使用谷歌图表加载 gif 和动画

Question

I'm creating a dashboard using Google Charts and I need a way to include a loading gif or text that reads "Loading.." while my div or canvas loads with the chart. Also, I'm having a hard time figuring out how to get the charts to animate on start up as well as when values are updated.

Answer 1

A quick google search for 'loading gif' bought up a few results..

Answer 2

Ok I figured it out. It was literally 1 line of code. I wanted to do it with raw javascript and css. Its just a matter of grabbing the element and changing or 'setting' the class.

document.getElementById("myDiv").className = "stop_loading";
