/**
 * inputfields.js - JS specific to behavior of ProcessWire Inputfield forms. 
 * 
 * REQUIREMENTS
 * ============
 *  - ProcessWire or a module that uses its Inputfield Forms
 *  - One or more form.InputfieldForm elements
 *  - jQuery is used throughout 
 * 
 * PUBLIC API (3.0.144+)
 * ==========
 * Note: any 'f' below arguments may be an Inputfield $element, "#id" string, ".class" string or field name.
 * Many of the functions also support extra arguments such as a callback function, see Inputfields variable
 * definition for more details on arguments. For functions that show “…” as the arguments, see the full 
 * function definition for details. 
 * 
 * - Inputfields.open(f): Open the given Inputfield if not already open.
 * - Inputfields.close(f): Close the given Inputfield if not already closed. 
 * - Inputfields.toggle(f): Find and toggle the open/closed state of given Inputfield. 
 * - Inputfields.find(f): Find and highlight the given Inputfield (at any depth, in any tab). 
 * - Inputfields.focus(f): Find the given Inputfield and focus its input element (at any depth, in any tab).
 * - Inputfields.highlight(f): Temporarily highlight the given Inputfield with a background color. 
 * - Inputfields.reload(f): Force given Inputfield to reload via ajax (if supported).
 * - Inputfields.redraw(…): Redraw Inputfields after a visibility or width change. 
 * - Inputfields.inView(f): Is the Inputfield currently in the user’s viewable area?
 * - Inputfields.hidden(f): Does the given Inputfield currently have a hidden state?
 * - Inputfields.changed(f): Has given Inputfield changed? (or use 2nd argument to set)
 * - Inputfields.columnWidth(f): Get the column width percent of Inputfield (between 1-100) 
 * - Inputfields.columnWidth(f, w): Set the column width percent of Inputfield, where w is percent width between 1-100.
 * - Inputfields.name(f): Get the name of the given Inputfield
 * - Inputfields.label(f): Get the text label of the given Inputfield
 * - Inputfields.input(f): Get the input element(s) within the given Inputfield
 * - Inputfields.insertBefore(f, ff): Insert Inputfield 'f' before Inputfield 'ff'.
 * - Inputfields.insertAfter(f, ff): Insert Inputfield 'f' after Inputfield 'ff'.
 * - Inputfields.startSpinner(f): Start spinner for Inputfield.
 * - Inputfields.stopSpinner(f): Stop spinner for Inputfield. 
 * - Inputfields.init(target): Manually initialize all .Inputfield elements within target.
 *   Calling init() is only necessary for Inputfields not present during page load. 
 * - This file also contains lots of other functions, but they are not part of the public API. 
 * 
 * CLASSES
 * =======
 * Form classes:
 * - InputfieldForm: Class assigned to all Inputfield forms.
 * - InputfieldFormConfirm: Form that will warn the user if they attempt to navigate away before submit.
 * - InputfieldFormSubmitted: Class assigned to form when the submit button has been pressed. 
 * - InputfieldFormFocusFirst: Class assigned to form that should focus the first field. 
 * - InputfieldFormNoDependencies: Form with dependencies disabled.
 * - InputfieldFormNoWidths: Form with column widths disabled (or handled elsewhere).
 * - InputfieldFormNoHeights: Form where matching of column heights is disabled (or handled elsewhere).
 * - InputfieldFormNoFocus: Form where automatic focus of first field is specificallyl disabled. 
 * - nosubmit: Internal class assigned when submit of form is temporarily disabled due to other events.
 *     
 * Form field (Inputfield) classes:    
 * - Inputfield: Assigned to all Inputfield elements.
 * - Inputfield[Type]: Class where [Type] is replaced by Inputfield type, i.e. "Radios", "Select", etc.
 * - InputfieldWrapper: Assigned to Inputfields that can contain other Inputfield elements. 
 * - InputfieldStateHidden: Item that is current in a hidden state (not visible to user).
 * - InputfieldStateRequired: Item that requires a value in at least one of its inputs. 
 * - InputfieldStateChanged: Item that has changed. 
 * - InputfieldStateShowIf: Item that contains a show-if dependency via a 'data-show-if' attribute.
 * - InputfieldStateRequiredIf: Item that contains a required-if dependency via a 'data-required-if' attribute.
 * - InputfieldStateCollapsed: Item that is collapsed and must be clicked to be opened. 
