无刷新提交表单(非Ajax实现)

HTML代码:

<iframe id="fra" name="frm" style="display: none;"></iframe>

<form id="frm" method="post" action="@Url.Content("~/Backstage/MachineMng/RoadSet/SaveTrackRoad")?roadId[email protected]" target="frm">

    这里是表单内容

</form>
View Code

JS代码:

若保存成功,后台返回{"ok":true};若保存失败,后台返回{"ok":false, "msg":"错误信息"}

function save() {

    $("#frm").submit();

    $("#fra").one("load", function () {

        var data = eval("(" + $("#fra").contents().find("body").html() + ")");

        if (data.ok) {

            $("#divtrackroad").load("TrackRoad?roadId=" + '@ViewBag.roadId' + "&roadName=" + '@ViewBag.roadName' + "&viewOrEdit=1&t=" + new Date().valueOf());

        } else {

            alert("保存失败:" + data.msg);

        }

    });

}
