从上面代码我想搜索标题并放置＆＃34; XXXXX＆＃34;如果它包含任何子标题（即标题1包含标题2），那么那时它应该放置＆＃34; XXXXX＆＃34;父母标题上方的单词而不是子标题。（标题1是父母）

任何人都可以帮助我。

Answer 1

THIS就是你想要的。

1）JQuery检查文档中的每个标题 2）然后搜索父母之前是否有另一个标题 3）如果父母之前没有标题，则在该标题之前添加内容。

$(document).find('h1, h2, h3, h4, h5, h6').each(function() {
    if ($(this).parent().prev().is('h1, h2, h3, h4, h5, h6') != true) {
        $(this).parent().before('<p>xxxxxxx</p>');
    }
});

Answer 2

我认为你需要这个代码

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<body>
  <DIV class="Find-Me">
    <H3 CLASS="Heading-1">First Level Heading</H3>  
    <DIV>
      <H4 CLASS="Heading-2">Second Level Heading</H4>
   <DIV>
   <H6 CLASS="Heading-3">Third Level Heading</H6>
   <P CLASS="Tab-Text-7">Some Text Here</P>
  </DIV>

  <DIV class="Find-Me">
   <H6 CLASS="Heading-3">Third Level Heading</H6>
   <TABLE>
     <TR>
      <TD ROWSPAN="1" COLSPAN="1">
       Some Cotents Here
      </TD>
     </TR>
   </TABLE>
</DIV>
  <script>
    function Insert() {
      $('<p>xxxx</p>').insertBefore('.Find-Me');
    }
    Insert();
    </script>
</body>

Answer 3

$('body > div').has([class^='Heading-']).prepend('XXXXXX');

找到这种类型的标题，然后在该div上方添加一个新单词
