javascript - The method of mounting to window cannot be executed?

Question

{Code...} This is an encapsulated script. But how to call bbb outside? aaa is mounted on the window, but aaa.bbb() cannot be executed.

You understand the timely function wrong:

            1、(function(){})();即时函数，会执行一遍；
                注：window.aaa = (function($) {
                    })(Zepto);
                   你这里的 window.aaa是没有用的 是undefined;
                   你里面的bbb函数也是一样，
                   
                  你外面当然访问不到呀！

Although I don’t quite understand how you want to call it, it seems that your aaa is mounted in the window, but aaa.bbb() cannot execute this sentence. Then you can change it to:

window.aaa = (function($) {

    var bbb = (function() {
        alert(1);
    });
    return {bbb:bbb};
})(Zepto);

You can use aaa.bbb() outside; if you write it like this, you have to pay attention to the closure and variable scope issues in the bbb method~!

Use module.export to expose it and require it outside.
