How to check validation? about bootstrap-validate HOT 2 CLOSED

You can look for the existance of any error classes on the form submission event :)

Currently on mobile, but its alike of

document.getElementById('myform').addEventListener('submit', function (e) {

  e.preventDefault();
  if (document.querySelector('.has-error')) {
    alert('Fix form errors first');
  }
});

from bootstrap-validate.

@bar15150 If you are still looking for a solution for this, you can do the following:

1. Give your form an ID so that you can refer to it in Javascript.
2. Then write event.preventDefault() so that the form won't be submitted when the user clicks submit.
3. Write a new function called validateForm() that is supposed to submit the form once it's valid.
4. Include jQuery in your HTML. You will need it to find "form errors".

Let's put this all together:

Here is an example of your form tag:

<form method="POST" id="formSignup" onsubmit="event.preventDefault(); validateForm();">
</form>

Add this code before your </body> tag:

<script src="https://code.jquery.com/jquery-3.5.1.min.js" crossorigin="anonymous"></script>
<script>
	function validateForm()
	{
		//Find the number of form errors shown
		var numInvalid = $( "#formSignup" ).find( ".invalid-feedback:not(:hidden)" ).length;

		if (numInvalid == 0) {
			//No errors, submit form
			document.getElementById("formSignup").submit();	//All is good. Submit form.
		}
		else {
			//Errors found, do not submit
		}
	}
</script>

I hope this helps anyone who still wants to use this wonderful library, without waiting for the new version.
