问题描述
现在,我创建了一个包含许多函数的.js文件,然后将其链接到我的html页面。这是有效的,但我想知道在我的页面中插入js以及避免与范围冲突的最佳方法(良好做法)...
谢谢。
Nowdays, i create a .js file with a lot of functions and then I link it to my html pages. That's working but I want to know what's the best way (good practices) to insert js in my pages and avoid conflicts with scope...Thank you.
推荐答案
你可以将它们包装在一个匿名函数中,如:
You could wrap them in an anonymous function like:
(function(){ /* */ })();
但是,如果你需要重新使用所有的javascript函数''在其他地方写过(在其他脚本中),你最好创建一个可以访问它们的单个全局对象。要么:
However, if you need to re-use all of the javascript functions you've written elsewhere (in other scripts), you're better off creating a single global object on which they can be accessed. Either like:
var mySingleGlobalObject={};
mySingleGlobalObject.someVariable='a string value';
mySingleGlobalObject.someMethod=function(par1, par2){ /* */ };
或替代的,更短的语法(做同样的事情):
or the alternative, shorter syntax (which does the same thing):
var mySingleGlobalObject={
someVariable:'a string value',
someMethod:function(par1, par2){ /* */ }
};
稍后可以从其他脚本访问此项,例如:
This can then be accessed later from other scripts like:
mySingleGlobalObject.someMethod('jack', 'jill');
