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>
