Question

我正在使用拖动和放大器下载更新用户头像，我几乎完成了赌注，非常卡住并需要帮助。

对java不太熟悉..当用户拖动/删除新图像时，它会被写入数据库＆amp;正确上传。所有我想做的事情我认为很直接就是让帖子窗口通过Json返回已上传的图片，然后刷新页面，这将显示用户新的头像。

JavaScript重定向采用以下形式：

<script type="text/javascript">
    window.location = "http://www.google.com/"
</script>

更改此内容：

    <td class="preview">
        {{if thumbnail_url}}
        {window.location("http://www.mymusicwall.co.uk/avatar.asp");}                
        {{/if}}
    </td>

到此：

    <td class="preview">
        {{if thumbnail_url}}
        {<script type="text/javascript">window.location("http://www.mymusicwall.co.uk/avatar.asp");</script>}                
        {{/if}}
    </td>

修改

我不熟悉您的模板系统，但您需要将重定向放在模板之外。您可以将事件处理程序附加到您要在其后重定向的任何操作，然后如上所述在该事件处理程序中运行window.location。请务必检查您的控制台是否有错误，因为我确定您尝试的工作无法正常工作的大部分原因。

从帖子返回后，Javascript重定向无法正常工作
