【问题标题】：How to pass variables to a modal from a link如何从链接将变量传递给模态

【问题描述】：

我有一个带有一些链接的导航栏。链接都触发相同的模式，但我需要根据链接在模式内显示不同的信息。我更喜欢非 jQuery 解决方案，但如果有必要，我会接受。

我试过了……

firstpage.php

    <li><a href="#theModal?viewmessages=mymessages" data-toggle="modal">My Messages</a></li>
    <li><a href="#theModal?viewnotifications=mynotifications" data-toggle="modal">My Notifications</a></li>

<!---Modal -->
  <div id="theModal" class="modal fade text-center">
    <div class="modal-dialog modal-lg">
      <div class="modal-content">
          <?php include 'modal.php';?>
      </div>
    </div>
  </div>
 <!-- Modal -->

modal.php

<!--
=============================
ISSET_GET MESSAGES 
=============================-->
<div class="modal-header">
        <button type="button" class="close" data-dismiss="modal">&times;</button>
        <h4 class="modal-title">Messages</h4>
      </div>
      <div class="modal-body">
        <p>some text here</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
<!--
=============================
ISSET_GET NOTIFICATIONS
=============================-->
<div class="modal-header">
        <button type="button" class="close" data-dismiss="modal">&times;</button>
        <h4 class="modal-title">Notifications</h4>
      </div>
      <div class="modal-body">
        <p>some text here</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>

【问题讨论】：

你想将什么数据传递给模态？
在firstpage.php 中设置的变量应该可以在modal.php 中访问。有多少内容需要改变？您可以将所有模式都放在页面底部。并在您的每个链接中设置data-target="#the-id-of-your-modal"。看看我的例子w3schools.com/code/tryit.asp?filename=FEWFXWWS2918

【解决方案1】：

我认为您应该在页面底部呈现所有模式并使用 jQuery 加载与链接关联的模式。

例如

<button type="button" class="btn btn-info btn-lg" id="myBtn1">Open Modal 1</button>

然后使用 jQuery 将引导程序 .modal() 函数绑定到按钮的单击事件。您可以在此处设置要加载的模式，例如。

$("#myBtn1").click(function(){
    $("#myModal1").modal();
});
