javascript - 如何知道jquery模态对话框中选择了哪一行

我使用jquery对话框设计了一个页面。假设有 5 行，我想编辑或删除特定行，例如第三行。通过在谷歌搜索我得到了这个

$(document).ready(function(){
    $("#dlgConfirm").hide();
});
<!-- the following lines are for deleting the row-->
$(function() {
    $(".deleteRow").click(function(){
        var $row = $(this).parents('tr');
        $( "#dlgConfirm" ).dialog({
            resizable: false,
            height:140,
            modal: true,
            buttons: {
                "Delete selected Appointment": function() {
                    $row.remove();
                    $( this ).dialog( "close" );
                },
                Cancel: function() {
                    $( this ).dialog( "close" );
                }
            }
        });     
});
});

它从页面中删除，但我也需要从数据库中删除。所以我想知道如何获取列值和行值，以便我可以使用从表中删除，其中 row=3

![在此处输入图像描述][1]

显示表格代码如下

<%DataBaseConnection db=new DataBaseConnection();
        Connection con=db.connet();
        try
        {
            PreparedStatement pt= con.prepareStatement("select * from Appointments where login='"+session.getAttribute("login")+"' order by date desc");
            ResultSet rs=pt.executeQuery();
            while(rs.next())
            {
                %><tr>
                <td><%=rs.getString("Name") %></td>
                <td><%=rs.getString("Date") %></td>
                <td><%=rs.getString("StartTime") %></td>
                <td><%=rs.getString("EndTime") %></td>
                <td><%=rs.getString("Description") %></td>
                <td>
                    <!--<input type="button" id="edit" value="" onclick="" /><img src="edit.png">-->
<a href="#" class="edit-btn"><img src="edit.png" alt="edit">
                </td>
                <td>
                   <!-- <input type="button" id="delete" value="Delete" />-->
<a href="#" class="deleteRow"><img src="delete.png" height="20" width="20" alt="delete">
                </td>
            </tr>
            <%}
        }
        catch(Exception e)
        {
            out.println(e);
        }

当我编写以下代码时，我得到这种类型的输出

$(".deleteRow").click(function(){
        var rowid = $(this).parents('tr').attr('id');
        $( "#dlgConfirm" ).dialog({
            resizable: false,
            height:140,
            modal: true,
            buttons: {
                "Delete selected Appointment": function() {
                    removeRow(rowid);
                    $( this ).dialog( "close" );
                },
                Cancel: function() {
                    $( this ).dialog( "close" );
                }
            }
        }); 
});

function removeRow(rowid){

    $.ajax({
        url: 'deleteAppointments.jsp',
        data: {id: rowid}

        success: function(){
             $('table tr#'+rowid).remove();
        }
    });

}

deleteAppointments.jsp的代码如下

<%!String id;String login;int uid; %>
<%
id=request.getParameter("id");
uid=Integer.parseInt(id);
DataBaseConnection db=new DataBaseConnection();
login=(String)session.getAttribute("login");
Connection con=db.connet();
try{
PreparedStatement pt=con.prepareStatement("delete from Appointments where UID="+uid+" and login='"+login+"'");
int result=pt.executeUpdate();
}

最佳答案

每行都应该有一个 ID，用于标识数据库中的行。这样，您只需访问 Web 服务或 URL，为其提供您需要删除的 ID。 :

$(".deleteRow").click(function(){
        var rowid = $(this).parents('tr').attr('id');
        $( "#dlgConfirm" ).dialog({
            resizable: false,
            height:140,
            modal: true,
            buttons: {
                "Delete selected Appointment": function() {
                    removeRow(rowid);
                    $( this ).dialog( "close" );
                },
                Cancel: function() {
                    $( this ).dialog( "close" );
                }
            }
        }); 
});

function removeRow(rowid){

    $.ajax({
        url: 'myservice/deleteRow',
        data: {id: rowid}
        [some other stuff here...]
        success: function(){
             $('table tr#'+rowid).remove();
        }
    });

}

HTML我不知道你的 HTML 代码，所以我只画一个简单的例子

<table>
  <tr id="101">
   <td>User with id 101</td>
   <td class="deleteRow">Delete row</td>
  </tr>
</table>

编辑您的 JSP

<%DataBaseConnection db=new DataBaseConnection();
        Connection con=db.connet();
        try
        {
            PreparedStatement pt= con.prepareStatement("select * from Appointments where login='"+session.getAttribute("login")+"' order by date desc");
            ResultSet rs=pt.executeQuery();
            while(rs.next())
            {
                %><tr id="<%=rs.getString("UID") %>">
                <td><%=rs.getString("Name") %></td>
                <td><%=rs.getString("Date") %></td>
                <td><%=rs.getString("StartTime") %></td>
                <td><%=rs.getString("EndTime") %></td>
                <td><%=rs.getString("Description") %></td>
                <td>
                    <!--<input type="button" id="edit" value="" onclick="" /><img src="edit.png">-->
<a href="#" class="edit-btn"><img src="edit.png" alt="edit">
                </td>
                <td>
                   <!-- <input type="button" id="delete" value="Delete" />-->
<a href="#" class="deleteRow"><img src="delete.png" height="20" width="20" alt="delete">
                </td>
            </tr>
            <%}
        }
        catch(Exception e)
        {
            out.println(e);
        }

我在这里添加了您的结果集中的 ID，我在这里猜测，所以请适应。现在，当您生成行时，每一行都会将其 ID 设置为相应的 UID
