[英]JavaScript Error - Uncaught SyntaxError: Unexpected token {
I am trying to use Chart JS in one of my laravel applications. 我试图在我的laravel应用程序之一中使用Chart JS。
I am pushing the data through the route and using json_encode($gross) to echo the gross of each order by day but I am getting the following error in my console log: 我通过路由推送数据,并使用json_encode($ gross)逐日回显每个订单的毛额,但是在控制台日志中出现以下错误:
Uncaught SyntaxError: Unexpected token { 未捕获到的SyntaxError:意外令牌{
It references the the line of where I have used json_encode($gross). 它引用了我使用json_encode($ gross)的行。 Anyone have any ideas why this is happening? 任何人都知道为什么会这样吗?
Here is the code coming through the controller:
public function index()
{ $wkRevenue = \App\Order::where('created_at', '>=' , \Carbon\Carbon::now()->startOfMonth())->get();
// dd($wkRevenue->pluck('created_at','gross'));
return view('admin.dashboard')
->with('created_at', $wkRevenue->pluck('created_at'))
->with('grosss', $wkRevenue->pluck('gross'));
}
Here is the code in the js file:
var data = {
type:'line',
labels:['Mon','Tues','Wed','Thurs','Fri','Sat','Sun'],
datasets:[
{
data: {!! json_encode($gross) !!},
backgroundColor:'rgba(137, 200, 85, 0.4)',
}
]
}
var graph = document.getElementById('myNewChart').getContext('2d');
var myNewChart = new Chart(graph ,{
type: "line",
data: data,
options:{
title:{
display:true,
}
}
});
You have a typo in your controller: 您的控制器中有错字:
->with('grosss', $wkRevenue->pluck('gross'));
needs to be: 需要是:
->with('gross', $wkRevenue->pluck('gross'));
Laravel changed the pluck()
method in 5.2 to return a collection instead of an array. Laravel在5.2中更改了 pluck pluck()
方法以返回集合而不是数组。
In your view change your json_encode()
to: 在您的视图中,将json_encode()
更改为:
{!! $gross->toJson() !!}
