How to get attribute from selected option of select in jQuery?

Question

I have the next selectbox in HTML:

<select id="listbox-taskStatus" class="selectpicker">
    <option status="0">In progress</option>
    <option status="1">Not started</option>
    <option status="2">Done</option>
    <option status="3">Failed</option>
</select>

I want to read the attribute value from selected option.

If just to take the value, it's simple:

var value = $('#listbox-taskStatus').val();

But what should I do, if I want to get the attribute value from selected option? I know, that .attr() must help, but when I tried to use it I've got the incorrect result.

I've tried the next:

var status = $('#listbox-taskStatus option').attr('status');

But the returned value is always 0 despite on fact I was selecting different option.

What's wrong, how to solve my problem?

$('#listbox-taskStatus option') gets all of the option elements. You just want the selected one. – Repurchase

@undefined , because it's not value. Even jQuery have made special function .val() fro getting values from DOM elements, and the value of <option> is inside its tag. So as for me I can't name the attribute as value, but it's my own opinion. Of course it's a vexed question, but I think it's some freedom for naming the attributes. – Plica

Answer 1

Use :selected Selector

var status = $('#listbox-taskStatus option:selected').attr('status');

However, I would recommend you to use data- prefixed attribute. Then you can use .data()

var status = $('#listbox-taskStatus option:selected').data('status');

var optionAttr1 = $('#listbox-taskStatus').find('option:selected').attr("status");
var optionAttr = $('#listbox-taskStatus option:selected').attr("status");
