Conditional unobtrusive validation

Conditional unobtrusive validation - javascript

I have 5 or so fields that will be hidden or shown based on the value of a drop down list; however, if they are visible, I need them to be required.
Is there a way to dynamically turn on/off unobtrusive validation for these fields?
Here is some code:
<div class="row">
<div class="col-md-6">
<div class="form-group">
<label class="col-md-4 control-label">Routing Number</label>
<div class="col-md-8">
<input id="RoutingNumber" asp-for="org.RoutingNumber" class="form-control " autocomplete="off" />
<span asp-validation-for="org.RoutingNumber" class="text-danger"></span>
</div>
</div>
</div>
<div class="col-md-6">
<div class="form-group">
<label class="col-md-3 control-label">Account Holder Name</label>
<div class="col-md-9">
<input id="AccountHolderName" asp-for="org.AccountHolderName" class="form-control " autocomplete="off" />
<span asp-validation-for="org.AccountHolderName" class="text-danger"></span>
</div>
</div>
</div>
</div>
I would need these fields to be required, ONLY IF a separate drop down list had a certain value

$('input', newForm).val('');
$('owner').append(newForm);
});
});
</script>
How do I fix the code in order to achieve the image in number 1 ?

try this
<div class="row">
<div class="col-sm-6"> Text</div>
<div class="col-sm-6"> Text</div>
</div>
you need to apply this format then design will be properly according your desirable.

Try this way. Always use bootstrap col class inside row class then it will not cause unexpected result.
<div class="row">
<div class="col-md-12"></div>
<div class="col-md-6"></div>
<div class="col-md-6"></div>
</div>

Angular ng-if hiding the elements without any condition on them

I have just began working in angular after months of working on VueJs. I am facing a confusing problem here.
<div class="form-group">
<label class="col-sm-3 control-label">ABS</label>
<div class="col-sm-6">
<input type="text" ng-model="absTarget" class="form-control" placeholder="Set Target" />
</div>
</div>
<div class="form-group" ng-if="SelectedTask.location">
<label class="col-sm-3 control-label">Location</label>
<div ng-dropdown-multiselect="" options="example10data" selected-model="absLocation" checkboxes="true" extra-settings="setting1" />
</div>
<br />
<div class="form-group">
<label class="col-sm-3 control-label">Seven Star</label>
<div class="col-sm-6">
<input type="text" ng-model="ssTarget" class="form-control" placeholder="Set Target" />
</div>
</div>
<div class="form-group" ng-if="SelectedTask.location">
<label class="col-sm-3 control-label">Location</label>
<div ng-dropdown-multiselect="" options="example10data" selected-model="ssLocation" checkboxes="true" extra-settings="setting1" />
</div>
<div class="form-group">
<label class="col-sm-3 control-label">DEN</label>
<div class="col-sm-6">
<input type="text" ng-model="denTarget" class="form-control" placeholder="Set Target" />
</div>
</div>
<div class="form-group" ng-if="SelectedTask.location">
<label class="col-sm-3 control-label">Location</label>
<div ng-dropdown-multiselect="" options="example10data" selected-model="denLocation" checkboxes="true" extra-settings="setting1" />
</div>
This is my selected task object :
{"name":"SMS report","location":false}
So basically I have to show the 2nd,4th and 6th elements only when SelectedTask.location is true.
The problem is whenever SelectedTask.location equals false, then only 1st div element is visible, rest all becomes hidden

Self-closing <div> tag may not be supported by your parser. See here.
So the inner div of the first element isn't closed where you think it does. Which leaves the first element's outer div applied to all the following elements. Quick solution would be manually close all the inner divs.
<div class="form-group" ng-if="SelectedTask.location">
<label class="col-sm-3 control-label">Location</label>
<div ng-dropdown-multiselect="" options="example10data" selected-model="absLocation" checkboxes="true" extra-settings="setting1"></div>
</div>

add label next to input text form

i just want make some added text next to my input.
im using code igniter, here is my view code.
<div class="form-group" >
<label for="repbbpin" class="col-sm-2 text-left">Tinggi Badan :</label>
<div class="col-sm-5 text-left">
<span ><input type="text" class="form-control" onchange="update_data()" name="tinggi_badan" value="<?=#$registration->tinggi_badan?>" > cm</span>
</div>
</div>
the top code result "cm" is below the input text.
it will be good if just using additional inline code.
the result i want is like this |---input text---|cm

Try using input-addon with input-group
<div class="form-group">
<label for="repbbpin" class="col-sm-2 text-left">Tinggi Badan :</label>
<div class="col-sm-5 text-left">
<div class="input-group">
<input type="text" class="form-control" onchange="update_data()" name="tinggi_badan" placeHolder="input text" ><span class="input-group-addon"> cm</span>
</div>
</div>

