html中嵌入js为什么不能输出

问题描述

如下<ahref="/team/buy2.php?id={$one['id']}&is_fox=<script>document.write(is_fox)</script>"class="en-btn"target="_blank">

得到结果：http://www.xxx.com/team/buy2.php?id=ZTNDczMg==&is_fox=<script>document.write(is_fox)</script>

而改成：<script>document.write("<ahref="/team/buy2.php?id={$one['id']}&is_fox="+is_fox+"class="en-btn"target="_blank">");</script>

可以输出了，但是得到结果：http://www.xxx.com/team/buy2.php?id=ZTNDczMg==&is_fox=0class=

都是错误的，我想得到http://www.xxx.com/team/buy2.php?id=ZTNDczMg==&is_fox=0怎么改

解决方案

解决方案二：
<script>document.write("<ahref="/team/buy2.php?id={$one['id']}&is_fox="+is_fox+""target="_blank">");</script>

解决方案三：
http://www.xxx.com/team/buy2.php?id=ZTNDczMg==&is_fox=<script>document.write(is_fox)</script><>()/在URL里面要用转义字符的
