Question

可以删除部分代码：

<input type="hidden" id="alt_date" name="selArrivalDate" value='<?php $datetime = new DateTime('tomorrow'); echo $datetime->format('Ymd'); ?>' />

提交按钮#bookingSubmitBtn2？

此处的表格：

$(document).ready(function() {      
    $("#bookingSubmitBtn").click(function() {
        if ($("#children").val() == "") {
            $("#children").remove();
        }
        $("#bookingForm").submit();
    });
});

<form name="buchenForm" id="bookingForm" method="get" action="searchresult1.php">
    <div>
        <input type="text" id="datepicker" value='<?php $datetime = new DateTime('tomorrow'); echo $datetime->format('d/m/Y'); ?>' class="form-control" />
        <input type="hidden" id="alt_date" name="selArrivalDate" value='<?php $datetime = new DateTime('tomorrow'); echo $datetime->format('Ymd'); ?>' />
    </div>
    <div class="form-group">
        <button type="submit" id="bookingSubmitBtn1" formaction="searchresult1.php">Search 1</button>
    </div>
    <div class="form-group">
        <button type="submit" id="bookingSubmitBtn2" formaction="searchresult2.php">Search 2</button>
    </div>
</form>
