How to show input and remove it based on select box? - javascript

I have two input I need to show one of them based on the select box:
html code:
<select id="type-price">
<option value="">Choose one...</option>
<option value="numeric">Numeric </option>
<option value="percentage">Percentage</option>
</select>
<div id="input_type1">
<input type="text" name="Numeric">
</div>
<div id="input_type2">
<input type="text" name="Percentage">
</div>
jQuery code:
$('#type-price').on('change',function(){
if($(this).val()=== "numeric"){
$("#input_type1").show();
$("#input_type2").hide();
}else if ($(this).val()=== "percentage"){
$("#input_type1").hide();
$("#input_type2").show();
}
});
Now it's totally fine like that but my issue I have php request when I show input_type1 then hide input_type2 the request pick up second one which is null so I need to delete the hide one at all form Dom tree!

You can empty the div which contain the input and you will have only one input in your DOM. On each change of select, it will fill the concerne div by the input html.
Also you'd used wrong selector, the # selector is for id and you have used an class in your HTML code.
The JQuery class selector is ..
function removeAll() {
$("#input_type1").html('');
$("#input_type2").html('');
}
removeAll();
$('#type-price').on('change',function(){
removeAll();
if ($(this).val() === "numeric"){
$("#input_type1").append('<input type="text" value="numeric">');
} else if ($(this).val() === "percentage"){
$("#input_type2").append('<input type="text" value="percentage">');
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select id="type-price">
<option value="" disabled selected>Choose one...</option>
<option value="numeric">Numeric </option>
<option value="percentage">Percentage</option>
</select>
<div id="input_type1">
<input type="text" value="numeric">
</div>
<div id="input_type2">
<input type="text" value="percentage">
</div>

Here is an example with one field.
$(function() {
$("#type-price").change(function(e) {
$(".input-type").fadeIn("slow").find("input").attr("name", $(this).val().toLowerCase());
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select id="type-price">
<option value="">Choose one...</option>
<option value="numeric">Numeric </option>
<option value="percentage">Percentage</option>
</select>
<div class="input-type" style="display: none;">
<input type="text">
</div>

Besides some syntax problem in your jQuery class selector, Thinking about performance, It's simply better to prevent the (non-visible) input from being sent.
Shorter coding and less dom manipulation.
$('#type-price').on('change',function(){
$('.input_type1').toggle($(this).val()=="numeric");
$('.input_type2').toggle($(this).val()=="percentage");
});
//To prevent the non-visible from being posted
//Eithr we check the form using submit handler or the button and prevent the
//from being sent do our stuff then send it...
$('#myForm').submit(function() {
$('input:hidden').attr('name', '');
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form id="myForm">
<select id="type-price">
<option value="">Choose one...</option>
<option value="numeric">Numeric </option>
<option value="percentage">Percentage</option>
</select>
<div class="input_type1">
<input name="inp1" type="text" placeholder="1">
</div>
<div class="input_type2">
<input name="inp2" type="text" placeholder="2">
</div>
<input type="submit" value="Send">
</form>

