ajax中get提交的时候改变参数的编码

function transUrlParaCode(para){
var s = para;
if (para != null){
s = para.replaceAll("%", "%25");
s = s.replaceAll(" ", "%20");
s = s.replaceAll("/", "%2F");
s = s.replaceAll("#", "%23");
s = s.replaceAll("\\+", "%2B");
s = s.replaceAll("\\?", "%3F");
s = s.replaceAll("&", "%26");
s = s.replaceAll("\\=", "%3D");
}
return s;
}

function jqTrans(str){
if(str.length>0&&str.trim()!=""){
str=str.replaceAll(" ","");
str=str.replaceAll("#","");
str=str.replaceAll("\\$","");
str=str.replaceAll("=","");
str=str.replaceAll("&","");
str=str.replaceAll("@","");
}
return str;
}
