Javascript 如何在模态动作url中设置值

单击“删除按钮”时，“模式删除按钮”链接具有“删除按钮”中的值。 我的代码

$（文档）。在（“单击”，“我的模态”，函数（e）{
e、 预防默认值（）；
var _self=$（本）；
var myBookId=_self.data（'adid'）；
$（“adid”）.val（myBookId）；
$（_self.attr（'href'））.modal（'show'）；
});

删除按钮代码

print'<td><button class="btn btn-danger" data-toggle="modal" id="myModal" data-target="#myModal" data-adid='.$cd[$i][0].'>Delete Item</a></button>

print'删除项目

模态码

<div class="modal fade" id="myModal" 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">Heads Up!
                     <p>What you are doing will delete a data!</p></h4>
      </div>

      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-success"><a href="a=yes&adid=" >Delete</a></button>
      </div>
    </div>
  </div>
</div>

小心！
您正在执行的操作将删除一个数据

关

单击“删除项目”按钮，然后显示模式，此模式删除链接的url类似于

？a=yes&adid=

在

&adid

之后，有一个来自删除项目数据adid的值

但是我的代码不起作用

首先，删除按钮和模式都有相同的id（myModal）。 试试下面的代码

<button class="btn btn-danger" data-toggle="modal" id="deleteBtn" data-target="#myModal" data-adid='.$cd[$i][0].'>Delete Item</button>

<div class="modal hide" id="myModal"  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">Heads Up!
                         <p>What you are doing will delete a data!</p></h4>
          </div>

          <div class="modal-footer">
            <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
            <button type="button" class="btn btn-success"><a href="" >adid=''</a></button>
          </div>
        </div>
      </div>
</div>

选中此复选框，我使用您的代码，但不在a=yes&adid中添加任何值=

<button class="btn btn-danger" data-toggle="modal" id="deleteBtn" data-target="#myModal" data-adid='.$cd[$i][0].'>Delete Item</button>

<div class="modal hide" id="myModal"  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">Heads Up!
                         <p>What you are doing will delete a data!</p></h4>
          </div>

          <div class="modal-footer">
            <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
            <button type="button" class="btn btn-success"><a href="" >adid=''</a></button>
          </div>
        </div>
      </div>
</div>

$(document).on("click", "#deleteBtn", function (e) {
    e.preventDefault();
    e.stopPropagation();
    var link = $(this).attr('data-adid');        
    $("#myModal .btn-success a").attr('href',link);
    $(".modal").modal("show");
});
