Question

I need to show if answer = >2.80

  var panel; 
    if (routeNodes.length > 0 && (panel = document.getElementById('distance')))    
    {               
        panel.innerHTML = Number((dist/1609.344).toFixed(1)).toFixed(2)
                        + " miles = £" 
                        + Number((((dist/1609.344 - 1) * 1.20) + 2.80).toFixed(1)).toFixed(2);  
    }

if < 2.80 then show 2.80

Answer 1

Ue functions instead of directly adding output to innerHTML.

function getDistance(input, minimum) {
    var miles = f(input);
    return Math.max(miles, minimum);
}

var string = getDistance(someValue, 2.80) + ' miles -- ' + getDistance(someValue, 2.80)
panel.innerHTML = string;
