为什么先弹出 关注js高级篇 点确定后再显示 js进阶篇呢?
<script type="text/javascript">
document.write("JS进阶篇");
alert("关注JS高级篇");
</script>
<script type="text/javascript">
document.write("JS进阶篇");
alert("关注JS高级篇");
</script>

<script type="text/javascript">
document.write("JS进阶篇"+"<br>");
function tc(){
alert("关注JS高级篇");
}
</script>

<body>
<input type="button" value="点击我" onclick="tc()";/>
</body>
</html>
把document.write 内容输出命令 和 alert分开就好了
