Zesk JavaScript tools

Introduction

Zesk provides a front-end JavaScript library which contains useful tools which mimic much of the built-in tools available in Zesk's PHP library. When possible, semantics are as similar as possible between the JavaScript version of a function and the equivalent PHP version.

As well, note that all Zesk JavaScript depend on having jQuery present.

Functions

Type functions

• boolean is_bool(value) - Returns true if value is a JavaScript boolean
• boolean is_numeric(value) - Returns true if vaue is an JavaScript number
• boolean is_string(value) - Returns true if vaue is a JavaScript string
• boolean is_array(value) - Returns true if vaue is a JavaScript array
• boolean is_object(value) - Returns true if vaue is a JavaScript object
• boolean is_integer(value) - Returns true if vaue is an integer
• boolean is_function(value) - Returns true if vaue is a JavaScript function
• boolean is_float(value) - Returns true if vaue is a floating point number
• boolean is_date(value) - Returns true if vaue is a JavaScript Date
• boolean is_url(value) - Returns true if vaue is a URL string
• string gettype(value) - Returns the type of object

html tools - Generation/Manipulation of HTML code

String html.encode(String html) Encode HTML

Like PHP's htmlspecialchars, used to encode attributes for HTML tags

String html.decode(String html) Decode HTML

Reverse of html.encode - converts HTML entities into text values.

String html.to_attributes(mixed attributes) Convert attributes into attributes Object

Takes a string or object parameter and returns an Object which is that

String html.attributes(Object attributes) Convert Object to HTML attributes string

Convert object to a string which can be used as attributes in an HTML tag.

String html.tag(string type, [ mixed attributes, ] string value) Generate HTML tag (with attributes)

This first form receives two parameters, the tag type, and the value within the tag:

$(elem).html(html.tag("strong", "There will be bold."));

The second form extends the function to support optional HTML attributes as the 2nd parameter.

zesk tools - Global state and settings

string zesk.query_get(name, default)

Retrieve a query string parameter name or return default if not found.

string zesk.get_path(path, default)

Sets Zesk Settings value within the global state. Module information is stored in:

modules.module_name.value1

So, for the module "dropfile", the values are stored:

modules.dropfile.

string zesk.setPath(path, value)

Get Zesk Settings value within the global state.
