display flash and error message after ajax request Laravel
提问by Juan Carlo F. Yarra
After a successful ajax request, I want to send a flash message to my view (For example, upon editing, I'd like to redirect the user to the homepage with $flash = "Your shop has been update" ). Within the controller, it is easy but I don't know what to do within JavaScript. Do any of you know how to figure it out? Im using Laravel
在成功的 ajax 请求之后，我想向我的视图发送一条 flash 消息（例如，在编辑时，我想使用 $flash = "Your shop has been update" 将用户重定向到主页）。在控制器中，这很容易，但我不知道在 JavaScript 中该做什么。你们中有人知道如何弄清楚吗？我使用 Laravel

You can't redirect the within controller if you use ajax request.
如果使用 ajax 请求，则无法重定向内部控制器。
But you can do like this.
但是你可以这样做。
Send some parameters in the Controller like this
像这样在控制器中发送一些参数
$Response = array(
'success' => '1',
);
or
或者
$Response = array(
'success' => '0',
'error' => 'Your Flash Message'
);
and return it return $Response;
并归还 return $Response;
Then, In the ajax result you can redirect the user like this
然后，在 ajax 结果中，您可以像这样重定向用户
if (data.success == 1){
window.location = 'toyourdesiredpath';
}
else
{
//show your error message in your div or span
}

Just set a session flash message and a redirect url in Laravel controller (or return null if you want to reload the current page) like this:
只需在 Laravel 控制器中设置一个会话 flash 消息和一个重定向 URL（如果你想重新加载当前页面，则返回 null），如下所示：
if ($redirect) {
session()->flash('success', 'Your Flash Message for redirect');
return '/redirect-url';
} else {
session()->flash('success', 'Your Flash Message for reload');
return null;
}
And then make the redirect or reload inside the JavaScript code:
然后在 JavaScript 代码中进行重定向或重新加载：
$.post(`/ajax-url`, $(e.target).serialize()
).done((redirect) => {
if (redirect) {
window.location.href = redirect
} else {
window.location.reload()
}
}).fail((errors) => {
this.setState({
errors: errors.responseJSON.errors
})
})

You have to use redirect with message, try following example in your code :-
您必须对消息使用重定向，请在代码中尝试以下示例：-
return Redirect::to('user/login')->with('message', 'Login Failed');
return Redirect::to('user/login')->with('message', '登录失败');
