VaR color = new dojo. Graphics. color. color (, 0); // defines a black color object.
VaR color = new dojo. Graphics. color. color (1.0, 0,); // defines a black color object.
VaR color = new dojo. Graphics. color. color ([1.0, 0,]); // defines a black color object
VaR color = new dojo. Graphics. color. color ('rgb (, 0) '); // defines a black color object.
VaR color = new dojo. Graphics. color. color ('#000000'); // defines a black color object.

Dojo. Graphics. color. color. torgb

Usage example:

Color. torgb (); // returns an array of [0, 0]
Color. torgb (true); // returns an array of [1.0, 0 ,]

Dojo. Graphics. color. color. torgba

Usage example:

Color. torgba (); // returns an array of [1.0, 0 ,]

Dojo. Graphics. color. color. tohex
Dojo. Graphics. color. color. tostring

Color. tohex (); // return "#000000"
Color. tostring (); // return "#000000"

Dojo. Graphics. color. color. tocss

Dojo. Graphics. color. color. Blend

Mix another color to get a new color

Usage example:

Color. blend ('# ffff', 1); // Returns [255,255,255]
Color. blend ('# ffffff',-1); // return [0, 0]
Color. blend ('# ffffff', 0); // mix the black and white colors by the ratio of 1 to 1. the return value is [127,127,127].
Color parameters can be any color format, such as arrays and strings.

Or

Dojo. Graphics. color. blend ([0, 0], [255,255,255], 0); // will return [127,127,127]
Dojo. Graphics. color. blend ("#000000", "# ffffff", 0); // will return "# 7f7f7f"
If the first parameter is a string, the return value also returns a string.

Dojo. Graphics. color. color. blendhex

Dojo. Graphics. color. blendhex ("#000000", "# ffffff", 0); // will return "# 7f7f7f"

Dojo. Graphics. color. extractrgb

Convert input to RGB Array

Module: dojo. Uri. Uri

Dojo. Uri. Uri

A class dedicated to uri (Uniform Resource Identifier) processing.

Usage example:

Uri = (new dojo. uri. uri ("http: // myserver/dojo/", "guide.html ")). tostring (); // URI will be "http: // myserver/dojo/guide.html"
Uri = (new dojo. uri. uri ("http: // myserver/dojo /",".. /guide.html ")). tostring (); // URI will be "http: // myserver/guide.html"

The URI syntax defined by RFC: [scheme:] [// authority] [path] [? Query] [# fragment]
Authority Syntax: [user-Info @] host [: Port]

For example, we define a URI

VaR uri = new dojo. Uri. Uri ("http: // User: password @ myserver: 80/dojo/", "guide.html? Page = 1 # Top ");

The URI attributes are as follows:

Authority: Server Name "User: password @ myserver: 80"
Fragment: fragment name "TOP"
HOST: Host Name "myserver"
Password: Password "password"
Path: path "/dojo/guide.html"
Port: Port 80
Query: parameter "page = 1"
Scheme: mode "HTTP"
Uri: complete address "http: // User: password @ myserver: 80/dojo/guide.html? Page = 1"
User: username "User:" seems a bit problematic, with a colon
