popups

HTML Quick Popup dialog library

Usage

import {popups,Popup} from "popups.mjs";

var popup = popups.create( "caption" );

// show a dialog
popup.show();

// hide a ialog
popup.hide();

// set a new caption
popup.caption = "New Caption";

// this is the content of the frame (inner content div)
popup.divContent  // insert frame content here

// this is the frame of the frame (outer div)
popup.divFrame // insert frame content here


popup.appendChild( createElement( "canvas" ) ); // add something to draw into on the form.

Generally popups work like VERY simple GUI widgets... some of the popups.makeButton sort of methods return just a simple html element.

Utility interface

The popups object that is exports is a namespace that contains functions that are generally useful for working with forms; there are canned sort of common higher level controls that have a label and a value associated with them; or quick stylable button.

|popups methods| arguments/type | description | |----|---|---| | defaultDrag | true | option toggle whether to enable mouse dragging on frames | | autoRaise | true | option to toggle whether clicks on frames auto raise them to top | | create | (caption [, parent]) | create a new blank popup with specified caption ; if caption is an empty string, no title caption is shown. | | simpleForm | (title, question, defaultValue, ok, cancelCb ) | create a simple yesno form with a title, and a string question; and a text input field for user input | | simpleNotice | ( title, question, ok, cancel ) | Create just a popup notice with Ok, and optional Cancel button. | | list | (parentList,toString) | Creates a list with a specified tostring method for elements. | | makeCheckbox | (form, o, text, field ) | make a checkmark button, which is bound to object 'o' and member 'field'. The title is shown next to the checkbox. | | makeNameInput | (form, o, text, field ) | make a static text display, with a button to click to edit the text | | makeTextInput |(form,o,field,text, money, percent) | make a text input with a lable next to it | | makeTextField |(form,o,field,text, money, percent) | make a text display with a label next to it (like input but readonly) | | makeButton | (parentElement,text, callback) | adds a button; is 2 divs nested and styled. Callback is called when the button is clicked/touched. | | setClass| (element.class) | Set a class in className | | toggleClass| (element,class) | if a class is in a class, remove it, else add it | | clearClass| (element,class) | remove a class from className | | createMenu | () | returns a menu object which is a popup menu | | | | | | DataGrid | (parent, o, field, options) | Create a data grid view for the specified array; binds controls directly to the array; cancel will reset the content. | | PagedFrame | (parent, options ) | Create a paged form (pages get added with a tab that when the tab is selected the content in the frame is shown. | | | | | | Alert | (string) | Show a generic singleton alert banner; hide() is available, if multiple show(newString) happen, the banner remains up, and just updates the text content | | AlertForm | () | This is the form used by Alert, it extends Popup(), and just has simple single-touch/any click to clear. | | Popup | (...) | Same as the exported Popup symbol |

Popup class

This popup class is a standard high level contain that is the general abstraction for forms.

|Method| arguments | return | description | |-----|-----|-----|-----| |(contructor)| (title,parent,opts) | A new Popup object | Parameters to the constructor are optional. The first parameter may be a string which is the default name to show on the title bar of the Popup frame. The second parameter is a HTML Element or Popup to use as a parent (uses .appendChild( divFrame ) to add itself ot the parent. The third option parmeter is described below. | |show | () | undefined | shows a hidden popup in its current position | | center | () | undefined | A popup needs to be attached to a page, and visible (have a layout applied), then this can calculate where to position the form to center it on the visible page.| |hide | () | undefined | hides a popup. (sets display:none on the top level control) | | caption | -setter- | undefined | set the current text of the popup caption. (The text of popup.divTitle)| | over | (element) | undefined | positions the frame aligned to the top left of the specified HTML element element | | on | (event,cb) | undefined | register a handler for events on the popup. Events are described later. | | reset | () | undefined | issue reset event on popup | | reject | () | undefined | issue reject event on popup | | accept | () | undefined | issue accept event on popup | | move | (x,y) | undefined | uses the specified x and y floating point numbers as percentages to set top and left to. | | appendChild | (element) | this.appendChild's result| Ads a HTML element to this form's content area | | remove | () | undefined | remove all elements from the page. |

Popup Constructor Options

|Name| type| default | Description | |----|----|----| |suffix| string | "" | Specifies a suffix to apply to elements created in this form. The popups utility methods use this when created on a Popup form instead of just an HTML element. | |enableClose | boolean | false | Enables showing a close button in the title bar frame. Clicking the button automatically hide()s the popup an dissues a close event. | | from | HTML Element | null | if from is specified, then the specified element is used for the popup divFrame, and all other div* elements are set to null. |

Popup Registered Events

The event function on() can be used to define user events, which are generated for the user by the user.

Passing on(event name, function) registers an additional function handler for the event. Functions are executed in the order they were added to handle the event.

Using on( event name, non-function) will call the event handler associated with the specified event name, and pass the argument supplied as data to the registered callback.

These are only loosely implemented...

|Event Name| Data | Description | |----|----|----| |reset |true | when the popup's reset method is run, which resets any changes to current values to their initialValue (more later). | |accept | true | Issued when the changes in a form are meant to be saved to real states; (save changes) | |cancel | true | Issued when changes should be ignored; and the form is closed; | |show| true | Issued when a popup has been told to show itself; Forms that extend Popup should just override the show() method... | |close | true | some forms generate a close event. |

Object members

A Popup instance exposes these data members to be able to work with internals of the popup.

|name | type | description | |----|-----|-----| |divFrame | HTML Element | This is the control the popup uses as the overall container for all internal elements.| |divCaption | HTML Element | This is the frame of the caption area on the dialog; may be used to contain other button-type elements. | |divTitle | HTML Element | This is the text span of the title text in the caption. | |divContent | HTML Element | This is the element that contains all of the form's content. The Popup method appendChild() appends children to this element. | |divClose | HTML Element | This is the close button in the caption area container. | |useMouse | boolean | Can be used to disable mouse drag move on the popup. |

Popup Example

class MyForm extends Popup {
	constructor(parent) {
		super( "My Form Name", parent );
	}
}

// create a new MyForm parented to the document's body element...
const form = new MyForm( document.body );

Lists

Drag and drop nested items in lists. This is a list container, allows adding items.

The list items may have click callback events.

The list provides callbacks for item call events? Also for adding/removing items by drag and drop operations?

Data Grid View

This shows a data grid (table) with column headers; it shows a list of records in an array. It may be able to add/remove elements from the array it has been passed; this complicates the accept/reject option.

Menu

This handles a rectangular popup menu (drop list) of items. When it shows the dialog, it puts an invisible cover-all div on the page such that any mouse event outside of the popup is captured by the popup; making these modal.

Often this sort of menu is triggered by a user right-clicking or control-clicking on a surface, and if another root menu is shown, others should already have gone away.

const menu = popups.createMenu();
menu.addItem( "text", ()=>{
	/* called when item is selected */
} );

menu.separate();

const subMenu = menu.addMenu( "Menu Entry Text" );

Data Grid

new DataGrid( parent, object, field, opts );
