好吧,我只是编造了这个,它有点马车,但你可以玩弄它。
<html>
<head>
<style>
#mydiv{
width: 100px;
height: 100px;
border: solid black 1px;
position: absolute;
}
</style>
</head>
<body>
<div id="mydiv" onmousedown="ismousedown(1)" onmouseup="ismousedown(0)" onmousemove="mousemove(event)"></div>
<script>
var mousedown = false;
function ismousedown(tf){
if(tf == 1){
mousedown = true;
}
else{
mousedown = false;
}
}
function mousemove(event){
if(mousedown){
document.getElementById("mydiv").style.left=event.pageX;
document.getElementById("mydiv").style.top=event.pageY;
}
}
</script>
</body>
