User · Answer

You can get the property the same way as you set it   foo      bar   value      You set the value foo  bar      baz    To get the value foo  bar    will return  baz

When you create an object myObj as you have  think of it more like a dictionary  In this case  it has two keys  name  and age   You can access these dictionaries in two ways    Like an array  e g  myObj name    or Like a property  e g  myObj name   do note that some properties are reserved  so the first method is preferred    You should be able to access it as a property without any problems  However  to access it as an array  you ll need to treat the key like a string   myObj  name     Otherwise  javascript will assume that name is a variable  and since you haven t created  a variable called name  it won t be able to access the key you re expecting

You could also create something that would be similar to a value object  vo    SomeModelClassNameVO js   function SomeModelClassNameVO name id        this name   name      this id   id      Than you can just do      var someModelClassNameVO   new someModelClassNameVO  name  1      console log someModelClassNameVO name

myObj prop    value    That should work  You mixed up the name of the variable and its value  But indexing an object with strings to get at its properties works fine in JavaScript

User · Answer

simple as this myObj name   value

User · Answer

myObj name value   or  myObj  name   value      Quotes are required    Both of these are interchangeable   Edit  I m guessing you meant myObj prop    value  instead of myObj name    value  Second syntax works fine  http   jsfiddle net waitinforatrain dNjvb 1
