Question

我正在尝试使用jquery和web处理程序在服务器上上传文件。一切正常，但问题是当我点击文件上传控件时弹出一个文件选择窗口，我选择文件后直接启动文件上传。我的问题是我想在不同控件的点击事件上上传文件（即点按钮点击事件）。

这是我目前正在使用的代码。

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script src="jquery-1.2.6.min.js" type="text/javascript"></script>
    <script src="jquery.ajax_upload.0.6.min.js" type="text/javascript"></script>
    <link href="default.css" rel="stylesheet" type="text/css" />

    <script type="text/javascript" language="javascript">
        $(document).ready(function () {

            var button = $('#fuAttachment'), interval;
            $.ajax_upload(button, {
                action: 'FileUploader.ashx',
                name: 'myfile',
                onSubmit: function (file, ext) {
                    if (ext == "jpg") {
                        return true;
                    }
                    else {
                        alert("Invalid File Type.");
                        return false;
                    }
                    //  this.disable();
                },
                onComplete: function (file, response) {
                    window.clearInterval(interval);
                    $('<li></li>').appendTo('.files').text(file);
                }
            });
        });
    </script>
</head>

                                <input type="submit" runat="server" name="Submit" value="Submit" id="btnSub" />

                </td>
            </tr>
            <tr>
                <td colspan="2">
                    <ol class="files">
                    </ol>
                </td>
            </tr>
        </table>
    </div>
    </form>
</body>
</html>

我希望我的上传过程应该从btnSub点击事件开始。如果有人知道请帮助我.........
