Is there any way to check if an element has jquery select2 already applied to it?

Question

I want to apply select2 to a bunch of jquery elements on the page that all have the same class name but it looks like if i call select2() on an element that already has had a select2() called on it then it blows up. here is my code

 $('.MyDropdowns').each(function (i, obj) {
    $(obj).select2({ width: "455px" });
});

so I want something like:

 $('.MyDripdowns').each(function (i, obj) {
    if (!$(obj).HasSelect2Initiatized)
    {
        $(obj).select2({ width: "455px" });
    }
});

Does anything like this exist?

Answer 1

you can check if the element has select2 attribute

$('.MyDripdowns').each(function (i, obj) {
    if (!$(obj).data('select2'))
    {
        $(obj).select2({ width: "455px" });
    }
});

EDIT

As @Fr0zenFyr said in his comment for v4.0 you can use :

if (!$(obj).hasClass("select2-hidden-accessible"))
