javascript - Ajax.BeginForm 中的两个提交按钮。需要在OnSuccess中调用不同的js函数

Question

我的 MVC 页面上有一个 Ajax 表单，带有两个单独的提交按钮...

@using (Ajax.BeginForm("Save", "Company", new AjaxOptions() {
    HttpMethod="Post", OnSuccess="closeForm" 
}, new {@id = "companyEditForm"})) {
    ....some edit fields......

    <input type="submit" value="Save & Next"/>
    <input type="submit" value="Save" />
}

我想在使用“保存并下一步”按钮提交表单后调用不同的 js 函数。因此，如果用户单击“保存”按钮，则应提交表单，然后调用“closeForm”javascript 函数。如果用户单击“保存并下一步”按钮，则应提交表单，然后调用“nextForm”javascript 函数。有实现此目的的简单方法吗？

Answer 1

Is there a simple way of achieving this?

不，但是您可以让 Controller 操作传递在结果中单击的按钮。这可以作为 Json 属性(如果您返回 JSON)来完成，也可以是自定义响应 HTTP header 。

然后在您的成功回调(只能是一个)中，您可以检索此值以了解单击了哪个按钮并采取相应行动。

因此，首先为您的提交按钮命名，以便您知道点击了哪个按钮:

@using (Ajax.BeginForm("Save", "Company", new AjaxOptions() {
    HttpMethod="Post", OnSuccess="onSuccess" 
}, new { id = "companyEditForm" })) {
    ....some edit fields......

    <button type="submit" name="btn" value="save_next">Save &amp; Next</button>
    <button type="submit" name="btn" value="save">Save</button>
}

然后在你的 Controller Action 中

[HttpPost]
public ActionResult Save(MyViewModel model)
{
    Response.AppendHeader("X-Button", Request["btn"]);

    ... your usual processing
}

最后在您的 onSucecss 回调中:

function onSuccess(data, status, xhr) {
    function onSuccess(data, status, xhr) {
        var btn = xhr.getResponseHeader('X-Button');
        if (btn == 'save_next') {
            // The "Save & Next" button was clicked
        } else if (btn == 'save') {
            // The "Save" button was clicked
        } else {
            // The user didn't submit the form by using the mouse and
            // clicking on a button, he simply pressed Enter while 
            // inside some text field or you have some other portion of
            // javascript which triggered the form submission without pressing
            // on any submit button
        }
    }
}
