这个时间组件以前发过一次,上次那个很烂,这次有时间了,把这个升级了,性能更好,完美兼容所有浏览器,ie6下拉select档不住的问题
也解决了.总之,差不多也算一个完美的时间组件,
在线demo nothingDemo 突然发现下面的代码里面有个运行代码可以看在线demo,就再最下面
然后贴出源码,只有一点简单的说明
代码如下:
Untitled Page red;display:block;margin:20px auto;width:300px;font-size:14px;padding:3px;">作者nothing
var nothingTime = (function ($) {
var cache = {
obj: null,
calendar: null,
disappear: function () { //隐藏时间块
cache.calendar.css("display", "none");
},
isLeap: function (year) { //闰年
return (year % 100 == 0 ? (year % 400 == 0 ? 1 : 0) : (year % 4 == 0 ? 1 : 0));
},
isValid: function (d) { //是否在今天以前
return (d.getTime() - (new Date()).getTime() < 0) ? true : false;
},
td: new Date(),
createData: function (year, month) {
var n1 = new Date(year, month, 1),
firstday = n1.getDay(),
mdays = [31, 28 + this.isLeap(year), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31],
ul = document.createElement("ul"), li;
ul.className = "days";
$("#calendar").find(".days").remove();
for (var i = firstday;i--;) { //建立前面无效的几天
ul.appendChild(document.createElement("li"));
}
for (var j = 1; j <= mdays[month]; j++) {
if (this.isValid(new Date(year, month, j))) { //今天以前的日子
li = document.createElement("li");
li.innerHTML = "" + j + "";
ul.appendChild(li);
} else {
li = document.createElement("li");
li.innerHTML = j;
ul.appendChild(li);
}
}
this.calendar[0].appendChild(ul);
},
change: function () { //给下拉列表绑定时间
var a = $("#calendar .month"),
b = $("#calendar .year");
a.change(function () {
cache.createData(b.attr("value"), $(this).attr("value"));
});
b.change(function () {
cache.createData($(this).attr("value"), a.attr("value"));
});
cache.calendar.delegate(".days a", "click", function () {
var day = b.attr("value") + "-" + (parseInt(a.attr("value")) + 1) + "-" + this.innerHTML;
cache.obj.val(day);
cache.disappear();
});
},
bodyClickDisappear: function () {
setTimeout(function () {
$("body").bind("click", cache.disappear);
}, "200");
},
calendarClick: function () {
cache.calendar.click(function (e) {
e.stopPropagation();
});
}
},
CreateTime = function (obj) {
cache.obj = obj;
var of = cache.obj.offset();
if (document.getElementById("calendar")) {
} else {
var se = "
日一二三四五六";
$("", { id: "calendar", html: se, "class": "pc_caldr" }).appendTo(document.body);
cache.calendar = $("#calendar");
if (/msie 6\.0/i.test(navigator.userAgent)) {
var iframe = document.createElement("iframe");
iframe.className = "ie6iframe";
cache.calendar[0].appendChild(iframe);
}
cache.change();
cache.bodyClickDisappear();
cache.calendarClick();
}
cache.createData(cache.td.getFullYear(), cache.td.getMonth());
cache.calendar.find(".year").attr("value", cache.td.getFullYear());
cache.calendar.find(".month").attr("value", cache.td.getMonth());
cache.calendar.css({ left: of.left, top: of.top + cache.obj.height() + 2, display: "block" });
};
return function (obj) {
CreateTime(obj);
};
})(jQuery);
//使用方法
$("input.tiemin").focus(function (e) {
nothingTime($(this));
}).click(function (e) {
e.stopPropagation();
});
OK,这个时间组件到此为止,下篇我应该讲点如何跟上js代码的脚步,ECMAScript5,我会试着模仿里面的方法,然后在ie6 7 8中运行,这样,前沿的js方法
我们照样不误.
