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"))

Answer 2

Working solution:

$('.MyDripdowns:not([class^="select2"])').each(function (i, obj) {     $(obj).select2({width: "455px"}); })

1. ^= attribute starts with selector
2. :not selector
