Dojo學(xué)習(xí)筆記(9. dojo.graphics.color & dojo.uri.Uri)
模塊：dojo.graphics.color
下面是dojo里定義的顏色名稱
dojo.graphics.color.named.white //白色
dojo.graphics.color.named.black //黑色
dojo.graphics.color.named.red //紅色
dojo.graphics.color.named.green //綠色
dojo.graphics.color.named.blue //藍(lán)色
dojo.graphics.color.named.navy //海軍藍(lán)
dojo.graphics.color.named.gray //灰色
dojo.graphics.color.named.silver//銀色
dojo.graphics.color.Color
顏色類
Usage Example:
var color = new dojo.graphics.color.Color(dojo.graphics.color.named.black); //定義一個(gè)黑色的顏色對(duì)象
var color = new dojo.graphics.color.Color(0,0,0); //定義一個(gè)黑色的顏色對(duì)象
var color = new dojo.graphics.color.Color(0,0,0,1.0); //定義一個(gè)黑色的顏色對(duì)象
var color = new dojo.graphics.color.Color([0,0,0,1.0]); //定義一個(gè)黑色的顏色對(duì)象
var color = new dojo.graphics.color.Color('rgb(0,0,0)'); //定義一個(gè)黑色的顏色對(duì)象
var color = new dojo.graphics.color.Color('#000000'); //定義一個(gè)黑色的顏色對(duì)象
dojo.graphics.color.Color.toRgb
Usage Example:
color.toRgb(); //返回一個(gè)[0,0,0]的數(shù)組
color.toRgb(true); //返回一個(gè)[0,0,0,1.0]的數(shù)組
dojo.graphics.color.Color.toRgba
Usage Example:
color.toRgba(); //返回一個(gè)[0,0,0,1.0]的數(shù)組
dojo.graphics.color.Color.toHex
dojo.graphics.color.Color.toString
Usage Example:
color.toHex(); //返回"#000000"
color.toString(); //返回"#000000"
dojo.graphics.color.Color.toCss
Usage Example:
color.toCss(); //返回"rgb(0,0,0)"
dojo.graphics.color.Color.blend
混合另一個(gè)顏色得到一個(gè)新顏色
Usage Example:
color.blend('#ffffff', 1); //返回[255,255,255]
color.blend('#ffffff', -1); //返回[0,0,0]
color.blend('#ffffff', 0); //按1比1混合黑色和白色，返回[127,127,127]
顏色參數(shù)可以為顏色的任意形式，比如數(shù)組，字符串等
or
dojo.graphics.color.blend([0,0,0], [255,255,255], 0); //will return [127,127,127]
dojo.graphics.color.blend("#000000", "#ffffff", 0); //will return "#7f7f7f"
若第一個(gè)參數(shù)為字符串，則返回值也會(huì)返回字符串
dojo.graphics.color.Color.blendHex
Usage Example:
dojo.graphics.color.blendHex("#000000", "#ffffff", 0); //will return "#7f7f7f"
dojo.graphics.color.extractRGB
將輸入轉(zhuǎn)換為RGB數(shù)組
dojo.graphics.color.hex2rgb
將輸入的字符串轉(zhuǎn)換為RGB數(shù)組
dojo.graphics.color.rgb2hex
將輸入的RGB數(shù)組轉(zhuǎn)換為字符串
dojo.graphics.color.Color.fromArray
Usage Example:
var color = dojo.graphics.color.Color.fromArray([0,0,0,1.0]);
模塊：dojo.uri.Uri
dojo.uri.Uri
專門(mén)用來(lái)處理URI(統(tǒng)一資源標(biāo)識(shí)符)的類
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"
RFC規(guī)定的URI語(yǔ)法：[scheme:][//authority][path][?query][#fragment]
authority語(yǔ)法：[user-info@]host[:port]
比如我們定義一個(gè)uri
var uri = new dojo.uri.Uri("http://user:password@myserver:80/dojo/", "guide.html?page=1#top");
則uri的屬性如下：
authority: 服務(wù)器名 "user:password@myserver:80"
fragment: 片斷名 "top"
host: 主機(jī)名 "myserver"
password: 密碼 "password"
path: 路徑 "/dojo/guide.html"
port: 端口 80
query: 參數(shù) "page=1"
scheme: 模式 "http"
uri: 完整的地址 "http://user:password@myserver:80/dojo/guide.html?page=1"
user: 用戶名 "user:" 似乎有點(diǎn)問(wèn)題，多了一個(gè)冒號(hào)
