DP_Debug:
Working with Custom Objects

Back to the Main Page

All of these examples assume that the library has been imported as noted in the Documentation.

While dump is useful with system object it really begins to shine when used to get the current state of your custom objects and information structures.

A Date

Assuming the following JavaScript object declaration:

	MyDate = new Date();

You can:

• Dump the date: DP_Debug.dump(MyDate);
• See DP_Debug.getType(MyDate) compared to typeof MyDate.

A String

Assuming the following JavaScript object declaration:

	MyString = new String("Hello World!");

You can:

• Dump the string: DP_Debug.dump(MyString);
• See DP_Debug.getType(MyString) compared to typeof MyString.

A Simple Array

Assuming the following JavaScript array declaration:

	MyArray = [1,2,3,4,5];

You can:

• Dump the array: DP_Debug.dump(MyArray);
• Dump the array with a label: DP_Debug.dump(MyArray, 'MyArray');
• See DP_Debug.getType(MyArray) compared to typeof MyArray.

A Simple Object

Assuming the following JavaScript object declaration:

	MyObject = {Prop1: "Value1", Prop2: "Value2"};

You can:

• Dump the object: DP_Debug.dump(MyObject);
• Dump the object with a label: DP_Debug.dump(MyObject, "MyObject");
• Dump the object to see both properties and user-defined methods (functions): DP_Debug.dump(MyObject, 'With Functions', true)

A Complex, Nested Object

Here we'll create a simple representation of a family: a married couple and two children. Note that the object contains recursive references: "John" and "Jill" reference each other as spouse.

Assuming the following JavaScript object declarations:

	Person1 =
	{	FirstName: "John",
		LastName: "Smith",
		Birthday: new Date(1970,04,23),
		Married: true
	}

	Person2 =
	{	FirstName: "Jill",
		LastName: "Smith",
		Birthday: new Date(1972,02,12),
		Married: true
	}

	Person3 =
	{	FirstName: "Timmy",
		LastName: "Smith",
		Birthday: new Date(2002,10,25),
		Married: false
	}

	Person4 =
	{	FirstName: "Susie",
		LastName: "Smith",
		Birthday: new Date(2000,01,04),
		Married: false
	}

	Person1.Spouse = Person2;
	Person2.Spouse = Person1;
	Person1.Children = [ Person3, Person4 ];
	Person2.Children = [ Person3, Person4 ];

	Family = [Person1, Person2, Person3, Person4];

You can:

• Dump Person4 ("Susie"): DP_Debug.dump(Person4);
• Dump Person1 ("Jack"): DP_Debug.dump(Person1);
• Dump Family: DP_Debug.dump(Family);
