Javascript pushing object into array

问题 Hey, I currently am having trouble trying to get this to work. Here's a sample code of what I am trying. A lot has been taken out, but this should still contain the problem. I have an object, user, and an array, player. I am trying to make an array with the players in it, here: function user(name, level, job, apparel) { this.name = name; this.state = "alive"; this.level = level; this.job = job; this.apparel = apparel; } player = new array(); player.push(new user("Main Player", 1, 1, "naked"))

QTP特点有哪些?

QTP特点有哪些? 浏览: 77 | 更新:2013-06-19 12:35 QTP是一个侧重于功能的回归自动化测试工具;提供了很多插件,如:.NET的,Java的,SAP的,Terminal Emulator的等等,分别用于各自类型的产品测试。默认提供Web,ActiveX和VB。 QTP支持的脚本语言是VBScript,这对于测试人员来说,感觉要“舒服”得多(如相比SilkTest采用C语言)。VBScript毕竟是一种松散的、非严格的、普及面很广的语言。 QTP支持录制和回放的功能。录制产生的脚本,可以拿来作为自己编写脚本的template。录制时,还支持一种lower level 功能,这个对于QTP不容易识别出来的对象有用,不过它是使用坐标来标识的,对于坐标位置频繁变动的对象,采用这种方式不可行。另外,QTP的编辑器支持两种视图:Keyword模式和Expert模式。Keyword模式想法是好的,提供一个 描述近似于原始测试用例的、跟代码无关的视图(我基本很少用,除了查看、管理当前test中各个action的完整流程),而Expert就是代码视图,一般编写脚本都在这个区域。 一个有用的工具:Object Spy,可以用来查看Run-time object和Test object属性和方法。 QTP通过三类属性来识别对象:a)Mandatory; b)Assitive; c

Why does perl object instance overwrite each other

问题 I've written some Perl code which compose two classes inherent from a base one. I suppose it would print something like this Mik: Meow! Meow! Sat: Woof! Woof! But it actually print this way: Sat: Woof! Woof! Sat: Woof! Woof! , package Animal; sub new { my $obj = shift; my $name = shift; our %pkg = ( 'name' => $name ); bless \%pkg, $obj; return \%pkg; } package Cat; @ISA = ("Animal"); sub new { my $obj = shift; my $name = shift; my $self = $obj->SUPER::new($name); return $self; } sub get_name

【CLR Via C#】第5章 基元类型、引用类型、值类型

  第二遍看这本书,决定记录一下加深印象。 值类型可以存储在堆和栈上,它是局部变量时存储在栈上,如果值类型是作为类的一个属性,那么就会存储在堆上; 引用类型有两块内存,一块存储引用地址(栈上),一块存储实际的对象(堆上)。 1,基元类型   什么事基元类型?基元类型是直接映射到FrameWork类库(FCL)中存在的类型,编译器直接支持的数据类型。比如int直接映射到System.Int32类型,就像是添加了using应用:using sbyte=System.SByte. C#基元类型 FCL类型 说明 sbyte System.SByte 有符号8位 byte System.Byte 无符号8位 short System.Int16 有符号16位 ushort System.UInt16 无符号16位 int System.Int32 有符号32位 uint System.UInt32 无符号32位 long Syetem.Int64 有符号64位 ulong System.Int64 无符号64位 char System.Char 16位Unicode字符 float System.Single 32位浮点值,即带小数 double System.Double 64位浮点值 bool System.Boolean True/False decimal [英] 'desɪml

Boolean.TRUE == myBoolean vs. Boolean.TRUE.equals(myBoolean)

问题 Is there ever a situation where using equals(Boolean) and == would return different results when dealing with Boolean objects? Boolean.TRUE == myBoolean; Boolean.TRUE.equals(myBoolean); I'm not thinking about primitive types here, just Boolean objects. 回答1: How about: System.out.println(new Boolean(true) == new Boolean(true)); System.out.println(new Boolean(true) == Boolean.TRUE); (both print false, for the same reason as any other type of objects). 回答2: It would be dangerous to use ==

js获取对象长度和名称

妖精的绣舞 提交于 2020-01-12 04:41:34
1.对象的长度不能用.length获取,用js原生的Object.keys可以获取到 var obj = {'name' : 'Tom' , 'sex' : 'male' , 'age' : '14'}; var arr = Object.keys(obj); console.log(arr); // ['name','sex','age'] console.log(arr.length); //3 2. javascript获取json对象的key名称的两种方法 第一种方法 jsonObj = { Name: ‘richard‘, Value: ‘8‘ } for (key in jsonObj){ console.log(key); //add your statement to get key value } 结果 Name Value 第二种方法 javascript中,Object具有一个key属性,可以返回json对象的key的数组 (Object has a property keys, returns an Array of keys from that Object) 用法: Object.keys(jsonObj) jsonObj = { Name: ‘richard‘, Value: ‘8‘ } console.log(Object.keys(jsonObj)
