上decodeURIComponent

Question

意外的標記我有一個參數在我的Grails查看哪些我傳遞給JavaScript代碼

<g:if test="${replacedString}"> 
    ${replacedString} 
    <g:set var="replacedString" value="${replacedString}"/> 
</g:if> 
<script> 
    var mydata = decodeURIComponent(${replacedString}); 
    console.log(mydata); 
</script> 

的replacedString值被作爲編碼字符串，即通過：「顯示爲" 緣於此。我有

decodeURIComponent 

這是我試圖解碼字符串的方法：

[{"description":"test1 ","filenameAndPath":"test1.pdf"},{"description":"test file","filenameAndPath":"test copy.pdf"},{"description":"","filenameAndPath":""},{"description":"","filenameAndPath":""}] 

這段代碼不斷拋出錯誤Syntax error: Unexpected token &。
我錯過了一些明顯的東西嗎？

Answer 1

這是HTML編碼。

使用這一招從here： -

var encoded = "[{"description":"test1 ","filenameAndPath":"test1.pdf"},{"description":"test file","filenameAndPath":"test copy.pdf"},{"description":"","filenameAndPath":""},{"description":"","filenameAndPath":""}]" 
 

 
var elem = document.createElement('textarea'); 
 
elem.innerHTML = encoded; 
 
var decoded = elem.value; 
 

 
console.log(decoded);

見here是HTML格式的差異和URL編碼
