ajax请求成功后,我想向我的视图发送一条flash消息(例如,编辑后,我想使用$flash=“Your shop has 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中做什么。你们有谁知道怎么弄清楚吗?我在用拉威尔
控制器
public function postUpdate (Request $request)
{
$this->validate($request, [
'website_name' => 'required',
'website_url' => 'required',
'category' => 'required',
'type' => 'required',
'sells' => 'required',
'location' => 'required',
'description' => 'required',
'payment' => 'required'
]);
Shop::where('username', '=', Auth::user()->username)->update(['website_name' => Input::get('website_name'),
'website_url' => Input::get('website_url'), 'type' => Input::get('type'), 'category' => Input::get('category'), 'sells' => Input::get('sells'), 'location' => Input::get('location'),
'payment' => Input::get('payment'), 'description' => Input::get('description')]);
return Response::json(['message' => 'Success', 'message_class' => 'alert alert-success fade in']);
}
AJAX
$(".update-form").submit(function(s){
s.preventDefault();
var website_name = $('input[name=website_name]').val();
var website_url = $('input[name=website_url]').val();
var type = $('#type option:selected').val();
var category = $('#category option:selected').val();
var sells = $('input[name=sells]').val();
var location = $('input[name=location]').val();
var payment = $('input[name=payment]').val();
var description = $("textarea#message").val();
$.ajax({
type: "POST",
url: "advertiser/update",
data: {
_token: token, website_name: website_name, website_url: website_url, type: type, category: category, sells: sells, location: location, payment: payment, description: description
},
success: function() {
$('.modal-backdrop').remove();
$('body').load('advertiser')
},
error: function(data) {
$('body').load('advertiser')
}
})
});
超文本标记语言
<div class="row" id="errors">
@if (Session::has('message'))
<div class="{!! Session::get('message_class') !!}">
<a href="#" class="close" data-dismiss="alert">×</a>
<strong>Note!</strong> {!! Session::get('message') !!}
</div>
@endif
@if($errors->has())
<div class="alert alert-danger fade in">
<a href="#" class="close" data-dismiss="alert">×</a>
<p>the following errors have occured:</p>
<ul>
@foreach($errors->all() as $error)
<li>{{$error}}</li>
@endforeach
</ul>
</div>
@endif
如果使用ajax请求,则无法重定向内部控制器。
但你可以这样做。
像这样在控制器中发送一些参数
$Response = array(
'success' => '1',
);
或
$Response = array(
'success' => '0',
'error' => 'Your Flash Message'
);
并返回return$Response代码>
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
}
只需在Laravel controller中设置会话闪存消息和重定向url(如果要重新加载当前页面,请返回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;
}
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
})
})
您必须对消息使用重定向,请在代码中尝试以下示例:-
返回重定向::到(用户/登录)-
