angular global variable

A global variable for PHP if the address of a local variable is referenced $b = "DASDF";Function abc () {$a = "ABC";Global $b;$b = $a;echo $b. " inner; ";}ABC ();echo $b. ";"; When I output B inside the function, it's ABC, but after we leave the function, output B, and revert to the initial value of DASDF, what's go

local variables and global variables in JavaScriptWe know that the variables of JavaScript are loosely typed variables, that is, their variables only need to be declared with Var, the type of assignment is unqualified. Like what:var person=18;person= "Zhuzhenwei";That is, a value of type number is saved to person, and then a string type value is saved, but it is not recommended .Even we can assign a value directly to a

and function parameters.2. Heap refers to the memory blocks allocated by new. Their release compiler is not controlled and controlled by our application. Generally, a new compiler corresponds to a delete. If the programmer does not release the program, the operating system will automatically recycle it after the program is completed.3. The free storage zone is the memory blocks allocated by malloc and so on. It is very similar to the heap, but it uses free to end its own life.4. in the

types of variables, like the breed of puppies, may vary depending on the puppy lineage, some are smart, some will shop and so on. In many static languages, variables are specified at the time of definition and are not allowed to change during the course of a program, so if you have a puppy that can only be given a random breed, will it pull the wind? This is the case with PHP, which is a weakly typed language that can be arbitrarily assigned to any type of value. The value content. This is t

A global variable for PHP if the address of a local variable is referenced

Recently, I have seen some interesting information related to programs and memory. It can reflect the memory relationship between global data and local variables. The result I run on cygwin is that the stack space is only 2 MB. After it is used up, the program stops running. The source code is as follows: Filename: depletestacksize. c# Include Static long stack_block_header; Void depletestackspace () {// declare local

Have not noticed this hole, today read "You do not know the JavaScript" mentioned in the future need to pay attention to.The id attribute in the DOM adds a variable of ID value to the global variable

Original blog, reprint please indicate the source--Zhou Xuewei http://www.cnblogs.com/zxouxuewei/Static is used in two ways: static in process-oriented programming and static in object-oriented programming. The former applies to ordinary variables and functions, and does not involve classes; the latter mainly describes the role of static in classes.I. For static in process designC + + variables can be divided into 6 different scopes according to the different lifecycles of the defined locations:

JavaScript -- Item5 global variable that you don't know1. Use as few global objects as possible The problem with global variables is that your JavaScript Application and all the code on the Web page share these global variables. They live in the same

If you only want to know the conclusion: $scope. $watch ($rootScope. Xxx,function (newval,oldval) { //do something }) Someone immediately asks why not: $rootScope. $watch ("xxx", function (newval,oldval) { //do something }) From one of my recent bugs, why use the first method. Logic as pictured, I used the $rootScope. $watch in the beginning. Because the Angularjs on the $rootScope watch once registered globally valid. And my globa
