For example [1,2,3].extend ([4,5,6]) =[1,2,3,4,5,6]If there is a list of list, I want to reduce them into a list, how to do? People who know a bit of functional programming will think of reduce, but direct reduce (lambda x,y:x.extend (y), lists) is not possible because the original implementation in the Python list clas

Construct ($ options) {$This-> Options =$ Options ;}FunctionRun (){Return1;}}; For the above syntax, you can ignore PHP that you don't understand.CodeAfter writing it, you can create a new class and return an object. The above methods and attributes can be used in the object $ obj. $ OBJ =NewAncestor (1 ); What about inheritance?

Deep Analysis of jQuery. extend source codeDuring website development, some jQuery plug-ins are often written for easy use. Naturally, a key method is indispensable-> jQuery. extend (), which is used to expand jQuery objects. Let's talk about the implementation principle of this function today. This method not only implements plug-ins, but also has its own functions and extends objects. Like this: var perso

jquery has two methods for developing plug-ins, namely:JQuery.fn.extend ();Jquery.extend ();Jquery.fnJquery.fn = Jquery.prototype = {Init:function (selector, context) {//....//...};The original Jquery.fn = Jquery.prototype. It's certainly not strange to prototype.Although JavaScript does not have a clear class concept, it is more convenient to use a class to understand it. jquery is a well-encapsulated class, such as we use the statement $ ("#btn1 ″) to generate an instance of the jquery class.J

The basic use of jquery extendThrough 285 lines of source jquery.extend = JQuery.fn.extend = function() { , the Extend method is either a static method that hangs directly into JQuery, Either the attached to FN is actually the instance method on the prototype (referring to the assignment operation of 283 rows). The Extend method can pass an object, similar to a plug-in, or can be copied by multi

In Python, there are two ways to add elements to a list: Extend and append. But there are some differences in the use of the two:1.append You can add a single element, or you can add an iterative object, but extend can only add an iterative object:arr = [1,2,3,4]in [155]:arr.append (5) in [156]:arrout[156]:[1, 2, 3, 4, 5]in [157]:arr_1= [1,2,3,4]in [158]:arr_1.extend
