Why do you want to initialize CSS?CSS initialization refers to the style of resetting the browser (that is, reset.css). The default styles for different browsers may vary, so the first thing to develop is how to unify them. If you do not initialize CSS, there will often be page differences between browsers. Each time the new development site or new Web page by initializing CSS style properties, for we will use the CSS or HTML tags more convenient and accurate, so that we develop the content of t

It's a long time to explain JavaScript inheritance. If you don't talk nonsense, go to the topic.Now that you want to learn about inheritance, it proves that you have a certain understanding of JavaScript object-oriented. If you have any questions, refer to the basic knowledge of object-oriented in JavaScript, next, we will generally use these methods to inherit JavaScript.Prototype chainThe simplest way to implement inheritance in JavaScript is to use the prototype chain to direct the pr
A good explanation of JavaScript inheritance, but slow to explain now. Don't say much nonsense, go straight to the chase.Since you want to understand the inheritance, prove that you have a certain understanding of JavaScript object-oriented, such as what is not understood can refer to the "Object-oriented JS basic explanation, Factory mode, constructor mode, prototype mode, mixed mode, dynamic prototype mode", The next step is to complete the JavaScript inheritance through those methods.

So far, the five major sorting algorithms have been summarized:
1. Insert Sort
2, bubble sort, select sort, Exchange sort (to classify these three methods as their ideas are essentially the same)
3. Merge sort
4, Heap sorting
5. Quick Sort
The above five sorts can be called "comparison sort", as the name suggests, because they are based on the comparison elements to determine their relative position.
The first two of the time are O (n^2), merge sort and heap sort worst O (n

In many applications very large integers numbers is required. Some of these applications is using keys for secure transmission of data, encryption, etc. In this problem you is given a number, you has to determine the number of digits in the factorial of the number.
In many applications, you need to use very large integers. Some of these applications are using keys for secure data transfer, encryption, and so on. In this problem, you get a number, you have to determine th
magnitude (or amplitude) of the comparison, that is to say, such as 2n and 28n isMagnitude (magnitude of change) equivalent.There are three different scenarios:
F (n)
i.e. f (n) = O (nlogba-e), E > 0 is any small constantOr, f (n) changes slower than Nlogba, slow NESo, T (n) îq (Nlogba)
F (n) > Nlogba
i.e. f (n) = W (Nlogba +e), E > 0 is any small constantOr, f (n) changes faster than Nlogba, NESo, T (n) îq (f (n))
It can be simply said that the two items on the right side of the recursive equ

In today's work, we need to dynamically generate HTML code on the page, but find that the click event of the newly generated code is invalidated (the non-dynamically generated code has already bound the Click event), so there are many solutions on the web, many more complex, and the use of jquery is relatively old, So combined with their own tests on the Internet, found a solution.I used the jquery is 1.9.11,jquery1.7 after the live method discarded, the new on and off method, my solution is to

Agreed to explain the JavaScript inheritance, but delayed to now explain. No more nonsense, go straight to the point.
Since you want to understand the inheritance, prove that you have a certain understanding of JavaScript-oriented objects, such as what you do not understand can refer to the object-oriented JS Basic explanation, Factory mode, constructor mode, prototype mode, mixed mode, dynamic prototype mode, The next step is to finish the JavaScript inheritance in general by those methods.
