Instructions & Help
The FAQ has instructions on asking for help, solutions to common problems, and how-to examples. First-time jQuery users can check out the Colorbox Beginner‘s Guide. Intermediate users can probably glean everything needed by view-source‘ing the demo pages.
Usage
Colorbox accepts settings from an object of key/value pairs, and can be assigned to any HTML element.
// Format:
$(selector).colorbox({key:value, key:value, key:value});
// Examples:
// Image links displayed as a group
$(‘a.gallery‘).colorbox({rel:‘gal‘});
// Ajax
$(‘a#login‘).colorbox();
// Called directly, without assignment to an element:
$.colorbox({href:"thankyou.html"});
// Called directly with HTML
$.colorbox({html:"<h1>Welcome</h1>"});
// Colorbox can accept a function in place of a static value:
$("a.gallery").colorbox({rel: ‘gal‘, title: function(){
var url = $(this).attr(‘href‘);
return ‘<a href="‘ + url + ‘" target="_blank">Open In New Window</a>‘;
}});
Settings
| Property | Default | Description |
|---|---|---|
| transition | "elastic" | The transition type. Can be set to "elastic", "fade", or "none". |
| speed | 350 | Sets the speed of the fade and elastic transitions, in milliseconds. |
| href | false | This can be used as an alternative anchor URL or to associate a URL for non-anchor elements such as images or form buttons. $("h1").colorbox({href:"welcome.html"}); |
| title | false | This can be used as an anchor title alternative for Colorbox. |
| rel | false | This can be used as an anchor rel alternative for Colorbox. This allows the user to group any combination of elements together for a gallery, or to override an existing rel so elements are not grouped together. $("a.gallery").colorbox({rel:"group1"}); Note: The value can also be set to ‘nofollow‘ to disable grouping. |
| scalePhotos | true | If true, and if maxWidth, maxHeight, innerWidth, innerHeight, width, or height have been defined, Colorbox will scale photos to fit within the those values. |
| scrolling | true | If false, Colorbox will hide scrollbars for overflowing content. This could be used on conjunction with the resize method (see below) for a smoother transition if you are appending content to an already open instance of Colorbox. |
| opacity | 0.85 | The overlay opacity level. Range: 0 to 1. |
| open | false | If true, Colorbox will immediately open. |
| returnFocus | true | If true, focus will be returned when Colorbox exits to the element it was launched from. |
| trapFocus | true | If true, keyboard focus will be limited to Colorbox‘s navigation and content. |
| fastIframe | true | If false, the loading graphic removal and onComplete event will be delayed until iframe‘s content has completely loaded. |
| preloading | true | Allows for preloading of ‘Next‘ and ‘Previous‘ content in a group, after the current content has finished loading. Set to false to disable. |
| overlayClose | true | If false, disables closing Colorbox by clicking on the background overlay. |
| escKey | true | If false, will disable closing colorbox on ‘esc‘ key press. |
| arrowKey | true | If false, will disable the left and right arrow keys from navigating between the items in a group. |
| loop | true | If false, will disable the ability to loop back to the beginning of the group when on the last element. |
| data | false | For submitting GET or POST values through an ajax request. The data property will act exactly like jQuery‘s .load() data argument, as Colorbox uses .load() for ajax handling. |
| className | false | Adds a given class to colorbox and the overlay. |
| fadeOut | 300 | Sets the fadeOut speed, in milliseconds, when closing Colorbox. |
| closeButton | true | Set to false to remove the close button. |
| Internationalization | ||
| current | "image {current} of {total}" | Text or HTML for the group counter while viewing a group. {current} and {total} are detected and replaced with actual numbers while Colorbox runs. |
| previous | "previous" | Text or HTML for the previous button while viewing a group. |
| next | "next" | Text or HTML for the next button while viewing a group. |
| close | "close" | Text or HTML for the close button. The ‘esc‘ key will also close Colorbox. |
| xhrError | "This content failed to load." | Error message given when ajax content for a given URL cannot be loaded. |
| imgError | "This image failed to load." | Error message given when a link to an image fails to load. |
| Content Type | ||
| iframe | false | If true, specifies that content should be displayed in an iFrame. |
| inline | false | If true, content from the current document can be displayed by passing the href property a jQuery selector, or jQuery object. |
| html | false | For displaying a string of HTML or text: $.colorbox({html:"<p>Hello</p>"}); |
| photo | false | If true, this setting forces Colorbox to display a link as a photo. Use this when automatic photo detection fails (such as using a url like ‘photo.php‘ instead of ‘photo.jpg‘) |
| ajax | This property isn‘t actually used as Colorbox assumes all hrefs should be treated as either ajax or photos, unless one of the other content types were specified. | |
| Dimensions | ||
| width | false | Set a fixed total width. This includes borders and buttons. Example: "100%", "500px", or 500 |
| height | false | Set a fixed total height. This includes borders and buttons. Example: "100%", "500px", or 500 |
| innerWidth | false | This is an alternative to ‘width‘ used to set a fixed inner width. This excludes borders and buttons. Example: "50%", "500px", or 500 |
| innerHeight | false | This is an alternative to ‘height‘ used to set a fixed inner height. This excludes borders and buttons. Example: "50%", "500px", or 500 |
