you may have an infinite update loop in watcher with expression
echarts中option的data傳數組,千萬不要對數組進行操做. 不然會出bug you may have an infinite update loop in watcher with expression 在帶有表達式的觀察程序中，可能有無限更新循環 爲何會出現這個bug呢? 分析以下: 錯誤的模式下:首先yKeyData在created生命週期中獲取數據時也發生了變化,watch監聽到後,就執行option操做,結果option中的data中的數組進行倒置了,那麼watch監聽的yKeyData又發生變化,陷入了無限死循環中. 前端
正確的模式下:data就是個純數組 vue
總結:請不要在watch中改變所監聽的數據.git
