jQuery - getting custom attribute from selected option

Given the following:

<select id="location">
    <option value="a" myTag="123">My option</option>
    <option value="b" myTag="456">My other option</option>
</select>

<input type="hidden" id="setMyTag" />

<script>
    $(function() {
        $("#location").change(function(){
            var element = $(this);
            var myTag = element.attr("myTag");

            $('#setMyTag').val(myTag);
        });
    });
</script>

That does not work...
What do I need to do to get the value of the hidden field updated to the value of myTag when the select is changed. I'm assuming I need to do something about getting the currently selected value...?

If you want to call according to dynamic row ID use:

var data = $(`#var_name_${row_id} option:selected`).attr('value2');

var optionAttr1 = $(this).find('option:selected').attr("myTag");
var optionAttr = $('#location option:selected').attr("myTag");

Stright forward way is :

Get selected option attribute value:

var selectedOptionAttributeValue =   $('#location option:selected').attr('myTag');

Get Selected Text:

 var selectedOptionText = $('#location').text();

Get selected value:

var selectedOptionValue = $('#location').val();

You can also try this one as well with data-myTag

<select id="location">
    <option value="a" data-myTag="123">My option</option>
    <option value="b" data-myTag="456">My other option</option>
</select>

<input type="hidden" id="setMyTag" />

<script>
    $(function() {
        $("#location").change(function(){
           var myTag = $('option:selected', this).data("myTag");

           $('#setMyTag').val(myTag);
        });
    });
</script>

Try This Example:

$("#location").change(function(){

    var tag = $("option[value="+$(this).val()+"]", this).attr('mytag');

    $('#setMyTag').val(tag); 

});

Here is the entire script with an AJAX call to target a single list within a page with multiple lists. None of the other stuff above worked for me until I used the "id" attribute even though my attribute name is "ItemKey". By using the debugger

Chrome Debug

I was able to see that the selected option had attributes: with a map to the JQuery "id" and the value.

<html>
<head>
<script type="text/JavaScript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
</head>
<body>
<select id="List1"></select>
<select id="List2">
<option id="40000">List item #1</option>
<option id="27888">List item #2</option>
</select>

<div></div>
</body>
<script type="text/JavaScript">
//get a reference to the select element
$select = $('#List1');

//request the JSON data and parse into the select element
$.ajax({
url: 'list.json',
dataType:'JSON',
success:function(data){

//clear the current content of the select
$select.html('');

//iterate over the data and append a select option
$.each(data.List, function(key, val){
$select.append('<option id="' + val.ItemKey + '">' + val.ItemText + '</option>');
})
},

error:function(){

//if there is an error append a 'none available' option
$select.html('<option id="-1">none available</option>');
}
});

$( "#List1" ).change(function () {
var optionSelected = $('#List1 option:selected').attr('id');
$( "div" ).text( optionSelected );
});
</script>
</html>

Here is the JSON File to create...

{  
"List":[  
{  
"Sort":1,
"parentID":0,
"ItemKey":100,
"ItemText":"ListItem-#1"
},
{  
"Sort":2,
"parentID":0,
"ItemKey":200,
"ItemText":"ListItem-#2"
},
{  
"Sort":3,
"parentID":0,
"ItemKey":300,
"ItemText":"ListItem-#3"
},
{  
"Sort":4,
"parentID":0,
"ItemKey":400,
"ItemText":"ListItem-#4"
}
]
}

Hope this helps, thank you all above for getting me this far.

Simpler syntax if one form.

var option = $('option:selected').attr('mytag')

... if more than one form.

var option = $('select#myform option:selected').attr('mytag')

Suppose you have many selects. This can do it:

$('.selectClass').change(function(){
    var optionSelected = $(this).find('option:selected').attr('optionAtribute');
    alert(optionSelected);//this will show the value of the atribute of that option.
});

You're pretty close:

var myTag = $(':selected', element).attr("myTag");

Try this:

$("#location").change(function(){
            var element = $("option:selected", this);
            var myTag = element.attr("myTag");

            $('#setMyTag').val(myTag);
        });

In the callback function for change(), this refers to the select, not to the selected option.

That because the element is the "Select" and not "Option" in which you have the custom tag.

Try this: $("#location option:selected").attr("myTag").

Hope this helps.

You're adding the event handler to the <select> element.
Therefore, $(this) will be the dropdown itself, not the selected <option>.

You need to find the selected <option>, like this:

var option = $('option:selected', this).attr('mytag');
