JQuery input messages - javascript

I have a form with inputs. The first input needs to be filled out before the second input.
If the user clicks on input 2 first they get a message saying to fill the other input first. Now I want to make it so that after the message pops up, if the user then fills out input one the message disappears.
My codepen.
I tried adding an onchange function but that doesn't seem to work.
$('body').on('focus', '.clickable', function() {
if (!$('.look').val().length) {
$(this).siblings('p').text('Please select Type first')
}
});
$('body').on('change', '.look', function() {
if ($('.look').val().length) {
$(this).siblings('p').text('')
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<div>
Input-1:<br>
<input type="text" name="first" id="one" class="look"><br> Input-2:
<br>
<input class="clickable" type="text" name="second" id="two">
<p class="warning"></p>
</div>
</form>

on change called when you leave the input, your code works when leaving the input, also you can change the "on change" by keyup to see the changes whitout leaving the input
codepen : https://codepen.io/anon/pen/QOzKwQ

You could use keyup as your event instead of change. Change needs to wait for you to click away from the input (blur).
$( 'body').on('focus','.clickable',function() {
if (!$('.look').val().length) {
$(this).siblings('p').text('Please select Type first')
}
});
$( 'body').on('keyup','.look',function() {
if ($('.look').val().length) {
$(this).siblings('p').text('')
}
});

Use .on("change keyup paste"...)
to detect immediate changes to the text-field
$( 'body').on('focus','.clickable',function() {
$('.look').on("change keyup paste", function(){
$(this).siblings('p').text('')
});
if (!$('.look').val().length) {
$(this).siblings('p').text('Please select Type first')
}
});
$( 'body').on('change','.look',function() {
if ($('.look').val().length) {
$(this).siblings('p').text('')
}
});

I don't mean to change your approach but you could try disabling the field so they can't click it and then enable it once input 1 has been filled?
HTML:
<form>
<div>
Input-1:<br>
<input type="text" name="first" id="one" class="look"><br>
Input-2:<br>
<input class="clickable" type="text" name="second" id="two" >
<p class="warning"></p>
</div>
</form>
The JS:
document.getElementById("two").disabled = true;
var dis1 = document.getElementById("one");
dis1.onchange = function () {
if (this.value != "" || this.value.length > 0) {
document.getElementById("two").disabled = false;
}
}

It will be more efficient if you track the user input using input event like :
$('body').on('input', '.look', function() {
if ($('.look').val().length) {
$(this).siblings('p').text('')
}
});
Snippet:
$('body').on('focus', '.clickable', function() {
if (!$('.look').val().length) {
$(this).siblings('p').text('Please fill the first input.')
}
});
$('body').on('input', '.look', function() {
if ($('.look').val().length) {
$(this).siblings('p').text('')
}
});
.warning {
color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<div>
Input-1:<br>
<input type="text" name="first" id="one" class="look"><br> Input-2:
<br>
<input class="clickable" type="text" name="second" id="two">
<p class="warning"></p>
</div>
</form>

How do you set the text from an input to another element after clicking submit?

For example when somebody inputs text and presses submit I want the text to be displayed in an h1 tag.
<div>
<label for="message"> Message:</label>
<input type="text" id="message" name="message" class="m3">
<button id="btn1" class="butt">Ready to Send?</button>
<h1 id="test">Header</h1>
</div>
$(document).ready(function() {
$('btn1').click(function() {
$('#test').text($("#message").val());
});
});
$(document).ready(function() {
$('#btn1').click(function() {
$('#test').text($("#message").val());
//--> if you want to remove the value of the input after parsing the code, simply check if
//--> not `null` or not `undefined` by placing the selector.val() in your if conditional...
if($("#message").val()){
$("#message").val('');
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
<label for="message"> Message:</label>
<input type="text" id="message" name="message" class="m3">
<button id="btn1" class="butt">Ready to Send?</button>
<h1 id="test">Header</h1>
</div>
You did not add the # selector in JQuery for ID
$(document).ready(function() {
$('#btn1').click(function() {//<-- Make sure to add the ID selector # in Jquery
$('#test').text($("#message").val());
});
});
$(document).ready(function () {
$('#btn1').click(function (e) {
e.preventDefault();
$('#test').html($("#message").val());
});
});
This would work fine, but like #Teemu says this removes the form functionality. If you want to add a check mechanism you can use something like this:
$(document).ready(function () {
$("#message").keyup(function() {
$("#test").html($("#message").val());
});
});

