WAJAF for GO v0.1

WAJAF is the WebAbility Javascript Application Framework. It is a synchronized GO-Server <=> JS-Client framework to develop organized web applications.

GO manuals are available on godoc.org GoDoc

JAVASCRIPT manual:

The examples and tests show the working functions and the manual of them.

![Go to Examples]

  1. The main core.

The main core contains:

  • 2 attributes:

Examples & manuals: ![Go to attributes examples]

  • zIndex method, used to set an unused zIndex to a node,

Examples & manuals: ![Go to core examples]

  • Verification methods is*, used to know the type of JS objects. All the functions return true/false. True means the variable match the specified type by the is* method. -- isDefined: returns true if the variable is not undefined. -- isEmpty: returns true if the variable is empty: empty means undefined, null, empty array or empty string. -- isBool: returns true if the variable is a boolean. -- isNumber: returns true if the variable is number, integer or float. -- isString: returns true if the variable is a string or a String object. -- isArray: returns true if the variable is an array. -- isObject: returns true if the variable is an object. It includes String(), Date(), {}. etc. Note than Javasript consider null as an object too. -- isFunction: returns true if the variable is a function. -- isDate: return true if the variable is a Date object. -- isDOM: return true if the variable is a DOM node object.

Examples & manuals: ![Go to examples]

  • Objects and nodes methods.

For objects:

  • WA.extend: Will extends an object from another (inheritance).
  • WA.clone: Will clone an object and all its children. -- If you dont care the type of object but only its attributes, you can use WA.clone(object, true) -- If you use the normal method WA.clone(object), it will close the whole object with attributes and methods.
  • WA.sizeof: Will calculates the size (number of attributes) of an object.

For DOM nodes:

  • WA.createDomNode: Will create a DOM Node of specified type, and apply classname if defined.
  • WA.getDomNode: Will get the DOM node of the specified Id.
  • WA.toDOM: Will get the DOM node from a string ID or a node itself.

Examples & manuals: ![Go to examples]

  • Node get() functions.

The get function lets you find a node or a set of nodes by rules, then apply some changes on the node.

The get() method works as followed:

  1. The code will search all the nodes corresponding to the filter you give it.

There are 3 posibilities:

a - No nodes were found. The subsequent operations will do nothing. b - There was only one node found. The subsequent operations will work directly on this node. c - There was more than 1 node found (from 2 to the whole DOM). The subsequent operations will work for each one of the found nodes.

  1. The operation is applied to all the node(s).

  2. The operations can be chained.

The parameter of get() method is a string used to search the nodes:

"#id": If you want to find a single node by its unique id, using the CSS syntax. ".class": If you want to find a list of nodes by their class, using the CSS syntax. "!name": If you want to find a list of nodes by their name (in a form). "tag": If you want to find a list of nodes by their tag type (example: 'div', 'a').

TO DO:

  • Adds local specific functions to all the Containers, Elements, Zones, etc to improve tree programmation.
  • Tests
