onchange不能正常工作

我在我的站點中有以前的代碼在單個輸入框中使用不同的值加載。我在代碼onchange不能正常工作

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

首付輸入框的值值

<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>

現在我有另一四種貸款類型的所有貸款類型有四種下載支付輸入框？我有賦值四個輸入框中不能正常工作顯示默認值3.5..how設置不同的輸入框中輸入相同的值，我用我的舊網站

我的javascript代碼：

<script type="text/javascript">

下面的代碼工作正常網站網址： url

我開發的網站網址： my url

代碼是相同的，但功能不工作新的？有關它的任何想法？

您必須設置該元素的名稱和ID！ – Samane

根據Samane的說法，當你訪問像這樣的元素 'downpaymentamt = document.forms ['frmCalculator']。elements ['downpaymentamt'] value;' 文本'downpayment'實際上是指'name'的元素，而不是id。由於元素'」名稱爲「downpaymentpc」，而不是「downpayment」，嘗試獲取值失敗。你的調試器會告訴你，熟悉它。 – enhzflep

我已經爲每個輸入字段設置了每個名稱和我的名字？ @Samane –

onchange只在控件模糊時觸發。嘗試onkeypress而不是
