There are at least a couple of ways to do this.

  1. Use document.createElement, which is one of the DOM API functions.

    // Create the element
var d = document.createElement('div');

// Set its ID
d.id = "popUpWin";

// Set the style properties on the element's `style` object
d.style.width = width + "px";

    d.style.height = height + "px";

    ...and then presumably put it somewhere in the document using appendChild or insertBefore or similar on another element already in the document.

  2. Use insertAdjacentHTML on an existing element:

    theOtherElement.insertAdjacentHTML(
    'beforeend',
    '<div id = "popUpWin" style = "width:' + width + 'px; height:' + height + 'px;"></div>'
);

    That example would add the div as a child right at the end of the existing element (without disturbing other elements already in it).

  3. Use innerHTML on an existing element, if you want to replace its content:

    theOtherElement.innerHTML =
    '<div id = "popUpWin" style = "width:' + width + 'px; height:' + height + 'px;"></div>';

    Note that that will remove any other elements inside theOtherElement and replace them with just that div.