| initialWidth | 300 | Set the initial width, prior to any content being loaded. |
| initialHeight | 100 | Set the initial height, prior to any content being loaded. |
| maxWidth | false | Set a maximum width for loaded content. Example: "100%", 500, "500px" |
| maxHeight | false | Set a maximum height for loaded content. Example: "100%", 500, "500px" |
| Slideshow | ||
| slideshow | false | If true, adds an automatic slideshow to a content group / gallery. |
| slideshowSpeed | 2500 | Sets the speed of the slideshow, in milliseconds. |
| slideshowAuto | true | If true, the slideshow will automatically start to play. |
| slideshowStart | "start slideshow" | Text for the slideshow start button. |
| slideshowStop | "stop slideshow" | Text for the slideshow stop button |
| Positioning | ||
| fixed | false | If true, Colorbox will be displayed in a fixed position within the visitor‘s viewport. This is unlike the default absolute positioning relative to the document. |
| top | false | Accepts a pixel or percent value (50, "50px", "10%"). Controls Colorbox‘s vertical positioning instead of using the default position of being centered in the viewport. |
| bottom | false | Accepts a pixel or percent value (50, "50px", "10%"). Controls Colorbox‘s vertical positioning instead of using the default position of being centered in the viewport. |
| left | false | Accepts a pixel or percent value (50, "50px", "10%"). Controls Colorbox‘s horizontal positioning instead of using the default position of being centered in the viewport. |
| right | false | Accepts a pixel or percent value (50, "50px", "10%"). Controls Colorbox‘s horizontal positioning instead of using the default position of being centered in the viewport. |
| reposition | true | Repositions Colorbox if the window‘s resize event is fired. |
| Retina Images | ||
| retinaImage | false | If true, Colorbox will scale down the current photo to match the screen‘s pixel ratio |
| retinaUrl | false | If true and the device has a high resolution display, Colorbox will replace the current photo‘s file extention with the retinaSuffix+extension |
| retinaSuffix | "@2x.$1" | If retinaUrl is true and the device has a high resolution display, the href value will have it‘s extention extended with this suffix. For example, the default value would change my-photo.jpg to [email protected] |
| Callbacks | ||
| onOpen | false | Callback that fires right before Colorbox begins to open. |
| onLoad | false | Callback that fires right before attempting to load the target content. |
| onComplete | false | Callback that fires right after loaded content is displayed. |
| onCleanup | false | Callback that fires at the start of the close process. |
| onClosed | false | Callback that fires once Colorbox is closed. |
Public Methods
| $.colorbox() | This method allows you to call Colorbox without having to assign it to an element. $.colorbox({href:"login.php"}); |
| $.colorbox.next() $.colorbox.prev() | These methods moves to the next and previous items in a group and are the same as pressing the ‘next‘ or ‘previous‘ buttons. |
| $.colorbox.close() | This method initiates the close sequence, which does not immediately complete. The lightbox will be completely closed only when the cbox_closed event / onClosed callback is fired. |
| $.colorbox.element() | This method is used to fetch the current HTML element that Colorbox is associated with. Returns a jQuery object containing the element. var $element = $.colorbox.element(); |
| $.colorbox.resize() | This allows Colorbox to be resized based on it‘s own auto-calculations, or to a specific size. This must be called manually after Colorbox‘s content has loaded. The optional parameters object can accept width or innerWidth and height or innerHeight. Without specifying a width or height, Colorbox will attempt to recalculate the height of it‘s current content. |
| $.colorbox.remove() | Removes all traces of Colorbox from the document. Not the same as $.colorbox.close(), which tucks colorbox away for future use. |
Event Hooks
These event hooks fire at the same time as their corresponding callbacks (ie. cbox_complete & onComplete), but can be used to make a universal change to Colorbox, while callbacks are only applied to selected elements.
// Example of using an event listener and public method to build a primitive slideshow:
$(document).bind(‘cbox_complete‘, function(){
setTimeout($.colorbox.next, 1500);
});
| cbox_open | triggers when Colorbox is first opened, but after a few key variable assignments take place. |
| cbox_load | triggers at the start of the phase where content type is determined and loaded. |
| cbox_complete | triggers when the transition has completed and the newly loaded content has been revealed. |
| cbox_cleanup | triggers as the close method begins. |
| cbox_closed | triggers as the close method ends. |

Follow me on Twitter and Github, that‘s where I‘m most active these days. I welcome email (), but I‘m afraid I no longer have time to answer personal requests for help regarding my plugins or posts. Thanks!
介绍
colorbox()函数使用一堆key/value对象和一个可选的callback函数
格式：$(‘selector‘).colorbox({key:value}, callback);
例子： $(‘a.gallery‘).colorbox({transition:‘fade‘, speed:500});
还是例子：$(‘button‘).colorbox({href:"thankyou.html"});
设置的值 |

| rel | false | Example:$(‘#example a‘).colorbox({rel:‘group1‘}) 这个可以根据元素的rel属性设置要显示的元素集合，也可以覆盖一个存在的rel属性 |
| width | false | Example: "100%", "500px", or 500 设置宽度，包括边框和按钮 |
| height | false | Example: "100%", "500px", or 500 设置高度，包括边框和按钮 |
| innerWidth | false | Example: "50%", "500px", or 500 这个可以设定一个固定的内大小，包括边框和按钮 |
