Recently I wrote a simple calculator in javascript, and it feels okay to test it on my own. Let's take a look at the interface:
The interface is like this, but what is the function?
Now it's just a simple standard calculator that can perform addition, subtraction, multiplic

Recently, when my colleagues were working on a project, they needed an animation library to support the following requirements:
Can start, pause (linear, non-linear tween support), continue, end
Supports parallel processing of multiple styles
It is better to run without relying on a framework
The smaller the file size, the better.
He looked for some existing plug-ins or libraries that could hardly meet or be balanced. At this requirement, I wrote a relatively

Recently used JavaScript to write a simple calculator, their own testing feel good, first of all to watch the next interface:
This is the interface, but what about the function?
Now it's just a simple standard calculator that can perform subtraction continuous operations
This calculator is made up of two parts: a mxml file with a foreground interface, a background controller as file. The Mxml file is responsible for displaying the calculator interface, which handles the information sent by the user and calculates the results. In this tutorial we mainly study:
[List] The Application class
The Panel container
The Label element
The Grid container
The Button element[/list]

This example describes the code for JavaScript to write a simple calculator. Share to everyone for your reference. Specifically as follows:The screenshot of the running effect is as follows:
The specific code is as follows
JS
function. function Class () {if (! Initializing this. init) {this. init. apply (this, arguments) ;}// set the prototype Class for the subclass. prototype = prototype; // set the constructor Class for the subclass. prototype. constructor = Class; // sets the extend method of the subclass so that the subclass can be inherited by the extend method. extend = arguments. callee; return Class ;}})();
By using the simple-inheritance library, we can impleme
The suffix expression evaluates to
Calcsuffix:function () {
this.result = [];
for (var i = 0; i
In fact, in the implementation of the time will find that infix, suffix is just a difficult point, more complex place is the whole calculator state changes (or data changes)
In this simple calculator, there are numbers (0-9), oper
The pure javascript code implements the calculator function. Next, let's share with you the calculator program compiled with pure javascript code, if you need a calculator program, you
