Question

<script>
var t5 ='<script>document.write(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'第五层\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\')<\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\/script>'
var t4 ='<script>document.write(\\\\\\\\\\\\\\\'第四层'+t5+'\\\\\\\\\\\\\\\')<\\\\\\\\\\\\\\\/script>'
var t3 ='<script>document.write(\\\\\\\'第三层'+t4+'\\\\\\\')<\\\\\\\/script>'
var t2 ='<script>document.write(\\\'第二层'+t3+'\\\')<\\\/script>'
var t1 ='<script>document.write(\'第一层'+t2+'\')<\/script>'document.write(t1)
</script>
这一段代码要刷新才可以看到变化

Answer 1

up 大家来关注一下嘛。
看看，两段原理一样的代码，得到不同的效果？为什么？代码一
<script>
var t4 ='<script>document.write(\\\\\\\\\\\\\\\'第四层'\\\\\\\\\\\\\\\')<\\\\\\\\\\\\\\\/script>'
var t3 ='<script>document.write(\\\\\\\'第三层'+t4+'\\\\\\\')<\\\\\\\/script>'
var t2 ='<script>document.write(\\\'第二层'+t3+'\\\')<\\\/script>'
var t1 ='<script>document.write(\'第一层'+t2+'\')<\/script>'document.write(t1)
</script>代码二
<script>
var t5 ='<script>document.write(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'第五层\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\')<\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\/script>'
var t4 ='<script>document.write(\\\\\\\\\\\\\\\'第四层'+t5+'\\\\\\\\\\\\\\\')<\\\\\\\\\\\\\\\/script>'
var t3 ='<script>document.write(\\\\\\\'第三层'+t4+'\\\\\\\')<\\\\\\\/script>'
var t2 ='<script>document.write(\\\'第二层'+t3+'\\\')<\\\/script>'
var t1 ='<script>document.write(\'第一层'+t2+'\')<\/script>'document.write(t1)
</script>

上面的代码有误，下面的正确，大家研究研究。看看，两段原理一样的代码，得到不同的效果？为什么？代码一
<script>
var t4 ='<script>document.write(\\\\\\\\\\\\\\\'第四层\\\\\\\\\\\\\\\')<\\\\\\\\\\\\\\\/script>'
var t3 ='<script>document.write(\\\\\\\'第三层'+t4+'\\\\\\\')<\\\\\\\/script>'
var t2 ='<script>document.write(\\\'第二层'+t3+'\\\')<\\\/script>'
var t1 ='<script>document.write(\'第一层'+t2+'\')<\/script>'document.write(t1)
</script>代码二
<script>
var t5 ='<script>document.write(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'第五层\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\')<\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\/script>'
var t4 ='<script>document.write(\\\\\\\\\\\\\\\'第四层'+t5+'\\\\\\\\\\\\\\\')<\\\\\\\\\\\\\\\/script>'
var t3 ='<script>document.write(\\\\\\\'第三层'+t4+'\\\\\\\')<\\\\\\\/script>'
var t2 ='<script>document.write(\\\'第二层'+t3+'\\\')<\\\/script>'
var t1 ='<script>document.write(\'第一层'+t2+'\')<\/script>'document.write(t1)
