Show/Hide span on the same spot

问题

I am using jQuery to show or hide a span. But I want the <div> to appear in the same place as the link I click. The current code actually shows the <div> tags on the left side of the screen. Here is the code i am using.

<script>
$(document).ready(function(){
    $(".slidingDiv").hide();
    $(".show_hide").show();
    $('.show_hide').click(function(){
    $(".slidingDiv").slideToggle();
      return false;
    });
    $(".slidingDiv1").hide();
    $(".show_hide1").show();
    $('.show_hide1').click(function(){
    $(".slidingDiv1").slideToggle();
      return false;
    });
});
</script>

Span Tag:

<span>
 <a href="#" class="show_hide">Japan</a>
 <span class="slidingDiv">
   <img src="02-1 ImageFiles/01 Japan.JPG" style="width:235px; height:245px;">
   <a href="#" class="show_hide">Close</a>
 </span>
 is made up of islands, regions, prefectures (government districts), cities, and surrounding communities. The main island, Honshu, has thirty-four prefectures making up five regions. The 
 <a class="show_hide1" href="#">Tōhoku Region</a>
 <span class="slidingDiv1">
  <img src="02-1 ImageFiles/02 TohokuRegion.JPG" style="width:217px; height:236px;">
  <a href="#" class="show_hide1">Close</a>
</span>

this can be your HTML part:

<a href="#" class="show_hide" style="position: relative;">Japan</a>
<span class="slidingDiv" style="position: absolute; left: 0;">
    <img src="02-1 ImageFiles/01 Japan.JPG" style="width: 235px; height: 245px;" />
    <a href="#" class="show_hide_close">Close</a>
</span>
is made up of islands, regions, prefectures (government districts), cities, and surrounding communities. The main island, Honshu, has thirty-four prefectures making up five regions. The
<a class="show_hide" href="#" style="position: relative;">T&#197;hoku Region</a>
<span class="slidingDiv" style="position: absolute; left: 0;">
    <img src="02-1 ImageFiles/02 TohokuRegion.JPG" style="width: 217px; height: 236px;" />
    <a href="#" class="show_hide_close">Close</a>
</span>

and this can be your script part:

<script type="text/javascript">
    $(document).ready(function () {
    $(".slidingDiv").hide();
    $(".show_hide").show();

    $('.show_hide').click(function () {
        var el = $(this);
        var slidingDiv = el.find("span.slidingDiv");
        if (slidingDiv.length > 0) {
            slidingDiv.slideToggle(function () { el.after(slidingDiv); });
        }
        else {
            slidingDiv = el.next("span.slidingDiv");
            el.append(slidingDiv);
            slidingDiv.slideToggle();
        }
        return false;
    });
    $('.show_hide_close').click(function () {
        $(this).parent().parent("a.show_hide").click();
        return false;
    });
});

Explanation:

the script will append the span to the anchor on click and will move it back to its original place on closing. the reason is that you cannot wrap a block (here is the span) in an anchor tag in the html code, so we will do it at run-time. and we should wrap it because we need to show the span below the anchor tag.
span containing the img and close button should have absolute position
anchor which will be clicked should have relative position so browser can calculate the position of the span from the parent anchor, so it will be now below the link
I generalized anchor and span classes, so you can use it with only one script block
different class has been assigned to the close button, so clicking it will click the parent anchor

回答2:

Remove the div and Set the span to display: block

<a href="#" class="show_hide">Japan</a>
<a href="#" class="show_hide">Close</a>
<span class="slidingDiv">
    <img src="02-1 ImageFiles/01 Japan.JPG" style="width:235px; height:245px;" />    
</span>

span
{
   display: block;
}
