Thank you for the update! Here is my version.

// jumpabove
function isblank(str) {
    return /^\s*$/.test(str);
}

var y = document.selection.GetActivePointY(eePosLogical);
if(y > 1) {
    if(!isblank(document.GetLine(y))) {  // skip nonblank lines
        while(y > 1 && !isblank(document.GetLine(y))) y--;
    }
    else if(!isblank(document.GetLine(y-1))) {  // skip nonblank lines
        y--;
        while(y > 1 && !isblank(document.GetLine(y))) y--;
    }
    else {  // go to start of this block of blanks
        while(y > 1 && isblank(document.GetLine(y))) y--;
        if(y > 1 || !isblank(document.GetLine(1))) y++;
    }
    document.selection.SetActivePoint(eePosLogical, 1, y, false);
}

// jumpbelow
function isblank(str) {
    return /^\s*$/.test(str);
}

var y = document.selection.GetActivePointY(eePosLogical);
var n = document.GetLines();
if(y < n) {
    if(!isblank(document.GetLine(y))) {  // skip nonblank lines
        while(y < n && !isblank(document.GetLine(y))) y++;
    }
    else if(!isblank(document.GetLine(y+1))) {  // skip nonblank lines
        y++;
        while(y < n && !isblank(document.GetLine(y))) y++;
    }
    else {  // go to end of this block of blanks
        while(y < n && isblank(document.GetLine(y))) y++;
        if(y < n || !isblank(document.GetLine(n))) y--;
    }
    document.selection.SetActivePoint(eePosLogical, 1, y, false);
}
