javascript - 引导模态确认

Question

我有一个表格，每行显示用户详细信息，以及一个启动 Bootstrap 模式确认对话框的删除按钮。

我的目标是让确认按钮触发一个事件，该事件将删除该特定用户。

我如何将表行中的 jsmith22 传递到我的 Javascript 函数中？

HTML 表格

<tr>
    <td>jsmith22</td>
    <td>John Smith</td>
    <td>555-555-5555</td>
    <td>test@gmail.com</td>
    <td><button type="button" class="btn btn-default btn-lg btn-block roster-button active" data-toggle="modal" data-target="#removeUser">Remove</button></td>
</tr>

模态对话框

<div aria-labelledby="myModalLabel" class="modal fade" id="removeUser"
role="dialog" tabindex="-1">
    <div class="modal-dialog" role="document">
        <div class="modal-content">
            <div class="modal-header">
                <h4 class="modal-title">Remove Employee</h4>
            </div>
            <div class="modal-body">
                <p>Are you sure you wish to remove this user?</p>
            </div>
            <div class="modal-footer">
                <button class="btn btn-default" data-dismiss="modal" type="button">Cancel</button>
                <button class="btn btn-danger" id="remove-button" type="submit">Remove</button>
            </div>
        </div><!-- end modal-content -->
    </div><!-- end modal-dialog -->
</div><!-- end modal -->

Javascript

// Remove button event trigger
$('#remove-button').click(function() {
        $.post('/API/removeUser', {} );
});

Answer 1

可以用 Bootstrap Modal event listener 来做

给模态触发按钮添加数据属性data-id

<td><button type="button" data-id="jsmith22" data-toggle="modal" data-target="#removeUser" class="btn btn-default btn-lg btn-block roster-button active">Remove</button></td>

将输入 type="hidden" 添加到模态，并在显示时将 id 值传递给模态隐藏输入

隐藏输入

<input type="hidden" id="RowId" value="">

模态事件显示脚本

$(document).ready(function(){
    $('#removeUser').on('show.bs.modal', function (e) {
        var id = $(e.relatedTarget).data('id');
        $('#RowId').val(id);
     });
});

现在有了click事件

$('#remove-button').click(function() {
        var delid = $('#RowId').val();
        //Do what ever you like to do
        $.post('/API/removeUser', {} );
});

替代解决方案

您可以跳过隐藏输入并创建一个全局变量

模态触发按钮，数据属性data-id为模态触发按钮

<td><button type="button" data-id="jsmith22" data-toggle="modal" data-target="#removeUser" class="btn btn-default btn-lg btn-block roster-button active">Remove</button></td>

Modal Event, Click function with Global variable script

$(document).ready(function() {
  var delid = ''; //global variable
  $('#removeUser').on('show.bs.modal', function(e) {
    delid = $(e.relatedTarget).data('id'); //fetch value of `data-id` attribute load it to global variable
    alert(delid);
  });

  $('#remove-button').click(function() {
    alert(delid); //Use the global variable here to del the record
    //Do what ever you like to do
    //$.post('/API/removeUser', {} );
  });
});
