摘要: JavaScript精简学习2：浏览器输出
26 访问document对象
1: <script language=”JavaScript”>
2: var myURL = document.URL;
3: window.alert(myURL);
4: </script>
27 动态输出HTML
1: <script language=”JavaScript”>
2: document.write(“
Here’s some information about this document:
”);3: document.write(“
- ”);
- Referring Document: “ + document.referrer + “ ”);
- Domain: “ + document.domain + “ ”);
- URL: “ + document.URL + “ ”);
4: document.write(“
5: document.write(“
6: document.write(“
7: document.write(“
8: </script>
28 输出换行
1: document.writeln(“a”);
2: document.writeln(“b”);
29 输出日期
1: <script language=”JavaScript”>
2: var thisDate = new Date();
3: document.write(thisDate.toString());
4: </script>
30 指定日期的时区
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 设置日期输出格式
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 读取URL参数
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>
你还以为HTML是无状态的么？
33 打开一个新的document对象
1: <script language=”JavaScript”>
2: function newDocument() {
3: document.open();
4: document.write(“
This is a New Document.
”);5: document.close();
6: }
7: </script>
34 页面跳转
1: <script language=”JavaScript”>
2: window.location = “[url]http://www.liu21st.com/[/url]”;
3: </script>
35 添加网页加载进度窗口
1:
2: <head>
3: <script language='javaScript'>
4: var placeHolder = window.open('holder.html','placeholder','width=200,height=200');
5: </script>
6:
7: </head>
8: <body onLoad='placeHolder.close()'>
9:
This is the main page
10: </body>
11: </td> </tr> </table>
