Read the data from the database, and then display the data in XML format, but prompted Hd,category,subsort and so did not close, but I have closed ah, I do not know what is the specific reason for this problem? VB Code: Copy Code code as follows: Response. Contenttype= "Text/xml" Response.Charset = "GB2312" Response.Expires = 0 Response.Write " Response.Write vbcrlf " Response.Write vbcrlfvbtab amp; " Response.Write vbcr

Closure of four concepts, execution environment, activity object, scope, scope chainWhen a function is defined, the scope of the function is determined, the entire function body is the execution environment, if the function is a global function, then its scope chain as long as the Window object, when the function is called, an active object is created, the arguments property is added to the active object, When a child function (nested function) accesses a variable, it is searched from its own ac

18th, Max in the global context environment is assigned a value of 100. Such as:Fourth, executes to line 20th, executes F1 (15), that is, executes bar (15), creates a bar (15) context, and sets it to the active state.When you execute bar (15), Max is a free variable and needs to be found in the scope where the bar function was created, and the value of Max is 10. This process has been mentioned in the scope chain section.The point here is that creating the bar function is created when you execu

; function bbb () { a++; alert (a); } function CCC () { a++; alert (a); } return { b:bbb, //json structure C:ccc } })(); Alert (AAA.A)//undefined AAA.B (); //2 AAA.C () //3 Summarize:1. Closures are functions that have access to variables in another function scope, and the most common way to create closures is to create another function within one function and access the local variables of the function through another function. The disadvantage of closure

The scope of a variableThe special point of the JavaScript language is that the global variables can be read directly inside the function.On the other hand, a local variable inside a function cannot be read naturally outside the function.Function F1 () {var n=999;}alert (n); ErrorSecond, how to read the local variables from the outside?For a variety of reasons, we sometimes need to get local variables within the function. However, as already mentioned, under normal circumstances, this can not be

The example in this article analyzes the channel that closes a buffer in the go language. Share to everyone for your reference. The specific analysis is as follows: The go language offers two channels, with buffers and no buffers. Channels without buffers, send and receive are synchronized, must receive the receiver of the message, the sender can be freed from the sending call. A channel with a buffer, before the buffer is full, the send and receive are asynchronous, and the sending operation o
