How to empty ajax loaded form? - javascript

How can we empty a ajax loaded form using pure JavaScript or jQuery.
I have tried document.forms[0].reset(); and $('#new-staff-form')[0].reset(); both didn't work it returns undefined.
Update
<div class="box col-md-12 new-staff">
<form id="new-staff-form" method="post">
<div class="row">
<div class="col-md-6">
<label for="f_name">First Name</label>
<input type="text" name="f_name" placeholder="First name"/>
</div>
<div class="col-md-6">
<label for="l_name">Last Name</label>
<input type="text" name="l_name" placeholder="Last name"/>
</div>
</div>
<div class="row">
<div class="col-md-6">
<label for="user_name">User name</label>
<input id="user_name" type="text" name="user_name" placeholder="User name"/>
</div>
<div class="col-md-6">
<button id="user-avail" class="btn btn-primary">Check available</button>
</div>
</div>
<div class="row">
<div class="col-md-12">
<button class="btn btn-primary pull-left">Save</button>
</div>
</div>
</form>
</div>
Javascript:
$('#new-item').click(function(){ // works fine until I load new html form using ajax with same ids and class
$('#new-staff-form')[0].reset();
$('.new-staff').slideToggle(); // show new form
});
$('.edit-item').click(function(){ // ajax call this loads everything correctly
var id = $(this).data('staf_id'); //item to delete
$.ajax({
url:url_view_staff+id,
type:'get'
}).done(function(data){
edit_item_id = id;
$('.new-staff').html(data).slideDown();
}).fail(function(data){
$('#errors').html(data.responseText);
$('.valid-error').slideDown();
});
});

JavaScript:
document.getElementById("myForm").reset();
Jquery :
$('#form_id')[0].reset();
Make sure your form id is valid.

FIDDLE
$('#configreset').click(function(){
$('#configform')[0].reset();
});

checkValidity() not showing any html5 error notifications when fields are empty and posting with Ajax

I have a form that posts using Ajax, I also want to set an HTML5 required attribute on some input fields, but this stops working as expected with Ajax.
So I did the following:
$("body").on("click",".register-button",function(e){
e.preventDefault();
if($('#registerform')[0].checkValidity()){
registerform = $(".register-form").serialize();
$.ajax({
type:'post',
url:"includes/registreren.php",
data:({registerform: registerform}),
success:function(data){
var content = $( $.parseHTML(data) );
$( "#registerresult" ).empty().append( content );
}
});
}else{
}
});
This way the form is not posted when empty, but I also don't get any notifications that fields are empty like I would get when only using HTML to post.
I also tried logging the validity like so:
$("body").on("click",".register-button",function(e){
e.preventDefault();
$check = $('#registerform')[0].checkValidity();
console.log($check);
registerform = $(".register-form").serialize();
$.ajax({
type:'post',
url:"includes/registreren.php",
data:({registerform: registerform}),
success:function(data){
var content = $( $.parseHTML(data) );
$( "#registerresult" ).empty().append( content );
}
});
});
Which shows false in my console when empty. So the code works, why are the HTML5 notifications not shown? I remember doing something similar in the past and I didn't have to add any custom error messages then, it just worked.
This is my HTML markup:
<form id="registerform" class="register-form" method="post">
<div class="row">
<div class="col-md-6">
<input type="text" name="voornaam" placeholder="Voornaam" required>
</div>
<div class="col-md-6">
<input type="text" name="achternaam" placeholder="Achternaam" required>
</div>
<div class="col-md-12">
<input type="text" name="bedrijf" placeholder="Bedrijfsnaam (optioneel)">
</div>
<div class="col-md-6">
<input type="text" name="telefoon" placeholder="Telefoonnummer" required>
</div>
<div class="col-md-6">
<input type="text" name="email" placeholder="E-mail" required>
</div>
<div class="col-md-3">
<input type="text" name="huisnummer" id="billing_streetnumber" placeholder="Huisnummer" required>
</div>
<div class="col-md-3">
<input type="text" name="tussenvoegsel" placeholder="Tussenvoegsel" required>
</div>
<div class="col-md-6">
<input type="text" name="postcode" id="billing_postcode" placeholder="Postcode" required>
</div>
<div id="postcoderesult" class="col-lg-12">
<div class="row">
<div class="col-md-6">
<input type="text" name="straat" placeholder="Straatnaam" readonly required>
</div>
<div class="col-md-6">
<input type="text" name="woonplaats" placeholder="Woonplaats" readonly required>
</div>
</div>
</div>
<div class="col-md-6">
<input type="password" name="password" placeholder="Wachtwoord (minimaal 6 tekens)" required>
</div>
<div class="col-md-6">
<input type="password" name="confirmpassword"placeholder="Herhaal wachtwoord" required>
</div>
<div id="registerresult">
</div>
</div>
<button type="button" name="submit" class="register-button">Account aanmaken</button>
</form>
What am I missing?

