单个输入字段使用四个位置
Single input fields using to four place
在我以前的代码有四个贷款类型。四个贷款类型值加载单个输入字段。这是我原来的UI。
<td width="20%">Type of Loan: </td>
<td width="30%" >
<input type="radio" value="jumbo" name="loantype" onClick="javascript:loanTypeChanged()"/> Conforming/Jumbo<br />
<input type="radio" value="fha" name="loantype" checked onClick="javascript:loanTypeChanged()"/> FHA<br />
<input type="radio" value="va" name="loantype" onClick="javascript:loanTypeChanged()" /> VA<br />
<input type="radio" value="usda" name="loantype" onClick="javascript:loanTypeChanged()" /> USDA<br />
</td>
说明代码为四种贷款类型的代码。所有贷款类型加载值单个输入字段
前期MIP
现在我新的Ui设计四个贷款类型有每个输入字段如何使用这个输入字段四个贷款每个类型?
这是我的脚本:
function isNumeric(strString)
// check for valid numeric strings
{
var strValidChars = "0123456789.-";
var strChar;
var blnResult = true;
if (strString.length == 0) return false;
// test strString consists of valid characters listed above
for (i = 0; i < strString.length && blnResult == true; i++)
{
strChar = strString.charAt(i);
if (strValidChars.indexOf(strChar) == -1)
{
blnResult = false;
}
}
return blnResult;
}
function ficoChanged()
{
//setDownPayment();
getMIP("hh");
}
function loanTypeChanged()
{
setDownPayment();
getMIP("loantype"); //it must be set to loantype

please Help me ?我累了复制输入粘贴四个位置它显示相同的值四个位置?
你可以利用jQuery来缩减你的代码，使它更简洁。
$('input[name=loantype]').on('change', function() {
var loanAmount = +$(this).closest('tr').prev().find('input[name=' + this.value + ']').val();
console.log( this.value, loanAmount );
//other code
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
