How to check if a jQuery-ui widget is rendered or not (version 1.11.2)? To avoid Uncaught Error: cannot call methods on xxxx prior to initialization; attempted to call method 'xxxx'
Uncaught Error: cannot call methods on xxxx prior to initialization; attempted to call method 'xxxx'
errors.
One way is to use the data api like
If your widget name is datepicker and the element id is date
then
if($('#date').data('datepicker')){
//call method since it is initialized
}
Demo: Fiddle
The same can be done via the :data() selector
if ($('#date').is(':data(datepicker)')) {
//call method since it is initialized
}
