jquery - 使用嵌套 div 将类添加到 tr

Question

我正在尝试使用 jquery 将类添加到 tr .inside 类名称为 .flexme1 的表中

我尝试了下面的各种选项，但似乎没有用..

  //jQuery("div.flexigrid > table.flexme1 > tr").addClass("cal");

or

        jQuery("div.flexigrid > table.flexme1 > tr").addClass("sev1");
  or 
        jQuery(".erow").addClass("sev2");
   or
        jQuery(".flexigrid > tr").addClass("sev3");
   or
        jQuery(".flexigrid >tr").addClass("sev4");
   or
        jQuery(".flexigrid >tr").addClass("sev5");

我希望 tr 添加 class="somename" 。

<div class="flexigrid">
  ..< some other divs>...<<table> ..</table></div>
... <some other divs>...<table>..</table></div>

Answer 1

这样做： -

jQuery(".bDiv table.flexme1 tr").addClass("inside");

参考现场演示

Answer 2

你几乎是对的，只需删除>- 这table不是他们之间的直接孩子：.flexigriddiv.bDiv

jQuery("div.flexigrid table.flexme1 tr").addClass("somename");
