javascript - Dynamic script not loading on history.go() -

i have static html page cannot edit- refer js file though, redirect url request on iis server js file- dynamically inject jquery can use it. here's code use insert jquery:

var script = document.createelement( 'script' ); script.src = 'http://code.jquery.com/jquery-1.9.1.js'; script.type = 'text/javascript'; script.onload = jqueryready;              //most browsers script.onreadystatechange = function () { //ie     if ( this.readystate == 'complete' ) {         jqueryready();     } }; 

this works great except in 1 specific case- if call history.go() on page when browser ie , page being served internal web server. hitting f5 not reload page properly. have put cursor in address bar , hit enter load right.

edit: forgot mention obvious- have breakpoint in jqueryready() function- , never gets hit- problem lies...

it works fine ie in dev environment if serve page , fire history.go() (with button click). works chrome, haven't tested firefox.

so there alternative history.go() fire 'true' page reload hitting enter in address bar?

this huge page - 6000 lines of html (i didn't write it) , jquery , javascript being loaded in head- know supposed load js stuff @ end of page. maybe related? feels timing issue...

anyone have thoughts things check/try? or know what's going on?

okay found it... solution here

bottom line code using isn't correct, recommended approach dynamically insert script document , handle ready event:

var script = document.createelement( "script" ); script.src = "/reporter/scripts/jquery-1.9.1.min.js"; if ( script.addeventlistener ) {     script.addeventlistener( "load", jqueryready, false ); } else if ( script.readystate ) {     script.onreadystatechange = jqueryready; } document.getelementsbytagname( 'head' )[0].appendchild( script ); 

additionally, needed check if jquery loaded in jqueryready function:

function jqueryready() {     // check if jquery exists     if ( typeof jquery != 'undefined' ) {         // stuff $(document).ready()     } } 

this seemed work in cases find.

hope helps else!
