将参数发送到Bootstrap模态窗口？ [英] Send parameter to Bootstrap modal window?

问题描述

我有一个问题，我无法将任何参数传递给模式窗口（使用Bootstrap 3），我尝试使用此链接中指出的解决方案，但无法使其工作：

将信息动态加载到Twitter Bootstrap模式 （按键kexxcream用户）。

但按下按钮，显示屏不显示任何东西，显然是块，附上下面的图片：

我附上了代码（左上方的代码相同）;

HTML代码：

 < div id =myModalclass =modal hide fade> 
< div class =modal-header> 
< button class =closedata-dismiss =modal>& times;< / button> 
< h3>标题< / h3> 
< / div> 
< div class =modal-body> 
< div id =modalContentstyle =display：none;> 
 
< / div> 
< / div> 
< div class =modal-footer> 
< a href =＃class =btn btn-infodata-dismiss =modal>关闭< / a> 
< / div> 
< / div> 
  

JS代码：

点击（功能（）
 {
 var essay_id = $（this）.attr（'id'）; $（$ [code> $（a [data-toggle = modal]） b 
 $ b $ .ajax（{
 cache：false，
 type：'POST'，
 url：'backend.php'，
 data：'EID ='+ essay_id，
成功：函数（数据）
 {
 $（'＃myModal'）。show（）; 
 $（'＃modalContent'）。show ）.html（data）; 
} 
}）; 
}）; 
  

按钮：

 < a href ='＃myModal'data-toggle ='modal'id ='2'>编辑< / a> 
  

PHP代码（backend.php）：

 <？php 
 $ editId = $ _POST ['EID']; 
？> 
< div class =jumbotron> 
< div class =container> 
< h1>选择的ID是<？php echo $ editId？>< / h1> 
< / div> 
< / div> 
  

解决方案

首先，您应该修复模式HTML 结构。现在这是不正确的，你不需要class .hide ：

 < div id =edit-modalclass =modal fadetabindex = -  1role =dialogaria-labelledby =myModalLabelaria-hidden =true> 
< div class =modal-dialog> 
< div class =modal-content> 
< div class =modal-header> 
< button type =buttonclass =closedata-dismiss =modalaria-hidden =true>& times;< / button> 
< h4 class =modal-titleid =myModalLabel>模式标题< / h4> 
< / div> 
< div class =modal-body edit-content> 
 ... 
< / div> 
< div class =modal-footer> 
< button type =buttonclass =btn btn-defaultdata-dismiss =modal>关闭< / button> 
< button type =buttonclass =btn btn-primary>保存更改< / button> 
< / div> 
< / div> 
< / div> 
< / div> 
  

然后链接应该通过 data-target

$ $ p $ < a href =＃myModaldata-toggle =modalid =1 data-target =＃edit-modal>编辑1< / a>


最后，Js部分变得非常简单：

<$ （'show.bs.modal'，function（e）{

var $ modal = $（this pre'$'code> $（'＃edit-modal'）。 ），
esseyId = e.relatedTarget.id;

$ .ajax（{
cache：false，
type：'POST'，
url ：'backend.php'，
data：'EID ='+ essayId，
成功：函数（数据）{
$ modal.find（'。edit-content'）。html数据）;
}
}）;
}）

I have a problem, I cannot pass any parameters to a modal window (using Bootstrap 3), I tried using the solution stated in this link, but I cannot make it work:

Dynamically load information to Twitter Bootstrap modal

(Solution kexxcream user).

But pressing the button, the display does not show me anything, apparently blocks, attached a picture below:

I have attached the code (same code post above left);

HTML Code:

      <div id="myModal" class="modal hide fade">
      <div class="modal-header">
        <button class="close" data-dismiss="modal">&times;</button>
        <h3>Title</h3>
      </div>
      <div class="modal-body">            
          <div id="modalContent" style="display:none;">

          </div>
      </div>
      <div class="modal-footer">
        <a href="#" class="btn btn-info" data-dismiss="modal" >Close</a>
      </div>
  </div> 

JS Code:

    $("a[data-toggle=modal]").click(function() 
    {   
        var essay_id = $(this).attr('id');

        $.ajax({
            cache: false,
            type: 'POST',
            url: 'backend.php',
            data: 'EID='+essay_id,
            success: function(data) 
            {
                $('#myModal').show();
                $('#modalContent').show().html(data);
            }
        });
    });

Button:

<a href='#myModal' data-toggle='modal' id='2'> Edit </a>

PHP Code (backend.php):

<?php
$editId = $_POST['EID'];
?>
  <div class="jumbotron">
   <div class="container">
    <h1>The ID Selected is <?php echo $editId ?></h1>
   </div>
  </div>

解决方案

First of all you should fix modal HTML structure. Now it's not correct, you don't need class .hide:

<div id="edit-modal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                <h4 class="modal-title" id="myModalLabel">Modal title</h4>
            </div>
            <div class="modal-body edit-content">
                ...
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                <button type="button" class="btn btn-primary">Save changes</button>
            </div>
        </div>
    </div>
</div>

Then links should point to this modal via data-target attribute:

<a href="#myModal" data-toggle="modal" id="1" data-target="#edit-modal">Edit 1</a>

Finally Js part becomes very simple:

    $('#edit-modal').on('show.bs.modal', function(e) {

        var $modal = $(this),
            esseyId = e.relatedTarget.id;

        $.ajax({
            cache: false,
            type: 'POST',
            url: 'backend.php',
            data: 'EID=' + essayId,
            success: function(data) {
                $modal.find('.edit-content').html(data);
            }
        });
    })
