我进入我的 html 文件参数，其中包含一些包含非英语字符的文本。像这样：http ://www.example.com/player.html?name=%e4%e1%ef

我需要将其解码为 name=הבן

我试过了：

unescape(url) - get wrong characters: name=äáï (maybe from another charset)
//and
decodeURIComponent(url) - get Malformed URI exception
// even found some solutions like
decodeURIComponent((url+'').replace(/\+/g, '%20')) - exception too

有什么解决办法吗？如何使用正确的字符集进行解码？

谢谢

我希望有一个简单的方法，但是在我得到更改网站的建议后，我以肮脏但有效的方式进行了操作。我的解决方案：

function decode(str) {
    str=str.split("%e0").join("א");
    str=str.split("%e1").join("ב");
    str=str.split("%e2").join("ג");
    str=str.split("%e3").join("ד");
    str=str.split("%e4").join("ה");
    str=str.split("%e5").join("ו");
    str=str.split("%e6").join("ז");
    str=str.split("%e7").join("ח");
    str=str.split("%e8").join("ט");
    str=str.split("%e9").join("י");
    str=str.split("%ea").join("ך");
    str=str.split("%eb").join("כ");
    str=str.split("%ec").join("ל");
    str=str.split("%ed").join("ם");
    str=str.split("%ee").join("מ");
    str=str.split("%ef").join("ן");
    str=str.split("%f0").join("נ");
    str=str.split("%f1").join("ס");
    str=str.split("%f2").join("ע");
    str=str.split("%f3").join("ף");
    str=str.split("%f4").join("פ");
    str=str.split("%f5").join("ץ");
    str=str.split("%f6").join("צ");
    str=str.split("%f7").join("ק");
    str=str.split("%f8").join("ר");
    str=str.split("%f9").join("ש");
    str=str.split("%fa").join("ת");
    str=str.split("%20").join(" ");
    return str;
}

原始网址未正确编码：

heb = "http://www.example.com/player.html?name=הבן"
"http://www.example.com/player.html?name=הבן"

enc = encodeURI(heb)
"http://www.example.com/player.html?name=%D7%94%D7%91%D7%9F"

decodeURI(enc)
"http://www.example.com/player.html?name=הבן"

免责声明：我没有对此代码进行任何彻底的测试

也就是说，它可以满足您的需求并且非常简单。使用来自unicode.org的转换表执行以下操作：

  1. 取消转义字符串
  2. 将每个字符拆分为一个数组
  3. 将每个字符转换为 Unicode 数字 (UTF-8)
  4. 将数组元素重新分配给相应的 unicode 编号 (iso_8859_8)
  5. 将数组转换回字符串

var url = "http://www.example.com/player.html?name=%e4%e1%ef;";
var string = '%e4%e1%ef';