Jquery Valid() function only apply on 1st element

I am intend to use javascript to submit the form. Before I want to submit the form, I need to validate my form.
The following is my code :
alert("OP Please edit me to add the validation script code, cdn link or something. Add code that triggers the validation.");
function validateForm1() {
$("#addMapForm").validate();
$('#addMapForm').valid();
console.log($('#addMapForm').valid());
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.19.0/jquery.validate.min.js"></script>
<form enctype="multipart/form-data" action="/Admin/AddMap" method="post" id="addMapForm">
<div>
<br />
<br />
<div class="col-md-12">
<div class="form-group">
<label>Location Name *</label>
<input class="form-control" required />
</div>
</div>
<div class="col-md-12">
<div class="form-group">
<label>Unit/ Floor Number</label>
<input class="form-control" />
</div>
</div>
<div class="col-md-12">
<div class="form-group">
<label>Address*</label>
<textarea class="form-control" style="height:100px" required></textarea>
</div>
</div>
<div class="col-md-12">
<div class="form-group">
<label>Town/ City *</label>
<input class="form-control" required />
</div>
</div>
<div class="col-md-12">
<div class="form-group">
<label>Zip Code*</label>
<input class="form-control" required/>
</div>
</div>
</div>
</form>
You are missing names on the inputs. A form will only submit named controls and validation plugin won't validate anything without a name
The required fields work fine once you add them
$("#addMapForm").validate();
$("#addMapForm").valid();

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.19.0/jquery.validate.min.js"></script>

<label>Location Name *</label>
<input name="location" class="form-control" required />
</div>
</div>
<div class="col-md-12">
<div class="form-group">

</div>
</div>
<div class="col-md-12">
<div class="form-group">

</div>
<div class="col-md-12">
<div class="form-group">
<label>Zip Code*</label>
<input name="zip" class="form-control" required/>
</div>
</div>
</div>
<button>Submit</button>
</form>
I assume you are using this: https://jqueryvalidation.org/validate/
Have you implemented the rules of validation for other elements?
rules (default: rules are read from markup (classes, attributes, data))
So either you have those defined in HTML or you need to define them inside validate function called before you called .valid().
Here is an examle:
$("#myform").validate({
rules: {
// simple rule, converted to {required:true}
name: "required",
// compound rule
email: {
required: true,
email: true
}
}
});
In short for more precise help we need all the relevant code or fiddle, plunker a demo showing the example of the problem you are facing.
Try this solution.
$('.form-control').each(function() {
$(this).validate();
$(this).valid();
}
I tried to use the following js to validate all my form, however i know the following code is not the best answer, it only able to show the error message on the first input element.
I am welcome to anyone to post better answer than this.
function validateForm() {
var result = true;
$("#addMapForm").each(function () {
$(this).find(':input').each(function () {
if ($(this).valid() == false) {
result = false;
return;
}
});
});
return result;
}
I gave your form inputs some name attributes. Not sure if you added the actual code to your page, so I did so here. I added a button to trigger just for a demo. I added the simplest bit of CSS.
$("#validateme").on('click', function() {
console.log("validating");
let Validator = $("#addMapForm").validate();
Validator.form();
console.log(Validator.valid());
});
.error { color:red}

