代碼
復制代碼 代碼如下:
<body>
<div id="block" style="width:100px; height:100px; position:relative; background-color:#FF0000";></div>
<script>
var bb = document.getElementById("block");
bb.onmousedown = function(){
//獲取鼠標當前坐標
var pageX = event.clientX;
var pageY = event.clientY;
//獲取block的坐標，左邊界和上邊界
var offX = parseInt(this.style.left)||0;
var offY = parseInt(this.style.top)||0;
//計算出鼠標坐標相對于block坐標的間距
var offLX = pageX-offX;
var offLY = pageY-offY;
if(!document.onmousemove){
document.onmousemove = function(){
bb.style.left=event.clientX-offLX; //設置block的X坐標
bb.style.top=event.clientY-offLY; //設置block的Y坐標
}
}
}
document.onmouseup = function(){document.onmousemove = null;} //鼠標彈起
</script>
</body>