 * - InputfieldStateWasCollapsed: Item that was previously collapsed. 
 * - InputfieldStateToggling: Item that is currently between an open and collapsed state. 
 * - InputfieldColumnWidth: Item that has some column width smaller than 100%. 
 * - InputfieldColumnWidthFirst: Item that has column width < 100% and is the first in a row of columns.
 * - InputfieldColumnWidthFirstTmp: Temporary/runtime class for column width used internally.
 * - InputfieldNoFocus: Item that should not have its input element automatically focused. 
 * - InputfieldAjaxLoading: Item that is currently loading from an ajax request. 
 * - InputfieldIgnoreChanges: Item that should not be tracked for changes to value.
 * - InputfieldHasUpload: Item that has a file upload input within it. 
 * - InputfieldIsOffset: Item that is offset from others (not supported by all admin themes). 
 * - InputfieldRepeaterItem: Item that represents a Repeater item. 
 * - collapsed9: Item that is not collapsible (always open). 
 * - collapsed10: Item that is collapsed and dynamically loaded by AJAX when opened.
 * - collapsed11: Item that is collapsed only when blank, and dynamically loaded by AJAX when opened.
 * 
 * Children of Inputfield elements have these classes:
 * - InputfieldHeader: Assigned to the header of an Inputfield, typically the <label> element. Always visible.
 * - InputfieldHeaderHidden: When paired with InputfieldHeader classs, indicate header is hidden.
 * - InputfieldStateToggle: Assigned to element that toggles open/collapsed state (typically InputfieldHeader). 
 * - InputfieldContent: Assigned to the content of the Inputfield, wraps any <input> elements. Hidden when collapsed.
 *     
 * Other classes:
 * - Inputfields: Class <ul> or other element that contains .Inputfield children. 
 * - body.InputfieldColumnWidthsInit: Class assigned to body element when column widths initialized. 
 * - i.toggle-icon: Assigned to icon that also works as an .InputfieldStateToggle element. 
 * - maxColHeightSpacer: Used internally for aligning the height of a row of columns, when applicable. 
 * 
 * EVENTS
 * ======
 * Dependency events:
 * - showInputfield: Inputfield is shown as a result of field dependencies, triggered on document element, receives $inputfield as argument.
 * - hideInputfield: Inputfield is hidden as a result of field dependencies, triggered on document element, receives $inputfield as argument.
 * 
 * Visibility events: 
 * - openReady: Called right before Inputfield is opened, triggered on .Inputfield element. 
 * - opened: Called after Inputfield is opened, triggered on .Inputfield element.
 * - closeReady: Called before Inputfield is closed/collapsed, triggered on .Inputfield element.
 * - closed: Called after Inputfield is closed/collapsed, triggered on .Inputfield element.
 * - reload: Can be triggered on an .Inputfield element to force it to reload via ajax (where supported). 
 * - reloaded: Triggered on an .Inputfield element after it has reloaded via ajax. 
 * - resized: Triggered on an .Inputfield element after something has caused it to resize. 
 * - columnWidth: Triggered on .Inputfield when an API call to set column width, receives width percent after event argument.
 * 
 * Other events:
 * - changed: Triggered on an .Inputfield that has an input element within it changed (3.0.184+)
 * - AjaxUploadDone: Triggered on an .Inputfield element after a file has been ajax-uploaded within it. 
 * 
 * ATTRIBUTES
 * ==========
 * Form attributes:
 * - data-colspacing: form elements may have a "data-colspacing" attribute with a 0 or 1 value that indicates space between Inputfield columns. 
 * - data-confirm: form.InputfieldFormConfirm elements have this attribute with an alert message to display when appropriate. 
 * - data-uploading: form elements may have this to indicate a message shown when an action can abort a file that is uploading.
 * 
 * Inputfield attributes:
 * - data-show-if: Contains the selector for a "show if" condition when Inputfield has InputfieldStateShowIf class.
 * - data-required-if: Contains the selector for a "required if" condition when Inputfield has InputfieldStateRequiredIf class.
 * - data-colwidth: Contains the specified column width for the field (percentage) if Inputfield has an InputfieldColumnWidth class.
 * - data-original-width: Used internally to remember the original value of data-colwidth when dependencies change the equation.
 * - id: The Inputfield elements can have an "id" attribute of "wrap_Inputfield_[name]" where [name] is the input name.
 *   This is only the case if a different "id" attribute has not been specifically assigned to it.
