问题描述
我需要在光标位置的 div
中获得悬停效果。
我有 html
和 css
.f {width:200px; height:200px;背景颜色:灰色;位置:固定; border-radius:100px;} .s {width:50px; height:50px;背景颜色:黑色; border-radius:100px; margin:75px 0px 0px 75px;过渡:宽度1s,高度1s,边距1s;}。s:hover {width:100px; height:100px;背景颜色:黑色; margin:50px 0px 0px 50px;}
< div class = F > < div class =s>< / div>< / div>
我需要这样的东西:
div>
要改变内圈的位置,你可以在mousemove上使用 pageX
和 pageY
。要更改内部圈的大小,您可以创建一个类,该类将< .f
。
var s = $('。s')var f = $ ('.f')var oTop = f.offset()。top +(s.height()/ 2); var oLeft = f.offset()。left +(s.width()/ 2); f。 hover(function(){s.toggleClass('change')})f.mousemove(function(e){var x = e.pageY - oTop var y = e.pageX - oLeft s.css({top:x + 'px',left:y +'px'})})
.f {width:200px; height:200px;背景颜色:灰色;位置:固定;溢出:隐藏; border-radius:100px;} .s {width:50px; height:50px;背景颜色:黑色; border-radius:100px;位置:绝对;指针事件:无;不透明度:0;转换:转换0.5s线性,不透明度0.3s线性;}。change {transform:scale(2); opacity:1;}
< script src =https ://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js>< / script>< div class =f> < div class =s>< / div>< / div>
I need get hover effect in a div
from the cursor position.
I have this html
and css
.f {
width: 200px;
height: 200px;
background-color: grey;
position: fixed;
border-radius: 100px;
}
.s {
width: 50px;
height: 50px;
background-color: black;
border-radius: 100px;
margin: 75px 0px 0px 75px;
transition: width 1s, height 1s, margin 1s;
}
.s:hover {
width: 100px;
height: 100px;
background-color: black;
margin: 50px 0px 0px 50px;
}
<div class="f">
<div class="s"></div>
</div>
And I need something like this:
I'm open to js or jquery solutions.
EDIT
I have a jquery solution:
$("div.f").mousemove(function(e) {
$('div.s').css({
left: e.clientX - 28,
top: e.clientY - 24
});
});
.f {
width: 200px;
height: 200px;
background-color: grey;
position: fixed;
border-radius: 100px;
/* comment or remove the overflow if necessary */
overflow: hidden;
}
.s {
position: absolute;
width: 50px;
height: 50px;
background-color: black;
border-radius: 100px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="f">
<div class="s"></div>
</div>
But i need the circle make the over animation like first snippet.

解决方案
To change position of inner circle you can use pageX
and pageY
on mousemove. To change size of inner circle you can create one class that will scale
div and toggle that class on hover over .f
.
var s = $('.s')
var f = $('.f')
var oTop = f.offset().top + (s.height() / 2);
var oLeft = f.offset().left + (s.width() / 2);
f.hover(function() {
s.toggleClass('change')
})
f.mousemove(function(e) {
var x = e.pageY - oTop
var y = e.pageX - oLeft
s.css({
top: x + 'px',
left: y + 'px'
})
})
.f {
width: 200px;
height: 200px;
background-color: grey;
position: fixed;
overflow: hidden;
border-radius: 100px;
}
.s {
width: 50px;
height: 50px;
background-color: black;
border-radius: 100px;
position: absolute;
pointer-events: none;
opacity: 0;
transition: transform 0.5s linear, opacity 0.3s linear;
}
.change {
transform: scale(2);
opacity: 1;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="f">
<div class="s"></div>
</div>
