Question

我正在尝试使用jquery将类添加到带有类名.flexme1

的表中的tr。

我尝试了下面的各种选项，但似乎没有工作..

  //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拥有class =＆＃34; somename＆＃34;添加到它。

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

Answer 1

你几乎是正确的，只是remove the > - table不是.flexigrid div.bDiv，因为它们之间还有另一个jQuery("div.flexigrid table.flexme1 tr").addClass("somename");：

{{1}}

Answer 2

这样做： -

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