jQuery select change event get selected option

Question

$('select').on('change', function (e) {
    var optionSelected = $("option:selected", this);
    var valueSelected = this.value;
    ....
});

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();
   });

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');
}

JSFiddle Demo

<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.

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;
});

$('#_SelectID').change(function () {
        var SelectedText = $('option:selected',this).text();
        var SelectedValue = $('option:selected',this).val();
});

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, 
});
