Draggable & Maximizable Dialog Window In Pure JavaScript – WindowJS


WindowJS is a standalone JavaScript library to create responsive, fully customizable dialog windows with resize/move/maximize/minimize capabilities.

How to use it:

Load the minified version of the WindowJS’ files in the HTML page.

<link rel="stylesheet" href="window.css">
<script src="window.js"></script>

Create a new dialog window instance.

const win = new Window("Dialog Title", {
      // options here

Insert content to the dialog window.

win.content.innerHTML = '<p>Dialog Window Here</p>';

Assign a unique ID to the dialog content.

win.content.id = "myContent";

Apply custom styles to the dialog window.

win.content.style.styleName = "value";

Possible options to customize the dialog window.
