javascript - How can I check for/use jQuery in closure loaded before jQuery? -

i have js file contains closure, file loaded before jquery, let's can't moved. how can pass in or check jquery view use in closure?

this i've got far:

(function myclosure() {      var interval = setinterval(function() {         if (typeof jquery !== 'undefined') {             dojquerystuff();             clearinterval(interval);         }     }, 500);      function dojquerystuff() {         // stuff jquery.     } })(); 

it works, there "better" way? think i'm doing wrong whenever use setinterval() things this, fact losing time in 500ms.

you wait , attach execution window.onload event, assuming jquery loaded once window loaded...

window.onload = function() {     // stuff jquery };
