It has automated listener to monitor every changes on form.

Note:

1. Validation take place between tags, so need to specify the ID
   of the Form or any other tags.

<formid="form2submit"></form> // Preferred
<divid=form2submit></div> // Not-Preferred.

For General Input Validation

2. Input Fields should specify the type of validation.

<formmethod="post" id="form2submit" novalidate><div><label>Only Alpha</label><inputtype="text" data-allow="onlyAlpha" name="alpha"
data-message="<b style='color:green'>This field is required.</b>" required></div><div><label>String</label><inputtype="text" data-allow="string" data-message="This also required." data-allowSpecial="+-" name="string"
required></div><div><label>Pattern</label><inputtype="text" pattern="^[0-5]+$" data-allowSpecial="/-" name="pattern"></div><div><label>Number</label><inputtype="number" name="number" required></div><div><label>Min Validator</label><inputtype="text" name="myNumber" min="5" max="10" required></div><div><label>Email Validator</label><inputtype="email" name="email" required></div><div><labelfor="file">File</label><inputtype="file" requiredclass="form-control" id="file" data-extensions="png,jpeg,jpg" name="file"></div><div><label>Password</label><inputtype="password" name="password" data-check="repassword" id="password" required></div><div><label>Password</label><inputtype="password" name="password" data-check="repassword" id="password" required></div><div><label>List</label><selectname="list" required><optionvalue="item1">Item1</option><optionvalue="item2">Item2</option><optionvalue="item3">Item3</option></select></div><div><label>Description</label><textarearequiredname="desc"></textarea></div><div><inputtype="submit" value="Submit"></div></form>

3. In form use novalidate to avoid browser interuptions.

   <formmethod="POST/GET/PUT/PATCH/DELETE" action="PATH-TO-HANDLE" id="form2submit" novalidate> ...
   ...
   </form>

Sample

// For Native & ES6 Javascript.varmyform=newjsValidator().init({form: 'form2submit',// #idforceFilter: true,message: {required: 'This field is required !',min: '<br><span style="color: red;">This field is less then the limit</span>',max: 'This field is exceeds the limit',password: 'Password doesn\'t match !',email: 'Invalid Email found !',file: 'Invalid File format given'}});

It Will listen the Submit event Automatically and initiating the validation checks. And based on response, it will allow to submit or throw messages.
