you may have an infinite update loop in watcher with expression
echarts中option的data传数组,千万不要对数组进行操做. 不然会出bug you may have an infinite update loop in watcher with expression 在带有表达式的观察程序中，可能有无限更新循环 为何会出现这个bug呢? 分析以下: 错误的模式下:首先yKeyData在created生命周期中获取数据时也发生了变化,watch监听到后,就执行option操做,结果option中的data中的数组进行倒置了,那么watch监听的yKeyData又发生变化,陷入了无限死循环中. 前端
正确的模式下:data就是个纯数组 vue
总结:请不要在watch中改变所监听的数据.git
