根据活动类获取数据属性的值 [英] fetch the value of data-attribute based on active class
问题描述
我想基于
ul > li class = "activeTab"
这是我的代码.
<ul class="tabs">
<li data-itemtype="1" class="activeTab"><a href="#tab1">Published</a></li>
<li data-itemtype="0" class=""><a href="#tab2">Unpublished</a></li>
</ul>
如果class="activeTab"
在第一个<li>
元素中,则获取第一个li元素的数据属性,即在这种情况下为1,因此对于第二个或任意数量的li元素同样适用.
if class="activeTab"
is in first <li>
element then fetch the data attribute of first li element i.e 1 in this case and hence same applies for the second or any number of li elements.
我尝试过
var itemType = $('ul.tabs').find('li.activeTab').attr('data-itemtype');
,它不起作用.它显示了未定义的值.
and it does not work. it shows value undefined.
更新:
我正在使用标签.我想知道哪个标签当前处于活动状态,我需要在javascript变量中使用该值.
i am using tabs. i want to know which tab is currently active and i need that value in javascript variable.
这是我的HTML代码.
here is my HTML code.
<div class="widget">
<ul class="tabs">
<li data-itemtype="1"><a href="#tab1">Published</a></li>
<li data-itemtype="0"><a href="#tab2">Unpublished</a></li>
</ul>
<div class="tab_container">
<div id="tab1" class="tab_content">
<div class="widget" style="margin-top:0px;">
<div class="title"><img src="/images/icons/dark/cart3.png" alt="" class="titleIcon" /><h6>Published Items</h6></div>
<p>Content</p>
</div>
</div>
<div id="tab2" class="tab_content">
<div class="widget" style="margin-top:0px;">
<div class="title"><img src="/images/icons/dark/cart3.png" alt="" class="titleIcon" /><h6>Unpublished Items</h6></div>
<p>Content</p>
</div>
</div>
</div>
<div class="clear"></div>
</div>
正在使用的jQuery是这个.
the jQuery being used is this.
$.fn.contentTabs = function(){
$(this).find(".tab_content").hide(); //Hide all content
$(this).find("ul.tabs li:first").addClass("activeTab").show(); //Activate first tab
$(this).find(".tab_content:first").show(); //Show first tab content
$("ul.tabs li").click(function() {
$(this).parent().parent().find("ul.tabs li").removeClass("activeTab"); //Remove any "active" class
$(this).addClass("activeTab"); //Add "active" class to selected tab
$(this).parent().parent().find(".tab_content").hide(); //Hide all tab content
var activeTab = $(this).find("a").attr("href"); //Find the rel attribute value to identify the active tab + content
$(activeTab).show(); //Fade in the active content
return false;
});
};
$("div[class^='widget']").contentTabs(); //Run function on any div with class name of "Content Tabs"
上面的代码对我不起作用.
the above code does not work for me.
推荐答案
似乎工作正常.
我会改用.data(...)
:
var itemType = $('ul.tabs').find('li.activeTab').data('itemtype');
alert(itemType);
