I ended by this code after helping with many thanks of others here in this website. Now, in the following code of submitting the form, I want the value of the hidden input field to be instead of Other when shown the result.
<form action="" method="post">
<div class="row">
<div class="col-sm-8 col-sm-offs et-2">
<select class="form-control" name="country" id="country" required >
<option value="">Please select your country</option>
<option value="A">Country A</option>
<option value="B">Country B</option>
<option value="C">Country C</option>
<option value="Other">Other</option>
</select>
<input type ="text" id="country_other" style="display:none">
<button type="submit" class="btn btn-gpsingh">Next</a>
</div>
</div>
</form>
<script>
$("#country").change(function(){
var value = this.value;
if(value =='Other')
{
$("#country_other").show();
$("#country_other").attr('required', false);
}
else
{
$("#country_other").hide();
$("#country_other").val('');
$("#country_other").attr('required', false);
}
});
</script>
Something you could try, if I understood correctly, would be to remove the name attribute from the SELECT menu if the chosen value is other and assign the name attribute instead to the text input element - when the form is submitted the item in the POST array with the name of country would come from the text field and not the select menu...
$('#country').change(function(){
if( this.value == 'Other' ){
$('#country_other').show();
$('#country_other').attr('required', false);
/* remove name from select & add to text field */
$('#country_other').attr('name', $(this).attr('name') );
$(this).removeAttr('name');
} else {
$('#country_other').hide();
$('#country_other').val('');
$('#country_other').attr('required', false);
/* remove name attribute from text field and assign back to select menu */
$(this).attr('name', $('#country_other').attr('name') );
$('#country_other').removeAttr('name');
}
});

