基于正则表达式实现UL下LI的样式替换功能

$("#UlContent li").each(function (index) {  // alert(index + ': ' + $(this).text());  var text = $(this).text();  var regExp = new RegExp($("#search_content").val(), 'g');  var newText = text.replace(regExp,"<span style=/"background-color:red;/">" + $("#search_content").val() + "</span>");//将找到的关键字替换，加上highlight属性；  $(this).text(newText);//更新文章；});

$("#search_content").keyup(function () {  if(CheckChinese($("#search_content").val()))  {   $.ajax({    type: "POST",    anync: true,    url: "HelpCenterSuggestion.ashx",    cache: false,    dataType: "text",    data: { m: $("#search_content").val() },    success: function (result) {     $("#UlContent li").remove();      var regExp = new RegExp($("#search_content").val(), 'g');      var newText = result.replace(regExp,"<span style=/"background-color:red;/">" + $("#search_content").val() + "</span>");//将找到的关键字替换，加上highlight属性；      $("#UlContent").append(newText);    }   });
