How layui determines password inconsistency

<div class="layui-form-item">
  <div class="layui-inline">
	<label class="layui-form-label">登录密码</label>
	<div class="layui-input-inline">
	  <input type="password" name="password"  lay-verify="required" class="layui-input">
	</div>
  </div>
  <div class="layui-inline">
	<label class="layui-form-label">确认密码</label>
	<div class="layui-input-inline">
	  <input type="password" lay-verify="required|confirmPass" class="layui-input">
	</div>
  </div>
</div>

// 校验两次密码是否一致
form.verify({
    confirmPass:function(value){
        if($('input[name=password]').val() !== value)
            return '两次密码输入不一致！';
    }
});
