要每次页面加载时突出显示文本，请使用 for 循环和 −

<span class=”yourColorName”>

示例

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<style>
   .yellow {
      color: yellow;
   }
   .blue {
      color: blue;
   }
</style>
</head>
<body>
<h1 id="pageLoads">My yellow Words,your blue Words</h1>
<script>
   var ids = document.getElementById("pageLoads");
   var loadColorWords = ids.innerHTML.split(" ");
   for(var i = 0; i < loadColorWords.length; i++) {
      if(loadColorWords[i] == "blue") {
         loadColorWords[i] = "<span class='blue'>" + loadColorWords[i] + "</span>";
      }
      if(loadColorWords[i] == "yellow") {
         loadColorWords[i] = "<span class='yellow'>" + loadColorWords[i] + "</span>";
      }
   }
   ids.innerHTML = loadColorWords.join(" ");
</script>
</body>
</html>

要运行上述程序，请保存文件名anyName.html(index.html)并右键单击该文件并选择在 VS 代码编辑器中使用实时服务器打开选项。
