Php Symfony2和Submit-wit-JavaScript：如何获取html内容
我有一个在Symfony2项目的表格，我需要提交表格。第一个想法是使用ajax提交，但问题是这将无法通过symfony2所需的验证，我收到了CSRF错误消息（请参阅我前面的问题：） 感谢@Elnur的回答，我现在可以使用$post提交表格，但还有一个问题 使用Ajay，我将返回一个html响应，并且我能够将此响应附加到一个html元素：Php Symfony2和Submit-wit-JavaScript：如何获取html内容,php,javascript,json,post,symfony,Php,Javascript,Json,Post,Symfony,我有一个在Symfony2项目的表格，我需要提交表格。第一个想法是使用ajax提交，但问题是这将无法通过symfony2所需的验证，我收到了CSRF错误消息（请参阅我前面的问题：） 感谢@Elnur的回答，我现在可以使用$post提交表格，但还有一个问题 使用Ajay，我将返回一个html响应，并且我能够将此响应附加到一个html元素： $.ajax({ type: "POST", async: true, url: href, cache: false,

您的问题是返回的是全新的HTML内容。
您只需要返回您的JS能够理解并以您想要的方式处理的信息
use Symfony\Component\HttpFoundation\Response;
if ($valid) {
$data = array(
'success' => true,
'responseCode' => 307, /* Redirect Temp */
'redirectURI' => $this->generateUrl('SciForumVersion2Bundle_user_submission', array("key"=>$submission->getHashKey())),
'message' => '<h3>You\'re about to be redirected...</h3>'
);
} else {
$data = array(
'success' => false,
'responseCode' => 400, /* Bad Request */
'message' => '<h3 class="error">Cannot send form<br>* Field NAME is empty</h3>'
);
}
$json = json_encode($data);
/* Response($data,$statusCode,$additionnalHeaders) */
return new Response($json,200,array('Content-Type'=>'application/json'));
你能给我们看看你的控制器吗？@Touki，谢谢。我将在一分钟内更新我的问题。您的AJAX请求需要返回。Symfony正在尝试重定向用户。不能从AJAX请求重定向。如果你想显示内容，就这样做<代码>$（“#content.contentwrap.itemwrap”）.html（data.content）是。这将用Symfony重定向填充你的“.itemwrap”。让我们来回答这个问题，并提供极好的帮助，一个真正的专业人士。非常感谢你。
