bootstrap 2.3.2在同一个页面使用多个弹出对话框时，点击几次之后弹出框会消失和不可用。
之前没发现，现在才知道。
下面这个代码bootstrap的加载load的方法。
<h3>This button shows a modal (<code>#utility</code>) with text "Phasellus <em>tincidunt gravida</em>..."</h3>
<br />
<a id="file_attach" data-toggle="modal" href="http://fiddle.jshell.net/jhfrench/6K8rD/show/" data-target="#utility" class="btn">Modal 1</a><br />
<h3>This button should invoke the same modal (<code>#utility</code>), but fill it with text "Phasellus <em>egestas est eu</em>..."</h3>
<br />
<a id="file_attach" data-toggle="modal" href="http://fiddle.jshell.net/jhfrench/AWSnt/show/" data-target="#utility" class="btn">Modal 2</a><br />
<!-- Modal -->
<div id="utility" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel">Click outside modal to close it</h3>
</div>
<div class="modal-body">
<p>One fine body…this is getting replaced with content that comes from passed-in href</p>
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
<button class="btn btn-primary">Save changes</button>
</div>
</div>$('a[data-toggle="modal"]').on('click', function(){ // update modal header with contents of button that invoked the modal $('#myModalLabel').html( $(this).html() ); //fixes a bootstrap bug that prevents a modal from being reused $('#utility_body').load( $(this).attr('href'), function(response, status, xhr) { if (status === 'error') { //console.log('got here'); $('#utility_body').html('<h2>Oh boy</h2><p>Sorry, but there was an error:' + xhr.status + ' ' + xhr.statusText+ '</p>'); } return this; } ); });
