javascript - Should I include the Google Map script tag on every page of my website? -

-

it seems if not include script tag google map on each page of website, error: "uncaught referenceerror: google not defined".

if include script tag on page there no map error "uncaught typeerror: cannot read property 'offsetwidth' of null".

maybe need sort of check system in javascript see if id exists? wasn't sure correct way of incorporating google map api?

this javascript looks like:
// google map

    function initialize() {     var mapcanvas = document.getelementbyid('map-canvas');     var mapoptions = {       center: new google.maps.latlng(44.5403, -78.5463),       zoom: 8,       maptypeid: google.maps.maptypeid.roadmap     }     var map = new google.maps.map(mapcanvas, mapoptions)   }   google.maps.event.adddomlistener(window, 'load', initialize);

  • include on every page intend use map.

  • don't include elsewhere.

  • fix javascript not things not need done. if don't intend render map, don't write code renders map.

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
