Regexp刪除URL中的所有特殊字符

Question

我需要基本清理其中包含特殊字符的網址，如下所示：

http://172.23.113.79/recherche/pages/Results.aspx?k=**cr%c3%83%c2%a9er***

我想用**cr%c3%83%c2%a9er*** **créer**替換**cr%c3%83%c2%a9er***

而且更À Á Â à á â È É Ê è é ê Ì Í Î ì í î Ò Ó Ô ò ó ô Ù Ú Û ù ú û是所有角色，比如À Á Â à á â È É Ê è é ê Ì Í Î ì í î Ò Ó Ô ò ó ô Ù Ú Û ù ú û 。

var u=decodeURI("http://172.23.113.79/recherche/pages/Results.aspx?k=cr%C3%A9er*");

如果它不是非常通用的並且您有要替換的特殊字符和短語，則可以將特殊字符/短語映射到其替換，然后解碼字符串並替換它們中的每一個：

var replacements = {
    "créer" : "créer", // this is a phrase
    "Ã" : "é",
    "Â" : "e",
    "©" : ""
};
var url = "http://172.23.113.79/recherche/pages/Results.aspx?k=**cr%c3%83%c2%a9er***";
var decoded = unescape(url); // or decodeURI(url);
for(var key in replacements)
    decoded = decoded.replace(key,replacements[key]);

使它更通用

if (jQuery.browser.msie) {
                retStr = encodeURI(retStr);
            }
