I want to make input element name="sellprice" enable
- that is not an input, it's a dropdown
If i select value sell option else input element will be disabled. - from your current explanation i understand that you want to disable the drop-down if the third option is selected
If the third option is selected, the drop-down will be disabled.
$(document).ready(function() {
$('#mounth').change(function() {
if( $(this).val() == "sell") {
$('#mounth').prop( "disabled", true );
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.1/jquery.min.js"></script>
<select id="mounth" name="selling">
<option value="">-- Choose --</option>
<option value="free">Open Source</option>
<option value="sell">I Don't Want To Sell</option>
</select>
<div class="kd-title-show md-radio-inline">
<label>Price :</label>
<input id="textInput" type="textbox" class="form-title" name="sellprice" placeholder="Min-$5 to Max-$100 " disabled>
</div>
If you want to disable the input if the third option is selected, the following code will do it
$(document).ready(function() {
$('#mounth').change(function() {
if( $(this).val() == "sell") {
$('#textInput').prop( "disabled", true );
} else {
$('#textInput').prop( "disabled", false );
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.1/jquery.min.js"></script>
<select id="mounth" name="selling">
<option value="" selected="selected">-- Choose --</option>
<option value="free">Open Source</option>
<option value="sell">I Don't want To Sell</option>
</select>
<div class="kd-title-show md-radio-inline">
<label>Price :</label>
<input id="textInput" type="textbox" class="form-title" name="sellprice" placeholder="Min-$5 to Max-$100 ">
</div>


<select id="mounth" onchange="myOnChangeFunction()" name="selling">
<option value="">-- Choose --</option>
<option value="free">Open Source</option>
<option value="sell">I Wan't To Sell</option>
</select>
<div class="kd-title-show md-radio-inline">
<label for="4">Price :</label>
<input id="4" type="textbox" class="form-title" name="sellprice" placeholder="Min-$5 to Max-$100 " disabled>
</div>
in js
<script>
function myOnChangeFunction() {
var val = document.getElementById("mounth").value;
if(val === "sell"){
document.getElementById('4').disabled = false;
}else{
document.getElementById('4').disabled = true;
}
}
</script>

jQuery for showing different text field showing when select two different items in selectbox

How to display the text fields when choosing different option from the selectoption (if select USA option USA text field need to show)?
<select name="cntry">
<option value="us">USA</option>
<option value="uk">uk</option>
</select >
<input type="text" value="USA" name="USA">
<input type="text" value="UK" name="UK">

$('#country').on('change', function() {
$('input').each(function() {
$(this).css('display', 'none');
});
if (this.value === 'us') {
$('input[name="USA"]').css('display', 'initial')
}
if (this.value === 'uk') {
$('input[name="UK"]').css('display', 'initial')
}
});
input {
display: none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select id="country" name="cntry">
<option selected disabled hidden>Select your Country</option>

Display Checks on Checkboxes if other input is made

I am trying to show a checked checkbox if a value is selected on a select input. So if someone is choosing any value in the dropdown I want the checkbox to switch from off to on. Here is the html example.
I tried different things to achieve that but it is not working at all. My latest try looks like this:
$(document).ready(function() {
$('#subject').each(function() {
if (this.selected)
$("#box-4").prop("checked", true);
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select type="number" id="subject" name="subject">
<option value="none" selected disabled hidden>none</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
<input type="checkbox" id="box" disabled="disabled">
I think that I am on the right track here but don´t understand why this isn´t working at all.

$(document).ready(function() {
$('#subject').click(function() {
var option = document.getElementById('subject');
console.log(option.value);
if (option.value ==1 ||option.value==2)
$("#box").prop("checked", true);
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select type="number" id="subject" name="subject">
<option value="none" selected disabled hidden>none</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
<input type="checkbox" id="box" >

It should be .change()
Don't check whether it is selected or not
$(document).ready(function() {
// Change event
$('#subject').change(function() {
// On change, at first reseting all checkboxes state
$('input[type="checkbox"]').each(function() {
$(this).prop('checked', false);
});
// After reseting checkboxes state, check the appropriate checkbox
$("#box-" + this.value).prop("checked", true);
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select type="number" id="subject" name="subject">
<option value="none" selected disabled hidden>none</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
<input type="checkbox" id="box-1" disabled>
<input type="checkbox" id="box-2" disabled>

how to check a value from select, if you choose to give a value then it is not necessary?

this is my html,
I have two select if one select contains a value, then the required attribute is deleted,and the third select must be required
<select class="form-control costume-{{$stud}}" name="subject-{{$stud}}[]" id="sub1" disabled="disabled">
<option value="" selected> --------Select-------- </option>
<option value="math,indonesia">Math (Indonesia)</option>
<option value="math,english">Math (English)</option>
</select>
<select class="form-control costume-{{$stud}}" name="subject-{{$stud}}[]" id="sub2" disabled="disabled">
<option value="" selected> --------Select-------- </option>
<option value="science,indonesia">Science (Indonesia)</option>
<option value="science,english">Science (English)</option>
</select>
<select class="form-control select-long costume-{{$stud}}" name="location_id[{{$stud}}]" disabled="disabled">
<option value="" selected> -----Select------</option>
#foreach ($venue as $row)
<option value="{{$row['location_id']}}">{{$row['location_name']}}</option>
#endforeach
</select>
<input type="checkbox" id="enableSelect-{{$stud}}" onclick="getCheck({{$stud}});">
and this is my jquery
function getCheck(id){
var e = document.getElementById("sub1");
var sub1 = e.options[e.selectedIndex].value;
console.log(sub1);
if($('#enableSelect-' +id).is(':checked')) {
$('.costume-' +id).prop("disabled", false);
$('.costume-' +id).prop("required", true);
$('.visibility').show();
}else{
$('.costume-' +id).prop("disabled", true);
$('.costume-' +id).prop("required", false);
$('.visibility').hide();
}
}

Your JS doesn't correspond to the HTML, the selectors don't match up.
I would check form values and set the required like this :-
$('select').on('change', function() {
if($(this).val() != ""){
$('select').prop('required',false);
}
});
This would work with your HTML as by default the select value is ""
You would also need required="true" on the and your default option should be something like this -
<option value="" disabled selected>Select your option</option>
on the select elements by default.

how i enable disabled select n°2 after select n°1 was selected?