Remove error text when input is unlocked in jquery

I have a form with a select, input and a function that locks my input when an option is selected.
I added a warning that inputs are locked when someone selects an option. I would like to add a function to remove this warning when someone chooses an option with value="".
It's removing my warning but for example when I choose option text 1 then text 2 my warning displays twice and then when I choose a selection with first option it removes warning but only first.
How to change it so that the warning displays only once, and not more times, and removes it after select with option first.
$(function() {
$('#stato').change(function() {
var value = $(this).val(); //Pobranie wartości z tego selecta
if (value == "") {
$('#data_consegna').prop('disabled', false);
$("#error").remove();
} else {
$('#data_consegna').prop('disabled', true);
$('#data_consegna').after('<div id="error" style="color:red;">Input locked</div>');
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script>
<div class="col-4">
<label>Enabled </label>
<select name="stato" id="stato" class="form-control">
<option value="">Choose</option>
<option value="Text1">Text1</option>
<option value="Text2">Text2</option>
<option value="Text3">Text3</option>
<option value="Text4">Text4</option>
</select>
</div>
<div class="col-4">
<label>Disabled when choose option in select</label>
<input id="data_consegna" type="text" class="form-control" name="data_consegna" placeholder="Data Consegna" />
</div>
my warning displays twice
You don't check if it's already there or remove it.
removes only first
IDs must be unique, so $("#error").remove(); will only remove the first one. Use classes instead of IDs to remove multiple elements. If you only add once, this would not be an issue; just explaining why it removes only the first.
As noted in the other answer, the best solution is to simply .show()/.hide(), so I won't repeat that here.
To update your code, you can always remove the error, then add it back if needed - this isn't the most efficient as noted above.
Updated snippet:
$(function() {
$('#stato').change(function() {
var value = $(this).val(); //Pobranie wartości z tego selecta
// always remove any existing error
$("#error").remove();
if (value == "") {
$('#data_consegna').prop('disabled', false);
} else {
$('#data_consegna').prop('disabled', true);
$('#data_consegna').after('<div id="error" style="color:red;">Input locked</div>');
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script>
<div class="col-4">
<label>Enabled </label>
<select name="stato" id="stato" class="form-control">
<option value="">Choose</option>
<option value="Text1">Text1</option>
<option value="Text2">Text2</option>
<option value="Text3">Text3</option>
<option value="Text4">Text4</option>
</select>
</div>
<div class="col-4">
<label>Disabled when choose option in select</label>
<input id="data_consegna" type="text" class="form-control" name="data_consegna" placeholder="Data Consegna" />
</div>
Also note, as it's using an ID, it can only be used for a single error message.
The simple way to achieve what you require is to have the notification div always contained in the DOM, but hidden, and then hide/show it depending on the state of the select, like this:
jQuery(function($) {
$('#stato').change(function() {
var value = $(this).val();
if (value == "") {
$('#data_consegna').prop('disabled', false);
$("#error").hide();
} else {
$('#data_consegna').prop('disabled', true);
$('#error').show();
}
});
});
#error {
color: red;
display: none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script>
<div class="col-4">
<label>Enabled </label>
<select name="stato" id="stato" class="form-control">
<option value="">Choose</option>
<option value="Text1">Text1</option>
<option value="Text2">Text2</option>
<option value="Text3">Text3</option>
<option value="Text4">Text4</option>
</select>
</div>
<div class="col-4">
<label>Disabled when choose option in select</label>
<input id="data_consegna" type="text" class="form-control" name="data_consegna" placeholder="Data Consegna" />
<div id="error">Input locked</div>
</div>

How to get the selected text of options in multiple select?

I am trying to get the selected option in multiple select, I can get the value in the form of an array, but I can't get the text of the option.
$(function() {
$('#sizeAddCategory').change(function(e) {
var selected = $(e.target).text();
console.log("selected " + selected);
$('#textAreaAddCategory').val(selected.join(','));
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="form-group col-sm-6">
<label for="sel1">Select Sizes (hold ctrl or shift (or drag with the mouse) to select more than one):</label>
<br/>
<select required class="form-control" id="sizeAddCategory" multiple>
<option value="1">one</option>
<option value="2">two</option>
<option value="3">three</option>
<option value="4">four</option>
</select>
</div>
<div class="form-group col-md-3">
<label for="name">Selected Sizes</label>
<br/>
<textarea required disabled rows="4" class="form-control" id="textAreaAddCategory"></textarea>
</div>
On $(e.target).text(), I am getting all the options text, I need the text of only selected options, so I can display it in the textarea.
Using .text() on a select will give the text of the control - i.e. all of the options, not just the selected ones.
To get the selected text (not value as you pointed out you can already get), you can use:
$(this).find("option:checked").map((i,e)=>$(e).text()).toArray();
Here, $(this).find("option:checked") will give you the option elements that have been selected while the .map will return the .text() for each of those values into a jquery array, with .toArray() to convert to a normal js array.
$(function() {
$('#sizeAddCategory').change(function() {
var selected = $(this).find("option:checked").map((i,e)=>$(e).text()).toArray();
console.log("selected", selected);
$('#textAreaAddCategory').val(selected.join(','));
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="form-group col-sm-6">
<label for="sel1">Select Sizes (hold ctrl or shift (or drag with the mouse) to select more than one):</label>
<br/>
<select required class="form-control" id="sizeAddCategory" multiple>
<option value="1">one</option>
<option value="2">two</option>
<option value="3">three</option>
<option value="4">four</option>
</select>
</div>
<div class="form-group col-md-3">
<label for="name">Selected Sizes</label>
<br/>
<textarea required disabled rows="4" class="form-control" id="textAreaAddCategory"></textarea>
</div>
It's because the target that you're defining is in the select tag. Instead of using:
$('#sizeAddCategory').change(function(e) {
use:
$('.option-category').click(function(e) {
and add a class in the options:
<option value="{{$size->id}}" class="option-category">{{$size->name}}</option>
you write :
var selected = $(e.target).text();
you should get the value of selectbox and
you should write
var selected = $(e.target).val();
oh my god
i right now understand what did you mean
ok
write :
$("#selectBox").change(function(e){
var x = $(e.target).find("option:checked").text();
console.log(x);
});

