JavaScript就这么回事5：窗口和框架
54 改变浏览器状态栏文字提示
1: <script language=”JavaScript”>
2: window.status = “A new status message”;
3: </script>
55 弹出确认提示框
1: <script language=”JavaScript”>
2: var userChoice = window.confirm(“Click OK or Cancel”);
8: </script>
56 提示输入
1: <script language=”JavaScript”>
2: var userName = window.prompt(“Please Enter Your Name”,”Enter Your Name Here”);
3: document.write(“Your Name is “ + userName);
4: </script>
57 打开一个新窗口
1: //打开一个名称为myNewWindow的浏览器新窗口
2: <script language=”JavaScript”>
3: window.open(“http://www.liu21st.com/”,”myNewWindow”);
4: </script>
58 设置新窗口的大小
1: <script language=”JavaScript”>
2: window.open(“http://www.liu21st.com/”,”myNewWindow”,'height=300,width=300');
3: </script>
59 设置新窗口的位置
1: <script language=”JavaScript”>
2: window.open(“http://www.liu21st.com/”,”myNewWindow”,'height=300,width=300,left=200,screenX=200,top=100,screenY=100');
3: </script>
60 是否显示工具栏和滚动栏
1: <script language=”JavaScript”>
2: window.open(“http:
61 是否可以缩放新窗口的大小
1: <script language=”JavaScript”>
2: window.open('http://www.liu21st.com/' , 'myNewWindow', 'resizable=yes' );</script>
62 加载一个新的文档到当前窗口
1: <a href='#' onClick='document.location = '125a.html';' >Open New Document</a>
63 设置页面的滚动位置
1: <script language=”JavaScript”>
64 在IE中打开全屏窗口
1: <a href='#' onClick=”window.open('http://www.juxta.com/','newWindow','fullScreen=yes');”>Open a full-screen window</a>
65 新窗口和父窗口的操作
1: <script language=”JavaScript”>
2: //定义新窗口
3: var newWindow = window.open(“128a.html”,”newWindow”);
4: newWindow.close(); //在父窗口中关闭打开的新窗口
5: </script>
6: 在新窗口中关闭父窗口
7: window.opener.close()
66 往新窗口中写内容
1: <script language=”JavaScript”>
2: var newWindow = window.open(“”,”newWindow”);
3: newWindow.document.open();
4: newWindow.document.write(“This is a new window”);
5: newWIndow.document.close();
6: </script>
67 加载页面到框架页面
1: <frameset cols=”50%,*”>
2: <frame name=”frame1” src="/”135a.html"”>
3: <frame name=”frame2” src="/”about:blank"”>
4: </frameset>
5: 在frame1中加载frame2中的页面
6: parent.frame2.document.location = “135b.html”;
68 在框架页面之间共享脚本
如果在frame1中html文件中有个脚本
那么在frame2中可以如此调用该方法
1: <body onLoad=”parent.frame1.doAlert();”>
2: This is frame 2.
3: </body>
69 数据公用
可以在框架页面定义数据项，使得该数据可以被多个框架中的页面公用
1: <script language=”JavaScript”>
2: var persistentVariable = “This is a persistent value”;
3: </script>
4: <frameset cols=”50%,*”>
5: <frame name=”frame1” src="/”138a.html"”>
6: <frame name=”frame2” src="/”138b.html"”>
7: </frameset>
这样在frame1和frame2中都可以使用变量persistentVariable
70 框架代码库
根据以上的一些思路，我们可以使用一个隐藏的框架页面来作为整个框架集的代码库
1: <frameset cols=”0,50%,*”>
2: <frame name=”codeFrame” src="/”140code.html"”>
3: <frame name=”frame1” src="/”140a.html"”>
4: <frame name=”frame2” src="/”140b.html"”>
5: </frameset>
1: <body onUnload=”functionName();”>
2: Body of the page
3: </body>

58 设置新窗口的大小
1: <script language=”JavaScript”>
2: window.open(“http://www.liu21st.com/”,”myNewWindow”,'height=300,width=300');
3: </script>
59 设置新窗口的位置
1: <script language=”JavaScript”>
2: window.open(“http://www.liu21st.com/”,”myNewWindow”,'height=300,width=300,left=200,screenX=200,top=100,screenY=100');
3: </script>
60 是否显示工具栏和滚动栏
1: <script language=”JavaScript”>
2: window.open(“http:
61 是否可以缩放新窗口的大小
1: <script language=”JavaScript”>
2: window.open('http://www.liu21st.com/' , 'myNewWindow', 'resizable=yes' );</script>
62 加载一个新的文档到当前窗口
1: <a href='#' onClick='document.location = '125a.html';' >Open New Document</a>
63 设置页面的滚动位置
1: <script language=”JavaScript”>
64 在IE中打开全屏窗口
1: <a href='#' onClick=”window.open('http://www.juxta.com/','newWindow','fullScreen=yes');”>Open a full-screen window</a>
65 新窗口和父窗口的操作
1: <script language=”JavaScript”>
2: //定义新窗口
3: var newWindow = window.open(“128a.html”,”newWindow”);
4: newWindow.close(); //在父窗口中关闭打开的新窗口
5: </script>
6: 在新窗口中关闭父窗口
7: window.opener.close()
66 往新窗口中写内容
1: <script language=”JavaScript”>
2: var newWindow = window.open(“”,”newWindow”);
3: newWindow.document.open();
4: newWindow.document.write(“This is a new window”);
5: newWIndow.document.close();
6: </script>
67 加载页面到框架页面
1: <frameset cols=”50%,*”>
2: <frame name=”frame1” src="/”135a.html"”>
3: <frame name=”frame2” src="/”about:blank"”>
4: </frameset>
5: 在frame1中加载frame2中的页面
6: parent.frame2.document.location = “135b.html”;
68 在框架页面之间共享脚本
如果在frame1中html文件中有个脚本
那么在frame2中可以如此调用该方法
1: <body onLoad=”parent.frame1.doAlert();”>
2: This is frame 2.
3: </body>
69 数据公用
可以在框架页面定义数据项，使得该数据可以被多个框架中的页面公用
1: <script language=”JavaScript”>
2: var persistentVariable = “This is a persistent value”;
3: </script>
4: <frameset cols=”50%,*”>
5: <frame name=”frame1” src="/”138a.html"”>
6: <frame name=”frame2” src="/”138b.html"”>
7: </frameset>
这样在frame1和frame2中都可以使用变量persistentVariable
70 框架代码库
根据以上的一些思路，我们可以使用一个隐藏的框架页面来作为整个框架集的代码库
1: <frameset cols=”0,50%,*”>
2: <frame name=”codeFrame” src="/”140code.html"”>
3: <frame name=”frame1” src="/”140a.html"”>
4: <frame name=”frame2” src="/”140b.html"”>
5: </frameset>
