本文实例讲解了javascript实现右侧弹出“分享到”窗口的详细代码，分享给大家供大家参考，具体内容如下

具体代码：

<html>

<head>

body {

padding: 0;

margin: 0;

}

#div1 {

width: 100px;

height: 150px;

background-color: #1B6D85;

left:-100px;

position: absolute;

}

#div1 span {

width: 20px;

height: 100px;

line-height: 30px;

background-color:#1B6D85;

left:100px;

top:20px;

position: absolute;

}

</style>

window.onload = function() {

var oDiv1 = document.getElementById('div1');

oDiv1.timer = null;

oDiv1.onmouseover = function() {

startMove(this, 0);

};

oDiv1.onmouseout = function() {

startMove(this, -100);

};

window.onscroll = function () {

var oDiv1 = document.getElementById('div1');

var ioffsetMiddle = document.documentElement.scrollTop || document.body.scrollTop;

ioffsetMiddle = ioffsetMiddle + (document.documentElement.clientHeight - oDiv1.offsetHeight) / 2;

//防止有小数，导致一直跳动

ioffsetMiddle = parseInt(ioffsetMiddle);

startMiddle(oDiv1, ioffsetMiddle);

};

function startMiddle(obj, iTarget) {

clearInterval(obj.timerMiddle);

obj.timerMiddle = setInterval(function () {

var speed = (iTarget - obj.offsetTop) / 8;

//如果大于零就取上，小于零就取下

speed = speed > 0 ? Math.ceil(speed) : Math.floor(speed);

document.getElementById('input1').value = iTarget + '-' + (obj.offsetTop + speed);

if (obj.offsetTop == iTarget) {

clearInterval(obj.timerMiddle);

} else {

obj.style.top = obj.offsetTop + speed + 'px';

}

}, 10);

}

function startMove(obj, iTarget) {

clearInterval(obj.timer);

obj.timer = setInterval(function () {

var speed = (iTarget - obj.offsetLeft) / 8;

speed = speed > 0 ? Math.ceil(speed) : Math.floor(speed);

if (obj.offsetLeft == iTarget) {

clearInterval(obj.timer);

} else {

obj.style.left = obj.offsetLeft + speed + 'px';

}

}, 10);

}

</script>
