js - shorten the conditional statement

Is there a way to make the conditional statement below shorter? There is a lot of repetition as you can see:

var searchArea = function() {
    // Search the area around the current position for hidden doors
    if(detectWall('left') == 2) {
        status.innerHTML = "Hidden Door to the left";
    } else if (detectWall('right') == 2) {
        status.innerHTML = "Hidden door to the right";
    } else if (detectWall('up') == 2) {
        status.innerHTML = "Hidden door above you";
    } else if (detectWall('down') == 2) {
        status.innerHTML = "Hidden door below you";
    } else if (detectWall('right') == 3 || detectWall('left') == 3 || detectWall('up') == 3 || detectWall('down') == 3) {
        status.innerHTML = "You are close to the fountain";
    }


}

And detectWall function for reference:

 var detectWall = function(dir) {
    // Detect walls from the array
    switch(dir) {
        case 'right':
            return mapArray[parseInt(player.y/20)][parseInt((player.x+20)/20)]
        case 'left':
            return mapArray[parseInt(player.y/20)][parseInt((player.x-20)/20)]
        case 'up':
            return mapArray[parseInt((player.y-20)/20)][parseInt(player.x/20)]
        case 'down':
            return mapArray[parseInt((player.y+20)/20)][parseInt(player.x/20)]
        default:
            return false
    }

}

Thank you
