从等式中显示最小数字

Question

我需要显示是否answer =＆gt; 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);  
    }

如果＆lt; 2.80然后显示2.80

Answer 1

var var1 = 10;
var var2 = 5;
var minimum = Math.min( var1, var2 );
var maximum = Math.max( var1, var2 );
// minimum now equals 5;
// maximum now equals 10;

A reference on the Math object

Answer 2

Ue的功能不是直接向innerHTML添加输出。

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;
