在onLaunch里通过 wx.getSystemInfo({     success: function (res) {     var windowHeight = res.windowHeight;     console.log(windowHeight) // 566     } }) 在page中 wx.getSystemInfo({     success: function (res) {     var windowHeight = res.windowHeight;     console.log(windowHeight) // 572     } }) 这两个值不一致，是为什么呢？

<view  capture-catch:longpress='longpress'> <navigator open-type='navigate' url='/pages/plateform/userCenter/userCenter'>usernavigator>: 我同意！ view> 长按后会跳转。 测试后：capture-catch:tap可以阻止捕获，capture-catch:longpress无法阻止捕获
