annoying thing in JavaScript is that the variable has no scope of use. All variables, functions, arrays, and objects are considered global as long as they are not inside the function. That is to say, other scripts on this page can also access it, and overwrite it. The solution is to put your variable inside an anonymous function and call it immediately after definition. For example, the following statement generates three global variables and two global functions:Copy codeThe Code is as follows

amount of network traffic. If not required, it is not appropriate to transmit data tables containing dozens of or hundreds of data via webservice.　　Then, as far as the problem itself is concerned, the dataset type returned by. NET WebServices can be parsed directly by other non-. NET clients, because even the return value of the dataset type is expressed in XML format for transmission. The following example is a WebMethod with a return type of dataset and the XML format data returned after it i

solution is to put your variable inside an anonymous function and call it immediately after the definition is complete.For example, the following syntax will produce three global variables and two global functions:var name = ' Chris ';var age = ' 34 ';var status = ' single ';function Createmember () {//[...]}function Getmemberdetails () {//[...]}If there is a variable called in the other scripts on this page status , the trouble arises.If we encapsul

Semantic URL attack Curiosity is the main motive of many attackers, and semantic URL attacks are a good example. This type of attack mainly involves editing the URL to find something interesting. For example, if a user Chris clicked on a link in your software and reached the page http://www.php.cn/, it would be natural for him to try to change the user's value to see what would happen. For example, he might visit http://www.php.cn/to see if he can rea

Awk is a programming language dedicated for text processing. yes, it is a programming language. It only serves text processing, so you cannot use it to write system software or scientific computing (of course, it can also do mathematical computing ), it can only be used for text processing. unlike SED, awk has the programming language features, including built-in functions, logical statements, and input and output statements. In fact, it looks like a C language, but all the functions are concent

The library was launched in 2007, and Timothy has published a blog on the transparency of irregular windows and letter masks. The main problem with the first method is to useRobotClass. Even if you have the permission to get the screen, you must complete it before the display window. In addition, ho

recommend some toolkit. The benefit of this method is not limited to reducing multiple event processors to one. For example, you need to dynamically append more links to the chain table. After event delegation, you do not need to make other modifications. Otherwise, you need to recycle the chain table and re-install the event processor for each link. Anonymous functions and modularity The most annoying thing in JavaScript is that the variable has no scope of use. All variables, functions, array

NET web services can be directly returned by other non. net client resolution, because even the dataset type return value, will be reached by the table XML format and then transmitted.
