Use zoom, overflow to resolve floating problems for nested containers under IE6, IE7, FFwe often come across a container. A border is set, and the height of the border varies with the container height, but when the container is set to a floating property, the bounding box does not follow the change, and the float needs to be cleare
that the subroutine should be placed in another class central and then called in the original class.11. excessive use of basic data types12. A class is idle , and sometimes refactoring of code can cause an existing class to have nothing to do. If a class looks like a misnomer, you should consider whether to pass the functionality of the class to other classes and then completely delete the class.13. a series of sub-procedures for transmitting data14,

At the end of 16, the maintenance of an old project was followed up, because the project was developed earlier and you know the various ways to do it. In the familiar with the code and in the follow-up to some specific tasks, often found that some code is not conducive to reading comprehension and add new features, if only one or two lines of code, I directly changed, but some longer code, because the time relationship is expected to be delivered as soon as possible, the
Recently read the "HTML refactoring" this book, the following to make their own summary, we can learn to communicate together.What is refactoring? Refactoring is a process in which code is gradually perfected without changing the behavior of the program, and usually requires some help from the automation tools. A good site is a need for us to make perfect impro

Next, let's take a look at what is in the System Reconstruction toolbox, that is, to see what methods are available for system reconstruction. System refactoring always adjusts our code at different levels, so the refactoring method is divided into multiple layers. In general, the reconstruction methods are divided into the following layers: reconstruction of methods, objects
Code refactoring has become a frequent issue. Since Martin Fowler's book refactoring, it has been around for ten years. Many programmers have become familiar with refactoring. However, whenever we face project pressure, we often leave the reconstruction behind and leave it out of the 9th cloud. There are enough reasons to explain: the function is not complete. Wh
When we begin to refactor the system, we do not start to modify the code, but first establish the test mechanism. No matter what the program, as long as we are modified, theoretically can introduce bugs, so we have to test. Since it's a test, you have to have a right or wrong standard of judgment. In previous tests, the criteria for their evaluation were whether they met business needs. As a result, testers often always hold the requirements document testing system.
Unlike previous code modific
Whether in the iphone development or learning process will see some not very ideal code, it is undeniable that they are constantly "contributing" to this kind of code. In the face of some code "bad taste", refactoring is obviously an effective way to solve. The "reconstruction of the iphone" series wanted to summarize and supplement some of the refactoring that was going on in the development of the iphone,
LZ has been studying the Virtual Machine Source Code recently. Unfortunately, it's just a little bit of a clue. I can't share it with you. The huge Java Virtual Machine source code is really not something that can be done overnight, and LZ is excited.
Aside from the relatively underlying Java Virtual Machine source code, LZ will discuss with you a few tips on code refactoring. This content is partly from books, it is partly from some practical experie

I remember that when I was in college, oo thought like a popular song. As long as I was a computer student, I could say that I was a good guy. You may ask what Oo is. At that time, we (mostly) talked about
Recently in the "refactoring to improve the existing code design" This book, some sentiment to share to everyone!! This sentiment all own blind thought, said the wrong please forgive me!!This book I have seen the 6th chapter, the first 5 chapters can be briefly summed up as: "Why Refactor?" How to Refactor? (Methods, principles of refactoring) "The book mentions "nothing but three or three
PrefaceSome of the previous blogs have said rewriting and overloading, and today it is mainly about refactoring, by the way, by comparing the three.Refactoring , overriding, overloadingReconstruction is to improve the quality and performance of the software by adjusting the program code, so that the design pattern and architecture of the program are more reasonable, and the expansibility and maintainability of the software are improved. in layman's te
Application ScenariosI believe you have encountered this scenario:There are already a bunch of if-else or switch-case in the old code, and the product requires adding a new function to the process.What do people do at this time?My advice is to:
Refactor this piece of code. On the basis of refactoring, new functions are added.
Someone will say:
The duration of the original tense, and then re-construction of the old code, will not
Today, we do not introduce specific refactoring techniques. Let's take a moment to look back and summarize what kind of code needs to be refactored and what kind of code has an "unpleasant smell" to suggest that we need refactoring to suggest that this code actually has an improvement. I also like the author of the code that the characteristics of the use of "bad taste", very image is also very vivid. Below
Today's refactoring has no fixed form. I have used different versions over the years, and I bet different people will have different versions. This refactoring applies to scenarios where the switch statement block is large and new judgment conditions are introduced at any time. In this case, we recommend that you use the policy mode to encapsulate each condition into a separate class. There are many ways to
