Looking for a long time, found little information on the internet, so want to write their own hands, slowly found many problems, their own algorithm, write a short calculation formula is OK, long on the hang, and then long I am afraid to panic.
One day do MySQL suddenly found that the original MySQL function so powerful, you can directly calculate the string ... Haha, this will be happy.
The code is also super simple to do an AJAX calculator

Idle to do nothing, learn to learn the development of graphical interface, maybe when you write something, there will be very practical value.
Never wondered how to get other property values, such as text boxes, when the button was clicked.
Today, I saw the horse soldier Teacher's video, through a façade mode method, add the required classes to their own member variables, such as the text box belongs to the class injected into the button listener class properties, you can easily get all the publ
The calculator has recently been perfected, added support for variables, added more functions, implemented logical short-circuit operations, and fixed some minor bugs. I remember seeing an example in a book before, enter a function expression, you can draw the waveform of the function. When you first learn VB, you like to use a function to paint. Coupled with a little interest in electronic technology, many waveforms can be expressed using functions,
Array this is my code, please help me see if there is a problem: (I'm going to use an array as a calculator)

Recently I used javascript to write a simple calculator. It seems okay to test it myself. The Code has been commented out. It is very good. I suggest you learn it. 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
