在頁面上放入一個上傳控件和一個圖片控件.
<asp:FileUpload ID="FileUpload1" runat="server" onpropertychange="show(this.value)"/>
<asp:Image ID="Image1" runat="server" />
在上傳控件中寫onpropertychange="show(this.value)"事件并調(diào)用js中的show函數(shù)并將自身的參數(shù)傳進js.
<script type="text/javascript">
function show(id)
...{
document.getElementById("Image1").src=id;
}
</script>
Ie6,Ie7測試通過(注要通過濾器實現(xiàn))
<div id="divview" style="filter : progid:DXImageTransform.Microsoft.AlphaImageLoader(sizingMethod=image);WIDTH: 166px; HEIGHT: 190px">
<!--用于顯示圖片-->
</div>
<asp:FileUpload ID="FileUpload3" runat="server" onpropertychange="show1(this.value)"/>
<script type="text/javascript">
function show1(upimg)
...{
var dd=document.getElementById("divview");
dd.filters.item("DXImageTransform.Microsoft.AlphaImageLoader").src = upimg;
dd.style.width = 166;
dd.style.height = 190;
dd.filters.item("DXImageTransform.Microsoft.AlphaImageLoader").sizingMethod = scale;
}
</script>
