如何使用相同的算法或更好的方法将此PHP函数转换为JavaScript？

我在Facebook上回复了一个更新的jsFiddle，但我想我会在这里发布，以防万一。这是一个jsFiddle设置，结合if语句中缺少大括号，并将金额设置为整数而不是字符串。

function CalculateOrder(form)
{   
    //sample lang to sir ng javascript pero ito mismo na yung code.
    //naka comment sa html ung code sa php 
    if(form.text008.value == "1br")
    {
        form.amount.value ="119.00";
    }

    if(form.text008.value == "1br" && form.extrass.checked ==true)
    {
        form.amount.value = "139";
    }
}
