 隐藏脚本代码   

 <script language=”JavaScript”>  
 <!–  
 document.write(“Hello”);  
 // –>  
 </script>   

在不支持JavaScript的浏览器中将不执行相关代码   

 浏览器不支持的时候显示   

 <noscript>  
 Hello to the non-JavaScript browser.  
 </noscript>   
 链接外部脚本文件   

 <script language=”JavaScript” src="/”filename.js"”></script>

 // This is a comment  
 document.write(“Hello”); // This is a comment  
 /*  
 All of this  
 is a comment  
 */   

 输出到浏览器   

 document.write(“<strong>Hello</strong>”);

JavaScript就这么回事4：表单   

还是先继续写完JS就这么回事系列吧～  
43 表单构成   

1: <form method=”post” action=”target.html” name=”thisForm”>

4: </form>  
5: <a href=”#” onClick=”document.myForm.copyText.value =  
6: document.myForm.myText.value;”>Copy Text Field</a>   

46 侦测文本框的变化   

1: <form name=”myForm”>  
2: Enter some Text: <input type=”text” name=”myText” onChange=”alert(this.value);”>  
3: </form>   

47 访问选中的Select   

1: <form name=”myForm”>  
2: <select name=”mySelect”>  
3: <option value=”First Choice”>1</option>  
4: <option value=”Second Choice”>2</option>  
5: <option value=”Third Choice”>3</option>  
6: </select>

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:

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.velee.cn”,”myNewWindow”);  
4: </script>   

58 设置新窗口的大小   

1: <script language=”JavaScript”>  
2: window.open(“http://www.velee.cn”,”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.velee.cn”,”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.velee.cn' , '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>   

   

教程：事半功倍系列之javascript From:向东IT博客   
本文由经典论坛 邓永炎 整理   

清华大学出版的《事半功倍系列 javascript》,本人照着书敲出来的,有些翻译了一下.前几年看了一下,最近无事,重新翻了翻,很有帮助.本书应该有光盘的,但学校的书,光盘不知在哪.希望对你学 javascript有帮助   

第一章javascript简介   

1.在地址栏输入javascript语句   

Javascript:Document.write("显示文字")   

2.将javascript嵌入 HTML文档   

<script language=javascript>  
document.bgColor="blue"  
</script>   

第二章 使用变量和数组   

1.声明变量   

<script language=javascripe>  
Var answer1,answer2,answer3,answer4;  
answer1=9;  
answer2=2.5  
answer3="Milkey May"  
answer4=true  
</script>   

2.使用整数   

<script language=javascript>  
var decimalNum,hexadecimalNum,octalNum  
decimalNum=24  
hexadecimalNum=0×24  
octalNum=024  
document.write("显示十进制数："+ decimalNum+"<br>")  
document.write("显示十六进制数："+ hexadecimalNum +"<br>")  
document.write("显示八进制数："+ octalNum +"<br>")  
</script>   

3.使用浮点数   

<script language=javascript>  
var num1,num2,num3,num4  
num1=1234567890000.0  
num2=5.14e23  
num3=0.0000123456  
num4=6.0254e3-4  
document.write("浮点数1："+num1+"<br>")  
document.write("浮点数2："+num2+"<br>")  
document.write("浮点数3："+num3+"<br>")  
document.write("浮点数4："+num4+"<br>")  
</script>   

4.使用布尔值   

<script language=javascript>  
var answer1,answer2  
answer1=true  
answer2=false  
document.write("显示布尔1："+answer1+"<br>")  
document.write("显示布尔2："+answer2+"<br>")  
</script>   

5.使用字符串   

<script language=javascript>  
var str1,str2  
str1="fdsgdg dsfdsf china"  
str2="武汉市广播电视大学"  
document.write("显示字符串1："+str1+"<br>")  
document.write("显示字符串2："+str2+"<br>")  
</script>   

6.确定变量类型   

<script>  
var answer1,answer2,answer3,answer4  
answer1=9  
answer2=2.5  
answer3="milky may"  
answer4=true  
document.write("变量1的类型是："+typeof answer1 +"<br>")  
document.write("变量2的类型是："+typeof answer2 +"<br>")  
document.write("变量3的类型是："+typeof answer3 +"<br>")  
document.write("变量4的类型是："+typeof answer4 +"<br>")  
</script>   

7.将字符串转换成数字   

<script>  
var str1="31 days in january"  
var int1=parseInt(str1)  
document.write("str1的数据类型是 ："+typeof str1+"<br>")  
document.write("int1的数据类型是 ："+typeof int1+"<br>")  
</script>   

8.将数字转换成字符串   

<script>  
var int1=256  
var str1=""+int1  
document.write("str1的数据类型是 ："+typeof str1+"<br>")  
document.write("int1的数据类型是 ："+typeof int1+"<br>")  
</script>   

