    <p>I have a form including two password fields (password, password confirmation). I need their issues about different values to look like a standard HTML-5 pop-up message (see the illustration pls). <img src="https://i.stack.imgur.com/aKcfd.gif" alt="enter image description here"> For this purpose I have attached the html5/JS function setCustomValidity() to the password2 field. Form.submin() triggers that checking. But the problem is that if values are different the message appears only starting from attempt #2. I.e. initial event does nothing - form doesn't send data but the message doesn't appears also. If I repeat this it appears. I have no any appropriate ideas why. Do you? Here is the full inner code:</p> <pre><code>&lt;script&gt; function validateForm(){ var pass1=document.getElementById('password1'); var pass2=document.getElementById('password2'); var pass1Val=pass1.value; var pass2Val=pass2.value; if(pass1Val&amp;&amp;pass2Val&amp;&amp;(pass1Val!=pass2Val)){ pass2.setCustomValidity("The password confirmation is different to the password value"); return false; } } &lt;/script&gt; &lt;form id="user-form" action="#" method="post" enctype="text/plain" onSubmit="return validateForm();"&gt; Email: &lt;input type="email" id="emailField" required="required"&gt; &lt;br&gt; Tel: &lt;input type="tel" id="phoneField" required="required"&gt; &lt;br&gt; Password: &lt;input type="password" id="password1" required="required"&gt; &lt;br&gt; Password2: &lt;input type="password" id="password2" required="required"&gt;&lt;br&gt; &lt;input type="submit" value="Send!"&gt; &lt;/form&gt; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
