Selenium IDE 扩展函数：日期计算与表现

　　用Selenium IDE做网页的功能测试经常会碰到与日期有关的验证，本人结合实际工作中遇到的应用，写了一个扩展，代码如下：

　　Selenium.prototype.doStoreDateByFormat = function(format,args){

　　// format of args: month,day,year

　　if(args.trim().length < 3)

　　throw new SeleniumError("arguments must contain ""Month"",""Date"",""Year"" variables!");

　　var formats = format.split(",");

　　var days = parseInt(formats[3]);

　　var sysDate = getSysDate(); //get the sysdate

　　var specDate = dateAfterDays(sysDate,parseFloat(days),1); //get specified date

　　var arrArgs = args.split(",");

　　var month = specDate.getMonth()+1;

　　var date = specDate.getDate();

　　var year = specDate.getFullYear();

　　// get Month string

　　switch(formats[0].toUpperCase()){

　　case "MM": // return 2 digits of month number, such as: 01

　　month = (month+"").length==1?"0"+month:month;

　　break;

　　case "MMM": //return the first 3 chars of the month word, such as: Jan

　　month = this.getMonthShortName(month);

　　break;

　　case "MMMM": //return the full word of the month word, such as: January

　　month = this.getMonthFullName(month);

　　break;

　　case "M":

　　default:

　　// return 1 digit when month is lower than 10.

　　// do nothing

　　}

　　//get Date string

　　switch(formats[1].toUpperCase()){

　　case "DD": //always return 2 digits of the month number, such as: 05

　　date = (date+"").length==1?"0"+date:date;

　　break;

　　case "D":

　　default:

　　// return 1 digit when Date is lower than 10.

　　// do nothing

　　}

　　//get Year string

　　switch(formats[2].toUpperCase()){

　　case "YY": // return last 2 digits of the year number, such as: 08 (2008)

　　year = (year+"").substr(2);

　　break;

　　case "YYYY":

　　default:

　　//return full year number, such: 2008.

　　}

　　storedVars[arrArgs[0]] = month;

　　storedVars[arrArgs[1]] = date;

　　storedVars[arrArgs[2]] = year;

　　}

　　Selenium.prototype.getMonthFullName = function(month){

　　var monthArr = new Array("January","February","March","April","May","June","July","August","September","October","November","December");

　　if(month == null){

　　throw new SeleniumError("you didn't specify a Month");

　　}

　　try{

　　month = parseInt(month);

　　}catch (e){

　　throw new SeleniumError("""Month"" is not a Integer!");

　　}

　　return monthArr[month-1];

　　}

　　/* return the date N days(N*24 hours) before/after some day.

　　* args : num - positive/negative integer/float number,default is "1";

　　* type - 0 (second) or 1 (day), default is second.

　　* return : Date

　　*/

　　function dateAfterDays(date, num, type){

　　date = (date == null?new Date():date);

　　num = (num == null?1:num);

　　if(typeof(num)!="number")

　　throw new SeleniumError("dateAfterDays(date, num, type),""num"" argument must be Number type.");

　　if(typeof(date)!="object")

　　throw new SeleniumError("dateAfterDays(date, num, type),""date"" argument must be Date type.");

　　var iType = (type == null?0:type);

　　var arr = [1000,86400000];

　　var dd = date.valueOf();

　　dd += num * arr[iType];

　　var d=new Date(dd);

　　return d;

　　}

　　function getSysDate(){

　　return new Date();

　　}
