我是靠谱客的博主大力石头，最近开发中收集的这篇文章主要介绍一个简单的JS时间控件示例代码(JS时分秒时间控件)，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

自己在网上找了半天没找到只有 “时分秒”的控件，就自己做了个，发在这里方便有人用到

鼠标点击后的效果

SetTime.js

复制代码代码如下:

/**//***********************************
* 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)"/>
*
************************************/
var str = "";
document.writeln("<div id=/"_contents/" style=/"padding:6px; background-color:#E3E3E3; font-size: 12px; border: 1px solid #777777;  position:absolute; left:?px; top:?px; width:?px; height:?px; z-index:1; visibility:hidden/">");
str += "/u65f6<select name=/"_hour/">";
for (h = 0; h <= 9; h++) {
    str += "<option value=/"0" + h + "/">0" + h + "</option>";
}
for (h = 10; h <= 23; h++) {
    str += "<option value=/"" + h + "/">" + h + "</option>";
}
str += "</select> /u5206<select name=/"_minute/">";
for (m = 0; m <= 9; m++) {
    str += "<option value=/"0" + m + "/">0" + m + "</option>";
}
for (m = 10; m <= 59; m++) {
    str += "<option value=/"" + m + "/">" + m + "</option>";
}
str += "</select> /u79d2<select name=/"_second/">";
for (s = 0; s <= 9; s++) {
    str += "<option value=/"0" + s + "/">0" + s + "</option>";
}
for (s = 10; s <= 59; s++) {
    str += "<option value=/"" + s + "/">" + s + "</option>";
}
str += "</select> <input name=/"queding/" type=/"button/" onclick=/"_select()/" value=/"/u786e/u5b9a/" style=/"font-size:12px/" /></div>";
document.writeln(str);
var _fieldname;
function _SetTime(tt) {
    _fieldname = tt;
    var ttop = tt.offsetTop;    //TT控件的定位点高
    var thei = tt.clientHeight;    //TT控件本身的高
    var tleft = tt.offsetLeft;    //TT控件的定位点宽
    while (tt = tt.offsetParent) {
        ttop += tt.offsetTop;
        tleft += tt.offsetLeft;
    }
    document.all._contents.style.top = ttop + thei + 4;
    document.all._contents.style.left = tleft;
    document.all._contents.style.visibility = "visible";
}
function _select() {
    _fieldname.value = document.all._hour.value + ":" + document.all._minute.value + ":" + document.all._second.value;
    document.all._contents.style.visibility = "hidden";
}
