“return json（true，jsonrequestbehavior.allowget）"在屏幕上返回'true'而不是调用onsuccess方法 [英] "return json(true,jsonrequestbehavior.allowget)" returns 'true' on screen instead of calling onsuccess method

问题描述

"return Json(true,JsonRequestBehavior.AllowGet)" returns 'true' on screen instead of calling Onsuccess Method

我从Ajax.BeginForm调用Action方法（ActionMethod，新的AjaxOptions {OnSuccess =MyScript，HTTPMethod =POST，OnFailure =MyScript2}）



我尝试过：



我尝试将Json作为真正的首先它没有工作，所以我尝试返回bool变量本身。唉!它没有。

I am calling Action method from Ajax.BeginForm("ActionMethod",new AjaxOptions{OnSuccess="MyScript",HTTPMethod="POST",OnFailure="MyScript2"})

What I have tried:

I tried returning Json as true first it didnt work so i tried returning the bool variable itself. Alas! it didnt.

推荐答案

按照以下步骤在MVC中实现AJAX.BeginForm



Step1 ：在web.config中启用Unobustrive

Follow below steps to implement AJAX.BeginForm in MVC

Step1: Enable Unobustrive in web.config

<appsettings>
    <add key="ClientValidationEnabled" value="true" />
    <add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appsettings>

Step2 ：在视图页面中添加以下代码（* .cshtml）

Step2: Add following code in your view page(*.cshtml)

@using (Ajax.BeginForm("PerformAction", new AjaxOptions { OnSuccess = "OnSuccess", HttpMethod="POST", OnFailure = "OnFailure" }))
{
    <fieldset>
        <input type="submit" value="Submit" />
    </fieldset>
}

<script src="~/Scripts/jquery.unobtrusive-ajax.min.js"></script>
<script type="text/javascript">

    function OnSuccess(response) {
        alert(response);
    }

    function OnFailure(response) {
        alert("Something wrong happens. Error is: " + response);
    }

</script>

Step3 ：添加在Controller的动作中跟随代码

[HttpPost]
public JsonResult performAction()
{
	return Json(true, JsonRequestBehavior.AllowGet);
}
