jQuery颜色选取器插件COLPICK

插件官网：http://www.jq22.com/jquery-info367

下载该插件和 colpick.js 和 colpick.css 添加到您的文档的头：

<script src="js/colpick.js" type="text/javascript"></script><link rel="stylesheet" href="css/colpick.css" type="text/css"/>

现在你可能会在任何 jQuery 对象来创建一个颜色选取器上调用colpick方法。默认情况下您获取下拉列表颜色选择器：

html

<button id="picker">Show Color Picker</button>

js

$('#picker').colpick();

选项

传递给 colpick 函数作为对象的几个选项允许您自定义颜色选择器。例如，传递flat:true使颜色选取器总是可见的如下面的示例。

html

<div id="picker"></div>

JS

$('#picker').colpick({    flat:true,    layout:'hex',    submit:0});

All the available options are:

OptionTypeDescriptionflatbooleanFlat mode just displays the color picker in place, always visible, with no show/hide behavior. Use it withcolpickShow() and colpickHide() to define your own show/hide behavior or if you want the picker to be always visible. Default: falselayoutstringName of the color picker layout to use. Posible values are 'full' (RGB, HEX, and HSB fields), 'rgbhex' (no HSB fields) and hex (no HSB, no RGB). You can see the full layout at the top of the page. rgbhex and hex layouts are shown in theexamples below. Default: 'full'submitbooleanIf false the picker has no submit or OK button and no previous color viewer. If false useonChange function to get the picked color. Default: truecolorSchemestringThe color scheme to use for the picker, 'light' or 'dark'. Default: 'light'submitTextstringThe text to show on the submit button if active. Default: 'OK'colorstring or objectDefault color. Hex string (eg. 'ff0000') or object for RGB (eg. {r:255, g:0, b:0}) and HSB (eg. {h:0, s:100, b:100}). Default: '11ff00'showEventstringEvent that shows the color picker. Default: 'click'livePreviewbooleanIf true color values change live while the user moves a selector or types in a field. Turn it off to improve speed. Default: trueonBeforeShowfunctionCallback function triggered before the color picker is shown. Use it to define custom behavior. Should receive a colorpicker DOM object.onShowfunctionCallback function triggered when the color picker is shown. Use it to define custom behavior. Should receive a colorpicker DOM object.onHidefunctionCallback function triggered when the color picker is hidden. Use it to define custom behavior. Should receive a colorpicker DOM object.onChangefunctionCallback function triggered when the color is changed. This is the function thatallows you to get the color picked by the user whenever it changes, whithout the user pressing the OK button. Should receive:

• HSB object (eg. {h:0, s:100, b:100})
• HEX string (with no #)
• RGB object(eg. {r:255, g:0, b:0})
• el element, the parent element on which colorpicker() was called. Use it to modify this parent element on change (see first example below).
• bySetColor flag: if true, the onChange callback was fired by the colpickSetColor function and not by the user changing the color directly in the picker. There are some cases in which you'll want a different behaviour in this case (see last example).

onSubmitfunctionCallback function triggered when the color is chosen by the user, using the OK button. Should receive exactly the same as onChange. It's never fired if usingsubmit:0 option.

jQuery.fn Functions

These functions are the color picker's interface. Use them to control the color picker externally, but not to get color values. To retrieve color values from the picker use theonSubmit and onChange callbacks.

FunctionDescriptioncolpick(options)The main function used to create a color picker.colpickHide()Hides de color picker. Accepts no arguments. Use it to hide the picker with an external trigger.colpickShow()Shows the color picker. Accepts no arguments. Use it to show the picker with an external trigger.colpickSetColor(col,setCurrent)Use it to set the picker color. The onChange callback is fired with bySetColor set to true. Parameters:

• col: a hex string (eg. 'd78b5a') or object for RGB (eg. {r:255, g:0, b:0}) and HSB (eg. {h:150, s:50, b:50})
• setCurrent: If true the color picker's current color (the one to the right in layouts with submit button) is set in addition to the new color, which is always set.

jQuery Functions

The following functions are used internally by the color picker. However, they may also be required as utility functions by your application. They are made available as jQuery functions:

FunctionDescription$.colpick.rgbToHex(rgb)Receives an object like {r:255, g:0, b:0} and returns the corresponding HEX string (with no #).$.colpick.rgbToHsb(rgb)Receives an object like {r:255, g:0, b:0} and returns the corresponding HSB object (eg. {h:0, s:100, b:100}). HSB values are not rounded. H is in the [0,360] range, while S and B are in the [0,100] range.$.colpick.hsbToHex(hsb)Receives an object like {h:0, s:100, b:100} and returns the corresponding HEX string (with no #).$.colpick.hsbToRgb(hsb)Receives an object like {h:0, s:100, b:100} and returns the corresponding RGB object (eg. {r:255, g:0, b:0}). RGB values are whole numbers in the [0,255] range.$.colpick.hexToHsb(hex)Receives a hex string with no # and returns the corresponding HSB object (eg. {h:0, s:100, b:100}). HSB values are not rounded. H is in the [0,360] range, while S and B are in the [0,100] range.$.colpick.hexToRgb(hex)Receives a hex string with no # and returns the corresponding RGB object (eg. {r:255, g:0, b:0}). RGB values are whole numbers in the [0,255] range.

例子：

$(function(){$('#picker01').colpick({flat:true});$('#picker02').colpick({flat:true,colorScheme:'dark'});$('#picker1').colpick();$('#picker2').colpick({flat:true,layout:'hex',submit:0});$('#picker3').colpick({layout:'hex',colorScheme:'dark',submit:0,onChange:function(hsb,hex,rgb,el,bySetColor) {$(el).css('border-color','#'+hex);// Fill the text box just if the color was set using the picker, and not the colpickSetColor function.if(!bySetColor) $(el).val(hex);}}).keyup(function(){$(this).colpickSetColor(this.value);});$('.ex-color-box').colpick({colorScheme:'dark',layout:'rgbhex',color:'ff8800',livePreview:0,onSubmit:function(hsb,hex,rgb,el) {$(el).css('background-color', '#'+hex);$(el).colpickHide();}}).css('background-color', '#ff8800');});
