关于移动端使用echarts点击图标外部不能关闭tooltip的问题

新建一个mixin文件  粘贴如下代码：

 1 /**
 2  * 1. 需要将echart实例赋值为  this.echartsInstance  `echartsInstance`  echarts 带s
 3  * 2. echarts所在的组件大小应该跟echarts图表实际大小相差不多
 4  * 3. 引入即可，无需编写其他代码
 5  */
 6  export const mixinAutoHideTooltip = {
 7     mounted() {
 8         this.mAutoHideTooltip(this.$el);
 9     },
10     data() {
11         this.mIsSelfTouch = false;
12         return {};
13     },
14     beforeDestroy() {
15         this.mRemoveListeners(this.$el);
16     },
17     methods: {
18         mAutoHideTooltip(dom) {
19             dom.addEventListener('touchstart', this.mHandleContainerTouchStart);
20             dom.addEventListener('touchend', this.mHandleContainerTouchEnd);
21             document.addEventListener('touchstart', this.mHandleDomcumentTouchStart);
22         },
23         mRemoveListeners(dom) {
24             dom.removeEventListener('touchstart', this.mHandleContainerTouchStart);
25             dom.removeEventListener('touchend', this.mHandleContainerTouchEnd);
26             document.removeEventListener('touchstart', this.mHandleDomcumentTouchStart);
27         },
28         mHandleContainerTouchStart() {
29             this.mIsSelfTouch = true;
30         },
31         mHandleContainerTouchEnd() {
32             this.mIsSelfTouch = false;
33         },
34         mHandleDomcumentTouchStart() {
35             if (this.mIsSelfTouch) return;
36             this.echartsInstance && this.mHideTooltip(this.echartsInstance);
37         },
38         mHideTooltip(echartsInstance) {
39             echartsInstance.dispatchAction({
40                 type: 'updateAxisPointer',
41                 currTrigger: 'mousemove',
42                 x: 0,
43                 y: 0
44             });
45         }
46     }
47 };

使用时如下：
