js使用方法小結(jié)，比較不錯，無論是新手，還是老手都是不錯的。

26 訪問document對象
1: <script language="JavaScript">
2: var myURL = document.URL;
3: window.alert(myURL);
4: </script>
27 動態(tài)輸出HTML
1: <script language="JavaScript">
2: document.write(“<p>Here's some information about this document:</p>");
3: document.write(“<ul>");
4: document.write(“<li>Referring Document: “ + document.referrer + “</li>");
5: document.write(“<li>Domain: “ + document.domain + “</li>");
6: document.write(“<li>URL: “ + document.URL + “</li>");
7: document.write(“</ul>");
8: </script>
28 輸出換行
1: document.writeln(“<strong>a</strong>");
2: document.writeln(“b");
29 輸出日期
1: <script language="JavaScript">
2: var thisDate = new Date();
3: document.write(thisDate.toString());
4: </script>
30 指定日期的時區(qū)
1: <script language="JavaScript">
2: var myOffset = -2;
3: var currentDate = new Date();
4: var userOffset = currentDate.getTimezoneOffset()/60;
5: var timeZoneDifference = userOffset - myOffset;
6: currentDate.setHours(currentDate.getHours() + timeZoneDifference);
7: document.write(“The time and date in Central Europe is: “ + currentDate.toLocaleString());
8: </script>
31 設(shè)置日期輸出格式
1: <script language="JavaScript">
2: var thisDate = new Date();
3: var thisTimeString = thisDate.getHours() + “:" + thisDate.getMinutes();
4: var thisDateString = thisDate.getFullYear() + “/" + thisDate.getMonth() + “/" + thisDate.getDate();
5: document.write(thisTimeString + “ on “ + thisDateString);
6: </script>
32 讀取URL參數(shù)
1: <script language="JavaScript">
2: var urlParts = document.URL.split(“?");
3: var parameterParts = urlParts[1].split(“&");
4: for (i = 0; i < parameterParts.length; i++) {
5: var pairParts = parameterParts[i].split(“=");
6: var pairName = pairParts[0];
7: var pairValue = pairParts[1];
8: document.write(pairName + “ ：“ +pairValue );
9: }
10: </script>
你還以為HTML是無狀態(tài)的么？
33 打開一個新的document對象
