今天给网页加个JS时间生成器，方便用户选取时间查询。其实整体代码很简单，原理就不说了 ?直接拿来用

function HS_DateAdd(interval,number,date){

number = parseInt(number);

if (typeof(date)==”string”){var date = new Date(date.split(“-“)[0],date.split(“-“)[1],date.split(“-“)[2])}

if (typeof(date)==”object”){var date = date}

switch(interval){

case “y”:return new Date(date.getFullYear()+number,date.getMonth(),date.getDate()); break;

case “m”:return new Date(date.getFullYear(),date.getMonth()+number,checkDate(date.getFullYear(),date.getMonth()+number,date.getDate())); break;

case “d”:return new Date(date.getFullYear(),date.getMonth(),date.getDate()+number); break;

case “w”:return new Date(date.getFullYear(),date.getMonth(),7*number+date.getDate()); break;

}

function checkDate(year,month,date){

var enddate = [“31″,”28″,”31″,”30″,”31″,”30″,”31″,”31″,”30″,”31″,”30″,”31”];

var returnDate = “”;

if (year%4==0){enddate[1]=”29″}

if (date>enddate[month]){returnDate = enddate[month]}else{returnDate = date}

return returnDate;

}

function WeekDay(date){

var theDate;

if (typeof(date)==”string”){theDate = new Date(date.split(“-“)[0],date.split(“-“)[1],date.split(“-“)[2]);}

if (typeof(date)==”object”){theDate = date}

return theDate.getDay();

}

function HS_calender(){

var lis = “”;

var style = “”;

style +=”<style type=’text/css’>”;

style +=”.calender { width:170px; height:auto; font-size:12px; margin-right:14px; background:url(calenderbg.gif) no-repeat right center #fff; border:1px solid #397EAE; padding:1px}”;

if (arguments.length>1){

}

function _selectThisDay(d){

var boxObj = d.parentNode.parentNode.parentNode.parentNode.parentNode;

boxObj.targetObj.value = d.title;

boxObj.parentNode.removeChild(boxObj);

}

function closeCalender(d){

var boxObj = d.parentNode.parentNode.parentNode;

boxObj.parentNode.removeChild(boxObj);

}

function CalenderselectYear(obj){

var opt = “”;

var thisYear = obj.innerHTML;

for (i=1970; i<=2020; i++){

if (i==thisYear){

opt += “<option value=”+i+” selected>”+i+”</option>”;

}else{

opt += “<option value=”+i+”>”+i+”</option>”;

}

opt = “<select onblur=’selectThisYear(this)’ onchange=’selectThisYear(this)’ style=’font-size:11px’>”+opt+”</select>”;

obj.parentNode.innerHTML = opt;

}

function selectThisYear(obj){

HS_calender(obj.value+”-“+obj.parentNode.parentNode.getElementsByTagName(“span”)[1].getElementsByTagName(“a”)[0].innerHTML+”-1″,obj.parentNode);

}

function CalenderselectMonth(obj){

var opt = “”;

var thisMonth = obj.innerHTML;

for (i=1; i<=12; i++){

if (i==thisMonth){

opt += “<option value=”+i+” selected>”+i+”</option>”;

}else{

opt += “<option value=”+i+”>”+i+”</option>”;

}

opt = “<select onblur=’selectThisMonth(this)’ onchange=’selectThisMonth(this)’ style=’font-size:11px’>”+opt+”</select>”;

obj.parentNode.innerHTML = opt;

}

function selectThisMonth(obj){

HS_calender(obj.parentNode.parentNode.getElementsByTagName(“span”)[0].getElementsByTagName(“a”)[0].innerHTML+”-“+obj.value+”-1″,obj.parentNode);

}

function HS_setDate(inputObj){

var calenderObj = document.createElement(“span”);

calenderObj.innerHTML = HS_calender(new Date());

calenderObj.style.position = “absolute”;

calenderObj.targetObj = inputObj;

inputObj.parentNode.insertBefore(calenderObj,inputObj.nextSibling);

}

以上是JS函数把它保存成单独的JS文件，然后在需要的页面引入文件，在文本框的代码里面加上

onfocus=”HS_setDate(this)”

就可以了 ?例如

如果有乱码的话，自己做下修正或者直接把JS函数写在你的页面里，然后修改几个乱码地方就可以了
