javascript - 摆脱 document.write？

Question

我有一个函数:

  function getScript(src) {
    document.write('<' + 'script src="' + src + '"' +
                   ' type="text/javascript"><' + '/script>');
  }

它被调用一次:

  getScript("http://maps.gstatic.com/intl/sv_se/mapfiles/api-3/3/1b/main.js");
})();

我需要删除 document.write，因为它在 firefox 中的 xhtml 中不受支持。我该怎么做呢？ Jquery 很好:)

完整代码:

window.google = window.google || {};
google.maps = google.maps || {};
(function() {

  function getScript(src) {
    document.write('<' + 'script src="' + src + '"' +
                   ' type="text/javascript"><' + '/script>');
  }

  var modules = google.maps.modules = {};
  google.maps.__gjsload__ = function(name, text) {
    modules[name] = text;
  };

  google.maps.Load = function(apiLoad) {
    delete google.maps.Load;
    apiLoad([null,[[["http://mt0.google.com/vt?lyrs=m@139\u0026src=api\u0026hl=sv-SE\u0026","http://mt1.google.com/vt?lyrs=m@139\u0026src=api\u0026hl=sv-SE\u0026"]],[["http://khm0.google.com/kh?v=74\u0026hl=sv-SE\u0026","http://khm1.google.com/kh?v=74\u0026hl=sv-SE\u0026"],null,null,null,1],[["http://mt0.google.com/vt?lyrs=h@139\u0026src=api\u0026hl=sv-SE\u0026","http://mt1.google.com/vt?lyrs=h@139\u0026src=api\u0026hl=sv-SE\u0026"],null,null,"imgtp=png32\u0026"],[["http://mt0.google.com/vt?lyrs=t@126,r@139\u0026src=api\u0026hl=sv-SE\u0026","http://mt1.google.com/vt?lyrs=t@126,r@139\u0026src=api\u0026hl=sv-SE\u0026"]],null,[[null,0,7,7,[[[330000000,1246050000],[386200000,1293600000]],[[366500000,1297000000],[386200000,1320034790]]],["http://mt0.gmaptiles.co.kr/mt?v=kr1.12\u0026hl=sv-SE\u0026","http://mt1.gmaptiles.co.kr/mt?v=kr1.12\u0026hl=sv-SE\u0026"]],[null,0,8,9,[[[330000000,1246050000],[386200000,1279600000]],[[345000000,1279600000],[386200000,1286700000]],[[348900000,1286700000],[386200000,1293600000]],[[354690000,1293600000],[386200000,1320034790]]],["http://mt0.gmaptiles.co.kr/mt?v=kr1.12\u0026hl=sv-SE\u0026","http://mt1.gmaptiles.co.kr/mt?v=kr1.12\u0026hl=sv-SE\u0026"]],[null,0,10,19,[[[329890840,1246055600],[386930130,1284960940]],[[344646740,1284960940],[386930130,1288476560]],[[350277470,1288476560],[386930130,1310531620]],[[370277730,1310531620],[386930130,1320034790]]],["http://mt0.gmaptiles.co.kr/mt?v=kr1.12\u0026hl=sv-SE\u0026","http://mt1.gmaptiles.co.kr/mt?v=kr1.12\u0026hl=sv-SE\u0026"]],[null,3,7,7,[[[330000000,1246050000],[386200000,1293600000]],[[366500000,1297000000],[386200000,1320034790]]],["http://mt0.gmaptiles.co.kr/mt?v=kr1p.12\u0026hl=sv-SE\u0026","http://mt1.gmaptiles.co.kr/mt?v=kr1p.12\u0026hl=sv-SE\u0026"]],[null,3,8,9,[[[330000000,1246050000],[386200000,1279600000]],[[345000000,1279600000],[386200000,1286700000]],[[348900000,1286700000],[386200000,1293600000]],[[354690000,1293600000],[386200000,1320034790]]],["http://mt0.gmaptiles.co.kr/mt?v=kr1p.12\u0026hl=sv-SE\u0026","http://mt1.gmaptiles.co.kr/mt?v=kr1p.12\u0026hl=sv-SE\u0026"]],[null,3,10,null,[[[329890840,1246055600],[386930130,1284960940]],[[344646740,1284960940],[386930130,1288476560]],[[350277470,1288476560],[386930130,1310531620]],[[370277730,1310531620],[386930130,1320034790]]],["http://mt0.gmaptiles.co.kr/mt?v=kr1p.12\u0026hl=sv-SE\u0026","http://mt1.gmaptiles.co.kr/mt?v=kr1p.12\u0026hl=sv-SE\u0026"]]],[["http://cbk0.google.com/cbk?","http://cbk1.google.com/cbk?"]],[["http://khmdb0.google.com/kh?v=33\u0026hl=sv-SE\u0026","http://khmdb1.google.com/kh?v=33\u0026hl=sv-SE\u0026"]],[["http://mt0.google.com/mapslt?hl=sv-SE\u0026","http://mt1.google.com/mapslt?hl=sv-SE\u0026"]],[["http://mt0.google.com/mapslt/ft?hl=sv-SE\u0026","http://mt1.google.com/mapslt/ft?hl=sv-SE\u0026"]]],["sv-SE","US",null,0,null,"http://maps.google.com","http://maps.gstatic.com/intl/sv_se/mapfiles/","http://gg.google.com","https://maps.googleapis.com","http://maps.googleapis.com"],["http://maps.gstatic.com/intl/sv_se/mapfiles/api-3/3/1b","3.3.1b"],[4241463462],1,null,null,null,null,0,""], loadScriptTime);

Answer 1

有一个 $.getScript() 因为这已经存在于 jQuery 核心中:

$.getScript("http://maps.gstatic.com/intl/sv_se/mapfiles/api-3/3/1b/main.js");

它的行为方式类似，创建一个 <script>元素并将其附加到 <head> ...但不是 document.write() .
