<p>Based on your comment above...</p>

<blockquote>
  <p>I am trying to do a form where if the user enters wrong credentials
  the modal will pop up.</p>
</blockquote>

<p>...maybe this will help. If not, then you need to clarify what you're trying to do in your question.</p>

<p>In the snippet below, I have a login form. When the wrong credentials are entered, the modal appears.</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>$("#login").click(function () {
    // Here you would do your check for correct credentials
    // Obviously you wouldn't want to do this in JS in production
    // I'm assuming there would be an AJAX request here that would validate the user's credentials
    // If valid, proceed. If not, call the modal.
    if ($(username).val() !== "blah" || $(password).val() !== "blah") {
  	// Username or password incorrect, show modal
    $("#modal").modal();
  } else {
  	alert("Login successful!");
  }
})</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css"&gt;
&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"&gt;&lt;/script&gt;
&lt;script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/js/bootstrap.min.js"&gt;&lt;/script&gt;


Username: &lt;input id="username" type="text" /&gt;
Password: &lt;input id="password" type="password" /&gt;
&lt;button type="button" id="login" class="btn btn-info"&gt;Login&lt;/button&gt;

&lt;div class="modal fade" id="modal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true"&gt;
  &lt;div class="modal-dialog" role="document"&gt;
    &lt;div class="modal-content"&gt;
      &lt;div class="modal-header"&gt;
        &lt;h5 class="modal-title" id="exampleModalLabel"&gt;Ready to Leave?&lt;/h5&gt;
        &lt;button class="close" type="button" data-dismiss="modal" aria-label="Close"&gt;
            &lt;span aria-hidden="true"&gt;×&lt;/span&gt;
          &lt;/button&gt;
      &lt;/div&gt;
      &lt;div class="modal-body"&gt;Username or Password is incorrect.&lt;/div&gt;
      &lt;div class="modal-footer"&gt;
        &lt;a class="btn btn-primary" data-dismiss="modal"&gt;Try again&lt;/a&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;
&lt;/div&gt;</code></pre>
</div>
</div>
</p>

<p>Basically, anytime you want the modal to appear automatically (i.e., without clicking on anything), just call it like this:</p>

<pre><code>$("#idOfModal").modal();
</code></pre>

<p>If you want to programmatically hide or dismiss the modal, you can do that by passing <code>hide</code> to the <code>modal</code> function:</p>

<pre><code>$("#idOfModal').modal("hide");
</code></pre>
