vue中watch数组或者对象
1、普通的watch data() { return { frontPoints: 0 } }, watch: { frontPoints(newValue, oldValue) { console.log(newValue) } } 2、数组的watch data() { return { winChips: new Array(11).fill(0) } }, watch: { winChips: { handler(newValue, oldValue) { for (let i = 0; i < newValue.length; i++) { if (oldValue[i] != newValue[i]) { console.log(newValue) } } }, deep: true } } 3、对象的watch data() { return { bet: { pokerState: 53, pokerHistory: 'local' } } }, watch: { bet: { handler(newValue, oldValue) { console.log
