}js部分
data:{
navbarInitTop: 0, //导航栏初始化距顶部的距离
isFixedTop: false, //是否固定顶部
}
/*监听页面滑动事件*/
onPageScroll: function(e) {
let that = this;
let scrollTop = parseInt(e.scrollTop); //滚动条距离顶部高度
let isSatisfy = scrollTop >= that.data.navbarInitTop ? true : false;
//为了防止不停的setData, 这儿做了一个等式判断。 只有处于吸顶的临界值才会不相等
if (that.data.isFixedTop === isSatisfy) {
return false;
}
that.setData({
isFixedTop:isSatisfy
})
},
onShow: function () {
let that = this;
wx.createSelectorQuery().select('#operation-bar').boundingClientRect(function(rect) {
if (rect && rect.top > 0) {
var navbarInitTop = parseInt(rect.top);
that.setData({
navbarInitTop: navbarInitTop
});
console.log(that.data.navbarInitTop)
}
}).exec();
},wx.createSelectorQuery().select('#operation-bar').boundingClientRect(function(rect)}rect值可能为null
有查询节点需求可以用延时方法或者操作事件来获取。
