我的alert没有跳出来，帮我看下是哪里错了呢？

Question

<div id="content"></div>

<script type="text/javascript">

var content=document.getElementById("content");

// var str = "_<script defer>alert('hi');<\/script>";

var str="<input type=\"hidden\"><script defer>alert('hi');<\/script>";

content.innerHTML=str;

</script>

Answer 1

为什么注释var str；<script></script>结束标签写错;alert简单语法基本不会有问题
