開始這禮拜的進度之前，我們先將寫好的js程式整理至updateData.js (名字不需要一樣，但是一旦你用了自己的命名，後面要注意，命字的一致性。)
作法：
- 建立一個js目錄 (我們之前還沒有這個目錄)
- 在js目錄裏建立一個新檔，命名為updateData.js
- 將原本在index.html中<script></script>區塊中的程式碼剪下貼上到updateData.js(注意<script>標籤不要貼過去，也就是說js檔裏沒有HTML標籤。)
- 然後底下幾行，包裝成一個函式 updateCurrentDateInfoData()
- 在index.html中加入<script src="updateData.js">含入這個js檔。
document.getElementById("cur-date").innerHTML = getOrdinaryString ( today.getDate() );
document.getElementById("cur-day").innerHTML = getWeekdayName ( today.getDay() );
document.getElementById("cur-month").innerHTML = getMonthName ( today.getMonth() );
document.getElementById("cur-year").innerHTML = today.getFullYear();
document.getElementById("cal-year").innerHTML = today.getFullYear();
document.getElementById("cal-month").innerHTML = getMonthName ( today.getMonth() );
updateData.js
function getWeekdayName(day) {
if (day == 0) return "Sunday";
if (day == 1) return "Monday";
if (day == 2) return "Tuesday";
if (day == 3) return "Wednesday";
if (day == 4) return "Thursday";
if (day == 5) return "Friday";
if (day == 6) return "Saturday";
}
function getMonthName(month) {
console.log(month);
if (month == 0) return "January";
if (month == 1) return "February";
if (month == 2) return "March";
if (month == 3) return "April";
if (month == 4) return "May";
if (month == 5) return "June";
if (month == 6) return "July";
if (month == 7) return "August";
if (month == 8) return "September";
if (month == 9) return "October";
if (month == 10) return "November";
if (month == 11) return "December";
}
function getOrdinaryString(date) {
if (date == 1 || date == 21 || date == 31) return date + "<sup>st</sup>";
if (date == 2 || date == 22) return date + "<sup>nd</sup>";
if (date == 3 || date == 31) return date + "<sup>rd</sup>";
return date + "<sup>th</sup>";
}
function updateCurrentDateInfoData(){
document.getElementById("cur-date").innerHTML = getOrdinaryString ( today.getDate() );
document.getElementById("cur-day").innerHTML = getWeekdayName ( today.getDay() );
document.getElementById("cur-month").innerHTML = getMonthName ( today.getMonth() );
document.getElementById("cur-year").innerHTML = today.getFullYear();
document.getElementById("cal-year").innerHTML = today.getFullYear();
document.getElementById("cal-month").innerHTML = getMonthName ( today.getMonth() );
}
index.html的script片段 (不是所有的index.html碼)
<script src="js/updateData.js" charset="utf-8"></script>
<script type="text/javascript">
var today = new Date();
updateCurrentDateInfoData();
</script>
整理好之後，測試月曆網頁程式是否正常。
這個步驟，我們將index.html中寫好的js程式碼移動到獨立的個別檔案中，這是管理整個系統的一個方式，當程式碼數量增多，必須要妥善地管理這些程式碼，建立適當的目錄、檔案，甚至是多層的子目錄，如此一來，你的系統程式碼具有良好的結構，這對以後系統的維護會有很大幫助。
