摆脱document.write？

Question

我有一个函数：

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

，这就是所谓一次：

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

我需要摆脱的文件撰写的，因为它不是在XHTML在Firefox的支持。我该怎么做呢？ jQuery是罚款:)

全码：

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

你为什么不把它在文档中？

<script src="http://maps.gstatic.com/intl/sv_se/mapfiles/api-3/3/1b/main.js"> 
</script> 

如果它需要你做休息后加载脚本，把两个脚本标记在身体的一端（谷歌地图脚本作为第二个）

Answer 2

有这个已经存在的jQuery核心$.getScript()：

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

它的行为以类似的方式，创造了<script>元素和追加它到<head> ...但不是document.write()。

Answer 3

你可以说：

var tag = $('<script src="' + src + '" type="text/javascript"></script>'); 
$("head").append(tag); 

Answer 4

document.documentElement.appendChild(document.createElement("script")).src = "http://maps.gstatic.com/intl/sv_se/mapfiles/api-3/3/1b/main.js";
