更好的方式动态链接到外部js文件？ [英] better way to dynamically link to an external js file?
问题描述
现在我正在使用
document.write（"< script language =''javascript''src =''jsFile" + i +
" .js''>< / script>"）;
它有效 - 我在每个文件中都有很多数据，只想要
访客必须下载必要的文件。是否有更好的方法
这样做？
好奇，因为页面没有在HTML验证器中验证。
Right now I''m using
document.write("<script language=''javascript'' src=''jsFile" + i +
".js''></script>");
It works -- I have a lot of data in each file and only want the
visitor to have to download the necessary file. Is there a better way
to do this?
Just curious because the page doesn''t validate in HTML validators.

是的，我有同样的问题，我决定使用
document.createElement，以便你如何做到这一点。
var newScript = document.createElement（" script"）;
newScript.setAttribute（" language"，" javascript"）;
newScript.setAttribute（" src" ，jsFile+ + i +。js;
现在，根据您使用的浏览器，某些选项是
avaliable here。
对于mozilla你可以做
document.body.appendChild（newScript）;
否则你可以这样做
document.documentElement.appendChild（newScript）;
但我决定做的是
document.getElementById（" scriptBase"）。 appendChild（newScript）;
如果你有很多o这些脚本就像你说你可以制作一个数组，
for循环和测试人员看看它是否是正确的客户端
Yes I had the same problem and I decided to use the
document.createElement so as for an example of how you would do this.
var newScript = document.createElement("script");
newScript.setAttribute("language","javascript");
newScript.setAttribute("src","jsFile" + i + ".js");
Now depending on what browser you are useing some options are
avaliable here.
For mozilla you can do
document.body.appendChild(newScript);
otherwise you can do this
document.documentElement.appendChild(newScript);
but what I decided to do is
document.getElementById("scriptBase").appendChild( newScript);
If you have alot of these scripts like you say you can make an array,
for loop and a tester to see if its the right client

尼克，
如果javascript有''<''或''&''，
，那么xhtml将无效其他一些细节 - 请查看David发布的链接
（这会引导您： http://www.htmlhelp.com/tools/validator/problems.html) 。
另请查看xhtml规范。
这是另一个想法 - 一个非常跨浏览器和
也将允许你的xhtml文件验证:-)
*在你的xhtml文件中...
< script type =''text / javascript''>
var jsFileNumber = 1;
< / script>
< script type =''text / javascript''src =''loader.js''>< / script>
*在loader.js中......
document.write（"<" +" script type =''text / javascript''src =''jsFile" + jsFileNumber +" .js''><" +" / script>"）;
Hi Nick,
The xhtml will be invalid if the javascript has ''<'' or ''&'',
and there are a few other details - check out the link David posted
(which will lead you to: http://www.htmlhelp.com/tools/validator/problems.html).
Also check out the xhtml spec.
Here''s another idea - one which is very cross-browser and
will also allow your xhtml file to validate :-)
* In your xhtml file...
<script type=''text/javascript''>
var jsFileNumber = 1;
</script>
<script type=''text/javascript'' src=''loader.js''></script>
* In loader.js...
document.write("<" + "script type=''text/javascript'' src=''jsFile" + jsFileNumber + ".js''><" + "/script>");