Change Button Name="" and Form Action based on Select Option in Jquery

Hi I have form which contains three search criteria.
These search criteria are jobs, resume, recruitment consultant.
Based on the drop down, fields are updated accordingly.
Based on the select value I want to change the action on the form, and name of the submit button. Problem is putting values with hyphen in option select makes jquery not work.
<form method="get" name="search" action="search-job-results?">
<select class="homepage4" name="search_for" id="search_for">
<option value="Jobs">Jobs</option>
<option value="Resume">Resumes</option>
<option value="Recruitment Consultant">Recruitment Consultants</option>
</select>
<input type="submit" name="searchjobbutton" id="search_submit" value="Submit">
</form>
Change the form action as per following
action="search-recruitment-consultant-results?"
action="search-resume-results?"
action="search-job-results?"
And the button name (NOT VALUE OR TEXT) as per following
name="searchrecruitmentconsultantbutton"
name="searchresumebutton"
name="searchjobbutton"
I put these in option values accordingly
search-recruitment-consultant-results?
search-resume-results?
search-job-results?
and then used
<select name="search_for" onchange="this.form.action=this.value;">
but putting hyphen in option values makes the jquery show/hide not work
Try this code, see i have use hyphen in option and it works properly.
<form method="get" name="search" id="form" action="search-job-results?">
<select class="homepage4" name="search_for" id="search_for">
<option value="Jobs">Jobs</option>
<option value="Resume">Resumes</option>
<option value="Recruitment-Consultant">Recruitment Consultants</option>
</form>
<script>
$(document).ready(function() {
$("#search_for").change(function(){
if($(this).val()=='Jobs')
{
$("#form").attr("action",'search-job-results?');
$("#search_submit").attr('name',"searchjobbutton");
}
else if($(this).val()=='Resume'){
$("#form").attr("action",'search-resume-results?');
$("#search_submit").attr('name',"searchresumebutton");
}
else if($(this).val()=='Recruitment-Consultant'){
$("#form").attr("action",'search-recruitment-consultant-results?');
$("#search_submit").attr('name',"searchrecruitmentconsultantbutton");
}
});
});
</script>
i think this will help you
add id for your form 'formId'
$(document).ready(function(){
$('#search_for').change(function(){
var cur = $(this);
var search = cur.val();
if(search == 'job'){
$('#formId').attr('action', 'search-job-results?');
$("search_submit").attr('name', 'searchjobbutton');
} else if(search == 'Resume'){
$('#formId').attr('action', 'search-resume-results?');
$("search_submit").attr('name', 'searchresumebutton');
}else if(search == 'Recruitment Consultant'){
$('#formId').attr('action', 'search-recruitment-consultant-results?');
$("search_submit").attr('name', 'searchrecruitmentconsultantbutton');
}
});
});
try this
Add data attribute with button name
only you need to add - onchange="$(this).parent().attr('action', $(this).val()); $('#search_submit').val($(this).find(':selected').data('name'));" in the select
and data-name="" in the option
<form method="get" name="search" action="search-job-results?">
<select class="homepage4" name="search_for" id="search_for" onchange="$(this).parent().attr('action', $(this).val()); $('#search_submit').val($(this).find(':selected').data('name'));">
<option value="search-job-results?" data-name="searchjobbutton">Jobs</option>
<option value="search-resume-results?" data-name="searchresumebutton">Resumes</option>
<option value="search-recruitment-consultant-results?" data-name="searchrecruitmentconsultantbutton">Recruitment Consultants</option>
</select>
<input type="submit" name="searchjobbutton" id="search_submit" value="Submit">
<script
src="https://code.jquery.com/jquery-3.2.1.slim.min.js"
integrity="sha256-k2WSCIexGzOj3Euiig+TlR8gA0EmPjuc79OEeY5L45g="

<form method="get" name="search" action="search-job-results?">
<select class="homepage4" name="search_for" id="search_for" onchange="$(this).parent().attr('action', $(this).val()); $('#search_submit').val($(this).find(':selected').data('name'));">
<option value="search-job-results?" data-name="searchjobbutton">Jobs</option>
<option value="search-resume-results?" data-name="searchresumebutton">Resumes</option>
<option value="search-recruitment-consultant-results?" data-name="searchrecruitmentconsultantbutton">Recruitment Consultants</option>
</select>
<input type="submit" name="searchjobbutton" id="search_submit" value="Submit">
</form>
Instead of writing multiple forms, just write one and use .change() and data-* attribute which is used to create custom tags. Store the button names inside <option data-name="button name"> then you can access this value with on change.
The data-* attributes is used to store custom data private to the page or application.
.change()
Bind an event handler to the "change" JavaScript event, or trigger that event on an element.
$('#search_for').on('change', function () {
$('form[name="search"]').attr('action', $(this).val()).find(':submit').attr('name', $(this).find(':selected').data('name'));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form method="get" name="search" action="search-job-results?">
<select class="homepage4" name="search_for" id="search_for">
<option data-name="searchjobbutton" value="search-job-results?">Jobs</option>
<option data-name="searchresumebutton" value="search-resume-results?">Resumes</option>
<option data-name="searchrecruitmentconsultantbutton" value="search-recruitment-consultant-results?">Recruitment Consultants</option>
</select>
<input type="submit" name="searchjobbutton" id="search_submit" value="Submit">
</form>

