MVC按钮单击调用POST Action方法

如何从按钮点击事件中调用具有复杂参数的MVC操作方法,如下所示?

[ValidateInput(false)]
[HttpPost]
public ActionResult Export(ViewModel vm)
{
  // some logic
}

我已将其设为POST操作,因为我需要将按钮所在的当前页面的HTML标记传递给操作方法太长。我试过这个,但这是一个GET操作

<input type="button" value="Detail" onclick="location.href='@Url.Action("Export", "Report")?html=' + $('#test').html()" />

如果您想使用按钮单击执行此操作,您可以订阅JS中按钮的单击事件。在你的JS中,你可以做一个ajax帖子,它会将JSON对象(你的VM)发布到你的行动中:

剃刀:

<input type="button" value="Detail" id="buttonId" />

JS:

    $('#buttonId').click(function () { //On click of your button

    var property1 = $('#property1Id').val(); //Get the values from the page you want to post
    var property2 = $('#property2Id').val();


    var JSONObject = { // Create JSON object to pass through AJAX
Property1: property1, //Make sure these names match the properties in VM
Property2: property2
};

    $.ajax({ //Do an ajax post to the controller
        type: 'POST',
        url: './Controller/Action',
        data: JSON.stringify(JSONObject),
        contentType: "application/json; charset=utf-8",
        dataType: "json"
        });

另一种方法是使用表单提交视图模型。

    @using (Html.BeginForm("ActionName", "ControllerName", FormMethod.Post)) 
{
    @Html.AntiForgeryToken()

<div class="form-horizontal">

    @Html.ValidationSummary(true, "", new { @class = "text-danger" })

    <div class="form-group">
        @Html.LabelFor(model => model.PropertyName1, htmlAttributes: new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            <input type="text" id="PropertyName1" name="PropertyName1" class="form-control"  />
            @Html.ValidationMessageFor(model => model.PropertyName1, "", new { @class = "text-danger" })
        </div>
    </div>

    <div class="form-group">
        @Html.LabelFor(model => model.PropertyName2, htmlAttributes: new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.EditorFor(model => model.PropertyName2, new { htmlAttributes = new { @class = "form-control" } })
            @Html.ValidationMessageFor(model => model.PropertyName2, "", new { @class = "text-danger" })
        </div>
    </div>



    <div class="form-group">
        <div class="col-md-offset-2 col-md-10">
            <input type="submit" value="Button text" class="btn btn-primary" />
        </div>
    </div>
    </div>
}

您可以使用HTML表单

执行此操作
<form action="@Url.Action("Export", "Report")" method="POST">
    <input type="hidden" name="html" value="ADD YOUR HTML HERE">
    <input type="button" value="Detail" />
</form>

在控制器内部,您需要使用html参数

[ValidateInput(false)]
[HttpPost]
public ActionResult Export(ViewModel vm, string html)
{
    // some logic
}

试试这个

<form action="@Url.Action("Export", "Report")" method="POST">
<input type="hidden" name="html" id="html"  value="ADD YOUR HTML HERE">
<input type="button" id="btn1" value="Detail" />
</form>

在js中添加脚本

$("#btn1").click(function(){
   $("#html").val($('#test').html());
})

在方法 string html

中添加param
