Question

我正在使用以下引导代码来显示一个模态，现在我想从输入字段中获取值。我尝试了很多方法，但未能使用javascript获取数据。

<div aria-hidden="true" aria-labelledby="myModalLabel" role="dialog" tabindex="-1" id="myModal" class="modal fade">
    <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">Forgot Password ?</h4>
            </div>
            <div class="modal-body">
                <p>Enter your employee id below to reset your password.</p>
                <input type="text" name="getId" placeholder="Employee id" autocomplete="off" class="form-control placeholder-no-fix">

            </div>
            <div class="modal-footer">
                <button data-dismiss="modal" class="btn btn-default" type="button">Cancel</button>
                <button class="btn btn-primary" btn="submt" type="button">Submit</button>
            </div>
        </div>
    </div>
</div>

 $(document).ready(function () {

            var btnSubmit = $(element).parent().prev().find("#submt");

            $(btnSubmit).click(function()
            {
                //var ids = $('getId').val();
                var ids = $(element).parent().prev().find("#getID");
                alert(ids);

                $.ajax({
                    url:'rtrv_pass.php',
                    type:'post'
                    //data:{uid:},
                });
            });

        });

尝试使用以下代码，它可以帮助您解决问题。

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Forgot Password ?</h4>
      </div>
      <div class="modal-body">
        <p>Enter your employee id below to reset your password.</p>
        <input type="text" name="getId" placeholder="Employee id" autocomplete="off" class="form-control placeholder-no-fix">
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
        <button type="button" class="btn btn-primary">Submit</button>
      </div>
    </div>
  </div>
</div>
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch demo modal
</button>

我刚修改了点击事件代码..

Jquery的：

$('#btnSubmit').click(function () {

        var textFieldVal = $('input[name="getId"]').val();


        $.ajax({
            url: 'rtrv_pass.php',
            type: 'post'
            //data:{uid:},
        });

    });

Answer 3

您可以使用jquery代码获取输入文本字段的值

   var input_value = $("#myModal").find('input').val();

Answer 4

在提交按钮中添加唯一ID：

<button id="uniqueId" class="btn btn-primary" btn="submt" type="button">Submit</button>

$(document).ready(function () {


            $('#uniqueId').click(function()
            {
                var ids = $(this).closest('.modal-dialog').find('input[name="getID"]');
                alert(ids);

                $.ajax({
                    url:'rtrv_pass.php',
                    type:'post'
                    //data:{uid:},
                });
            });

我建议你在跳转到代码之前首先阅读关于类，id，dom，编程的一些内容
