為javascript增加import方法，用于引入需要的js文件。通過增加element的方法進行添加的方法是從網上得來的。我將原來作為參數傳進來的type改成了根據文件名后綴來判斷，看起來更加直觀一些。

/**//*--------------------------------------------------------------------------+

/a.js)

function JSLoad(url, container, type, defer, language, title)
12 {
13 // verify / attain container
14 if(container == undefined || container == null) container = this;
15
16 // setup container
17 if(typeof container.write == "undefined")
18 if(typeof container.document != "undefined")
19 container = container.document;
20 else throw "Invalid container. Unable to load [" + url + "]";
21
22 // no type set
23 if(type == undefined || type == null)
24
{
25 type = '';
26
27 // no language so set default type
28 if(language == undefined || language == null)
29 {
30 language = undefined;
31 type = "text/javascript";
32
}
33 }
34
35 // set default language
36 if(language == undefined || language == null) language = "JavaScript";
37
38 // set title
39 if(title == undefined || title == null) title = '';
40
41 // set defer
42 if(defer == undefined) defer = false;
43
44 // build the script object
45 var script = container.createElement("script");
46 script.defer = defer;
47 script.language = language;
48 script.title = title;
49 script.type = type;
50 script.src = url;
51
52 // dynamically load the script via it's container
53 var head = container.getElementsByTagName("head")[0];
54 head.appendChild(script);
55 }
使用方法：$import("test.js");