I did this in javascript code, but it does not work perfectly, the second "select" perfectly "disabled" by default, but I want when I selected an option from the first "select": the second will be "enabled" but it does not work,
and this is the code :
// JavaScript Document
var update_select = function () {
if ($("#edit-field-villes-tid").is(":selected")) {
$('#edit-field-villages-tid-option-limit').prop('disabled', false);
}else {
$('#edit-field-villages-tid-option-limit').prop('disabled', 'disabled');
}
};
$(update_select);
$("#edit-field-villes-tid").change(update_select);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<form >
<div class="views-exposed-widgets clearfix">
<label for="edit-field-villes-tid">Villes </label>
<select id="edit-field-villes-tid" name="field_villes_tid" class="form-select">
<option value="All" selected="selected">- Any -</option>
<option value="21">Sousse</option>
<option value="22">Tunis</option></select>
<label for="edit-field-villages-tid-option-limit">Villages </label>
<select id="edit-field-villages-tid-option-limit" name="field_villages_tid_option_limit" class="form-select">
<option value="All" selected="selected">- Any -</option>
<option value="24">El Zahra</option>
<option value="23">Sahlool</option>
</select>
<input class="ctools-use-ajax ctools-auto-submit-click js-hide form-submit" type="submit" id="edit-submit-tunisia" name="" value="Apply">
</div></form>
someone can help me ?

This worked for me;
<script language='javascript' type='text/javascript'>
var update_select = function () {
if ($("#edit-field-villes-tid")[0].selectedIndex > 0) {
console.log("is selected");
$('#edit-field-villages-tid-option-limit').prop('disabled', false);
} else {
console.log("is NOT selected");
$('#edit-field-villages-tid-option-limit').prop('disabled', true);
};
};
$(update_select);
$("#edit-field-villes-tid").on("change", update_select);
</script>
Changing the IF check to [0].selectedIndex > 0 was the key.

Drop down text input option

I want a drop down element where user can select from available options or select enter value option which in turn allows to enter value.
I specifically want that user can enter value only when they select "Enter a value " option.
Here is what I have tried so far.
HTML-
<div class="ginput_container">
<select name="input_4" id="input_1_4" class="medium gfield_select" tabindex="15">
<option value="0">None</option>
<option value="155">1-70</option>
<option value="185">71-250</option>
<option value="*">Enter value</option>
</select>
<input type="text" value="None" class="holder" >
</div>
JavaScript-
jQuery(".gfield_select").change(function() {
var val = jQuery(this).val();
var enter = jQuery(this).parent().find('option:selected').text();
var x = jQuery(this).parent();
if (enter ==="Enter a value" || enter === "Enter value"){
var holder = x.find('.holder');
holder.val('');
holder.prop('disabled',false);
holder.focus();
} else {
x.find('.holder').val(x.find('option:selected').text());
}
});
JS fiddle
however it wont work properly if i click the enter value option again.

I think there are many plugins that do what you want but if you want to create your own, it's a basic and simple solution.
You can create a select and a textbox with display:none like this:
<select id="ddlDropDownList">
<option value="1">Item 1</option>
<option value="2">Item 2</option>
<option value="3">Item 3</option>
<option value="-1">Enter Value</option>
</select>
<input id="txtTextBox" type="text" />
<style>
#txtTextBox{
display:none;
}
</style>
then try this JQuery:
$("#ddlDropDownList").change(function(){
if($(this).val() == '-1'){
$("#txtTextBox").fadeIn();
}else{
$("#txtTextBox").fadeOut();
}
});
Check JSFiddle Demo

I have forked your JSFiddle to http://jsfiddle.net/pwdst/4ymtmf7b/1/ which I hope does what you wanted to achieve.
HTML-
<div class="ginput_container">
<label for="input_1_4">Select option</label>
<select class="medium gfield_select" id="input_1_4" name="input_4" tabindex="15">
<option value="0">None</option>
<option value="155">1-70</option>
<option value="185">71-250</option>
<option value="*">Enter value</option>
</select>
<div>
<label class="hidden-label" for="input_1_4_other">Other value</label>
<input class="holder" id="input_1_4_other" disabled="disabled" name="input_1_4_other" placeholder="None" type="text" />
</div>
</div>
JavaScript-
jQuery(".gfield_select").change(function() {
var $this = jQuery(this);
var val = $this.val();
var holder = $this.parent().find('.holder');
if (val === "*"){
holder.val('');
holder.removeAttr('disabled');
holder.focus();
} else {
holder.val(this.options[this.selectedIndex].text);
holder.attr('disabled', 'disabled');
}
});
When the "Enter value" option is chosen then the input box is enabled, value set to an empty string, and it is focused. If another option is chosen then the text input is disabled again, and the text value from the select list is used.

Thanks guys
I guess i have found my answer
HTML-
<div class="ginput_container">
<select name="input_4" id="input_1_4" class="medium gfield_select" tabindex="15">

if (enter ==="Enter a value" || enter === "Enter value"){
var holder = x.find('.holder');
holder.val('');
holder.prop('disabled',false);
holder.focus();
jQuery(this).val("0"); // Change select value to None.
} else {
x.find('.holder').val(x.find('option:selected').text());
