摘要:html组件实现可拖动效果
不知道大家进163的邮件有没有发现上面的邮件是可以拖动的,本想看看它的原码是如果实现,但由于本人水平太次,不能找到其中的原码,后面通过网上找到一些代码,修改了些基本上能实现此种效果,html代码如下:
<style>
<!--
.drag{position:relative;cursor:hand}
-->
</style>
<script >
<!--
var dragapproved=false
var z,x,y
var xx,yy
function move(){
if ( z==null){ ; return}
if (event.button==1&&dragapproved){
z.style.pixelLeft=temp1+event.clientX-x
z.style.pixelTop=temp2+event.clientY-y
return false
}
}
function moveto(){
z.style.pixelLeft= xx
z.style.pixelTop= yy
z=null
}
function drags(){
if (!document.all)return
if (event.srcElement.className=="drag"){
dragapproved=true
z=event.srcElement
if ( z==null){ return}
temp1=z.style.pixelLeft
temp2=z.style.pixelTop
xx=z.style.pixelLeft
yy=z.style.pixelTop
x=event.clientX
y=event.clientY
document.onmousemove=move
}
}
function drags1(){
if ( z==null){ ; return}
if (z.className=="drag"){
//z=event.srcElement
//alert(z.type);
temp1=z.style.pixelLeft
temp2=z.style.pixelTop
x=event.clientX
y=event.clientY
moveto()
}
}
document.onmousedown=drags
document.onmouseup=drags1
Function("dragapproved=false")
//-->
</script>
