javascript - Switch between .bind() and .on() - dynamically -

i want this, because working third-party scripts releated internet marketing. of them may contain jquery library included within , interfere recent or latest jquery library included on website.

hence, i'd switch between .on() , .bind() dynamically upon website load of variable.

for example, let's have global variable:

var incjs = false; 

and depending of third-party script, know if have older lib included i'd use this.

function tpnetwork () {     incjs = true;      startgateway('xxxxx');      $('#fancybox-outer')         .delay(1000)         .fadeto(300, 1);      preventgtw();     widgetstyle(); } 

now may see there's function @ bottom widgetstyle()

that function contain loads of things, important part following:

$(window).on('resize', function () {     if ($('.widget_wrap').length) widgetcenter_horizontal(); }); 

it has .on() method there. not supported in old jquery that's been used third-party network. i'd switch every single .on() .bind() don't know how to, without duplicating things. did this, it's duplicate , believe there's easier way.

if (!incjs) {     $(window).on('resize', function () {         if ($('.widget_wrap').length) widgetcenter_horizontal();     }); } else {     $(window).bind('resize', function () {         if ($('.widget_wrap').length) widgetcenter_horizontal();     }); } 

any kind of tips/help appreciated. out of ideas , doing researches found nothing.

what about:

$(function(){     if(!$.fn.on) $.fn.on = $.fn.bind; }); 

of course, excluding delegation support.
