一個拖動效果,根據論壇的一些帖子改的,但還有一些BUG一直沒法解決,誰能幫我改改?
當第一次拖動層時,層的位置會偏離很遠。
呃。。。這涉及到一個style的問題。。。
在ie和firefox中,obj.style這個東西實際上只是取得元素中屬性style中的值!
如下例,你會發現style塊中的屬性一個都取不到!
<style>
#test{width:100px;background-color:red;}
</style>
<script>
window.onload=function(){
var t=document.getElementById('test')
var ts=t.style;
t.innerHTML=
"t.style.width:"+ts.width+"<br />"+
"t.style.backgroundColor:"+ts.backgroundColor+"<br />"+
"t.style.color:"+ts.color+"<br />"+
"t.style.paddingLeft:"+ts.paddingLeft
}
</script>
<body>
<div id="test" style="color:yellow;padding-left:100px;">
</div>
</body>
看到了沒?前兩個style 為空,后兩個才有值。
如果是ie,問題很好解決,只要把style改成currentStyle即可。
IE Only
<style>
#test{width:100px;background-color:red;}
</style>
<script>
window.onload=function(){
var t=document.getElementById('test')
var ts=t.currentStyle;
t.innerHTML=
"t.style.width:"+ts.width+"<br />"+
"t.style.backgroundColor:"+ts.backgroundColor+"<br />"+
"t.style.color:"+ts.color+"<br />"+
"t.style.paddingLeft:"+ts.paddingLeft
}
</script>
<body>
<div id="test" style="color:yellow;padding-left:100px;">
</div>
</body>
FF only
<style>
#test{width:100px;background-color:red;}
</style>
<script>
window.onload=function(){
var t=document.getElementById('test')
var ts=document.defaultView.getComputedStyle(t, null);
t.innerHTML=
"t.style.width:"+ts.width+"<br />"+
"t.style.backgroundColor:"+ts.backgroundColor+"<br />"+
"t.style.color:"+ts.color+"<br />"+
"t.style.paddingLeft:"+ts.paddingLeft
}
</script>
<body>
<div id="test" style="color:yellow;padding-left:100px;">
</div>
</body>
我繞了半天,你明白你的錯誤原因了嗎?你的style全都是文檔級style,而你試圖獲取left的時候,第一次獲得的只是0,自然會把你的框給挪到邊上去了。
