In JavaScript, Void is an operator that specifies that an expression is evaluated but does not return a value.The void operator uses the following format:1. javascript:void (expression)2. Javascript:void expressionExpression is a standard of Javascript to evaluate. Parentheses on the outside of the expression are optional, but writing is a good habit. (Implementation version Navigator 3.0)You use the void operator to specify a hyperlink. The expressio

I. The role of "#if 0/#if 1 ... #endif" 1 code is defined in a number of debug version codes, this time the code is completely ignored by the compiler. If you want code to take effect, just change #if 0 to #if 1. 2 #if 0 There is also an important use for annotations, if you want to annotate the program is very long,

When we use ASP to develop the file upload function, in order to prevent users to upload trojan, often limit the upload of some files, commonly used method is to determine whether the extension of the upload file is consistent with the rules, you can use the right string function to remove the file name of the uploaded files after four, so it is easy to judge, But there is a loophole in it, very dangerous, is Chr (0) loophole, details please continue

Describes the comparison between a method of a string and a property to determine whether a string variable is empty, a string variable ' s ', and the following expression is faster? 1. String.IsNullOrEmpty (s) 2. S = = NULL | | s.length = 0 If you guess the second one, then you're right. It will be 15% faster than the String.IsNullOrEmpty method, but this is measured in one out of 10,000 seconds! Here's a simple example to compare 2 different ways: U

1. What did we get?ID, name, release year, release date, category, Director, starring, length, rating, star rating, number of reviews2. Make a classification of the data.A.. Basic information: Name, Director, release year, category, lengthB. Evaluation information: score, star rating, number of reviewsC. Starring table: starring (I'm struggling to make a single list)3. Table Design. Now a little bit of a sore is the primary key. Use the self-increment primary key or the movie ID key. After all m

1) Maximum approximate problem:For a given two positive integers, a, B, computes the number of approximately several numbers between a and a. For example: between a=1,b=36,1 and 36, the maximum number is 36, and the number is 9.Idea: The common method is to cycle tests between A and B each number exactly how many approximate, and then one by one comparison1 for the first time try:int number=0;//number of approximate numbersint flag=

Problem DescriptionBull and Ox is a kind of card game, a total of 5 cards, the rules are as follows:If the sum of the points of 3 cards cannot be found is a multiple of 10, then there is no bull;If the sum of the points of 3 cards is a multiple of 10, then there are cows, the remaining two card points and 10 to take the remainder, the remainder is a few, is the number of cows, especially when the remainder is 0 cattle cattle;For example: 1 2 3 4 5, 1

Original: What does the settimeout (fn,0) under JavaScript mean?I'm very sensitive to settimeout and stuff like that in the recent study of asynchronous programming. On the segmentfault saw a problem "about settimeout time set to 0 o'clock": the questioner read an article, the original explanation of the SetTimeout delay time is 0 when things will happen, the que

First, let's look at an example: Copy Code code as follows: Document.forms[0] When you have a form form or multiple form forms in an HTML page, you return a form array of nodelist typesDocument.forms[0].usernames, here the usernames can be the value of the ID, or the value of name, where the two properties are equivalent. Also, it does not distinguish between a text box, a radio box,

One, I am a little white The second half more impetuous, have a good meditation study, farewell to small white. Decisively bought a few books: Among them, the first to see the "JavaScript mode"-many people think very shi a book. ...... Evaluation Impressions, etc. 500 words omitted ... When I see the end of chapter two, once again saw the "JS to avoid using void" view, so, to hook up as a small white I have long been a problem: "Since JS is void not recommended, then why Sina Weibo, Taobao