jquery validation on blur on all input text

I trying to use form validation when a user leaves the text form.
this code is actually run as I wanted but, the problem is I cannot validate specific form I input. when I leave form name, the form number also showing an error before I have a chance to input on it.
How can I split the error message on every input into the global function when the user leaves the form text?
$(document).ready(function(){
$('input[type=text]').on('blur', function(){
$(this).each(function(){
nama ($('#nama').val());
no($('#nomor').val());
});
});
function nama(myname){
if(!myname){
$('<span>name cannot be empty</span>').insertAfter('#nama');
}
}
function no(mynomor){
if(!mynomor){
$('<span>number cannot be empty</span>').insertAfter('#nomor');
}
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p>name</p>
<input type="text" id='nama'>
<br>
<p>number</p>
<input type="text" id='nomor'>
You can simplify your code to achieve that hide show by using the error message span in the HTML itself and then selecting the span element based on the input element id. Something like this:
$(document).ready(function() {
$('input[type=text]').on('blur', function(e) {
var id = this.id;
if (e.target.value) {
$('#' + id + 'span').hide();
} else {
$('#' + id + 'span').show();
}
});
});
.error-span {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p>name</p>
<input type="text" id='nama'>
<span id='namaspan' class='error-span'>name cannot be empty</span>
<br>
<p>number</p>
<input type="text" id='nomor'>
<span id='nomorspan' class='error-span'>number cannot be empty</span>
I would suggest to let the error message in the HTML, but not being displayed, then when the blur events occur, you check to see if the field is empty, if it is, then get the element with the error message and show it.
I created a function that will be called by every input[type=text] when blur occurs, that function will check/validate the field
$(document).ready(function(){
$('input[type=text]').on('blur', function(){
validateField(this)
});
function validateField(field){
let value = field.value;
if (value.trim().length < 1 || value === null){
$(field).siblings(".invalid-msg").removeClass("not-error").addClass("error-show")
}else{
$(field).siblings(".invalid-msg").removeClass("error-show").addClass("not-error")
}
}
});
.error-show{
display: inline-block;
color: red;
}
.not-error{
display: none
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
<p>name</p>
<input type="text" id='nama'> <span class="not-error invalid-msg">Name can't be empty</span>
</div>
<br>
<div>
<p>number</p>
<input type="text" id='nomor'> <span class="not-error invalid-msg">Number can't be empty</span>
</div>

Track inputs and toggle class with jQuery

What I am trying to achieve is track 20 inputs, if one is filled I want to add a class to a parent div of this input, if it becomes empty after I want the class to remove itself from the parent. This code does what I want when I run it in the console, how can I improve it so it can track the inputs and toggle the class?
$('.input').each(function() {
var $input = $(this);
if ($input.val()) {
var $parent = $input.closest('.card');
$parent.addClass('colored')
}
});
You can use an event to do so. For inputs, jQuery has the input event that fires every time the value of an input changes.
$(".input").on("input", function () {
if ($(this).val().length === 0)
$(this).closest('.card').removeClass("colored");
else
$(this).closest('.card').addClass("colored");
});
Your code checks for values at the initial run. You would need to attach events copy, paste, change, keypress, keydown, keyup and input. See example:
$('input').on('copy paste keydown keyup keypress change input', function(){
var $input = $(this);
if( $input.val() == '' ){
$input.parent('.form-group').addClass('empty');
} else {
$input.parent('.form-group').removeClass('empty');
}
});
.form-group {
margin-bottom:10px;
}
.form-group.empty > input {
border:2px solid red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="form-group">
<input name="name" type="text" placeholder="name"/>
</div>
<div class="form-group">
<input name="email" type="text" placeholder="email"/>
</div>
<div class="form-group">
<input name="address" type="text" placeholder="address"/>
</div>
This is the snippet Here. An keyup() function and an if check done them all.
$("input[type='text']").on("keyup",function(){
if($(this).val()!="")
{
$(this).parent().addClass("active");
}else{
$(this).parent().removeClass("active");
}
})
.active{
background-color:red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
<input type="text" >
</div>
Thank you all for the answers, this is what worked for me after trying all the solutions. Hope it helps someone else.
function checkInputs() {
$('.input').each(function(){
if($(this).val() === ""){
$(this).parent().parent('.unit-card').removeClass('filled');
} else {
$(this).parent().parent('.unit-card').addClass('filled');
}
});
}

Displaying content when a checkbox is ticked [duplicate]

