

I think it may be a problem of the id attribute of link "button2" on repeat maybe something happens.

What am I doing wrong?

Thank you!

Answer 1

You must not use same ids for elements. Each id attribute must be unique (according to HTML4.01 and HTML5 specs).

It would be better to use a class to identify these buttons instead, like this:

<script type="text/javascript">
    $(document).ready(function() {

        $(".buttons").on("click", function(){  
            $("#loader").load($(this).attr("page"));
            return false;
        });
    });
</script>

and the button's HTML:

<li><a href="#" title="" class="buttons" page="page1.html">Link 1</a></li>
<li><a href="#" title="" class="buttons" page="page2.html">Link 2</a></li>

"What am I doing wrong?"

You are using duplicate ID's, which is forbidden in HTML. Use a class name or an element selector instead. You can refer to the currently clicked button inside the event handler by $(this) :

<li><a href="#" title="" class="button" page="page1.html">Link 1</a></li>
<li><a href="#" title="" class="button" page="page2.html">Link 2</a></li>

$(".button2").on("click", function(){  
    $("#loader").load($(this).attr("page"));
    return false;
});
