The following code needs to be refreshed after running in order to load jquery

<div> </div> <div>John Resig</div> <div>George Martin</div> <div>Malcom John Sinclair J. Ohn <br> <input onclick="runEx('runcode34443')" type="button" value="运行代码"><input onclick="doCopy('runcode34443')" type="button" value="复制代码"><input onclick="doSave(runcode34443)" type="button" value="保存代码"> <a href="http://www.jb51.net/article/23421.htm" title="查看具体详情" target="_blank"> </a>[Ctrl A Select all Note: </div>If you need to introduce external Js, you need to refresh to execute <br>]<br><br><div class="codetitle">In jQuery Two useful custom selectors: odd and :even. For example, the following code can set the odd and even rows of the table to have different styles: <span><a style="CURSOR: pointer" data="26157" class="copybut" id="copybut26157" onclick="doCopy('code26157')"><u></u></a>Copy the code </span> </div> <div class="codebody" id="code26157"> The code is as follows: <br><br> <br>$(document).ready(functioin() { <br><br>　$("tr:odd").addClass("oddstyle"); <br><br>　$("tr:even" ).addClass("evenstyle"); <br> </div>}); <br><script src="http://code.jquery.com/jquery-latest.js"></script> <script> $(document).ready(function(){ $("div:contains('John')").css("text-decoration", "underline"); }); </script>Among them, tr:odd selects all the odd rows in the table, and then adds the style oddstyle; tr:even Select all even rows in the table and add style evenstyle. Of course, oddstyle and evenstyle must be defined in the css file first.
