Javascript 将参数传递给函数

Question

嘿，我似乎无法让它工作，我对如何传递颜色参数有点困惑:

function colourGreen(red, green, blue)
        {
            document.getElementById("button1").style.backgroundColor = 'rgb(red,green,blue)';
        }

............ …………

<input type="button" id = "button2" value="Price up" onclick = 'colourGreen(0,255,0)'>

Answer 1

我猜这应该可以解决问题

function colourGreen(red, green, blue)
        {
            document.getElementById("button1").style.backgroundColor = 'rgb('+red+','+green+','+blue')';
        }
