4. Replace the string with only the first match
The following code:
In fact, the result is "This_is a title". In JavaScript, the first parameter of String. replace should be a regular expression. Therefore, the correct method is as follows:
Var fileName = "This is a title". replace (// g ,"_");

From nine JavaScript gotchas, the following are nine traps that JavaScript is prone to mistakes. Although it is not a very profound technical problem, please note that it will make your programming easier, that is, make life easier. I will give some comments on some traps.

From nine JavaScript gotchas, here are nine pitfalls that JavaScript is prone to make mistakes. While not a very advanced technical issue, note that it will make your programming a little easier, known as making life easier. I will mix some comments on some pitfalls.1. Last commaAs in this code, note the last comma, which should be good in linguistics (Python's similar data type dictionary, dictionary, is allowed). IE will report grammatical errors, but vague, you can only scan from thousands of
long run, it is a profound knowledge to add linguistic features into the mystery of C + + and observe it. Now judge is a very simple thing, say what C + + sucks, design too bad and so on. When there is no understanding of the constraints on C + + design, many people blurt it out. Stroustrup (51CTO Editor's note: This Stroustrup is to invite the author to participate in the Stroustrup, that is, the C + + language designer Stroustrup) constraints are,

more like an abstract class, because it can not only have abstract methods, but also have specific implementations. However, this statement is too one-sided. After all, the interface still cannot possess the State, while the abstract class can hold the State. At the same time, from the inheritance point of view, a class can implement multiple interfaces, and a class can only inherit one class at most.Use Lambda expressions to create smoother APIsFor example, there is a type for sending mail and
