在我的项目中,我将Laravel 7.2与ui bootstrap / vue一起使用,并希望显示Chart.js中的图表。
我不想使用任何插件或模块,我更喜欢自己组织它。
我已尝试通过本文实现:https://www.chartjs.org/docs/latest/getting-started/integration.html
这是我的app.blade.php
<!doctype html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

<meta name="csrf-token" content="{{ csrf_token() }}">
<title>{{ config('app.name', 'Laravel') }}</title>
<!-- Scripts -->
<script src="{{ asset('js/app.js') }}" defer></script>

<body>
<div id="app">
@include('layouts.navbar')
<main class="py-4">
@yield('content')
</main>
</div>
</body>
</html>
这是我的观点
@extends('layouts.app')
@section('content')
@if (session('status'))
<div class="alert alert-success" role="alert">
{{ session('status') }}
</div>
@endif
<div class="container">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header">User online</div>
<div class="card-body">
@include('charts.useronline')
</div>
</div>
</div>
</div>
</div>
@endsection
这是局部视图
<canvas id="myChart" width="400" height="400"></canvas>
<script>
var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: ['Red', 'Blue', 'Yellow', 'Green', 'Purple', 'Orange'],
datasets: [{
label: '# of Votes',
data: [12, 19, 3, 5, 2, 3],
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',
'rgba(255, 206, 86, 0.2)',
'rgba(75, 192, 192, 0.2)',
'rgba(153, 102, 255, 0.2)',
'rgba(255, 159, 64, 0.2)'
],
borderColor: [
'rgba(255, 99, 132, 1)',
'rgba(54, 162, 235, 1)',
'rgba(255, 206, 86, 1)',
'rgba(75, 192, 192, 1)',
'rgba(153, 102, 255, 1)',
'rgba(255, 159, 64, 1)'
],
borderWidth: 1
}]
},
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero: true
}
}]
}
}
});
</script>
什么让我错了?任何的想法?我可能以错误的顺序实现了(我的意思是.js文件)?我找到了包含上面和下面的脚本的示例。
尝试在laravel html模板的“ views / layouts / app.blade.php”中删除应用布局中的defer
属性:
<script src="{{ asset('js/app.js') }}"></script>
