1.对应的xml里写上手势开始、滑动、结束的监听:
<view class="touch" bindtouchstart="touchStart" bindtouchmove="touchMove" bindtouchend="touchEnd" ></view>
2.js:
[javascript] view plain copy
var touchDot = 0;//触摸时的原点
var time = 0;// 时间记录,用于滑动时且时间小于1s则执行左右滑动
var interval = "";// 记录/清理时间记录
Page({
data: {...}
})
Page({
data: {
...
},
// 触摸开始事件
touchStart: function (e) {
touchDot = e.touches[0].pageX; // 获取触摸时的原点
// 使用js计时器记录时间
interval = setInterval(function () {
time++;
}, 100);
},
// 触摸移动事件
touchMove: function (e) {
var touchMove = e.touches[0].pageX;
console.log("touchMove:" + touchMove + " touchDot:" + touchDot + " diff:" + (touchMove - touchDot));
// 向左滑动
if (touchMove - touchDot <= -40 && time < 10) {
wx.switchTab({
url: '../左滑页面/左滑页面'
});
}
// 向右滑动
if (touchMove - touchDot >= 40 && time < 10) {
console.log('向右滑动');
wx.switchTab({
url: '../右滑页面/右滑页面'
});
}
},
// 触摸结束事件
touchEnd: function (e) {
clearInterval(interval); // 清除setInterval
time = 0;
},
