[英]in node.js, how does one file in a module see functions in another file in the module?
in a module containing two files in ./modx
: modx.js
and helper.js
: 在一个模块中,该模块在./modx
包含两个文件: modx.js
和helper.js
:
./modx/package.json: ./modx/package.json:
{ "name" : "module x",
"main" : "./modx.js" }
./modx/helper.js: ./modx/helper.js:
function subFunc() { }
./modx/modx.js: ./modx/modx.js:
exports.mainFunc = function() {
var x = subFunc();
}
how do I make subFunc()
in helper.js
visible to modx.js
when both are in the modx
module? 我怎么做subFunc()
在helper.js
可见modx.js
当两者都是在modx
模块?
Inside ./modx/helper.js 在./modx/helper.js内部
var subFunc = function subFunc() {}
exports.subFunc = subFunc;
Inside .modx/modx.js 内部.modx / modx.js
var helper = require('./helper.js');
exports.mainFunc() {
var x = helper.subFunc();
}
The result here is that the subFunc function in helper.js is externally available and the mainFunc in modx.js is externally available. 结果是,helper.js中的subFunc函数在外部可用,而modx.js中的mainFunc在外部可用。
The only object in script A
visible from script B
is module.exports
. 从脚本B
可见的脚本A
唯一的对象是module.exports
。 Adding objects/functions to module.exports
(just like you did it with mainFunc
) makes them visible from the outside. 将对象/功能添加到module.exports
(就像使用mainFunc
)使它们从外部可见。 There is no other way. 没有别的办法了。
