Forms 自举形式中的高度 <div class="form-group "> <label class="control-label col-sm-3 col-xs-3 col-md-3 col-lg-3" for="email">E-mail</label><?php echo @$_SESSION['ctform']['email_error'] ?> <div class="col-sm-7 col-xs-7 col-md-7 col-lg-7"> <input class="form-control" id="email" name="ct_email" type="text" value="<?php echo htmlspecialchars(@$_SESSION['ctform']['ct_email']) ?>"/> </div> </div>

我有一个引导的形式：

 <div class="form-group ">
  <label class="control-label col-sm-3 col-xs-3 col-md-3 col-lg-3" for="email">E-mail</label><?php echo @$_SESSION['ctform']['email_error'] ?>
  <div class="col-sm-7 col-xs-7 col-md-7 col-lg-7">
   <input class="form-control" id="email" name="ct_email" type="text" value="<?php echo htmlspecialchars(@$_SESSION['ctform']['ct_email']) ?>"/>
  </div>
 </div>

名称 />

 <div class="form-group ">
  <label class="control-label col-sm-3 col-xs-3 col-md-3 col-lg-3" for="email">E-mail</label><?php echo @$_SESSION['ctform']['email_error'] ?>
  <div class="col-sm-7 col-xs-7 col-md-7 col-lg-7">
   <input class="form-control" id="email" name="ct_email" type="text" value="<?php echo htmlspecialchars(@$_SESSION['ctform']['ct_email']) ?>"/>
  </div>
 </div>

我无法定义字段的高度，因此字段之间有大量200px的空间。你知道怎么解决这个问题吗？谢谢。

试着这样做：

 <div class="form-group ">
  <label class="control-label col-sm-3 col-xs-3 col-md-3 col-lg-3" for="email">E-mail</label><?php echo @$_SESSION['ctform']['email_error'] ?>
  <div class="col-sm-7 col-xs-7 col-md-7 col-lg-7">
   <input class="form-control" id="email" name="ct_email" type="text" value="<?php echo htmlspecialchars(@$_SESSION['ctform']['ct_email']) ?>"/>
  </div>
 </div>

var el = document.querySelector(".form-group");
el.style.width = "200px";
