1、错误描述

echarts.js:1136 Uncaught Error: Initialize failed: invalid dom.

2、错误原因

<!DOCTYPE html><html> <head>  <meta charset="UTF-8">  <title></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>   var myChart2 = echarts.init(document.getElementById('main2'));      myChart2.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       myChart2.setOption({           xAxis: {               data: data.categories           },           series: [{               // 根据名字对应到相应的系列               name: '销量',               data: data.data           }]       });      });  </script> </head> <body>  <div id="chart" style="width: 1200px; height: 560px;"></div> </body></html>

{ "categories": [  "衬衫",  "羊毛衫",  "雪纺衫",  "裤子",  "高跟鞋",  "袜子" ], "data": [  5,  20,  36,  10,  10,  20 ]}

echarts在用json数据请求时未调用

3、解决办法

（1）将上述代码放在一个函数中，然后在onload中调用这个函数

（2）用jQuery方法

<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>
