<span id="ww1" class="glyphicon glyphicon-warning-sign form-control-feedback" style="display:none"></span>

<span id="ee1" class="glyphicon glyphicon-remove form-control-feedback" style="display:none"></span>
</div>
<div class="form-group has-feedback"
id="form2">
学号：<input type="text" id="input2" placeholder="请输入学号" >
<span style="display:none">你输入的信息是正确的</span>
<span class="glyphicon glyphicon-ok form-control-feedback" style="display:none"></span>
<span style="display:none">请输入正确信息</span>
<span class="glyphicon glyphicon-warning-sign form-control-feedback" style="display:none"></span>
<span style="display:none">验证不通过</span>
<span class="glyphicon glyphicon-remove form-control-feedback" style="display:none"></span>
</div>
<button type="submit" class="btn btn-primary" id="submit">提交</button>
</form>
<script src="http://cdn.bootcss.com/jquery/1.11.2/jquery.min.js"></script>
<script src="js/bootstrap.min.js"></script>
<script>
$("#submit").click(function(){
if($("#input1").val()==null)
{
$("#form1").addClase("has-warning");
$("#w1").show();
$("#ww1").show();
}
});
</script>
</body>
</html>
这样子写实现不了，<script></script>里是不是有问题

你把null和“”都去掉。换成if(!$("#input1").val()){ ...
}
他会把你判断的无值，未定义等判为false
