I have normal form which looks like this(You can ignore the inside fields as they are all input fields):
<div class="col-md-12" style="float: none;">
<div class="form-group row">
<div class="col-md-6" style="border: 2px solid #efefef;">
<div class="card-body">
<div class="col-md-12">

Due to some reasons,I have not wrapped all these fields inside <form></form> tag but when I perform the submit operation by clicking the
<button type="submit" id="sub" class="btn btn-success pull-right">Submit</button>,it is not performing html5 validation. This on click function is trigerred and it is getting posted.How to validate html5 features without using <form> tag?
$( "#sub" ).click(function() {
alert( "Handler for .click() called." );
//ajax code to submit
});

submitworks forformonly. Mean it submits the parent form. if you do not have any form,submitwill not work. as you are saying for some reason in html you don't want to wrap informthen using javascript wrap it. but to trigger the form submit you must haveform, yes if you want to check thevalidationon each field individual then of course you can refer the above link by @Cue – Deepak Sharma Commented Jan 16, 2019 at 5:03

Reset to default 5You can use the constraint validation API for that. Refer this. Example-
var emailId = document.getElementById("id");
var valid = emailId . checkValidity();
if (valid) {
//perform operation
}
Use element.reportValidity() to both validate AND show the popup if it fails.
https://developer.mozilla/en-US/docs/Web/API/HTMLInputElement/reportValidity
Form validations will be triggered by buttons inside a form automatically.
But for manual triggering you can use checkValidity.
Here's a sample bin for that case:

You probably shouldn't be doing HTML5 validation without the <form> element. Here's more literature on forms
