用onchange调用多个函数

这一切都有点超出我的经验，但我已经到处寻找可能，并且迄今为止研究了这些东西6个小时，并且只是碰到了砖墙。用onchange调用多个函数

我有一个表，用户输入两个变量，并从这两个变量12个不同的数字吐出来。 这些数字被作为纯文本字符串吐出到只读文本字段中，我需要将它们显示为（US）货币。 表中的所有输入字段都使用onchange来运行执行计算的第一个函数，但是我在网上找到的第二个和第三个函数无法运行。

HTML：

回答：

你的函数有一个不确定的变量amount。据推测他们只是因为错误而崩溃。

首先，您需要从onChange侦听器中删除这些函数调用。

其次，转变​​职能采取一个未格式化的值，并返回一个格式化的一个

function CurrencyFormatted(amount) { //<-- notice the method parameter 
    var i = parseFloat(amount); 
    if(isNaN(i)) { i = 0.00; } 
    var minus = ''; 
    if(i < 0) { minus = '-'; } 
    i = Math.abs(i); 
    i = parseInt((i + .005) * 100); 
    i = i/100; 
    s = new String(i); 
    if(s.indexOf('.') < 0) { s += '.00'; } 
    if(s.indexOf('.') == (s.length - 2)) { s += '0'; } 
    s = minus + s; 
    return s; 
}

现在改变每个组调用你updatesum先格式化值

var sum14 = ((((((document.form.sum1.value -0)*(document.form.sum2.value -0)*300))/12)/2)*.08); 
var formattedSum14 = CommaFormatted(CurrencyFormatted(sum14)); 
document.form.sum14.value = sum14;
