|---|
| | 24 | * Create an accessible, unobtrusive tab interface based on a particular HTML structure. |
|---|
| | 25 | * |
|---|
| | 26 | * The underlying HTML has to look like this: |
|---|
| | 27 | * |
|---|
| | 28 | * <div id="container"> |
|---|
| | 29 | * <ul> |
|---|
| | 30 | * <li><a href="#fragment-1">Section 1</a></li> |
|---|
| | 31 | * <li><a href="#fragment-2">Section 2</a></li> |
|---|
| | 32 | * <li><a href="#fragment-3">Section 3</a></li> |
|---|
| | 33 | * </ul> |
|---|
| | 34 | * <div id="fragment-1"> |
|---|
| | 35 | * |
|---|
| | 36 | * </div> |
|---|
| | 37 | * <div id="fragment-2"> |
|---|
| | 38 | * |
|---|
| | 39 | * </div> |
|---|
| | 40 | * <div id="fragment-3"> |
|---|
| | 41 | * |
|---|
| | 42 | * </div> |
|---|
| | 43 | * </div> |
|---|
| | 44 | * |
|---|
| | 45 | * Each anchor in the unordered list points directly to a section below represented by one of the |
|---|
| | 46 | * divs (the URI in the anchor's href attribute refers to the fragment with the corresponding id). |
|---|
| | 47 | * Because such HTML structure is fully functional on its own, e.g. without JavaScript, the tab |
|---|
| | 48 | * interface is accessible and unobtrusive. |
|---|
| | 49 | * |
|---|
| | 50 | * A tab is also bookmarkable via hash in the URL. Use the History/Remote plugin (Tabs will |
|---|
| | 51 | * auto-detect its presence) to fix the back (and forward) button. |
|---|
| | 52 | * |
|---|
| | 53 | * @example $('#container').tabs(); |
|---|
| | 54 | * @desc Create a basic tab interface. |
|---|
| | 55 | * @example $('#container').tabs(2); |
|---|
| | 56 | * @desc Create a basic tab interface with the second tab initially activated. |
|---|
| | 57 | * @example $('#container').tabs({disabled: [3, 4]}); |
|---|
| | 58 | * @desc Create a tab interface with the third and fourth tab being disabled. |
|---|
| | 59 | * @example $('#container').tabs({fxSlide: true}); |
|---|
| | 60 | * @desc Create a tab interface that uses slide down/up animations for showing/hiding tab |
|---|
| | 61 | * content upon tab switching. |
|---|
| | 62 | * |
|---|
| | 63 | * @param Number initial An integer specifying the position of the tab (no zero-based index) that |
|---|
| | 64 | * gets activated at first (on page load). Two alternative ways to specify |
|---|
| | 65 | * the active tab will overrule this argument. First a li element |
|---|
| | 66 | * (representing one single tab) belonging to the selected tab class, e.g. |
|---|
| | 67 | * set the selected tab class (default: "tabs-selected", see option |
|---|
| | 68 | * selectedClass) for one of the unordered li elements in the HTML source. |
|---|
| | 69 | * In addition if a fragment identifier/hash in the URL of the page refers |
|---|
| | 70 | * to the id of a tab container of a tab interface the corresponding tab will |
|---|
| | 71 | * be activated and both the initial argument as well as an eventually |
|---|
| | 72 | * declared class attribute will be overruled. Defaults to 1 if omitted. |
|---|
| | 73 | * @param Object settings An object literal containing key/value pairs to provide optional settings. |
|---|
| | 74 | * @option Array<Number> disabled An array containing the position of the tabs (no zero-based index) |
|---|
| | 75 | * that should be disabled on initialization. Default value: null. |
|---|
| | 76 | * A tab can also be disabled by simply adding the disabling class |
|---|
| | 77 | * (default: "tabs-disabled", see option disabledClass) to the li |
|---|
| | 78 | * element representing that particular tab. |
|---|
| | 79 | * @option Boolean bookmarkable Boolean flag indicating if support for bookmarking and history (via |
|---|
| | 80 | * changing hash in the URL of the browser) is enabled. Default value: |
|---|
| | 81 | * false, unless the History/Remote plugin is included. In that case the |
|---|
| | 82 | * default value becomes true. @see $.ajaxHistory.initialize |
|---|
| | 83 | * @option Boolean remote Boolean flag indicating that tab content has to be loaded remotely from |
|---|
| | 84 | * the url given in the href attribute of the tab menu anchor elements. |
|---|
| | 85 | * @option String spinner The content of this string is shown in a tab while remote content is loading. |
|---|
| | 86 | * Insert plain text as well as an img here. To turn off this notification |
|---|
| | 87 | * pass an empty string or null. Default: "Loading…". |
|---|
| | 88 | * @option String hashPrefix A String that is used for constructing the hash the link's href attribute |
|---|
| | 89 | * of a remote tab gets altered to, such as "#remote-1". |
|---|
| | 90 | * Default value: "remote-tab-". |
|---|
| | 91 | * @option Boolean fxFade Boolean flag indicating whether fade in/out animations are used for tab |
|---|
| | 92 | * switching. Can be combined with fxSlide. Will overrule fxShow/fxHide. |
|---|
| | 93 | * Default value: false. |
|---|
| | 94 | * @option Boolean fxSlide Boolean flag indicating whether slide down/up animations are used for tab |
|---|
| | 95 | * switching. Can be combined with fxFade. Will overrule fxShow/fxHide. |
|---|
| | 96 | * Default value: false. |
|---|
| | 97 | * @option String|Number fxSpeed A string representing one of the three predefined speeds ("slow", |
|---|
| | 98 | * "normal", or "fast") or the number of milliseconds (e.g. 1000) to |
|---|
| | 99 | * run an animation. Default value: "normal". |
|---|