Disable textbox inside an AngularJS Dynamic form

I need to disable the textbox inside my angularJS dynamic form after I clicked the button. my code seems to be working fine if I am going to disable textbox outside the dynamic form but when I get the ID of the textbox inside the dynamic form it is not working. What could be the problem.
$scope.copyText = function () {
document.getElementById('copyText').disabled=true;
document.getElementById('bName').disabled=true;
document.getElementById('pName').disabled=true;
// $('#bName').attr('disabled', true);
//alert('#bName');
$scope.LanguageFormData.language = [
{ bName: document.getElementById('brandName').value, pName: document.getElementById('prodName').value, pNameSub: document.getElementById('prodNameSub').value, lFeature: document.getElementById('pfeatureNew').value, lIngredient: document.getElementById('pingredientNew').value, lInstruction: document.getElementById('pinstructionNew').value, languageCat: null }
];
My View looks like this
<div class="col-md-12" class="pull-right" >
<button class="btn btn-primary pull-right" type="button" ng-click="copyText()" id="copyText" value="">COPY</button>
</div>
</div>
<div id="web" ng-repeat="languageItem in LanguageFormData.language">
<div class="row col-xs-12">
<div class="col-xs-6">
<br/><br/>
<div class="form-group">
<label class="col-md-6 control-label">Brand Name: </label>
<div class="col-md-6">
<input type="text" class="form-control" ng-required="true" name="bName" id="bName" class="form-control" ng-model="languageItem.bName" required/>
</div>
</div><br/><br/><br/>
<div class="form-group">
<label class="col-md-6 control-label">Product Name: </label>
<div class="col-md-6">
<input type="text" class="form-control" name="pName" ng-required="true" id="pName" ng-model="languageItem.pName" required/>
</div>
</div><br/><br/><br/>

Why not use ng-disabled. You need to change $scope.disableThis=false; back to false to re-enable the text somewhere else inside the controller code.
$scope.copyText = function () {
$scope.disableThis=true;
$scope.LanguageFormData.language = [
{ bName: document.getElementById('brandName').value, pName: document.getElementById('prodName').value, pNameSub: document.getElementById('prodNameSub').value, lFeature: document.getElementById('pfeatureNew').value, lIngredient: document.getElementById('pingredientNew').value, lInstruction: document.getElementById('pinstructionNew').value, languageCat: null }
];
Suggestions:
I have some doubts on the above code, you can just use the $scope.LanguageFormData.language as is, since you are using ng-model in the input fields, the data of the variable is updated dynamically, you can check this by {{LanguageFormData.language}} printing the output in the HTML
HTML:
<div class="col-md-12" class="pull-right" >
<button class="btn btn-primary pull-right" type="button" ng-click="copyText()" id="copyText" ng-disabled="disableThis" value="">COPY</button>
</div>
</div>
<div id="web" ng-repeat="languageItem in LanguageFormData.language">
<div class="row col-xs-12">
<div class="col-xs-6">
<br/><br/>
<div class="form-group">
<label class="col-md-6 control-label">Brand Name: </label>
<div class="col-md-6">
<input type="text" class="form-control" ng-required="true" name="bName" id="bName" ng-disabled="disableThis" class="form-control" ng-model="languageItem.bName" required/>
</div>
</div><br/><br/><br/>
<div class="form-group">
<label class="col-md-6 control-label">Product Name: </label>
<div class="col-md-6">
<input type="text" class="form-control" name="pName" ng-required="true" id="pName" ng-model="languageItem.pName" ng-disabled="disableThis" required/>
</div>
</div><br/><br/><br/>
Suggestions:
It would be good if you restrict the ID for one particular element alone, its a good practice to follow in general!

Bootstrap 4 Form Validation

I'm a beginner with bootstrap and I have seen a lot of bootstrap 3 form validation plugins etc, but I haven't found any for bootstrap 4.
I'm trying to validate multiple forms, and here is my code:

I have tried to modify existing js, but I had no luck.
Here is the rendered form:
jsfiddle of the form

