Using JavaScript from External URL

---

Loading external JS libraries

For example, a custom Demo Spinner.

/* perform any action on widgets/variables within this block */

Page.onReady = function () {
    // For Setting values for External Spinner
    var opts = {
        lines: 15,
        length: 28,
        width: 14,
        radius: 42,
        scale: 1,
        corners: 1,
        color: '#000',
        opacity: 0.25,
        rotate: 0,
        direction: 1,
        speed: 1,
        trail: 60,
        fps: 20,
        zIndex: 2e9,
        className: 'spinner',
        top: '50%',
        left: '50%',
        shadow: false,
        hwaccel: false,
        position: 'absolute'
    };

    var target = document.getElementById('Demo');
    var spinner = new Spinner(opts).spin(target);
};
