javascript - 网址解码 - 不起作用

Question

为什么以下解码脚本不起作用？原始代码似乎运行得很好。

javascript:(function(s){try{s=document.selection.createRange().text}catch(_)  {s=document.getSelection()}prompt('State the question and answer below.','Q.' s '')})

原始代码：

javascript:%28function%28s%29%7Btry%7Bs=document.selection.createRange%28%29.text%7Dcatch%28_%29%7Bs=document.getSelection%28%29%7Dprompt%28%27State the question and answer below.%27,%27Q.%27+s+%27%27%29%7D%29%28%29

首先十分感谢。

Answer 1

它将符号解码+为一个空格，试试这个：

javascript:(function(s){try{s=document.selection.createRange().text}catch(_)  {s=document.getSelection()}prompt('State the question and answer below.','Q.'+s+'')})

区别：改成' s '这个'+s+'

Answer 2

不要取消转义 + 符号并将 () 添加到末尾：

javascript:(function(s){try{s=document.selection.createRange().text}catch(_)  {s=document.getSelection()}prompt('State the question and answer below.','Q.' s '')})
should be
javascript:(function(s){try{s=document.selection.createRange().text}catch(_){s=document.getSelection()}prompt('State the question and answer below.','Q.'+s+'')})()
