列表内容出现倒计时
从后台接口获取数据
getGameList() {
api.getList().then(data => {
if (data) {
this.gameDataList = data.resultData;
for (let i = 0; i < this.gameDataList.length; i++) {
this.gameDataList[i].surplus = this.gameDataList[i].endTime - new Date().getTime(); //给列表加属性,剩余时间字段
}
this.total = data.totalRecord;
this.beginTimer(); //启动计时器减指定字段的时间
}
})
},
2.运用定时器实时减去时间
//定时器
beginTimer() {
if (this.timer != null) {
clearInterval(this.timer);
}
this.timer = setInterval(() => {
for (let i = 0, len = this.gameDataList.length; i < len; i++) {
const item = this.gameDataList[i];
if (item.surplus > 0) {
item.surplus = Math.abs(item.surplus - 1000);
this.$set(item, 'surplus', item.surplus);
}
};
this.$forceUpdate(); //这句很重要,要不列表不刷新
}, 1000);
},
