Apply ()Apply (M,dimcode,f,fargs) M is a matrix. DimCode is the dimension number, 1 is applied to the row, and 2 is the function for the column. F is a function Fargs is an optional parameter set for F > z > f + x/c(2, 8)+ }> apply(z,1,f) #f函数得到两个元素，则为几行，竖着来的 [,1] [,2] [,3][1,] 0.5 1.000 1.50[2,] 0.5 0.625 0.75Lapply ()Lapply ()

Call (Thisobj,arg1,arg2 ...), apply (Thisobj,[obj1,obj2 ...]) These two methods are non-inherited methods that are included in each function Call (thisobj[, args]) and apply (thisobj[, args)) function is the same, in simple terms is to change the current use of this method in the object of this point, point to the calling method of the Thisobj object the difference between the two (the first argument is t

Apply: Methods can hijack another object's method, inheriting another object's properties. Function.apply (Obj,args) method can receive two parametersOBJ: This object will replace the This object in the function classArgs: This is an array, which is passed as a parameter to function (args-->arguments) Call: Same as apply, except that the argument list is not the same. Function.call (o

This is the SQL Server Help documentation for the description of apply:Use the APPLY operator (version 2005 or later) to invoke a table-valued function for each row returned by an external table expression that implements a query operation. The table-valued function acts as the right input and the outer table expression as the left input. The resulting row is combined as the final output by evaluating the right input for each row in the left input. Th

A simple understanding of call in Javascript and the ability to apply javascript to object orientation was later added. For compatibility, many strange things were made, Function Animal () {this. name = "Animal"; this. showName = function () {alert (this. name) ;}} function Cat () {this. name = "Cat";} var animal = new Animal (); var cat = new Cat (); // use the call or apply method to convert the showNa

Apply and call are important methods in JavaScript, and although programming is seldom accessible, the JS framework uses these 2 methods everywhere.These 2 methods are in Function.prototype, which means that each JS function has these 2 methods.Alert (Function.prototype.hasOwnProperty ("apply"));//truealert (Object.prototype.hasOwnProperty ("Apply");// FalseThe f

In JS, these three are used to change the function of the this object to the point, they have what kind of difference.Before we tell the difference, we should summarize the similarities of the three:1, are used to change the function of the this object point.2. The first parameter is the object to which this is directed.3. You can use the following parameters to pass the parameter.So where are their differences, first look at an example. var XW = { Name: "Xiao Wang", Gender: "Male", Ag

Introduction to call, apply, and bind methods in JavaScript The call, apply, and bind methods in JavaScript are not easy to understand. In fact, the ideas behind them are not very complicated. I hope this article will help you better understand these three very similar and mysterious methods.

AngularJS digest loop and $ apply Recently, I was writing AngularJS and encountered a problem. I used Ajax to asynchronously request background data and assigned the result to the attributes of an object in the current scope. How can I not retrieve them on the page, however, it can be printed normally on the js end. Cause analysis: The first reason is that the front-end page binding command is incorrect and cannot be properly displayed. However, the c
