want to set these methods to public. This time, namespace will be able to achieve your goal. First you have to define a namespace, (flashrek.as): Package flashrek.example{Public namespace flashrek= www.webjx.com;} The code in the Aaa.as file is then:Package flashrek.example{Import Flashrek.example.flashrek;public class AAA {function AAA () {var b:bbb=new BBB ();Flashrek::nstest ();}Flashrek function Nstest () {Trace ("namespace test");}}}Classes, nam

Now want to implement the following features: > 1, using a string to refer to the variable name. > For example, there are two variables a= "BBB" and bbb={"C": 1}, reference a how to get {"C": 1}, that is, a value of ' BBB ' is the value of the variable BBB. > Google, http://www.douban.com/group/topic/2193745/the follow

Fixed digits in asp.net with 0 functions (Resolved, example)! In the development, the number achieved 8 digits, but need to be filled with 0. such as: 123, said: 0000123. Examples are as follows: Decimal AAA = 123; Numeric type string bbb = AAA. ToString (); Convert to character BBB = bbb. PadLeft (7, ' 0 '); A total of 7, before using a 0-padd

JQuery exercises get objects (3)-Matching Based on attributes and content, and matching with form elements that contain id attributes, such as: $ ("span [id]") The Code is as follows: AAA BBB CCC DDD EEE FFF If the specified element does not contain the id attribute, for example, $ ("span: not (span [id])") or $ ("span: not ([id])") The Code is as follows: AAA BBB CCC DDD EEE FFF Contain

Delphi Tstrings is an abstract class, in the actual development, in addition to the basic types, the application of the most.General usage We all know, now to discuss some of its advanced usage.Let's start by listing several properties to be discussed:1, CommaText2, Delimiter Delimitedtext3, Names Values ValuefromindexLet's look at the first one: CommaText. How to use it? To speak in code:Constconstr:string = ' aaa,bbb,ccc,ddd ';VarStrs:tstrings;I:

script creates a Boolean object and converts it to a string: Script output: true. Let's take a look at the following example: var aaa = {i: 10,valueOf: function() { return this.i+30; },toString: function() { return this.valueOf()+10; }}alert(aaa > 20); // truealert(+aaa); // 40alert(aaa); // 50 This is because they secretly call the valueOf or toString method. But how can we tell which method is called? We can test it using another method. Because console. log is used, please experiment in FF

Probably......ObjectiveBasically, all JS data types have these two methods, except for NULL. They both solve the problem of JavaScript value operations and display, and overrides increase the optimizations they call.Test analysisLet's look at one example:var AAA = {I:10,Valueof:function () {return this.i+30;},Tostring:function () {return this.valueof () +10;}}Alert (AAA > 20); Truealert (+AAA); 40Alert (AAA); 50This results because they secretly invoke the valueof or ToString method.But how to d

shelve operation is used to temporarily store ongoing work to the perforce server, but does not submit a changelist.Shelve usage:When you perform multiple development tasks on some files at the same time (for example, you must first process jobs with higher priority or test on other platforms before submitting ).Or code review between developers before submission. P4 shelve is equivalent to attaching your modifications to the P4 server rack at zero time.P4 unshelve is equivalent to overwri
