新手关于echarts异步调用问题请教。

Question

我异步处理这个数据并显示出来，把data0的数据放到文件abc.json.这个怎么处理，还有调用异步的时候是带name:'MA5'这些放异步里面吗？还是可以先加载。异步只要填入数据就可以了。自己整了很久没解决。只能提问了。另外代码可以放在XXX.JS里面吗？
我放在XXX.JS里面用加载的时候，第一句varmyChart=echarts.init(document.getElementById('main'),'light');就报错是为什么。
恳请批点。非常感谢

Answer 1

varmyChart=echarts.init(document.getElementById('main'),'light');报错一般是因为在页面上没有找到id='main'的元素。异步调用的时候，可以这样操作：varresult=[];varoption={...,series:[{...,data:result}]};asyncres.get(function(data){result=data;myChart.setOption(option,true);});先声明一个空数组varresult=[]，在option中直接给series写上data:result。待异步调用结束时，给result赋值，然后再次执行myChart.setOption(option,true);
