jQuery实现的简单日历组件定义与用法示例

Jafeney 2020-05-16 我要评论

本文实例讲述了jQuery实现的简单日历组件定义与用法。分享给大家供大家参考，具体如下：

说到日历组件，网上一搜一大堆，各种插件啊、集成框架啊实在不少。但是插件有的不合需求，框架嘛依赖关系一大堆，比如jQueryUI、bootstrap等。其实现在我就是想要一个轻量级的日历组件，功能也不需要很强大，只要能兼容所有浏览器，能选择任意年份日期和星期就可以了。

好了，废话不多说，直接上代码：

好了，先引入jQuery库。（发表一下感概：angularJS的数据双向绑定着实让我对jQuery的未来担忧了一阵子，不过jQuery毕竟存在的时间很久，API文档和应用方面实在太广泛了 * _ *，而且jQuery无可厚非是一款相当不错的DOM操作类库，至少我觉得段时间内这个地位无可动摇。所以大家还是大胆地用吧！）

<script type="text/javascript" src="./js/jQuery.min.js"></script>

下面这个是还没压缩的js文件，纯手写哦 ^_^

下面是我写的简单的一套样式风格，有点模仿微信的风格。

/*dateField styles*/
/*reset*/
ul,li{
  list-style: none;
  padding:0;
  margin:0;
}
/*default*/
.dateField-container{
  position:absolute;
  width:210px;
  border:1px solid rgb(229,229,229);
  z-index:99999;
  background:#fff;
  font-size:13px;
  margin-top:0px;
  cursor: pointer;
  display:none;
}
.dateField-header{
  width:212px;
  position:relative;
  left:-1px;
}
.dateField-header-btns{
  width:100%;
  height:30px;
  text-align:center;
  background:rgb(243,95,143);
}
.btn{
  user-select:none;
  -webkit-user-select:none;
  -moz-user-select:none;
  -ms-user-select:none;
}
.dateField-header-btn-left{
  float: left;
  display:block;
  width:30px;
  height:30px;
  color:#fff;
  line-height:30px;
}
.dateField-header-btn-left:hover{
  background:rgb(238,34,102);
}
.dateField-header-datePicker{
  display:inline-block;
  width:120px;
  text-align:center;
  color:#fff;
  line-height:30px;
}
.dateField-header-datePicker:hover{
  background:rgb(238,34,102);
}
.dateField-header-btn-right{
  float: right;
  width:30px;
  height:30px;
  display:block;
  color:#fff;
  line-height:30px;
}
.dateField-header-btn-right:hover{
  background:rgb(238,34,102);
}
.dateField-header-week{
  clear:both;
  width:100%;
  height:26px;
}
.dateField-header-week li{
  float: left;
  width:30px;
  height:30px;
  line-height:30px;
  text-align:center;
}
.dateField-body{
  width:100%;
}
.dateField-body-days{
  clear: both;
}
.dateField-body-days li{
  float: left;
  width:30px;
  height:30px;
  box-sizing:border-box;
  -webkit-box-sizing:border-box;
  -ms-box-sizing:border-box;
  -moz-box-sizing:border-box;
  border-top:1px solid rgb(229,229,229);
  border-right:1px solid rgb(229,229,229);
  line-height:30px;
  text-align:center;
}
.dateField-body-days li:hover{
  color:#fff;
  background:rgb(243,95,143);
}
.dateField-body-days li.active{
  color:#fff;
  background:rgb(243,95,143);
}
.dateField-body-days li.last{
  border-right:0;
}
.dateField-footer{
  border-top:1px solid rgb(229,229,229);
  clear:both;
  width:100%;
  height:26px;
  font-size:12px;
}
.dateField-footer-close{
  margin-top:2px;
  display:inline-block;
  width:100%;
  height:22px;
  background:rgb(245,245,245);
  text-align: center;
  line-height:22px;
}
.dateField-footer-close:hover{
  background:rgb(238,238,238);
}
.dateField-select{
  user-select:none;
  -webkit-user-select:none;
  -ms-user-select:none;
  -moz-user-select:none;
}
.dateField-body-months{
}
.dateField-body-months li{
  width:70px;
  height:35px;
  line-height:35px;
}
.dateField-body-years li{
  width:70px;
  height: 35px;
  line-height: 35px;
}

到了最关键的时刻，怎么使用呢？嘿嘿，就2行代码。

  <!-- input group -->
  <div class="input-group">
    <input type="text" id="input-date" class="input-text">
  </div>
  <!--end input group-->
  <script type="text/javascript">
    ;$(function(){
      $('#input-date').dateField({
        eventType:'click',
        style:'default'
      })
    });
  </script>
