javascript-如何“流利的API"； (也称为“链接")? [英] javascript - how to "fluent API" (also calling "chaining")?

问题描述

我试图理解的是如何在方法调用之后创建调用方法.

I am trying to understand is how to create call methods after a method call.

例如在jquery中，您有类似以下内容:

For example in jquery you have something like this:

$("blah").data("data-id");

我怎么做:

blah("cow").foo("moo");

笨蛋和foo在哪儿console.log(value)?

推荐答案

您所指的是流利的API"(也称为链接").您的函数需要返回具有您要在其上调用的下一个方法的对象.例如，

What you're referring to is a "fluent API" (also calling "chaining"). Your functions need to return the object that has the next method you want to call on it. For example,

var obj = function(){
        var self = this;
        self.blah = function(v){ console.log(v); return self; };
        self.foo = function(v){ console.log(v); return self; };
    };

    var o = new obj();
    o.blah("cow").foo("moo");
