Javascript 在表单中收集单独的值并将其作为一个字符串过帐

我正在处理这个表格

<form onsubmit="return validate();" method="get" action="http://marriott.com/reservation/availabilitySearch.mi" name="fullRatesCalloutForm" target="_blank">
    <h3>Reservations</h3>
          <input type="hidden" value="false" name="clusterSell">

如果我理解您正试图正确执行的操作，您可以创建如下字符串：

 var datePieces = dateText.split('/');
var month = datePieces[0];
var day = datePieces[1];
var year = datePieces[2];
//define select option values for
//corresponding element
$('select#month').val(month);
$('select#day').val(day);
$('select#year').val(year); }});

return month + '/' + day + '/' + year;

您是在提交表单还是在ajax中执行此操作？我们需要您何时执行此操作的详细信息。另外，这是用PHP编写的，但没有PHP。我更改了问题以帮助更好地解释。ThanksIt看起来你的JS也应该更新了，但是看看表单，你有一个隐藏的输入datepicker和datepicker2，它们有你需要的完整日期。