9.声明数组   

<script>  
array=new Array(5)  
array[0]=1  
array[1]=3  
array[2]=5  
array[3]=7

document.write(str1+"<br>")  
</script>   

第三章 创建表达式   

本文摘自:拾金者(http://www.xkde.com) 详细出处参考：http://www.xkde.com/WapContent-199-9524.aspx?ppp=1

1.使用算术运算符   

<script>  
var1=12  
var2=10  
varadd=var1+var2  
varsub=var1-var2  
varmult=var1*var2  
vardiv=var1/var2  
varmod=var1%var2  
document.write("数据1是："+var1+"<br>")  
document.write("数据2是："+var2+"<br>")  
document.write("数据相加是："+varadd+"<br>")  
document.write("数据相减是："+varsub+"<br>")  
document.write("数据相乘是："+varmult+"<br>")  
document.write("数据相除是："+vardiv+"<br>")  
document.write("数据相除取余数是："+varmod+"<br>")  
</script>   

2.递增变量和递减变量   

<script>  
days=1  
document.write("输出变量"+days+"<br>")  
days++  
document.write("递增后变量变为："+days)  
</script>   

3.创建比较表达式   

<script>  
daysofmonth=28  
if(daysofmonth==28)  
month="february"  
document.write("days of month:"+daysofmonth+"<br>")  
document.write("month:"+month)  
</script>   

4.创建逻辑表达式   

<script>  
dayofmonth=28  
if(dayofmonth==28 || dayofmonth==29)  
month="february"  
document.write("days of month:"+dayofmonth+"<br>")  
document.write("month:"+month)  
</script>   

5.使用条件运算符   

<script language="javascript">  
stomach="hungry";  
time="5:00";  
(stomach=="hungry"&&time=="5:00") ? eat = "dinner":eat="a snack";  
document.write("输出结果"+eat);  
</script>   

6.识别数字   

<script>  
var1=24;  
(isNaN(var1))?document.write("变量var1"+var1+"不是数字"):Document.write("变量var1"+var1+"是数字")  
</script>   

第四章 控制程序流程   

1.使用IF –Else语句   

<script>  
month="december"  
date=25  
if(month=="december" && date==25)  
document.write("今天是圣诞节,商店关门")  
else  
document.write("欢迎,您来商店购物")  
</script>   

2.使用for 循环   

<script>  
for (count=1;count<=10;count++)  
document.write("输出第"+count+"句"+"<br>")  
</script>   

3.使用while循环   

<script>  
count=1  
while(count<=15){  
document.write("输出第"+count+"句" +"<br>")  
count++}  
</script>   

4.中断循环   

<script>  
count=1  
while(count<=15){  
count++  
if(count==8)  
break;  
document.write("输出第"+count+"句"+"<br>")}  
</script>   

5.继续循环   

<script>  
count=1  
while(count<=15){  
count++  
if(count==8)  
continue;  
document.write("输出第"+count+"句"+"<br>")}  
</script>   

6.使用javascript定时器   

<script>  
function rabbit()  
{document.write("输出语句")  
}  
</script>  
<body onload=window.setTimeout(rabbit(),5000)>   

7.设置定期间隔   

<script>  
window.setInterval("document.form1.text2.value=document.form1.text1.value",3000)  
</script>  
<form name=form1>  
<input type=text name=text1><br>  
<input type=text name=text2><br>  
</form>   

8.清除超时和间隔   

<script>  
stop=window.setInterval("document.form1.text2.value=document.form1.text1.value",300)  
</script>  
<form name=form1>  
<input type=text name=text1><br>  
<input type=text name=text2><br>  
<input type=button name=button1 value=" 清除超时和间隔" onclick=clearInterval(stop)>  
</form>   

第五章 使用函数

}  
</script>   

2.调用函数   

<script>  
function quote()  
{ document.write("输出语句")  
}  
quote()  
</script>   

3.了解全局变量和局部变量   

任何不用 var关键字声明的变量都是全局变量,任何在函数外声明的变量都是全局变量   

4.将参数传送给函数   

<script>  
function f(item)  
{document.write("输出参数"+item+"<br>")  
}  
f("fgdfgd")  
f("参数二")  
</script>   

5.从函数返回值   

<script>  
function average(var1,var2,var3)  
{ave=(var1+var2+var3)/3;  
document.write("输出结果");  
return ave;  
}  
document.write(average(34,56,78))  
</script>   

6.通过HTML链接调用函数   

<script>  
function quote(){  
document.write(" 输出字符串")  
}  
</script>  
<a href=javascript:quote()>通过HTML链接调用函数</a>  
<a href=javascript:Document.write("输出字符")> 通过HTML链接调用函数,直接写javascript语句</a>