| | 100 | * @option Object fxShow An object literal of the form jQuery's animate function expects for making |
|---|
| | 101 | * your own, custom animation to reveal a tab upon tab switch. Unlike fxFade |
|---|
| | 102 | * or fxSlide this animation is independent from an optional hide animation. |
|---|
| | 103 | * Default value: null. @see animate |
|---|
| | 104 | * @option Object fxHide An object literal of the form jQuery's animate function expects for making |
|---|
| | 105 | * your own, custom animation to hide a tab upon tab switch. Unlike fxFade |
|---|
| | 106 | * or fxSlide this animation is independent from an optional show animation. |
|---|
| | 107 | * Default value: null. @see animate |
|---|
| | 108 | * @option String|Number fxShowSpeed A string representing one of the three predefined speeds |
|---|
| | 109 | * ("slow", "normal", or "fast") or the number of milliseconds |
|---|
| | 110 | * (e.g. 1000) to run the animation specified in fxShow. |
|---|
| | 111 | * Default value: fxSpeed. |
|---|
| | 112 | * @option String|Number fxHideSpeed A string representing one of the three predefined speeds |
|---|
| | 113 | * ("slow", "normal", or "fast") or the number of milliseconds |
|---|
| | 114 | * (e.g. 1000) to run the animation specified in fxHide. |
|---|
| | 115 | * Default value: fxSpeed. |
|---|
| | 116 | * @option Boolean fxAutoHeight Boolean flag that if set to true causes all tab heights |
|---|
| | 117 | * to be constant (being the height of the tallest tab). |
|---|
| | 118 | * Default value: false. |
|---|
| | 119 | * @option Function onClick A function to be invoked upon tab switch, immediatly after a tab has |
|---|
| | 120 | * been clicked, e.g. before the other's tab content gets hidden. The |
|---|
| | 121 | * function gets passed three arguments: the first one is the clicked |
|---|
| | 122 | * tab (e.g. an anchor element), the second one is the DOM element |
|---|
| | 123 | * containing the content of the clicked tab (e.g. the div), the third |
|---|
| | 124 | * argument is the one of the tab that gets hidden. If this callback |
|---|
| | 125 | * returns false, the tab switch is canceled (use to disallow tab |
|---|
| | 126 | * switching for the reason of a failed form validation for example). |
|---|
| | 127 | * Default value: null. |
|---|
| | 128 | * @option Function onHide A function to be invoked upon tab switch, immediatly after one tab's |
|---|
| | 129 | * content got hidden (with or without an animation) and right before the |
|---|
| | 130 | * next tab is revealed. The function gets passed three arguments: the |
|---|
| | 131 | * first one is the clicked tab (e.g. an anchor element), the second one |
|---|
| | 132 | * is the DOM element containing the content of the clicked tab, (e.g. the |
|---|
| | 133 | * div), the third argument is the one of the tab that gets hidden. |
|---|
| | 134 | * Default value: null. |
|---|
| | 135 | * @option Function onShow A function to be invoked upon tab switch. This function is invoked |
|---|
| | 136 | * after the new tab has been revealed, e.g. after the switch is completed. |
|---|
| | 137 | * The function gets passed three arguments: the first one is the clicked |
|---|
| | 138 | * tab (e.g. an anchor element), the second one is the DOM element |
|---|
| | 139 | * containing the content of the clicked tab, (e.g. the div), the third |
|---|
| | 140 | * argument is the one of the tab that gets hidden. Default value: null. |
|---|
| | 141 | * @option String navClass A CSS class that is used to identify the tabs unordered list by class if |
|---|
| | 142 | * the required HTML structure differs from the default one. |
|---|
| | 143 | * Default value: "tabs-nav". |
|---|
| | 144 | * @option String selectedClass The CSS class attached to the li element representing the |
|---|
| | 145 | * currently selected (active) tab. Default value: "tabs-selected". |
|---|
| | 146 | * @option String disabledClass The CSS class attached to the li element representing a disabled |
|---|
| | 147 | * tab. Default value: "tabs-disabled". |
|---|
| | 148 | * @option String containerClass A CSS class that is used to identify tab containers by class if |
|---|
| | 149 | * the required HTML structure differs from the default one. |
|---|
| | 150 | * Default value: "tabs-container". |
|---|
| | 151 | * @option String hideClass The CSS class used for hiding inactive tabs. A class is used instead |
|---|
| | 152 | * of "display: none" in the style attribute to maintain control over |
|---|
| | 153 | * visibility in other media types than screen, most notably print. |
|---|
| | 154 | * Default value: "tabs-hide". |
|---|
| | 155 | * @option String loadingClass The CSS class used for indicating that an Ajax tab is currently |
|---|
| | 156 | * loading, for example by showing a spinner. |
|---|
| | 157 | * Default value: "tabs-loading". |
|---|
| | 158 | * @option String tabStruct @deprecated A CSS selector or basic XPath expression reflecting a |
|---|
| | 159 | * nested HTML structure that is different from the default single div |
|---|
| | 160 | * structure (one div with an id inside the overall container holds one |
|---|
| | 161 | * tab's content). If for instance an additional div is required to wrap |
|---|
| | 162 | * up the several tab containers such a structure is expressed by "div>div". |
|---|
| | 163 | * Default value: "div". |
