JS将URL中的UTF-8字符串转成中文字符

//将URL中的UTF-8字符串转成中文字符串
function getCharFromUtf8(str) {
var cstr = "";
var nOffset = 0;
if (str == "")
return "";

cstr += utf8ToChar(str.substr(0, 9));

}
return cstr + str;
}

//将编码转换成字符
function utf8ToChar(str) {
var iCode, iCode1, iCode2;
iCode = parseInt("0x" + str.substr(1, 2));
iCode1 = parseInt("0x" + str.substr(4, 2));
iCode2 = parseInt("0x" + str.substr(7, 2));
return String.fromCharCode(((iCode & 0x0F) << 12) | ((iCode1 & 0x3F) << 6) | (iCode2 & 0x3F));
}

//获取当前页面的URL

var url = location.href;

//截取传递参数
var paraString = url.substring(url.indexOf("=") + 1, url.length);
