jQuery select change event get selected option
JqueryEventsJquery Problem Overview
I bound an event on the change event of my select elements with this:
$('select').on('change', '', function (e) {
});
How can I access the element which got selected when the change event occurs?
Jquery Solutions
Solution 1 - Jquery
$('select').on('change', function (e) {
var optionSelected = $("option:selected", this);
var valueSelected = this.value;
....
});
Solution 2 - Jquery
You can use the jQuery find method
$('select').change(function () {
var optionSelected = $(this).find("option:selected");
var valueSelected = optionSelected.val();
var textSelected = optionSelected.text();
});
The above solution works perfectly but I choose to add the following code for them willing to get the clicked option. It allows you get the selected option even when this select value has not changed. (Tested with Mozilla only)
$('select').find('option').click(function () {
var optionSelected = $(this);
var valueSelected = optionSelected.val();
var textSelected = optionSelected.text();
});
Solution 3 - Jquery
Delegated Alternative
In case anyone is using the delegated approach for their listener, use e.target
(it will refer to the select element).
$('#myform').on('change', 'select', function (e) {
var val = $(e.target).val();
var text = $(e.target).find("option:selected").text(); //only time the find is required
var name = $(e.target).attr('name');
}
Solution 4 - Jquery
<select id="selectId">
<option value="A">A</option>
<option value="B">B</option>
<option value="C">C</option>
</select>
$('#selectId').on('change', function () {
var selectVal = $("#selectId option:selected").val();
});
First create a select option
. After that using jquery
you can get current selected value when user change select option
value.
Solution 5 - Jquery
I find this shorter and cleaner. Besides, you can iterate through selected items if there are more than one;
$('select').on('change', function () {
var selectedValue = this.selectedOptions[0].value;
var selectedText = this.selectedOptions[0].text;
});
Solution 6 - Jquery
$('#_SelectID').change(function () {
var SelectedText = $('option:selected',this).text();
var SelectedValue = $('option:selected',this).val();
});
Solution 7 - Jquery
Another and short way to get value of selected value,
$('#selectElement').on('change',function(){
var selectedVal = $(this).val();
^^^^ ^^^^ -> presents #selectElement selected value
|
v
presents #selectElement,
});
Solution 8 - Jquery
This can also work fine
(function(jQuery) {
$(document).ready(function() {
$("#select_menu").change(function() {
var selectedOption = $("#select_menu").val()
});
});
})(jQuery);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.3/jquery.min.js"></script>
Solution 9 - Jquery
See official API documentation https://api.jquery.com/selected-selector/
This good works:
$( "select" ).on('change',function() {
var str = "";
// For multiple choice
$( "select option:selected" ).each(function() {
str += $( this ).val() + " ";
});
});
and
$( "select" ).on('change',function() {
// For unique choice
var selVal = $( "select option:selected" ).val();
});
and be easy for unique choice
var SelVal = $( "#idSelect option:selected" ).val();
Solution 10 - Jquery
You can use this jquery select change event for get selected option value
$(document).ready(function () {
$('body').on('change','#select', function() {
$('#show_selected').val(this.value);
});
});
