wx.createSelectorQuery().select(‘#box‘).boundingClientRect(function (rect) { width = rect.width height = rect.height top = rect.top }).exec()
如上,拿到了id为box的view,并获取到了它的宽、高等属性,此段代码要放在onReady函数中
注意:如果这个view的宽高是随着内容而变化的话,这样获取到的宽高就有可能还是渲染完成前的值,不知是不是小程序自己的bug,解决方案是在获取外加一个定时器,如下
setTimeout(() => { let _this = this wx.createSelectorQuery().select(‘#container-title‘).boundingClientRect(function (rect) { width = rect.width height = rect.height top = rect.top }).exec() },300)
