我正在使用jquery.scroll()触发隐藏和显示方法。当我滚动时,页面开始闪烁。我该怎么阻止。
我的js代码
var position = $('#page').scrollTop();
$(scrollable).scroll(function() {
// get the current position of scroll from #page
var scroll = $(scrollable).scrollTop();
console.log("position" , position);
console.log("scroll" , scroll)
// if initial position < current position we have not scroll down
if(scroll > position) {
$('.notification').hide();
} else {
$('.notification').show();
}
// set the initial position to current position of scroll
position = scroll;
});
我的HTML标记
<div id ="page">
<div class = "notification"></div>
<div id = "header"> </div>
</div>
我的CSS
.page{
position: relative;
z-index: 10;
height: 100%;
}
.notification{
position: sticky
}
.header{
position:fixed
}
答案 0 :(得分:1)
有一个失踪者;并且未定义可滚动,但似乎没有闪烁。也许这是代码中的其他内容。我已经在下面测试过了。
example = pd.DataFrame(example)
example['base_date'] = pd.to_datetime(example['base_date'].astype(str), format='%d%m%Y')
example['base_date'] = example['base_date'].dt.date
example['date_2'] = pd.to_datetime(example['date_2'].astype(str), format='%d%m%Y')
example['date_2'] = example['date_2'].dt.date
for(var i = 0; i < 20; i++){
$("#content").append("SOME INFO </br>");
}
var scrollable = $("#content");
var position = $('#page').scrollTop();
$(scrollable).scroll(function() {
// get the current position of scroll from #page
var scroll = $(scrollable).scrollTop();
console.log("position" , position);
console.log("scroll" , scroll);
// if initial position < current position we have not scroll down
if(scroll > position) {
$('.notification').hide();
} else {
$('.notification').show();
}
// set the initial position to current position of scroll
position = scroll;
});
.page{
position: relative;
z-index: 10;
height: 100%;
}
.notification{
position: sticky;
background: red;
color: red;
}
.header{
position:fixed;
}
#content{
height: 100px;
overflow: auto;
background: #CCC;
}
