Bootstrap 模态中的 Sweet Alert

Question

我有一个 javascript 函数可以根据用户输入调用 sweetalert，但 sweet alert 在 bootstrap 模型中不起作用。

谁能帮帮我

<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>   

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

  <!-- Modal content-->
  <div class="modal-content">
    <div class="modal-header">
      <button type="button" class="close" data-dismiss="modal">&times;</button>
      <h4 class="modal-title">Modal Header</h4>
    </div>
    <div class="modal-body">
      <input type="text" id="input1" onblur="alerts()">
    </div>
    <div class="modal-footer">
      <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
    </div>
  </div>
</div>
 </div>

JavaScript:

function alerts()
{
  var inputs = document.getElementById("input1").value;
  if(inputs < 2)
  {
  swal('Not Valid', 'Enter another','warning');
  }
}

我不是 JavaScript 的忠实粉丝，所以不确定为什么它不能与 blur() 一起使用，但你可以使用 jQuery keyup 函数

$(document).ready(function () {
  $('#input1').keyup(function () {
    var inputs = $(this).val();
    if (inputs < 2) {
      swal('Not Valid', 'Enter another', 'warning');
    }
  });
});

      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal">&times;</button>
        <h4 class="modal-title">Modal Header</h4>
      </div>
      <div class="modal-body">
        <input type="text" id="input1" class="form-control">
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>

只需要稍微重新排序您的函数

http://jsfiddle.net/link2twenty/oj5cfp6j/

alerts = function () {
  var inputs = document.getElementById("input1").value;
  if (inputs < 2) {
    swal('Not Valid', 'Enter another', 'warning');
  }
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/sweetalert/1.1.3/sweetalert.min.js"></script>
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>

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

<!-- Modal content-->
<div class="modal-content">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal">&times;</button>
    <h4 class="modal-title">Modal Header</h4>
  </div>
  <div class="modal-body">
    <input type="text" id="input1" onblur="alerts()">
  </div>
  <div class="modal-footer">
    <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
  </div>
</div>
  </div>
</div>
