document 文挡对象详解(JavaScript脚本语言描述)
 
:页面上元素name属性和JavaScript引用的名称必须一致包括大小写,否则会提示你一个错误信息 "引用的元素为空或者不是对象"]
========================================================================
对象属性:

document.bgColor              //设置页面背景色
document.fgColor              //设置前景色(文本颜色)
document.linkColor            //未点击过的链接颜色
document.alinkColor            //激活链接(焦点在此链接上)的颜色
document.vlinkColor           //已点击过的链接颜色
document.URL                  //设置URL属性从而在同一窗口打开另一网页
document.fileCreatedDate      //文件建立日期,只读属性
document.fileModifiedDate     //文件修改日期,只读属性
document.fileSize             //文件大小,只读属性
document.cookie               //设置和读出cookie
document.charset              //设置字符集 简体中文:gb2312
----------------------------
常用对象方法:

document.body.appendChild (oTag) //动态生成一个HTML对象
----------------------------
常用对象事件:

document.body.onclick="func()"             //鼠标指针单击对象是触发
document.body.onmouseover="func()"         //鼠标指针移到对象时触发
document.body.onmouseout="func()"          //鼠标指针移出对象时触发
========================================================================

========================================================================
selection-选区子对象
document.selection
========================================================================
images集合(页面中的图象):
----------------------------
a)通过集合引用
document.images                //对应页面上的<img>标签
document.images.length         //对应页面上<img>标签的个数

d)创建一个图象
var oImage
oImage = new Image()
document.images.oImage.src="1.jpg"
同时在页面上建立一个<img>标签与之对应就可以显示
----------------------------
示例代码(动态创建图象):

3: <option value="First Choice">1</option>  
4: <option value="Second Choice">2</option>  
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>  
6: </form>  
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">  
10: Text Field: <input type="text" name="myField"onBlur="checkField(this)">  
11: <br><input type="submit">  
12: </form>   


50 验证Select项  

1: function checkList(selection) {   
2: if (selection.length == 0) {   
3: window.alert("You must make a selection from the list.");  
4: return false;  
5: }  
6: return true;  
7: }   


51 动态改变表单的action  

1: <form name="myForm" action="login.html">  
2: Username: <input type="text" name="username"><br>  
3: Password: <input type="password" name="password"><br>  
4: <input type="button" value="Login" onClick="this.form.submit();">  
5: <input type="button" value="Register" onClick="this.form.action = 'register.html'; this.form.submit();">  
6: <input type="button" value="Retrieve Password" onClick="this.form.action = 'password.html'; this.form.submit();">  
7: </form>   


52 使用图像按钮  

1: <form name="myForm" action="login.html">  
2: Username: <input type="text" name="username"><br>  
3: Password: <input type="password"name="password"><br>  
4: <input type="image" src="/"login.gif"" value="Login">  
5: </form>  
6:   


53 表单数据的加密  

1: <SCRIPT LANGUAGE='JavaScript'>  
2: <!--  
3: function encrypt(item) {   
4: var newItem = '';  
5: for (i=0; i < item.length; i++) {   
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>
