js代码解释:
当点击 <a href="#" style="cursor: hand" onclick="more(this);" class="fright mr15">更多</a>时, 在js的函数中想要获取隐藏域的值 <input type="hidden" value="00070008" id="levelCode" /> <input type="hidden" value="100000001811" id="columId" /> onclick="more(this);"这里的this 指的是当前dom元素 <a></a>标签 在js的函数function more(thisObj){...}中, 1.$(thisObj)获取<a></a>的jquery对象, 2.$(thisObj).parent(),获取到<a></a>的父对象<div class="sx_title">...</div> 3.$(thisObj).parent().next() 获取到<div class="apps_container">jquery对象 4.$(thisObj).parent().next().children("ul") 获取到<ul class="apps_list1_1">jquery对象 5.$(thisObj).parent().next().children("ul").children("input").eq(0) 获取到<ul class="apps_list1_1">下面的第一个<input>元素:<input type="hidden" value="00070008" id="levelCode" /> 6.$(thisObj).parent().next().children("ul").children("input").eq(0).val(); 获取到<input type="hidden" value="00070008" id="levelCode" />的value值 :00070008 7.$(thisObj).parent().next().children("ul").children("input").eq(1).val(); 获取到<ul class="apps_list1_1">下面的第二个<input>元素, <input type="hidden" value="100000001811" id="columId" />的值:100000001811 8.$(thisObj).parent().prev()获取到<span></span>jquery对象 9.$(thisObj).parent().prev().html()获取到<span></span>的内容<input type="hidden" value="1" id="newInfo"></input> 10.$(thisObj).parent().prev().children("input").eq(0).val()获取 <span></span>下面的第一个<input>的值,其实就一个<input>元素,即:1
