如何在提交表单时显示引导程序模式?

问题描述

我正在填写表格.因此，我在所有字段中都设置了javascript验证.我希望仅当用户单击提交"按钮

I am making a form. So in that i have set javascript validation for all the fields. I want the modal to pop-up only if the form is valid when the user clicks the submit button

请仅使用js建议答案.我对jquery也不太熟悉.请不要让我将验证更改为jquery(因为上次我问有关验证的问题时，有人告诉我要更改它).我试图将onsubmit添加到<form>，但是它不起作用

Pls suggest answers only using js. I not very familiar with jquery as well.Pls don't ask me to change my validation to jquery(because last time when i had asked a question about validation people told me to change it). I have tried to add onsubmit to <form> but it doesn't work

我的模态

  <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">
          <p>Some text in the modal.</p>
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        </div>
      </div>

    </div>
  </div>

我的按钮和验证码

<div class="row container">
                <div class="col-sm-4"><label>Text<input class="form-control" type="text" required>
            </label>
                </div>
                <div class="col-sm-4"><label>Text<input class="form-control" type="text" required>
            </label></div>
                <div class="col-sm-4"><label>Text<input class="form-control" type="text" required>
            </label></div>
            </div>
<!-- Trigger the modal with a button -->
  <button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button></form>

但是正如您所看到的，当我按下按钮时，模态弹出.但是我希望它在提交时弹出.我什至尝试使用<form onsubmit>

But as you can see the modal pops up when i press the button. But i want it to pop-up onsubmit. I even tried using <form onsubmit>

推荐答案

JS

function myfn() {
  $('#myModal').modal('show');
}

HTML

<form onsubmit="event.preventDefault(); myfn()">
//all inputs and other info
</form>
