无法隐藏对话模型答案

【问题标题】：can't hide dialog model无法隐藏对话模型
【发布时间】：2017-06-20 11:47:21
【问题描述】：

单击确定时我多次尝试隐藏对话框，但对话框无法隐藏

不使用 data-dismiss="modal"，因为当点击 OK 按钮然后关闭模型

我想当文本框为空时对话框不关闭，否则点击确定按钮关闭。

function btnModelOKClick() {
        if(validation())
        {
          // what write here code for hide dialog
        }
    }
    
function validation(){
  var name = $('#name').val();
  
  if(name == null || name == "")
  {
    return false;
  }
  return true;
}

请帮帮我

【问题讨论】：

不是模型是 $('#myModel')。模态 ('隐藏');
.modal('hide')的错字
而且模态ID是错误的。 id="myModal" $('#myModel').model('hide');
您找到想要的东西了吗？

标签： javascript jquery html

【解决方案1】：

你的问题在$('#myModel').model('hide');这一行。

它应该是.modal() 而不是.model()。并确保在$('#myModal') 中也使用正确的id="myModal"。

这是一个有效的演示：

function btnModelOKClick() {
        if(validation())
        {
          $('#myModal').modal('hide');
        }
    }
    
function validation(){
  var name = $('#name').val();
  
  if(name == null || name == "")
  {
    return false;
  }
  return true;
}

【解决方案2】：

试试

function hideModal(){
    $("#myModal").removeClass("in");
    $(".modal-backdrop").remove();
    $("#myModal").hide();
}

查看此 StackOverflow 讨论 Bootstrap modal hide is not working

【解决方案3】：

这只是一个拼写错误

更改$('#myModel').model('hide');

$('#myModal').modal('hide');

function btnModelOKClick() {
        if(validation())
        {
          $('#myModal').modal('hide');
        }
    }
    
function validation(){
  var name = $('#name').val();
  
  if(name == null || name == "")
  {
    return false;
  }
  return true;
}

以下代码应该可以工作：

<!DOCTYPE html>
<html lang = "en">
<head>
<title>Bootstrap Example</title>
<meta charset = "utf-8">
<meta name = "viewport" content = "width=device-width, initial-scale=1">

  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>

<div class="container">
  <h2>Example</h2>
  <button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open</button>

  <!-- Modal -->
  <div class="modal fade" id="myModal" role="dialog">
    <div class="modal-dialog">

      <!-- Modal content-->
      <div class="modal-content">
        <div class="modal-header">

          <h4 class="modal-title">Header</h4>
        </div>
        <div class="modal-body">
        Name : <input type="text" id="name" required/>
        </div>
        <div class="modal-footer">

        <button type="button" class="btn btn-default" id="modal-ok-button">OK</button>

          <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        </div>
      </div>

    </div>
  </div>

</div>


<script type="text/javascript">

$("#modal-ok-button").click(function(){

var name_text = $("#name").val();

if(name_text != null || name_text != ""){
    $('#myModal').modal('hide')
}
});

</script>


</body>
</html>

【解决方案5】：

你的模态ID是错误的，试试下面更正的一个（模型应该是模态的）

 $('#myModal').modal('hide');
