javascript - jQuery - Bind Unbind click event depending of condition -

-

i need disable click event jquery mobile button depending if array empty or not. when location loads don't want user able click, once array has values, change that.

this have tried:

if (points.length != 0){ $('#addplaces').bind('click');} else{$('#addplaces').unbind('click');}

i have tried same condition with:

$('#addplaces').on('click'); $('#addplaces').off('click');

what doing wrong? thanks!

why wanna that. return event when array empty , continue execution otherwise.

$('#addplaces').on('click', function() {      if (points.length === 0) {         return     } });

this way need not keep toggling event.
