在这里,我试图在 iframe 中捕获图像(url)。但它不起作用。这是我的代码:

<div id="iframe">
    <table width="100%" border="0" align="left" cellpadding="0" cellspacing="0" class="border2">
        <tr>
            <td height="403">
                <asp:UpdatePanel ID="Update" runat="server" UpdateMode="Conditional">
                    <ContentTemplate>
                        <iframe id="IFTrendAnalysis" name="IFTrendAnalysis" scrolling="auto" runat="server" width="100%" height="403" frameborder="0"></iframe>
                    </ContentTemplate>
                    <Triggers>
                        <asp:AsyncPostBackTrigger ControlID="imgBTNSalesTrendChart" />
                    </Triggers>
                </asp:UpdatePanel>
            </td>
        </tr>
    </table>
</div>

和图像路径(动态生成)

http://10.232.151.132:8080/pentaho/getImage?image=picture658447691538512233.png

$(function () {
    $("#MainContent_IFTrendAnalysis img").click(function () {
        var update = $("<div>").append(
            $("<img>").attr("src", $(this).attr("src"))
        ).html();

        $("#content").val(function (i, v) {
            return v + update;
        });
    });
});

有什么建议么?

如果您的 iframe 页面与父页面位于同一域中,那么这应该可以帮助您:

var name = "img_Sample";
$('#MainContent_iframeDetail').get(0).contentWindow.document.getElementById(name).src

我认为,您也应该能够使用 Jquery 来代替document.getElementByID
