ajax与json

浏览数：31 / 时间：2015年06月09日

使用以下方法必须注意路径是否正确，这点是绝大部分问题的根源。

取数例子：不刷新获取登录信息

登录前：

登录后：

页面jq：

        $("#btnLogin").click(function () {
            var name = $("#loginName");
            var pass = $("#loginPass");
            var code = $("#txtCode");

            if ($.trim(name.val()) == "") { name.focus(); return alert("请输入你的用户名！"); }
            if ($.trim(pass.val()) == "") { pass.focus(); return alert("请输入你的密码！"); }
            if ($.trim(code.val()) == "") { code.focus(); return alert("请输入你的验证码！"); }

            $.ajax({
                contentType: "application/json",
                url: "/WS/vinson.asmx/Logon",
                data: "{userName:‘" + name.val() + "‘,userPass:‘" + pass.val() + "‘,code:‘" + code.val() + "‘}",
                type: "POST",
                dataType: "json",
                success: function (json) {
                    json = eval("(" + json.d + ")");

                    if (json.success == "error") {
                        $("#divLogin").show();

                        alert(json.msg);
                        code.val("");
                        pass.val("");
                        pass.focus();
                        UpdateImage();
                    } else if (json.success == "success") {
                        $("#imgFace").attr("src", "/gamepic/face" + json.fid + ".gif");

                        $("#dlInfo").html("<span>帐号：" + name + "</span><span>ＩＤ：" + json.gid + "</span>").attr("title", json.account);
                        $("#mOrder").html(json.morder);
                        $("#loves").html(json.loves);
                        $("#mPat a").before(json.UserPat+" ");
                        $("#counts").html(json.counts);
                        if (parseInt(json.dayCount) > 0)
                            $("#qd ul").css("background", "url(../images/qiandao_n.png) 0 0px no-repeat");

可以使用这种方法跳到asmx页面做一些事情，而不仅仅是像上面那样取数：