First I solved my issue with an external library like Jonathan Dion suggested. But recently I came across this :
Bootstrap v4.0 introduced their own form validation that you can still pair with backend php validation. From the Doc :
<form class="needs-validation" novalidate>
<div class="form-row">
<div class="col-md-4 mb-3">
<label for="validationCustom01">First name</label>
<input type="text" class="form-control" id="validationCustom01" placeholder="First name" value="Mark" required>
<div class="valid-feedback">
Looks good!
</div>
<div class="invalid-feedback">
Doesn't look good!
</div>
</div>
</div>
</div>
Then using JS :
<script>
// Example starter JavaScript for disabling form submissions if there are invalid fields
(function() {
'use strict';
window.addEventListener('load', function() {
// Fetch all the forms we want to apply custom Bootstrap validation styles to
var forms = document.getElementsByClassName('needs-validation');
// Loop over them and prevent submission
var validation = Array.prototype.filter.call(forms, function(form) {
form.addEventListener('submit', function(event) {
if (form.checkValidity() === false) {
event.preventDefault();
event.stopPropagation();
}
form.classList.add('was-validated');
}, false);
});
}, false);
})();
</script>
This provides input border colorating and displays the valid / invalid feedback blocks according to the given pattern or properties. It is applied via CSS’s two pseudo-classes, :invalid and :valid. It applies to <input>, <select>, and <textarea> elements.

Update 2020 - Bootstrap 4.4.x
Here's another option (modern JS) if you want to validate each input one at a time (live or real-time) instead of waiting for the entire form to be submitted...
(function() {
'use strict';
window.addEventListener('load', function() {
// fetch all the forms we want to apply custom style
var inputs = document.getElementsByClassName('form-control')
// loop over each input and watch blur event
var validation = Array.prototype.filter.call(inputs, function(input) {
input.addEventListener('blur', function(event) {
// reset
input.classList.remove('is-invalid')
input.classList.remove('is-valid')
if (input.checkValidity() === false) {
input.classList.add('is-invalid')
}
else {
input.classList.add('is-valid')
}
}, false);
});
}, false);
})()
<form class="container" novalidate="" action="/echo" method="POST" id="myForm">
<div class="form-group">
<label class="form-control-label" for="input1">Enter some input</label>
<input type="text" class="form-control" name="input1" id="input1"
autocomplete="no" required>
<div class="valid-feedback">Success! You've done it.</div>
<div class="invalid-feedback">No, you missed this one.</div>
</div>
<div class="form-group">
<label class="form-control-label" for="input2">Enter password</label>
<input type="text" class="form-control"
pattern="^(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{6,}$"
autocomplete="no" name="input2" id="input2">
<div class="valid-feedback">Nice! You got this one!</div>
<div class="invalid-feedback">At least 6 chars: 1 uppercase, 1 lowercase and numeric</div>
</div>
<div>
<button type="submit" class="btn btn-secondary" id="btnSubmit">Submit</button>
</div>
</form>

You can use any library available on the web. You may try jqueryvalidation. It's pretty easy to use, just read the documentation.
Add the required attribute on your input and jqueryvalidation will do the job. For styling, you can add your own CSS and make it look like bootstrap.
Hopes it help
$(document).ready(function(){
$('#contact_form').validate()
})
Demo

I found a simpler and a bit more modern way to implement Bootstrap 4 JS Form validation:
Note: Keep in mind that each <form> element must have the novalidate attribute and at the same time, each <input> element in it must have the required attribute.
// Upon load..
window.addEventListener('load', () => {
// Grab all the forms
var forms = document.getElementsByClassName('needs-validation');
// Iterate over each one
for (let form of forms) {
// Add a 'submit' event listener on each one
form.addEventListener('submit', (evt) => {
// check if the form input elements have the 'required' attribute
if (!form.checkValidity()) {
evt.preventDefault();
evt.stopPropagation();
console.log('Bootstrap will handle incomplete form fields');
} else {
// Since form is now valid, prevent default behavior..
evt.preventDefault();
console.info('All form fields are now valid...');
}
form.classList.add('was-validated');
});
}
});
<!-- Load necessary libraries -->
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
<!-- Add form -->
<div class="container" style="padding-top: 40px;">
<form class="student-search needs-validation" novalidate>
<div class="form-row">
<div class="form-group col-6">
<label for="input-name-search" class="sr-only">Name</label>
<input type="text" class="form-control" id="input-name-search" placeholder="Name" required>
<div class="valid-feedback">Looks good!</div>
<div class="invalid-feedback">Enter a name please.</div>
</div>
<div class="col-6">
<button id="btn-search" type="submit" class="btn btn-success btn-block">Search student</button>
</div>
</div>
</form>
</div>

I just figured out the reason my code wasn't validating: I didn't have a submit button to trigger the validation. Make sure to have it.
<button type="submit" class="btn btn-primary">Save</button>

There's no real need for a library here, you can use the native reportValidation() method: MDN. You can call it on individual inputs or on the entire form itself.
