Quick Fix: Scrolling and Focus when multiple bootstrap modals are open

When more than one modal is opened you might have noticed that after the latter modal loses its focus, the former modal loses its scrolling option, rather page’s body scrolls (if exists, otherwise no scrollbar!). There is a quick fix for this:

Using query string in script tag

It is possible to send query string to an external JavaScript file like this:

< script src="scripts.js?version=123"></script>

Get query string value

Get the value of a field from query string using JavaScript:

function getURLParameter(name) {
    return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)
                              (&|#|;|$)').exec(location.search)||[,""])
                              [1].replace(/\+/g, '%20'))||null
}
