Jquery打开开关从外部链接

Question

我已经开发了这个切换菜单，它还显示每个主题的引用。我唯一不知道的是如何使用另一个页面的链接来切换特定的主题。下面的工作示例。谢谢你的关注。

jQuery( document ).ready( function( $ ) {
	   $(".faqs dd").hide();
    $(".faqs dt").click(function () {
        $(this).next(".faqs dd").slideToggle("slow").siblings(".faqs dd:visible").slideUp("slow");
        $(this).toggleClass("expanded");
		  $(this).siblings(".faqs dt").removeClass("expanded");
		
		
  if($(".faqs dt").hasClass("expanded") == true) {
         // hide open subcontents
        $('.subcontent:visible').hide();
		  $('.mainquote:visible').hide();
        // fade in new selected subcontent
        $('.subcontent[id='+$(this).attr('data-id')+']').delay(500).fadeIn();    
		 	 } else {
				  $('.subcontent:visible').hide(); } 
			 	
		     });	
			  });

dl dt,
dl dd {
  display:inline-block;
  *display:inline;
  font-weight: normal;
  vertical-align:top;
  float:left;
   width:100%;
}
.faqs dt, .faqs dd { padding: 0 0 0 30px; margin: 2px 0 0px 0;
	-ms-word-break: normal;
	word-wrap: normal;
	-webkit-hyphens: none;
	-moz-hyphens: none;
	hyphens: none; }
.faqs dt {font-weight:bold;}	
.faqs dt {cursor: pointer; background: url(http://www.evolvedstudio.com/plus_orange.png) no-repeat left; vertical-align:top; }
.faqs .expanded { background: url(http://www.evolvedstudio.com/minus_orange.png) no-repeat left; vertical-align:top; }
.subcontent {display:none; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="subcontent" id="123"><em>quote1</em></p></div>
<div class="subcontent" id="124"><em>quote2</em></p></div>
<dl class="faqs">
<dt data-id="123">Topic 1</dt>

Answer 1

捕获散列和

$(function(){
   var hash = window.location.hash.substr(1);
   showTopic(hash);
});
function showHash(s){
    if(s=="") return;
    $(".dt_"+s).trigger("click");
}

并将html改为

<dt data-id="123" class="dt_topic1">Topic 1</dt>
<dd>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
</dd>
<dt data-id="124" class=dt_topic2"">Topic 2</dt>
<dd>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</dd>

。只需在dt上添加一个类

并创建链接，如filename.html#topic1或filename.html#topic2
