mvc如何使用JavaScript在view和controller之间传递数据

在一般的BS项目开发中，我们经常需要在前台和后台之间传递数据，mvc架构中，也需要在view和controller之间传递数据，那么我们应该如何实现呢？

view想controller传递数据：view中代码

<li>@Html.ViewComponent().WfSaveLink(Model).Id("saveToLink").OnBeforeDo("externalData")</li>
<scriptlanguage="javascript" type="text/javascript">
        var externalData = function () {
            var state =$("#listItem").val();
            var explain =$("#TextArea1").val();
            if (CheckDataIsNotEmpty(state)&& CheckDataIsNotEmpty(explain)) {
                $.ajax({
                    type: "post",
                    url:"@Url.RouteUrl("workflowOperation", new { action ="UpdateModel", controller = "SignQuote" })",
                    data:
                {
                    state: state,
                    explain: explain,
                }
                });
            }
        };
    </script>

controller中代码：

Stringstate = QueryString["State"];
Stringexplain = QueryString["explain"];

controller想view中传递数据：

controller数据：

public ActionResultsendRead(string resourceID)
        {
            string msg = "数据测试";
            return Json(msg,JsonRequestBehavior.AllowGet);
        }

view中代码：

<scriptlanguage="javascript" type="text/javascript">
        var sendReadInfo = function () {
            $.ajax({
                type: "GET",
                url:"@Url.RouteUrl("workflowOperation", new { action ="sendRead", controller = "SignQuote" })" +"[email protected]",
                success: function (s) {
                    if (s) {
                        alert(s)
                        window.location =window.location;
                    }
                }
            });
        }
    </script>
