没人回复我 我自己找到办法了，贴出来和大家共享
首先 要调用
var TimerMixin = require('react-timer-mixin');
然后写了个函数
getInitialState: function() {
return {
timer : null
};
},
componentDidMount: function() {
var time = this.props.expire ;
this._setTimer( time );
},
componentWillUnmount: function() {
clearInterval(this.state.timer) ;
},
_setTimer : function ( time ){
var _this=this;
var end_time = new Date(time).getTime(), //月份是实际月份-1
sys_second = (end_time - new Date().getTime()) / 1000,
timer;
this.setInterval(() => {
if (sys_second > 1) {
sys_second -= 1;
var day = Math.floor((sys_second / 3600) / 24);
var hour = Math.floor((sys_second / 3600) % 24);
var minute = Math.floor((sys_second / 60) % 60);
var second = Math.floor(sys_second % 60);
day = day < 10 ? "0" + day : day;
hour = hour < 10 ? "0" + hour : hour; //计算小时
minute = minute < 10 ? "0" + minute : minute; //计算分钟
second = second < 10 ? "0" + second : second; //计算秒杀
timer = day + ":" + hour + ":" + minute + ":" + second; //计算显示的时间
this.setState({ timer: timer });
} else {
clearInterval(timer);
}
}, 1000);
},
大家应该都能看懂
