一，JS 代码参考

<script type="text/javascript">
function GetRequest() {
var url = location.search; //获取url中"?"符后的字串
var theRequest = new Object();
if (url.indexOf("?") != -1) {
var str = url.substr(1);
strs = str.split("&");
for (var i = 0; i < strs.length; i++) {
theRequest[strs[i].split("=")[0]] = unescape(strs[i].split("=")[1]);
}
}
return theRequest;
}
window.onload = function () {
$(".AdminBody").css("display", "none");

var strCookie = document.cookie;
// alert("strCookie=" + strCookie);
if (strCookie == "报表管理员")
{
$(".AdminBody").css("display", "block");
}
else
{
var Code = GetRequest()['code'];
if (Code) {
// alert("Code有值");

//if (strCookie != null && strCookie != "")
//{
// strCookie = strCookie.split('=')[1];
//}
if (!Code || strCookie) {
Code = strCookie;
}
$.ajax({
type: 'post',
url: "HandelServices/Login.ashx?Code=" + Code,
dataType: "json",
async: false,
success: function (data) {
// alert("Success");
console.log(data);
if (data != null && data != "") {
var result = JSON.parse(data);
var roleName = result[0].RoleName;
var Title = result[0].Title;
$("#HiddUser").val(Title);
document.cookie = roleName
//alert($("#HiddUser").val());
switch (roleName) {
case "报表管理员":
$(".AdminBody").css("display", "block");
break;
}
}
}, error: function () {
//alert("Error");
$(".AdminBody").css("display", "none");
}
});
} else {
// alert("Code无值");
window.location.href = 'https://open.work.weixin.qq.com/wwopen/sso/qrConnect?appid=wxf8d1544891f5d3a5&agentid=1000003&redirect_uri=http://wechatapps.smith-nephew.com.cn/salesreport/Admin.html&state=web_login@gyoss9';
}
}

}
</script>
