纯JS实现时分秒时间选择控件示例

JS时分秒时间控件示例

由于在网上难以找到仅支持“时分秒”格式的时间控件，作者自行开发了一个，并分享在此以方便他人使用。

鼠标点击输入框后，控件弹出的效果如下图所示。

SetTime.js

/**//***********************************
* 使用说明：
* 首先把本控件包含到页面
* <script src="XXX/setTime.js" type="text/javascript"></script>
* 控件调用函数：_SetTime(field)
* 例如 <input name="time" type="text" onclick="_SetTime(this)"/>
*
