如何获取JavaScript文件的对象（句柄）？

Question

I am using requireJS and I have two files (app,js and file1.js). I need to instantiate file1.js in app.js using require() and then call a function in file1.js from app.js. How do I do that?

app.js

define(function(require){
    var file1 = require('file1.js');
    file1.load_function();
}

file1.js

define([], function(){
    var load_function = function(){
        //Some logic
    }
}

But here, the "load_function()" is being loaded without being invoked. And there is error in the way I am using "var file1" as a handle.

Is there a way I can get a handle on "file1.js" from "app.js"?

How can prevent the function from loading(executing) without it being invoked?

There is no error in your app.js file. The line var file1 = require('file1.js'); loads the module file1.js and binds it to the local variable file1 . Then you can call file1.load_function() .

You need to export your function:

define(function (require, exports, module) {
    var load_function = function(){
        //Some logic
    }
    exports.load_function = load_function;
});

By the way you should never put the .js extension in your module names so refer to the module in the file named file1.js as file1 .
