Javascript 如何使用单输入框两个值？

在我前面的代码中，我有两个单独的输入框%和$value，如下所示：

<tr>
    <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>
    <td colspan="2">Or $
        <input name="downpaymentamt" id="downpaymentamt" type="text" size="8" maxlength="8" onChange="javascript:downPaymentAmountChanged(true);" />
    </td>
</tr>

我的代码有错误吗

HTML:

<img src="Content/Images/percent.png" type="per" class="changeImg" style="cursor:pointer"/>

$(document).ready(function () {
    $(".changeImg").click(function () {
        var type = $(this).attr("type");
        if (type == 'per') {
            $(this).attr({
                "type": "amount",
                "src": "Content/Images/dollar.png"
            });
            $("#downpaymentpc").attr("onchange", "downPaymentAmountChanged(true);");

        } else if (type == 'amount') {
            $(this).attr({
                "type": "per",
                "src": "Content/Images/percent.png"
            });
            $("#downpaymentpc").attr("onchange", "downPaymentPcChanged(true);");
        }
    });
});
