keep focus on text input field if another input field is not clicked

Question

I am trying to create an onblur event where any time some one clicks anywhere on the page it will stay focused on that element unless it is a specif element then it will refocus to that specific element. I am probably way off but this is what I tried, and it just stays focused on the Barcode element no matter what.

function stayOnBarcode() {
    var QTY = document.getElementById("QTY");
    var Barcode = document.getElementById("Barcode");
    if (Barcode.value === "") {
        if (QTY.focus() === true) {
            QTY.focus();
        }
        else if (document.hasFocus() === true) {
            Barcode.focus();
        }
    }
    else {
        Barcode.focus();
    }
}

How about something like this:

$(document).on("mousedown", function(e) {
    clicked = $(e.target)
})

$("input").on("blur", function() {
    if (!clicked.is("#QTY") && !clicked.is("#Barcode")) {
        $(this).focus()
    }
})

It stores the most recently clicked element in the variable clicked , then on blur event it checks if last_clicked is something other than #QTY or #Barcode . If so, it re-focuses the input being blurred.

You might need to tweak it to fit the exact conditions you have in mind, or feel free to add specifics to your question.
