Table.vue 中的 loads 函数，每次执行时 counts() 函数更新 ac 变量的值，并定义触发 exchange 事件。
loads(){ this.$axios.get('/all').then(resp =>{ if( resp){ this.tableData = resp.data this.counts() this.$emit('exchange') } }) },FileMon.vue 监听 exchange 事件，触发时执行 exchange 函数
<el-container> <el-aside> <Echart ref="ac_e"></Echart> </el-aside> <el-container> <el-main> <Table ref="ac_t" @exchange="exchange()"></Table> </el-main> </el-container> </el-container>exchange 函数 取 Echart.vue 中的 ac 变量 赋值为 Table.vue 中的 ac 变量，调用 Echart.vue 变量的 load 方法。