Saving dynamically added li and ul element to database using an array

I'm trying to build a User interface of an application where user could add ul and li element when clicking on add question, I successfully managed to develop the front end part here's a preview:
but the problem is when saving this to the database which is so overwhelming I'm stuck at this, is there any way to save the data to an array so I can display them with php, any idea is welcomed.
here's the jquery code:
wrapper.on("click", "button", function(e){
e.preventDefault();
var parent = $(this).parent().parent().parent().parent().parent().parent();
var parentID = $(this).attr('element-id');
var elementID = 1000000000000000000*Math.random();
parentIDs.push(elementID);
if($(this).attr('class') == "add_field_button btn btn-success"){
if(parent.find('ul').length){
parent.find('ul').first().append(`
<li>
<div class="panelcb white-box">
<div class="form-horizontal form-material">

Thanks is advance.
Well...
If the whole user-interative-area, I'd call a playground, can be put inside a container:
<div id='playground'>
.. all the ul's and li's..
</div>
And if you've got a form or something else:
<form action='/' id='form-playground' method='post'>
<textarea id='playground-container' name='playground' class='hidden'>
</textarea>
<input type='submit' value='Save My Playground'>
</form>
Then on submit you can copy the contents of the the playground to a hidden textarea:
$(document).ready(function () {
$('#form-playground').on('submit', function () {
$('#playground-container').html($('#playground').html());
return true;
});
});
Or perhaps an AJAX post:
$.post( PostUrl, { playground: $('#playground').html() } );

how to call a js function in html

enter code hereI have an issue with my html. I am trying to save an input to my localstorage. For some reason, whenever I inspect my website I don't see the word I typed in my field. In other words it is not loading the input to my localstorage.
I am new to html and javascript and I am hoping you guys can help me out. I'm providing a picture to demostrate what I am trying to approach.
function getInput(){
var nameInput = document.getElementById('inputName').value;
localStorage.setItem('text', dataInput);
var dateInput = document.getElementById( 'inputDate').value;
localStorage.setItem('text1', dateInput);
}
<form class="form-horizontal">

Post data to hidden iframe then show it in the same page wtihout reload

I'm a little newbie with jQuery, ajax and JavaScript. I need a little help to find out how to post data to a hidden iframe and then display it with the same button.
Here is what I've tried so far:
<form id="testform" name="testform" class="form-horizontal" action="testing/index.php" method="post" target="mydata">
<div class="form-group">
<div class="col-sm-6 col-sm-offset-3">
<input class="form-control" placeholder="please enter test name" name="test-input">
</div>
</div>
<div class="form-group">
<div class="col-sm-12">
<button type="submit" class="btn btn-primary" id="testit">I want to test!</button>
</div>
</div>
</form>
<div class="row">
<div class="col-md-12" id="target">
<script>
$(document).ready(function() {
$('#testform').on('submit', function() {
$("#target").show();
});
$("#target").hide();
});
$("#target").html('<object name="mydata" data="http://testurl.com/testing"></object>');
</script>
</div>
</div>
Thank you for your help.
What you should do, if you really need to do it this way is:
<form id="testform" name="testform" class="form-horizontal" action="testing/index.php" method="post" target="mydata">
<div class="form-group">
<div class="col-sm-6 col-sm-offset-3">
<input class="form-control" placeholder="please enter test name" name="test-input">
</div>
</div>
<div class="form-group">
<div class="col-sm-12">
<button type="submit" class="btn btn-primary" id="testit">I want to test!</button>
</div>
</div>
</form>
<iframe id="mydata" style="border:0; height:0;"></iframe>
<script>
$(document).ready(function() {
$('#testform').on('submit', function() {
$("#mydata").css("height", 300);
});
});
</script>
How ever I do recomend you to have a look at jQuery's $.post() documentation and .serialize() documentation. you could to something like this instead:
<form id="testform" name="testform" class="form-horizontal">
<div class="form-group">
<div class="col-sm-6 col-sm-offset-3">
<input class="form-control" placeholder="please enter test name" name="test-input">
</div>
</div>
<div class="form-group">
<div class="col-sm-12">
<button type="submit" class="btn btn-primary" id="testit">I want to test!</button>
</div>
</div>
</form>
<div id="succesResult"></div>
<script>
$(document).read((function(){
$('#testform').on('submit', function() {
var data = $( this ).serialize();
$.post("http://target.url", data, function(resultFromServer){
//success callback
$("#succesResult").html(resultFromServer); <--result could be html
})
});
}
</script>
