I cant hide divs which has spesific class with Jquery

Question

I changed my code to below code but this code doesnt make anything, no changing, no displaying:

jQuery(function ($) {
if( $(".ea-standard form div").hasClass("disabled") ){
        alert($(".ea-standard form div").hasClass("disabled"));
    $('.disabled').hide();
    } } );
jQuery(function ($) {
$(".ea-standard form div.disabled").alert($(".ea-standard form div").hasClass("disabled"));
    } );
jQuery(function ($) {
$(".ea-standard form div.disabled").hide();
    } );

why?

I have a form and when you select an option on a selectable list, other selectable lists on the form get ".disabled" form.But the disabled class doesnt disable them.

to disabled other selectable lists, I want to hide all things which has ".disable" class.

to make this, I wrote this code:

jQuery(function ($) {
    $(".ea-standard form div").hasClass(("disabled") => {
        alert($(".ea-standard form div").hasClass("disabled"));
    $('.disabled').hide();
    });
});

I want to check all form div and if any div get ".disabled" class in anytime, hide it suddenly.

but my js code editor says:

Expected an identifier and instead saw "disabled" . for this line:

$(".ea-standard form div").hasClass(("disabled") => {
how to solve?
