url传中文，乱码，即便charset为 UTF-8，
$.ajax({ type: "POST", cache: false, url: "/ProductTypeAndCat/AddType?typeName=" + typeName, contentType: "application/x-www-form-urlencoded; charset=UTF-8", datatype: "JSON", });
data传中文，正确。
url: "/ProductTypeAndCat/AddType", data: {typeName:typeName}, success: function (data) { if (data.F == 0) { alert("添加陈功"); location.href = "/Admin/ProductType"; } else { alert(data.M); }, error: function (xhr, status, error) { alert(error); }
