The example of this article describes the implementation of the style replacement function of LI under UL based on regular expressions. Share it with everyone for your reference, the details are as follows:

First I thought of filling it under UL, but then I found that the result was not satisfactory and the style was not really changed:

$("#UlContent li").each(function (index) {
  // alert(index + &#39;: &#39; + $(this).text());
  var text = $(this).text();
  var regExp = new RegExp($("#search_content").val(), &#39;g&#39;);
  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；
});

In fact, it should be replaced before filling in UL:

$("#search_content").keyup(function () {
  if(CheckChinese($("#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(), &#39;g&#39;);
      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);
    }
   });
