5: <option value=”Third Choice”>3</option>
6: </select>
7: </form>
8: <a href='#' onClick='alert(document.myForm.mySelect.value);'>Check Selection List</a>
48 动态增加Select项
1: <form name=”myForm”>
2: <select name=”mySelect”>
3: <option value=”First Choice”>1</option>
4: <option value=”Second Choice”>2</option>
5: </select>

7: <script language=”JavaScript”>
8: document.myForm.mySelect.length++;
9: document.myForm.mySelect.options[document.myForm.mySelect.length - 1].text = “3”;
10: document.myForm.mySelect.options[document.myForm.mySelect.length - 1].value = “Third Choice”;
11: </script>
49 验证表单字段
1: <script language=”JavaScript”>
2: function checkField(field) {
3: if (field.value == “”) {
4: window.alert(“You must enter a value in the field”);
5: field.focus();
6: }
7: }
8: </script>
9: <form name=”myForm” action=”target.html”>

6: newItem += item.charCodeAt(i) + '.';
7: }
8: return newItem;
9: }
10: function encryptForm(myForm) {
11: for (i=0; i < myForm.elements.length; i++) {
12: myForm.elements[i].value = encrypt(myForm.elements[i].value);
13: }
14: }
15:
16: //-->
17: </SCRIPT>
18: <form name='myForm' onSubmit='encryptForm(this); window.alert(this.myField.value);'>
19: Enter Some Text: <input type=text name=myField><input type=submit>
20: </form>
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”);
3: if (userChoice) {
4: document.write(“You chose OK”);
5: } else {
6: document.write(“You chose Cancel”);
7: }
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”>
2: if (document.all) { //如果是IE浏览器则使用scrollTop属性
3: document.body.scrollTop = 200;
4: } else { //如果是NetScape浏览器则使用pageYOffset属性
5: window.pageYOffset = 200;
6: }</script>
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
1: function doAlert() {
2: window.alert(“Frame 1 is loaded”);
3: }
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>

3: <option value=”First Choice”>1</option>
4: <option value=”Second Choice”>2</option>

10: document.myForm.mySelect.options[document.myForm.mySelect.length - 1].value = “Third Choice”;
11: </script>
49 验证表单字段
1: <script language=”JavaScript”>
2: function checkField(field) {
3: if (field.value == “”) {
4: window.alert(“You must enter a value in the field”);

6: newItem += item.charCodeAt(i) + '.';
7: }
8: return newItem;
9: }
10: function encryptForm(myForm) {
11: for (i=0; i < myForm.elements.length; i++) {
12: myForm.elements[i].value = encrypt(myForm.elements[i].value);
13: }
14: }
15:
16: //-->
17: </SCRIPT>
18: <form name='myForm' onSubmit='encryptForm(this); window.alert(this.myField.value);'>
19: Enter Some Text: <input type=text name=myField><input type=submit>
20: </form>
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”);
3: if (userChoice) {
4: document.write(“You chose OK”);
5: } else {
6: document.write(“You chose Cancel”);
7: }
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”>
2: if (document.all) { //如果是IE浏览器则使用scrollTop属性
3: document.body.scrollTop = 200;
4: } else { //如果是NetScape浏览器则使用pageYOffset属性
5: window.pageYOffset = 200;
6: }</script>
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
1: function doAlert() {
2: window.alert(“Frame 1 is loaded”);
3: }
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>