I have this code:
<fieldset class="question">
<label for="coupon_question">Do you have a coupon?</label>
<input class="coupon_question" type="checkbox" name="coupon_question" value="1" />
<span class="item-text">Yes</span>
</fieldset>
<fieldset class="answer">
<label for="coupon_field">Your coupon:</label>
<input type="text" name="coupon_field" id="coupon_field"/>
</fieldset>
And I would like to show/hide the "answer" fieldset (default is hidden) after a click on the checkbox in fieldset "question" How to do that. I wasn't able to do that using the technique for a classic elemetn like:
<script>
$().ready(function(){
$('.question').live('click',function() {
$('.answer').show(300);
}
,
function(){
$('.answer').hide(200);
}
);
});
</script>
Could somebody help me how to do that using checkbox? Also if possible to null (uncheck) the checkbox when it's hidden.
Try this
$(".answer").hide();
$(".coupon_question").click(function() {
if($(this).is(":checked")) {
$(".answer").show(300);
} else {
$(".answer").hide(200);
}
});
FIDDLE
Attach onchange event to the checkbox:
<input class="coupon_question" type="checkbox" name="coupon_question" value="1" onchange="valueChanged()"/>
<script type="text/javascript">
function valueChanged()
{
if($('.coupon_question').is(":checked"))
$(".answer").show();
else
$(".answer").hide();
}
</script>
Simplest - and I changed the checkbox class to ID as well:
$(function() {
$("#coupon_question").on("click",function() {
$(".answer").toggle(this.checked);
});
});
.answer { display:none }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<fieldset class="question">
<label for="coupon_question">Do you have a coupon?</label>
<input id="coupon_question" type="checkbox" name="coupon_question" value="1" />
<span class="item-text">Yes</span>
</fieldset>
<fieldset class="answer">
<label for="coupon_field">Your coupon:</label>
<input type="text" name="coupon_field" id="coupon_field" />
</fieldset>
Try
$(document).ready(function(){
//Register click events to all checkboxes inside question element
$(document).on('click', '.question input:checkbox', function() {
//Find the next answer element to the question and based on the checked status call either show or hide method
$(this).closest('.question').next('.answer')[this.checked? 'show' : 'hide']()
});
});
Demo: Fiddle
Or
$(document).ready(function(){
//Register click events to all checkboxes inside question element
$(document).on('click', '.question input:checkbox', function() {
//Find the next answer element to the question and based on the checked status call either show or hide method
var answer = $(this).closest('.question').next('.answer');
if(this.checked){
answer.show(300);
} else {
answer.hide(300);
}
});
});
Try this
<script>
$().ready(function(){
$('.coupon_question').live('click',function()
{
if ($('.coupon_question').is(':checked')) {
$(".answer").show();
} else {
$(".answer").hide();
}
});
});
</script>
$(document).ready(function() {
$(document).on("click", ".question", function(e) {
var checked = $(this).find("input:checkbox").is(":checked");
if (checked) {
$('.answer').show(300);
} else {
$('.answer').hide(300);
}
});
});

Remove input text when click button

I'm trying to remove input's val when clicking a button that appear when focusing on input.
This is my html:
<div class="search-area">
<form action="#" id="ingredientSearchForm">
<input type="text" placeholder="Arama" id="ingredientsSearch"/>
<span class="clearable"></span>
<span></span>
<input id="ingredientSearchSubmit" type="submit" class="hidden" placeholder="Arama"/>
</form>
</div>
And this is javascript function:
var searchinput = $(".search-area").find("input");
searchinput.focus(function(){
$(this).data('placeholder',$(this).attr('placeholder'));
$(this).attr('placeholder','');
$(this).siblings(".clearable").show();
});
$(".search-area").find(".clearable").on("click", function() {
$(this).val('');
});
searchinput.blur(function(){
$(this).attr('placeholder',$(this).data('placeholder'));
$(this).siblings(".clearable").hide();
});
.clearable is a span with background. Normally it is display:none.
I think you're wanting to clear searchinput on clicking .clearable?
If so, you should instead use:
$(".search-area").find(".clearable").on("click", function() {
searchinput.val('');
});
if you want to remove value of span then:
$(".search-area").find(".clearable").on("click", function() {
$(this).text('');
});
if you are trying to remove textbox value then:
$(".search-area").on("click",".clearable", function() {
$(this).closest("#ingredientSearchForm").find('#ingredientsSearch').val('');
});
