JQuery Validate Input on Button Toggle

I'm using Jquery Validate in my web form. I have an empty input, however the input is populated dynamically with text on the click of a button. Validation doesn't seem to work when I do this.
when the input is empty, on submit validation works (input turns red).
when input is populated dynamically, it stays red, it should turn green
My code is below and here's a fiddle;
In the fiddle, click submit when the input is empty, then toggle the button to No - the input should change to green without having to submit the form again.
HTML
<p>Does this item have an inventory number?</p>
<p>
<form id="myForm" method="post">
<input type="checkbox" class="input-large" value='1' name="btn" id="btn">
<div class="control-group">
<div class="controls">
<div class="input-prepend">
<input type="text" class="input-large" id="type" name="type" placeholder="Inventory Number">
</div>
</div>
</div>
<input type="submit" class="submit" value="Submit">
</form>
Jquery
$(function() {
$('#btn').bootstrapToggle({
on: 'No',
off: 'Yes',
onstyle: 'danger'
});
})
$("#myForm").validate({
rules: {
type: {
required: true,
minlength: 2
}
},
highlight: function(label) {
$(label).closest('.control-group').addClass('error');
},
unhighlight: function(label) {
$(label).closest('.control-group').addClass('success');
},
});
$("#btn").on("change", function() {
if ($(this).prop('checked') == true) {
$("#type").attr("readonly", "true");
$("#type").val("Personal Item");
$("#type").rules("remove", "number minlength maxlength");
}
if ($(this).prop('checked') == false) {
$("#type").removeAttr("readonly");
$("#type").val("");
$("#type").rules("add", {
required: true,
minlength: 5,
maxlength: 6
});
}
});

You use some custom highlight and unhighlight on the control-group.
Just add this to the checked==true condition:
$("#type").closest('.control-group').removeClass("error").addClass("valid");
$("#type").next(".error").remove();
Since the rule is removed, it is not re-validated...

Unable to validate bootstrap

I have the following jquery code
$().ready(function){
$("#Form").validate({
rules:{
DL:{
minlength:2
}
}
});
}
message:{
DL:{
minlength:"DL should be of at least 5";
}
}
The validation required is that the field DL should have length of 5.
The html code is below
<div class="form-group">
<label for="exampleInputText">Driving License Number</label><input
type="text" class="form-control" id="DL" required>
</div>
But the page does not seem to validate, after clicking a button, instead of showing message the page just scrolls upwards.

Here is your solution
https://jsfiddle.net/geradrum/far1fj1n/
All the code have syntax errors.
And the $() should be $(document)

The main problem is that the rules object looks for the element's name and you were using the id of the element.
index.html
<form id="FORM">
<div class="form-group">
<label for="exampleInputText">Driving License Number</label><input type="text" class="form-control" name="DL" required>
</div>
<input type="submit" value="Validate!">
</form>
app.js
$(document).ready(function(){
$( "#FORM" ).validate({
rules: {
DL: {
required: true,
minlength: 5
}
},
messages: {
DL: "DL should be of at least 5"
}
});
});

jQuery validation plugin submits even if validation errors occur

I am trying to validate a bootstrap form with jQuery.
var formSubmit = $("#dl-mg-form-publish").validate({
rules: {
'dl-mg-input-youtube': {
required: true,
url:true,
},
'dl-mg-input-title': {
required: true,
minlength: 6 });
I am trying to validate this:
var videoInformation = {
youtubeID: $('#dl-mg-input-youtube').val(),
title: $('#dl-mg-input-title').val(), }
This is my html:
<form class="form-horizontal dl-mg-form-horizontal" id="dl-mg-form-publish" action="#">
<div class="form-group">
<label for="dl-mg-input-youtube" class="control-label col-xs-2">YouTube Video ID:</label>
<div class="col-xs-6">
<input type="url" class="form-control" id="dl-mg-input-youtube" name="dl-mg-input-youtube" placeholder="Youtube ID">
</div>
</div>
<div class="form-group">
<label for="dl-mg-input-title" class="control-label col-xs-2">Video Title:</label>
<div class="col-xs-6">
<input type="text" class="form-control" id="dl-mg-input-title" name="dl-mg-input-title" placeholder="Video Title">
</div>
</div>
I am new at programming I don't know how to validate first and then submit. I tried using a .click handler but it submits the fields with errors anyway. Please help!

