在Javascript中,如何继承和扩展正在继承的方法?(In Javascript, how can you inherit and extend a method that is being inherited?)
我已经四处寻找,但遗憾的是没有找到这个问题的副本。
文件1:
var Graph = Backbone.View.extend({ move: function() { //some stuff }, //more stuff })文件2:
define ([ './graph.js' ]), function( graph ) { var SubGraph = Backbone.View.extend({ // this file needs to inherit what is within the move method but extend it to include other stuff })如何在不破坏现有属性的情况下扩展继承的属性?
I've searched around, but haven't found a duplicate of this question, unfortunately.
File1:
var Graph = Backbone.View.extend({ move: function() { //some stuff }, //more stuff })File 2:
define ([ './graph.js' ]), function( graph ) { var SubGraph = Backbone.View.extend({ // this file needs to inherit what is within the move method but extend it to include other stuff })How do you extend the inherited properties without destroying the existing ones?
最满意答案
看起来你正在使用Require.js
做:
图形模块:
define(function() { return Backbone.View.extend({ move: function() { //some stuff } });SubGraph模块:
define(['require', './graph'], function(require) { var Graph = require('./graph'); return Graph.extend({ // this file needs to inherit what.... } });或者,如果您没有定义很多依赖项,请不要包含require :
define(['./graph'], function(Graph) { return Graph.extend({ // this file needs to inherit what.... } });Looks like you're using Require.js
Do:
Graph module:
define(function() { return Backbone.View.extend({ move: function() { //some stuff } });SubGraph module:
define(['require', './graph'], function(require) { var Graph = require('./graph'); return Graph.extend({ // this file needs to inherit what.... } });Or if you don't define a lot of dependencies, don't include require:
define(['./graph'], function(Graph) { return Graph.extend({ // this file needs to inherit what.... } });更多推荐
