jEditor (js-document-editor) is a package that can help you show a simple interface and work as a document creation tool, where the user can move and resize the elements how they want inside a page (similar to Word).
You can download it directly or cloning the repository and copying the dist folder to your project.
This package is hosted as a npm package and can be installed directly from official repository using:
npm i js-document-editor
To make changes to this project is recommended to run this package inside a docker container using:
docker run -it --rm -v $(pwd):/app node bash
You need to import the css and js files (and fontawesome css in case you want it), then create a div with class jEditor
<html>
<head>
<link href="css/jeditor.css" rel="stylesheet" />
<link href="fa/css/all.min.css" rel="stylesheet" />
<!--If you wish to use fontawesome-->
</head>
<body>
<div class="jEditor"></div>
<script src="js/jeditor.js"></script>
<script>
const jEditor = $.jEditor(options);

topMargin: 'Top margin',
leftMargin: 'Left margin',
return: 'Return',
paperChange: 'The paper has been set to :size',
saved: 'Changes saved',
hPosition: 'Horizontal position',
vPosition: 'Vertical position',
textAlign: 'Text align',

},
Extra functions are shown on top of settings and can do a series of actions, for example:
function defaultValues() {
_jeditor.setData(defaultData);
_jeditor.renderObjects();
}
function saveData() {
_jeditor.getOptions().events.saveData();
var data = _jeditor.getData();
alert(`Saved data: ${data.length} elements`);
}You need to set your functions before $.jEditor()
[
{action: 'defaultValues', content: '<span class="fa fa-magic"></span> Default View', class: 'btn', show: true},
{action: 'saveData', content: '<span class="fa fa-save"></span> Save', class: 'btn', show: true},
]
Paper sizes are defined by pixels (based on your dpi) default values are:
paperSizes: {
letter: {name: 'Letter', width: 1276, height: 1648},
a4: {name: 'A4', width: 1240, height: 1754},
a5: {name: 'A5', width: 1240, height: 874}
},
Settings are shown at the bottom of the panel, basic functions are:
- toggleRender: set objects as rendered (not draggable or resizable)
- changePaper: changes the page size to the next paperSize in the array (goes to first if last is active)
- zoomOut: decreases the zoom by the amount set on zoomIncrement
- zoomIn: increases the zoom by the amount set on zoomIncrement
- zoomReset: sets the zoom to fit the page fully visible (horizontally)
settings: [
{action: 'toggleRender', content: '<span class="fa fa-edit"></span>', class: 'btn', show: true},
{action: 'changePaper', content: '<span class="fa fa-file"></span>', class: 'btn', show: true},
{action: 'zoomOut', content: '<span class="fa fa-minus"></span>', class: 'btn', show: true},
{action: 'zoomIn', content: '<span class="fa fa-plus"></span>', class: 'btn', show: true},
{action: 'zoomReset', content: '<span class="fa fa-expand-arrows-alt"></span>', class: 'btn', show: true},
],
After executing var jEditor = $.jEditor() you can use that variable or the global variable _jeditor to access some of it functions:
- getOptions(): return the options set at runtime.
- setOptions(options): return a merge of the options.
- getData(): return the data (values) set at runtime.
- setData(options): sets objects data (need to run renderObjects() to show it on editor).
- renderObjects(): Executes the event renderObjects (creates elements based on data).
- setPaper(paperSize): Executes the event setPaper (sets page size).
- setBackround(url): sets the background-image property of the page and as the background option (event setPageBackground()).
- clearBackround(): clears the page background and sets the option as null.
-
unsaved(): sets a
beforeunloadas en event listener. (event unsaved()). - getObject(element): returns the object inside the editor data with the index of the element sent as parameter.
You can run the editor functions anytime you need it, to access any function just use _jeditor.getOptions().events.xxxx() the events available are:
All functions takes the first parameter as a click event where it gets the targeted DOM element with the attribute [data-element=n]
- addElement(event): gets targeted element and adds the object to the page.
- removeElement(event): gets targeted element and removes the object from the page.
- modifyElement(event): gets targeted element and shows settings panel for the element.
- cancelModifyElement(event): hides the settings panel to show the element list.
- zoomIn(): increases the zoom by the amount set on zoomIncrement.
- zoomOut(): decreases the zoom by the amount set on zoomIncrement.
- zoomReset(): sets the zoom to fit the page fully visible (horizontally).
- changePaper(): changes the page size to the next paperSize in the array (goes to first if last is active).
- setPaper(event, paperSize): sets the page size to the paperSize value (has to exists in paperSizes).
- renderObjects(): renders the objects based on the data.
- toast(text, css, timer): shows a toast with the css as class (example "bg-success") for the timer amount (ms).
-
unsaved(): sets a
beforeunloadas en event listener. -
saveData(): removes
beforeunloadevent listener and shows a toast. - setPageBackround(url): sets the background-image property of the page and as the background option.
Elements are shown in the side panel and when clicked are added to the page as an object, can be defined with this options:
| option | default | description |
|---|---|---|
| align | String: "initial" | CSS value for text-align |

| height | Integer: 20 | height of the displayed object in pixels |

| width | Integer: 100 | width of the displayed object in pixels |
Data can be return with _jeditor.getData() or set with _jeditor.setData(...) (and run renderObjects() to show them), this values can have this options:
| option | default | description |
|---|---|---|
| element | Integer: null | index of item in element array |
| fontSize | Integer: 16 | font size in pixels |
| width | Integer: 100 | width of the displayed object in pixels |
