Echarts cannot get the value of the attribute "getAttribute": the object is null or undefined. Solution: echarts

When using Baidu's echarts, when running in IE9, sometimes errors such as the question are reported, and sometimes refreshed and normal. The cause of this error is:

The echarts. js reference is placed in the head or in front of the HTML code in the body, causing blocking of the html behind the loading.

The solution is to put the echarts. js reference before </body>, which is a perfect solution!