I have created with javascript and I get a result of a string.I get that result on my html code
<div id="results"></div>
Next,I want when I select for example Red to check if it is the the same thing (string), the select option - > Red with the string of this code
<div id="results"></div>
I was trying to do it but I failed.It is not working not even sure ,if I press the submit button I will send the string.
<div id="results"></div>
<form method="post" >
<select >
<option value="">--Please choose an option--</option>
<option value="R">Red</option>
<option value="B">Black</option>
</select>
<input id="results" type="submit" value="results"/>
It appears that you want to check whether the selected option is equal to the text value of the div #results. You can achieve this effect like so:
$(document).ready(function(){
var select = $("select");
$("input[type=\"button\"]").click(function(){
var text = select.find(":selected").text();
if(text==$("#results").text()){
$("#results").html(text+" is equal!");
}else{
$("#results").html(text+" is not equal :(");
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="results">Red</div>
<form method="post" >
<select >
<option value="">--Please choose an option--</option>
<option value="R">Red</option>
<option value="B">Black</option>
</select>
<input id="results" type="button" value="results"/>
</form>
A form is going to be Sending data somewhere, it would be best to remove the form, leaving the select and button elements. In the button add the code onclick='myFunction() ; when the button is clicked it will run the javascript function called myFunction(). Also you need to give the select a Id. I'm using selectInput
<script>myFunction() { document.getElementById('result').innerHTML = document.getElementById('selectInput').value;} </script>
Now when ever the button is pressed it will set the content of the div equal to the value entity in the selected select box option
You lack an action attribute.
<form method="post" action="path/to/file">
<select name="select">
<option value="">--Please choose an option--</option>
<option value="R">Red</option>
<option value="B">Black</option>
</select>
<input type="submit" value="Get Results" />
</form>
Use a function, and a regular button. No form is needed.
<button onclick='func()'></button>
const func = () => {...}
It's my first contact with js so please don't hate me
I have something like this:
function Zmiana(isChecked) {
document.getElementById('test').type = 'text';
}
<div class="dropdown">
<select id="test" name="producent" class="dropdown-select">
<option value="Apple">Apple</option>
<option value="Samsung">Samsung</option>
<option value="Lenovo">Lenovo</option>
</select> <br>
</div>
But it doesn't work
You won't be changing the select into a textbox. Instead, you'll have both a select and a textbox. The checkbox will simply determine which is shown.
Also, your select should include a first choice that is not considered valid so that you don't get a submitted value that the user didn't choose.
.hidden { display:none; }
<input type="checkbox" id="check">Check to enter text directly
<div class="dropdown">
<select id="test" name="producent" class="dropdown-select">
<option value="">--- Choose ---</option>
<option value="Apple">Apple</option>
<option value="Samsung">Samsung</option>
<option value="Lenovo">Lenovo</option>
</select>
<input id="data" class="hidden">
</div>
<script>
let text = document.getElementById('data');
let check = document.getElementById("check");
let select = document.getElementById("test");
// You must set up your function to handle the
// click event of the checkbox
check.addEventListener("click", Zmiana);
function Zmiana(){
// Add or remvoe the hidden class based on
// whether it's already in use
select.classList.toggle("hidden");
text.classList.toggle("hidden");
}
</script>
I have a select form element with various options. One of the options is "other". So when "other" is selected a hidden field is displayed for the user to enter the value not on the list. All that works fine. The problem is when a user selects any of the other options and submits the form, the value is not passed. Whereas, if the "other" option is selected and fills the text box then submits the form, the value of the text box is passed.
this is the select and the hidden text field:
<select name="memo" required class="newtxtbox" id="memo" onchange='checkvalue()'>
<option disabled="disabled" selected="selected">Select</option>
<option value="Donation for Bulletin">Bulletin</option>
<option value="Donation for Care Ministry">Care Ministry</option>
<option value="Donation for Cathedral Choir">Cathedral Choir</option>
<option value="Donation for Other">Other - (please specify below) </option>
</select>
<input type="text" style="display:none" name="memo" id="other">
and this is JavaScript:
function checkvalue()
{
if(document.getElementById('memo').value == 'Donation for Other') {
document.getElementById('other').style.display='block';
}
else {
document.getElementById('other').style.display='none';
}
}
I am sure i am missing something small but can't figure out what it is.
Here is a visual example of a small workaround. What I did was simply changing the name attribute of each element. I have added a CSS rule that displays the element with name="memo" as blue. The element that is blue will be sent to the server.
I have also expanded the javascript code so that you can test it out here on SO. You don't have to include the code after // added for testing purpose in your code. Click on "run code snippet" and try the submit button.
function checkvalue() {
var select = document.getElementById('memo');
var input = document.getElementById('other');
if (select.value == 'Donation for Other') {
document.getElementById('other').style.display = 'block';
select.name = '';
input.name = 'memo'; // form `memo` will now contain this input
} else {
document.getElementById('other').style.display = 'none';
select.name = 'memo';
input.name = '';
}
}
// added for testing purpose
document.getElementById('test').addEventListener('submit', function(e) {
e.preventDefault(); // no no submit
// FormData is HTML5 js object that contains ... data from the form ...
var fd = new FormData(this);
// .entries() isn't widely supported yet.
for (var tuple of fd.entries()) {
console.log(tuple[0] + ' contains value "' + tuple[1] + '"');
}
});
/*
added this for visibility of changes
element that is blue is being sent
*/
input[name="memo"],
select[name="memo"] {
background-color: lightblue;
}
<form id="test">
<select name="memo" required class="newtxtbox" id="memo" onchange='checkvalue()'>
<option disabled="disabled" selected="selected">Select</option>
<option value="Donation for Bulletin">Bulletin</option>
<option value="Donation for Care Ministry">Care Ministry</option>
<option value="Donation for Cathedral Choir">Cathedral Choir</option>
<option value="Donation for Other">Other - (please specify below) </option>
</select>
<input type="text" style="display:none" id="other">
<input type="submit" value="submit" />
</form>
I have 4 select tag with class name select2 assigned to it. I want to make the border turn to red if there's no selected options or has an value equal to empty or 0. I've tried to add class using jquery but it makes all select.select2 border turns red.
Style
<style>
.errorType {
border-color: #F00 !important;
}
</style>
HTML
<select name="category" class="form-control select2" id="category" onChange="search_Operator(this.value)">
<option value="0"> Select Operator Category</option>
<option value="1">one</option> <option value="2"> two</option>
</select>
<select name="operatorName" class="form-control select2" id="operatorName" onChange="">
<option value="0"> Select operator Name</option>
<option value="1">one</option>
<option value="2"> two</option>
</select>
<select name="regionName" class="form-control select2" id="regionName">
<option value="0"> Select region Name</option>
<option value="1">one</option>
<option value="2"> two</option>
</select>
<select name="type" class="form-control select2" id="type">
<option value="0"> Select type </option>
</select>
JQUERY
$(function () {
$(".select2").select2();
});
$(".select2-selection").addClass('errorType');
Any idea?
Thanks in advance.
I've attached a function to the click event of the submit button, in order to check the value of every select element on the page:
$(function () {
$('.form-control-select2').select2();
$('#submit_btn').on('click', function(){
var submit_form = true;
$(".form-control-select2").each(function(){
var selected_value = $(this).val();
if (selected_value==0 || selected_value=='') {
$(this).next().find('.select2-selection').addClass('errorType');
submit_form = false;
} else {
$(this).next().find('.select2-selection').removeClass('errorType');
}
});
return submit_form;
});
});
Fiddle here: https://jsfiddle.net/64a41thz/21/.
Also, if you want to remove the red border when valid selection is made, add the following code:
$('.form-control-select2').on('change', function(){
if ($(this).val()!=0 && $(this).val()!='') {
$(this).next().find('.select2-selection').removeClass('errorType');
}
});
Fiddle here: https://jsfiddle.net/64a41thz/24/.
This does the trick. You just need to replace #yourButton with the actual ID you use.
$(document).on("click", "#yourButton", function() {
$(".select2").each(function(index, element) {
$(element).removeClass("errorType");
if ($(element).val() === "0") {
$(element).addClass("errorType");
}
});
});
Put your select tag inside a form with an id="submit" as shown
<form class="" action="" method="post" id="submit">
and add a button below the 4 select tags with this attribute
onclick="return submit_form('form#submit')"
the button should be like this,
<button type="button" class="btn btn-default" onclick="return submit_form('form#submit')">Submit</button>
In your jquery
function submit_form (form_id) {
$(form_id).find('select[name]').each(function (index, node) {
if (node.value == 0) {
var id = "select#" + node.id;
$(id).addClass('errorType');
}
});
}
This will search select tag with name as attribute, if found, it will get the value of the name and check of its empty or not. If found empty it will add new class that turns that select tag into a red border.
Hope this will help
I have a text input, alongside I have option tag with two options.
Basically I want to save the text that the user enters while switching between options, but if the user choose an option that he already enterd a text the text should appear in the input field as the default value.
And of course it's part of the submit form.
Many thanks in advance!
<div>
<p>please enter your description for each of the languages</p>
<input id="description" type="text">

You can use local storage for this if you want to persist what is saved, otherwise a variable would be good enough.
Example with variable
var previous;
var state = {};
$("#language").on('focus', function() {
previous = $(this).val()
}).change(function() {
state[previous] = $("#test").val();
$("#test").val('');
if (typeof(state[$(this).val()]) != 'undefined') {
$("#test").val(state[$(this).val()]);
}
$("#test").focus();
});

<form>
<input name="test" id="test" />
