echarts-JSON请求数据

1、问题背景

将数据封装在JSON文件中，利用get方法请求数据

2、实现源码

<!DOCTYPE html><html> <head>  <meta charset="UTF-8">  <title>echarts-JSON请求数据</title>  <link rel="shortcut icon" href="../js/echarts-2.2.7/doc/asset/ico/favicon.png">  <script type="text/javascript" src="../js/echarts-2.2.7/doc/asset/js/jquery.min.js" ></script>  <script type="text/javascript" src="../js/echarts.js" ></script>  <script>   $(document).ready(function(){    var chart = document.getElementById('chart');    var chartData = echarts.init(chart);        chartData.setOption({           title: {               text: '异步数据加载示例'           },           tooltip: {},           legend: {               data:['销量']           },           xAxis: {               data: []           },           yAxis: {},           series: [{               name: '销量',               type: 'bar',               data: []           }]       });           $.get('../js/data.json').done(function (data) {          console.dir(data);     // 填入数据        chartData.setOption({            xAxis: {                data: data.categories            },            series: [{                name: '销量',                data: data.data            }]        });        });        function eConsole(param)                 {                    console.dir(param);                }        chartData.on("click",eConsole);   });  </script> </head> <body>  <div id="chart" style="width: 1900px; height: 900px;"></div> </body></html>

data.json:

{ "categories": [  "苹果",  "橘子",  "荔枝",  "桃子",  "栗子",  "梨子",  "柿子" ], "data": [  500,  280,  386,  190,  107,  207,  452 ]}
