I want to create a dropdown list, which should display value instead of text.
But, when I click the dropdown, the option should display the text instead of value.
I have added an example here, but it is not working as expected:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Test</title>
<script src=".2.1/jquery.min.js"></script>
</head>
<body>
<select>
<option name="One" value="1">One</option>
<option name="Two" value="2">Two</option>
<option name="Three" value="3">Three</option>
<option name="Four" value="4">Four</option>
</select>
<script>
$(document).ready(function() {
$('select').click(function() {
$('select :selected').text($('select :selected').val());
});
});
</script>
</body>

});

it should be
$(this).find('option:selected').val()– treyBake Commented Jul 26, 2017 at 11:20 - It should be mousedown, not click, but there's no way you'll have "1" and "one" at the same time with the standard widget. You need to write your own widget or hide part of the standard one (for example with a div) – Denys Séguret Commented Jul 26, 2017 at 11:22

It isn't possible to create something as per your picture using a native
<select>. You'd need a plugin that uses CSS/Script to emulate a dropdown effect. Maybe just put "1 (One)" as the text in the first place? Also<option>tags don't have a "name" attribute. That belongs on the<select>and is used as the name of the field when submitting the form to the server. developer.mozilla/en-US/docs/Web/HTML/Element/option – ADyson Commented Jul 26, 2017 at 11:23 - @ThisGuyHasTwoThumbs thank you for your correction. – Raffel Commented Jul 26, 2017 at 11:26
- @Raffel no worries :) – treyBake Commented Jul 26, 2017 at 11:27

Reset to default 3Try this
$(document).ready(function() {
$("select option[value="+$('select option:selected').val()+"]").css({"background-color":"#0000ff","color":"#fff"});
$('select').change(function() {
$('select option')[0].value=$('select option:selected').val();
$('select option')[0].innerHTML=$('select option:selected').val();
$("select").val($('select option:selected').val());
$("select option").css({"background-color":"","color":""});
$("select option[value="+$('select option:selected').val()+"]").css({"background-color":"#0000ff","color":"#fff"});
});
});<script src="https://ajax.googleapis./ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select>
<option name="One" value="1" style="display:none">1</option>
<option name="One" value="1">One</option>
<option name="Two" value="2">Two</option>
<option name="Three" value="3">Three</option>
<option name="Four" value="4">Four</option>
</select>I have created an extra option which will be display none. Now whenever user will change any option I will change the value and text of the 1st element which is not displaying and Then setting the first value to be selected
If you are using bootstrap, I suggest using dropdown-menu and add a click listener on each dropdown item to change the dropdown-menu text.
this is a sample code I use for filtering table and show icon of filter type instead of value text.
<div class="btn-group flex-fill" dir="ltr">
<input type="text" enterkeyhint="search" class="form-control form-control-sm" id="filter_title" autoplete="off" onclick="$(this).val('')">
<button class="btn border dropdown-toggle p-1" data-toggle="dropdown">
<span id="ifilter_title"></span>
</button>
<div class="dropdown-menu text-center">
<a class="dropdown-item" onclick="$('#ifilter_title').text('1');"><span>One</span></a>
<a class="dropdown-item" onclick="$('#ifilter_title').text('2');"><span>Two</span></a>
<a class="dropdown-item" onclick="$('#ifilter_title').text('3');"><span>Three</span></a>
<a class="dropdown-item" onclick="$('#ifilter_title').text('4');"><span>Four</span></a>
</div>
It's impossible to do for a native select element, try adding label property in your option, <option value="1" label="1" selected>One</option>