Change the CSS attribute if an option selected with jQuery

I have this code:
<select>
<option disabled selected>Select Method</option>
<option value="question">Question</option>
<option value="password">Password</option>
<option value="email">Email</option>
<option value="none">None</option>
</select>
Now I want when user select each of them some div that hidden in css with display:none; get visible for example when user select Question the div that have question id get visible or when Password selected the div that have password id get visible.
I try this but not work:
$(document).ready(function(){
if ($("#auth option:selected").text() == "question"){
$("#question").css("display","block");
}
});
So how can I do this?
If you follow the pattern you have done so far, you have to write code for each option. If your options and div elements are coupled with value and id, you can simply do like this,
$("select").change(function() {
$("div").hide();
$("#" + $(this).val()).show();
});
Demo Fiddle
Here is Demo for this , remove disabled from select tag so that user can select the options
Jsfiddle
http://jsfiddle.net/adarshkr/z9gcf40r/2/
Code
HTML
<select id="showdiv">
<option disabled selected>Select Method</option>
<option value="question">Question</option>
<option value="password">Password</option>
<option value="email">Email</option>
<option value="none">None</option>
</select>
<div id="question" class="hide">
<p>question</p>
</div>
<div id="password" class="hide">
<p>password</p>
</div>
<div id="email" class="hide">
<p>email</p>
</div>
<div id="none" class="hide">
<p>none</p>
</div>
CSS
.hide{
display:none
}
JAVASCRIPT
$("select").change(function(){
$("div").hide();
$("#"+$(this).val()).show();
});
try this,
$('#auth').on('change', function() {
var that = $(this).val();
if (that === "question"){
$("#question").css("display","block");
}
});
Better check value than the text.
$(document).ready(function(){
if ($("#auth option:selected").val() == "question"){
$("#question").css("display","block");
}
});

Hiding a class of Div depending on Select statement option

I'm fairly new to javascript and I'm trying to make an form for my website and I'm stuck on the javascript,
This is what I have:
<script type="text/javascript">
function hide(opt) {
if (getElementsByClassName(opt).style.display='none';){
getElementsByClassName(opt).style.display='block';
}
else{
getElementsByClassName(opt).style.display='none';
}
}
</script>
What I intended the script to do was recieve a variable (the option chosen by the user) and then reveal all the elements with the class of the same name (so if the option was orc the orc div would be displayed, but be hidden if the option chosen was elf etc.)
Html:
<form name="chargen" action="" method="post">
Name:<Input name="name" type="text" />
Gender:<select name="gender">
<option>Choose Gender...</option>
<option>Male</option>
<option>Female</option>
</select>
Species:<select name="species" onchange="hide(document.chargen.species.options[
document.chargen.species.selectedIndex ].value)">
<option> Choose Species...</option>
<option value="human">Human</option>
<option value="orc">Orc</option>
<option value="elf">Elf</option>
<option value="dwarf">Dwarf</option>
<option value="drow">Drow</option>
<option value="ent">Ent</option>
</select>
<div class="human" style="display:none;">
Sub Species:<select name="subspecies1">
<option>Norseman</option>
<option>Hellenic</option>
<option>Heartlander</option>
</select>
</div>
<div class="orc" style="display:none;">
Sub Species:<select name="subspecies2">
<option>Black Orc</option>
<option>Fel Orc</option>
<option>Green Orc</option>
</select>
</div>
<div class="human" style="display:none;">
Homeland:<select name="homeland1">
<option>Choose Homeland...</option>
<option value="citadel">Citadel</option>
<option value="wildharn">Wildharn</option>
<option value="Merith">Merith</option>
</select>
</div>
<div class="orc" style="display:none;">
Homeland:<select name="homeland2">
<option>Choose Homeland...</option>
<option value="1">Berherak</option>
<option value="2">Vasberan</option>
</select>
</div>
Unfortunately nothing happens when I change the contents of the species combobox (I've tried on multiple browsers) What am I doing wrong?
I realise that getElementsByClassName() is a HTML5 function, but according to the interwebs it is compatible with all major browsers.
Thanks for your time
getElementsByClassName returns an array, you must iterate on the result. And be careful to the = in tests (instead of ==).
But I suggest you have a look at jquery. Your life will be easier as what you want can be done as :
$('.human, .orc, .elf, .dwarf, .drow, .ent').hide();
$('.'+opt).show();
(see fiddle : http://jsfiddle.net/dystroy/2GmZ3/)
