javascript - onchange 不工作

Question

我的站点中有以前的代码，在单个输入框加载中使用不同的值。我在代码中有四种贷款类型

1. Conv.  2.FHA  3.VA   4.USDA   if click any loan change value  

首付输入框value值

<td>Down payment $</td>
     <td> <input name="downpaymentpc" id="downpaymentpc" type="text" size="8" maxlength="8" onChange="javascript:downPaymentPcChanged(true);" value="<?php echo $min_fha_down_payment;?>" />%</td>

现在我有单独的所有贷款类型有四个下载付款输入框？我已经分配了四个输入框的值不工作显示默认值 3.5..如何设置不同的输入框相同的值我在旧网站上使用过

我的javascript代码:

 <script type="text/javascript">
    var min_jumbo_down_payment_1="<?php echo $min_jumbo_down_payment_1?>";
    var min_jumbo_down_payment_2="<?php echo $min_jumbo_down_payment_2?>";
    var min_fha_down_payment="<?php echo $min_fha_down_payment?>";
    var max_fha_loan="<?php echo $max_fha_loan?>";
    var max_va_loan="<?php echo $max_va_loan?>";

代码相同但功能不工作新的？有什么想法吗？

onchange 仅在控件模糊时触发。尝试使用 onkeypress 代替
