实现Server.UrlEncode和Server.UrlDecode功能的js代码

<script>
var EncodeURI = function(unzipStr,isCusEncode){
    if(isCusEncode){
        var zipArray = new Array();
        var zipstr = "";
        var lens = new Array();
        for(var i=0;i<unzipStr.length;i++){
         var ac = unzipStr.charCodeAt(i);
         zipstr += ac;
         lens = lens.concat(ac.toString().length);
        }
        zipArray = zipArray.concat(zipstr);
        zipArray = zipArray.concat(lens.join("O"));
        return zipArray.join("N");
    }else{
        //return encodeURI(unzipStr);
        var zipstr="";
        var strSpecial="!\"#$%&'()*+,/:;<=>?[]^`{|}~%";
        var tt= "";

        for(var i=0;i<unzipStr.length;i++){
            var chr = unzipStr.charAt(i);
            var c=StringToAscii(chr);
            tt += chr+":"+c+"n";
            if(parseInt("0x"+c) > 0x7f){
                 zipstr+=encodeURI(unzipStr.substr(i,1));
            }else{
                 if(chr==" ")
                    zipstr+="+";
                 else if(strSpecial.indexOf(chr)!=-1)
                    zipstr+="%"+c.toString(16);
                 else
                    zipstr+=chr;
                }
            }
        return zipstr;
    }
}

var DecodeURI = function(zipStr,isCusEncode){
    if(isCusEncode){
        var zipArray = zipStr.split("N");
        var zipSrcStr = zipArray[0];
        var zipLens;
        if(zipArray[1]){
            zipLens = zipArray[1].split("O");   
        }else{
            zipLens.length = 0;
        }
       
        var uzipStr = "";
       
        for(var j=0;j<zipLens.length;j++){
            var charLen = parseInt(zipLens[j]);
            uzipStr+= String.fromCharCode(zipSrcStr.substr(0,charLen));
            zipSrcStr = zipSrcStr.slice(charLen,zipSrcStr.length);
        }       
        return uzipStr;
    }else{
        //return decodeURI(zipStr);
        var uzipStr="";

        for(var i=0;i<zipStr.length;i++){
            var chr = zipStr.charAt(i);
            if(chr == "+"){
                 uzipStr+=" ";
            }else if(chr=="%"){
                 var asc = zipStr.substring(i+1,i+3);
                 if(parseInt("0x"+asc)>0x7f){
                     uzipStr+=decodeURI("%"+asc.toString()+zipStr.substring(i+3,i+9).toString()); ;
                     i+=8;
                 }else{
                     uzipStr+=AsciiToString(parseInt("0x"+asc));
                     i+=2;
                 }
            }else{
                 uzipStr+= chr;
            }
        }
        return uzipStr;
    }
}

var StringToAscii = function(str){
    return str.charCodeAt(0).toString(16);
}

var AsciiToString = function(asccode){
    return String.fromCharCode(asccode);
}
</script>

以上代码跟c#写的Server.UrlEncode实现的效果是一样的，如果大家需要在客户端传入中文的字符，可以试试这个函数。

使用方法："http://www.fanchuanbook.com/search.aspx?q=" + EncodeURI(q,false)

<script>

var url="{PHPCMS_PATH}yczx/searchcy.php?ordertype=1&search=1&searchtype=content&catid=183&keywords="+EncodeURI("{$title}");
var encode=EncodeURI("{$title}");
document.write('<a href=\"' + url +'\" target=\"_blank\" class=\"wg-x12\">');
document.write('点击可查看该场所所有演出排期</a>');
</script>
