代碼如下:
    <div id="localImag"><img id="preview" width="-1" height="-1" /></div>
    <asp:FileUpload ID="file_head" runat="server" onchange="javascript:setImagePreview();" />
    代碼如下:
    <script type="text/javascript">
    function setImagePreview() {
    var docObj = document.getElementById("ctl00_ContentMain_file_head");
    var fileName = docObj.value;
    if (!fileName.match(/.jpg|.gif|.png|.bmp/i)) {
    alert('您上傳的圖片格式不正確，請重新選擇！');
    return false;
    }
    var imgObjPreview = document.getElementById("preview");
    if (docObj.files && docObj.files[0]) {
    //火狐下，直接設(shè)img屬性
    imgObjPreview.style.display = 'block';
    imgObjPreview.style.width = '63px';
    imgObjPreview.style.height = '63px';
    //imgObjPreview.src = docObj.files[0].getAsDataURL();
    if (window.navigator.userAgent.indexOf("Chrome") >= 1 || window.navigator.userAgent.indexOf("Safari") >= 1) {
    imgObjPreview.src = window.webkitURL.createObjectURL(docObj.files[0]);
    }
    else {
    imgObjPreview.src = window.URL.createObjectURL(docObj.files[0]);
    }
    } else {
    //IE下，使用濾鏡
    docObj.select();
    docObj.blur();
    var imgSrc = document.selection.createRange().text;
    var localImagId = document.getElementById("localImag");
    //必須設(shè)置初始大小
    localImagId.style.width = "63px";
    localImagId.style.height = "63px";
    //圖片異常的捕捉，防止用戶修改后綴來偽造圖片
    try {
    localImagId.style.filter = "progid:DXImageTransform.Microsoft.AlphaImageLoader(sizingMethod=scale)";
    localImagId.filters.item("DXImageTransform.Microsoft.AlphaImageLoader").src = imgSrc;
    } catch (e) {
    alert("您上傳的圖片格式不正確，請重新選擇！");
    return false;
    }
    imgObjPreview.style.display = 'none';
    document.selection.empty();
    }
    return true;
    }
    </script>
    此js解決360瀏覽器顯示圖片問題。因?yàn)?60瀏覽器6.2用的是Chrome的內(nèi)核，而
    代碼如下:
    window.URL.createObjectURL(docObj.files[0]);
