Question

我有一个文本字段，其中数字长度介于5到7个字符之间。并且选项卡处于活动状态，而其他两个则没有。我正在尝试根据文本字段的长度激活不同的选项卡。

<div class="form-group">

    <label class="col-md-offset-9 col-xs-1 control-label" for="NoDD">No:</label>  
    <div class="col-xs-2">
        <input id="NoDD" name="NoDD" placeholder="droit d'accÃ¨s" class="form-control input-md" required="" type="text">          
    </div>
    <label class='col-md-1' for='radio'>Prix</label>

    <ul class='nav nav-pills'>
        <li class="active"><a data-toggle='pill' href='#annuel'>Annuel</a></li>
        <li><a data-toggle='pill' href='#journalier'>Journalier</a></li>
        <li><a data-toggle='pill' href='#location'>Location</a></li>
    </ul>

    <div class='tab-content'>
        <div id='annuel' class='tab-pane fade in active'>

            <div class='col-md-offset-1 col-md-3'>
                <label class='radio-inline' for='radio-0'>Jusqu'au 9 déc. 2014 <br>
                    <input name='radio' id='radio-0' type='radio' value="300">300$
                </label>
            </div>
            <div class='col-md-3'>
                <label class='radio-inline' for='radio-1'>Après le 9 déc. 2014 <br>
                    <input name='radio' id='radio-1' type='radio' value="360">360$
                </label>

也许是这样的？

$("#NoDD").on("input", function() {
  var quantity = $(this).val().length;
  if (quantity == 5) {
   // do something
  } else if (quantity == 6) {
   // do something
  } else if (quantity == 7) {
   // do something
  }
});

我想使用jquery基于另一个字段的长度激活选项卡
