单击表格行(使用引导程序)时，如何使用模式显示数据? [英] How can I show data using a modal when clicking a table row (using bootstrap)?

问题描述

我是整个Web开发领域的初学者，经过大量研究后，我仍然无法完成这项工作.很感谢任何形式的帮助.我正在使用最新的Rails版本和引导程序来使事情更漂亮.

I'm sort of a beginner on the whole web development thing and after researching a lot I still couldn't get this done. Any help is very much appreciated. I'm using latest rails version and bootstrap to make things prettier.

我有一个带有表格的页面，其中包含来自餐厅的订单.如果单击一行，我希望它使用引导程序在模式窗口中显示订单详细信息.我已经设法通过onclick + javascript函数打开模态，但是看起来有点混乱，我仍然不知道如何使用订单信息加载模态的内容div.这是我的代码:

I have a page with a table which contains orders from a restaurant. If you click a row I want it to show the order details in a modal window using bootstrap. I have managed to open the modal via onclick+javascript function but it looks kinda messy and I still have no clue how to load the content div of the modal with the order info. Here's the code I have for this:

HTML:

<h1>Orders</h1>
<table class="table table-striped"
  <thead>
    <tr>
      <th>ID</th>
      <th>Customer</th>
      <th>Status</th>
    </tr>
  </thead>
  <tbody>
    <% @restaurant.orders.each do |order| %>
    <tr onclick="orderModal(<%= order.id  %>);">
      <td><%= order.id %></td>
      <td><%= order.customer_id %></td>
      <td><%= order.status %></td>
    </tr>
    <% end %>
  </tbody>
</table>

<div id="orderModal" class="modal hide fade" role="dialog" 
     aria-labelledby="orderModalLabel" aria-hidden="true">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal" aria-hidden="true">x</button>
    <h3>Order</h3>
  </div>
  <div id="orderDetails"class="modal-body"></div>
  
  <div id="orderItems" class="modal-body"></div>
  <div class="modal-footer">
    <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
  </div>
</div>

js:

function orderModal(order_id){
    $('#orderModal').modal({
        keyboard: true,
        backdrop: "static"
    });
};

推荐答案

您可以做的一件事是摆脱所有这些onclick属性，并使用引导程序正确执行此操作.您无需手动打开它们；您可以指定触发器，甚至可以在模式打开之前预订事件，以便您可以进行操作并在其中填充数据.

One thing you can do is get rid of all those onclick attributes and do it the right way with bootstrap. You don't need to open them manually; you can specify the trigger and even subscribe to events before the modal opens so that you can do your operations and populate data in it.

我将以静态示例的形式展示您可以在现实世界中看到的示例.

I am just going to show as a static example which you can accommodate in your real world.

在每个< tr> 上，为具有相应ID的 id (即 data-id )添加一个数据属性值并指定 data-target (这是您指定的选择器)，以便在单击时，引导程序将选择该元素作为模式对话框并显示它.然后，您需要添加另一个属性 data-toggle = modal ，以使其成为模式触发器.

On each of your <tr>'s add a data attribute for id (i.e. data-id) with the corresponding id value and specify a data-target, which is a selector you specify, so that when clicked, bootstrap will select that element as modal dialog and show it. And then you need to add another attribute data-toggle=modal to make this a trigger for modal.

  <tr data-toggle="modal" data-id="1" data-target="#orderModal">
            <td>1</td>
            <td>24234234</td>
            <td>A</td>
  </tr>
  <tr data-toggle="modal" data-id="2" data-target="#orderModal">
            <td>2</td>
            <td>24234234</td>
            <td>A</td>
        </tr>
  <tr data-toggle="modal" data-id="3" data-target="#orderModal">
            <td>3</td>
            <td>24234234</td>
            <td>A</td>
  </tr>

现在，在javascript中，只需设置一次模态，然后事件监听其事件，以便您可以进行工作.

And now in the javascript just set up the modal just once and event listen to its events so you can do your work.

$(function(){
    $('#orderModal').modal({
        keyboard: true,
        backdrop: "static",
        show:false,

    }).on('show', function(){ //subscribe to show method
          var getIdFromRow = $(event.target).closest('tr').data('id'); //get the id from tr
        //make your ajax call populate items or what even you need
        $(this).find('#orderDetails').html($('<b> Order Id selected: ' + getIdFromRow  + '</b>'))
    });
});

请勿再使用内联点击属性.使用事件绑定代替香草js或jquery.
