Selector - Attribute Selectors
Multiple attribute selectors can be used to refer to several Attributes of an element, or Even several times to the same attribute.
Here, the selector Matches all SPAN
Elements Whose "hello" attribute has Exactly the value "Cleveland" and Whose "Goodbye" attribute has Exactly the value "Columbus":
span[hello="Cleveland"][goodbye="Columbus"] { color: blue; }
Or in free translation:
The selection of multiple attributes in the selector can be used to reference multiple attributes of an element, or even multiple times the same attribute.
Here, the selector combines all elements SPAN
where the attribute "hello" has the exact value "Cleveland" and the attribute "Goodbye" has the exact value "Columbus";
span[hello="Cleveland"][goodbye="Columbus"] { color: blue; }
Try:
$('input[name="FLG_SEXOX_CLIEN"], input[value="{{ $cliente->FLG_SEXOX_CLIEN }}"]').attr('ckecked').trigger("chosen:updated");
