, the second is the change in the form of the value of the data, so that the value of the data and the value of the form tied together.

Introduced People who have used JavaScript frameworks such as ANGULARJS, backbone, or ember are familiar with how MVC works in the UI (user interface, front-end). These frameworks implement MVC, which makes it easier to implement changes to views as needed in a single page, while the core concept of model-view-Controller (MVC) is the controller that handles incoming requests, a view that displays information, a model that represents business rules, a

To better use the relevant knowledge of Ajax learned in these two days, I made a simple online chat room. Ideas The realization chat room, basically is through the Ajax to pass the data, lets the PHP to realize to the data the difference enters and the search, then gives the front-end JavaScript to implement the page the renewal, achieves the instant chat function. Message display Area The message dis

The example in this article describes how JavaScript simple judgments check boxes are selected and the values are removed. Share to everyone for your reference. Specifically as follows: Here, using JavaScript to get the value of the checkbox, a friend usually encounters a particular element in the form when they start

This article describes the JavaScript simple implementation object-oriented programming inheritance instance code. Share to everyone for your reference, specific as follows: An object-oriented language must have four basic characteristics: 1. Encapsulation capability (that is, allowing a variable or function of a basic data type to be placed in a class to form

I have been very interested in front-end development recently, especially with the help of popular Ajax libraries such as jquery, it is indeed convenient to make good dynamic effects even if I do not have good JavaScript skills. But I don't think that's enough. After all, everything is encapsulated by others. You have to study native Javascript in depth to be steadfast. Today, I saw a good blog and introduc

};The function constructor constructor is in the following form:var Func2 = new Function ("Para1", "Para2",..., "Function body"); What needs to be explained here is that only the function declaration form can be promoted! For example:function declaration Functions MyTest1 () { func (); function func () { Console.log ("I can be promoted"); }} myTest1 ();//Functional expression Functions MyTest2 () { func (); var func = fu