Before submitting your form you need to validate the form. You can do this inside the click event like:
$("#target").click(function () {
// Validate the form first
if (!$("#dl-mg-form-publish").valid()) return false;
// Your form is valid, so continue with you submit logic..
});
More info here: .valid()
EDIT:
Disable auto validation on keypress
Use this options for the validate() method:
$("#dl-mg-form-publish").validate({
onfocusout: false,
onkeyup: false,
// other options here
})

How to submit form with Bootstrap Validator

I am using http://bootstrapvalidator.com/ with visual studio in bootstrap asp.net project.
Problem I am having that I can never get validate button to actually validate like it does in examples, it validates fine when I start typing into textbox, but never validates when I click on button following examples.
Another issue is I don't know how to call my c# method which will get value from textbox after validation was successful, I can call my method on button click, but I want it to happen just after validation was successful .
What I am looking for is simple example how to make submit button validate fields and then call my c# method which will read values from inputs.
I been unable find even single example online , and I dont know much about javascript.
Here is some testing code I have
<div class="form-group" id="nameEmail2">
<div class="form-group">
<label for="inputContactName" class="col-sm-5 control-label">Contact Name </label>
<div class="col-sm-7">
<input type="text" class="form-control" name="fullName1" id="TextBox1" placeholder="Contact Name" maxlength="50"/>
</div>
</div>
<div class="form-group">
<label for="inputContactEmail" class="col-sm-5 control-label">Contact Email <b>*</b></label>
<div class="col-sm-7">
<input type="text" class="form-control" name="email1" id="TextBox2" placeholder="Contact Email" maxlength="50"/>
</div>
</div>
<div class="form-group">
<div class="col-sm-5 col-sm-offset-3">
<button type="submit" runat="server" onserverclick="submitValidate" class="btn btn-default">Validate</button>
</div>
</div>
</div>
<script type="text/javascript">
$(function () {
$('#nameEmail2').bootstrapValidator({
feedbackIcons: {
valid: 'glyphicon glyphicon-ok',
invalid: 'glyphicon glyphicon-remove',
validating: 'glyphicon glyphicon-refresh'
},
fields: {
fullName1: {
validators: {
notEmpty: {
// enabled is true, by default
message: 'The full name is required and cannot be empty'
},
stringLength: {
enabled: true,
min: 8,
max: 40,
message: 'The full name must be more than 8 and less than 40 characters long'
},
regexp: {
enabled: false,
regexp: /^[a-zA-Z\s]+$/,
message: 'The full name can only consist of alphabetical, number, and space'
}
}
},
email1: {
validators: {
emailAddress: {
message: 'The value is not a valid email address'
}
}
}
}
});
});
</script>
I have removed most of asp objects and almost nothing runs at server any more, but that didnt help much here is my codebehind method
protected void submitValidate(object sender, EventArgs e)
{
string contactName = Request.Form["fullName1"];
string email = Request.Form["email1"];
System.Diagnostics.Debug.Write("test",email);
}

Trying to get jquery validator to work on specific button click

I am trying to get the jquery validator to run on the specific submit button not on all buttons.
<form id="incidentform" action="/emplincidata.php" method="get">
<input type="submit" class="button" name="updateincidentButton" value="Update Incident"/>
<input type="button" class="button" name="cancelincidentButton" value="Cancel Incident"/>
<br />
<div class="makescroll" id="bysuper">
<div class="incident">
<label class="title">TO BE COMPLETED BY THE SUPERVISOR</label><br />
<div>
<label class="eighth" for="incidate">Incident Date</label>
<input type="text" id="incidate" name="incidate" class="datepick" />
<label class="eighth" for="incidtime">Incident Time</label>
<input type="text" id="incidtime" name="incidtime" class="timeinput" />
<label class="eighth" for="shift">Shift</label>
<select id="shift" name="shift">
<option selected="selected"></option>
<option>Day</option>
<option>Evening</option>
<option>Night</option>
</select>
</div>
</div>
</div>
</form>
Here is the javascript. This code does not work when I have the submit catptured. I also tried click here and it failed.
$(function(){
$("#updateincidentButton").submit(function(){
$("form").validate({
rules: {
incidate: "required",
incitime: "required",
shift: "required"
}
})
})
})

You have not given Id selector to your submit button. so please give Id selector as below:
<input type="submit" class="button" id="updateincidentButton" name="updateincidentButton" value="Update Incident"/>

Please try as shown below:-
$(document).ready(function(){
/* Bind Validate() to Form */
$("#incidentform").validate({
rules: {
incidate: "required",
incitime: "required",
shift: "required"
}
})
/* Bind Click() to Button*/
$("input[name=updateincidentButton]").click(function () {
if ($(#incidentform).valid()) {
// post stuffs
}
return false;
});
});

Try this:
$(document).ready(function(){
/* Bind Validate() to Form */
$("#incidentform").validate({
rules: {
incidate: "required",
incitime: "required",
shift: "required"
},
submitHandler :function() {
// DO STUFF HERE WHEN EVERYTHING IS VALIDATED e.g submit form
alert('VALID');
}
})
});
Fiddle: http://jsfiddle.net/ZKge8/
Just scroll to the bottom of the page to skip the validate plugin script.
