将URL中的UTF-8字符串转成中文字符串

包含utf-8的表单数据，

var form=$("#Form1");

var formData=form.serialize();

将formData作为url字符串，在前台js处理时，要把utf-8转换为中文，可调用如下函数：

//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 "";

str = str.toLowerCase();

nOffset = str.indexOf("%e");

if (nOffset == -1)

return str;

while (nOffset != -1) {

cstr += str.substr(0, nOffset);

str = str.substr(nOffset, str.length - nOffset);

if (str == "" || str.length < 9)

return cstr;

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

str = str.substr(9, str.length - 9);

nOffset = str.indexOf("%e");

}

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));

}
