  } else if ($(this).val()== 'B') {
     $('#text1').val('8');
       $('#text2').val("<?php echo date('m/d/Y', strtotime($myDate . ' +8 Weekdays')); ?>");

<div class="col-xs-3">
   <label class="control-label">Option</label>

ID为Text1和Text2。尝试如下：

<script>
$('#Option1').change(function(){
    if ($(this).val()== 'A') {
        $('#Text1').val('3');
        $('#Text2').val("<?php echo date('m/d/Y', strtotime($myDate . ' +1 Weekdays')); ?>");
    } else if ($(this).val()== 'B') {
         $('#Text1').val('8');
         $('#Text2').val("<?php echo date('m/d/Y', strtotime($myDate . ' +8 Weekdays')); ?>");
        }
    });
 </script>

它很管用！注意正确的id：您应该插入

$('#Text1').val('3');

而不是

$('#text1').val('3');
