Find element's attribute value
提问by tanya
I have got the following code :
我有以下代码：
<ul>
<li class="jstree-leaf" kids="0" range="5-7" name="mars" public_id="mars_05" ra_depth="5">
<a href="#"><ins class="jstree-icon"> </ins>mars</a>
</li>
<li class="jstree-leaf" kids="0" range="8-10" name="pluto" public_id="pluto_8" ra_depth="5">
<a href="#"><ins class="jstree-icon"> </ins>pluto</a>
</li>
</ul>
I need to get the ra_depthattribute value of a particular <li>by using it's nameattribute value.
我需要通过使用它的属性值来获取ra_depth特定<li>的name属性值。
I tried the code below but it's not working:
我尝试了下面的代码，但它不起作用：
alert(li[name='"+myarray[0]+"'].attr("ra_depth"));
myarray[0]contains the value "pluto".
myarray[0]包含值“冥王星”。
Is there anything I am missing?
有什么我想念的吗？

You are missing the actually jQuery function around your selector:
您缺少选择器周围的实际 jQuery 函数：
alert($("li[name='"+myarray[0]+"']").attr("ra_depth"));
回答by Rajeev Beakta
you missed the element seletor here.Try this
你在这里错过了元素选择器。试试这个
alert($("li[name='"+myarray[0]+"']").attr("ra_depth"));
alert($("li[name='"+myarray[0]+"']").attr("ra_depth"));
