1、wxml代码
<!--index.wxml--> <view class="container"> <button type=\'primary\' style=\'margin-bottom:40px;\' bindtap=\'startSetInter\'>开始</button> <button type=\'primary\' bindtap=\'endSetInter\'>结束</button> </view>
2、js代码
将计时器赋值给 data 中的变量，这样在任何方法中都可以清除计时器
Page({
data: {
//存储计时器
setInter:\'\',
num:1,
},
onLoad: function () {
var that = this;
},
startSetInter: function(){
var that = this;
//将计时器赋值给setInter
that.data.setInter = setInterval(
function () {
var numVal = that.data.num + 1;
that.setData({ num: numVal });
console.log(\'setInterval==\' + that.data.num);
}
, 2000);
},
endSetInter: function(){
var that = this;
//清除计时器 即清除setInter
clearInterval(that.data.setInter)
},
onHide: function () {
},
onUnload: function () {
var that =this;
//清除计时器 即清除setInter
clearInterval(that.data.setInter)
},
})
