如何让固定的“粘性” div 留在视口之外
我正在尝试遵循本教程: http://jqueryfordesigners.com/fixed-floating-elements/< /a>.
问题是,每当将固定定位应用于 div 时,如果浏览器宽度发生更改,则 div 会水平移动以适合视口内。在教程示例中 http://static.jqueryfordesigners.com/demo/fixedfloat.html这不会发生。
这是我的代码(所有内容都在相对定位的#wrapper 中):
CSS:
#cart {
position: absolute;
right: 0;
width: 270px;
}
#target {
width: 270px;
height: 200px;
background-color: blue;
background-position: 50% 50%;
background-repeat: no-repeat;
position: absolute;
top: 250px;
right: 0;
padding: 0;
border-radius: 15px 15px 0 0 ;
}
#drag-here {
width: 270px;
height: 0;
background-image: url(drag-here.png);
background-repeat: no-repeat;
display: none;
position: absolute;
top: 470px;
right: 0;
}
#cart-list {
display: none;
position: absolute;
top: 430px;
right: 0;
list-style-type: none;
}
.sticky #target {position: fixed; top: 5px;}
.sticky #drag-here {position: fixed; top: 225px;}
.sticky #cart-list {position: fixed; top: 185px;}
HTML:
<section id="cart">
<div id="target" class="target-listen"></div>
<div id="drag-here"></div>
<ul id="cart-list">
</ul>
</section>
JQuery:
sticky = false;
initialOffset = $("#target").offset().top - 5;
$(window).scroll(function () {
if ($(this).scrollTop() >= initialOffset) {
if (!sticky) {
$("#cart").addClass("sticky");
sticky = true;
}
}
else {
if (sticky) {
$("#cart").removeClass("sticky");
sticky = false;
}
}
});

I'm trying to follow this tutorial: http://jqueryfordesigners.com/fixed-floating-elements/.
The problem is that whenever the fixed positioning is applied to the div, if the browser width gets changed the div moves horizontally to fit inside the viewport. In the tutorial example http://static.jqueryfordesigners.com/demo/fixedfloat.html this does not happen.
This is my code (everything is inside a relative-positioned #wrapper):
CSS:
#cart {
position: absolute;
right: 0;
width: 270px;
}
#target {
width: 270px;
height: 200px;
background-color: blue;
background-position: 50% 50%;
background-repeat: no-repeat;
position: absolute;
top: 250px;
right: 0;
padding: 0;
border-radius: 15px 15px 0 0 ;
}
#drag-here {
width: 270px;
height: 0;
background-image: url(drag-here.png);
background-repeat: no-repeat;
display: none;
position: absolute;
top: 470px;
right: 0;
}
#cart-list {
display: none;
position: absolute;
top: 430px;
right: 0;
list-style-type: none;
}
.sticky #target {position: fixed; top: 5px;}
.sticky #drag-here {position: fixed; top: 225px;}
.sticky #cart-list {position: fixed; top: 185px;}
HTML:
<section id="cart">
<div id="target" class="target-listen"></div>
<div id="drag-here"></div>
<ul id="cart-list">
</ul>
</section>
JQuery:
sticky = false;
initialOffset = $("#target").offset().top - 5;
$(window).scroll(function () {
if ($(this).scrollTop() >= initialOffset) {
if (!sticky) {
$("#cart").addClass("sticky");
sticky = true;
}
}
else {
if (sticky) {
$("#cart").removeClass("sticky");
sticky = false;
}
}
});

我认为删除
#target
中的right : 0;
应该可以。I think removing
right : 0;
in#target
should do.尝试以
ratio
(或百分比)而不是固定像素值的形式提供width
属性。例如 :
Try with providing the
width
attribute inratio
(or percent) rather than fixed pixel values.such as :
