第九章 使用字符串
1.使用字符串对象
<script>
mystring="gdgdfgfddddaaaaaaaaaaaabbbbbbbbbbbbbbbbbvbhg.
"
document.write(mystring)
document.write(mystring.bold())
document.write(mystring.toUpperCase())
</script>
2.使用子字符串
<script>
str1="fdsf 1111 gfdgfd dfdsf cccc dddd.
"
document.write(str1)
document.write(str1.substring(0,13)+"
")
document.write(str1.substr (20,11)+"
")
</script>
3.连接字符串
<script>
str1="may you find"
str2="peace,happiness and prosperity.
"
document.write(str1+"
")
document.write(str2)
document.write(str1.concat(str2))
document.write(str1+=str2)
</script>
4.格式化字符串变量
<script>
str1="peace,happiness and prosperity.
"
document.write(str1)
document.write(str1.big())
document.write(str1.small())
document.write(str1.bold())
document.write(str1.italics())
document.write(str1.strike())
document.write(str1.fontsize(6))
document.write(str1.fontcolor(green))
</script>
5.创建锚和链接
<script>
str1="this is the bigginning of the page.
"
str2="….
"
str3="this is the end of the page .
"
str4="link to the start
"
str5="link to the end
"
document.write(str1.anchor("start"))
for(i=0;i<10;i++)
document.write(str2);
document.write(str3.anchor("end"))
document.write(str4.link("#start"))
document.write(str5.link("#end"))
</script>
6.确定字符串长度
<script>
str1="this is the bigginning of the page."
document.write(str1+"
")
document.write( "字符串的长度是:"+str1.length)
document.write("字符串全部大写是;"+str1.toUpperCase())
document.write("字符串全部小写是;"+str1.toLowerCase())
</script>
7.在字符串内搜索
<script>
str1="this is the end of the line.
"
document.write(str1)
document.write("字符end在字符串的位置是"+str1.search("end"))
document.write("字符dog在字符串的位置是"+str1.search("dog"))
</script>
8.定位字符串中的字符
<script>
str1="spring is a time for flowers and trees and baby bunnles
"
document.write(str1)
document.write("the index for the second word ‘and' is"+str1.indexOf("and",30))
documednt.write("the last index of the word ‘and' is "+str1.lastIndexOf("and"))
</script>
9.替换字符串中的文本
<script>
str1="spring is a time for flowers and trees and baby bunnles
"
document.write(str1)
document .write(str1.replace("and",","))
</script>
10.字符串分离
<script>
str1="spring is a time for flowers and trees and baby bunnles
"
document.write(str1)
str1array=str1.split(" ")
document.write(str1array[0]+"
")
document.write(str1array[1]+"
")
document.write(str1array[2]+"
")
document.write(str1array[3]+"
")
</script>
第十章 使用日期和时间
1.使用Date对象
<script>
cdate=new Date("august 2,1989 12:30:00")
document.write(cdate)
</script>
2.显示当地时间和日期
<script>
cdate=new Date()
document.write("当前时间是:"+cdate.toGMTString()+"
")
document.write("日期和时间是:"+cdate.toLocaleString())
</script>
3.获得时间和日期值
<script>
cdate=new Date()
document.write("显示当前的星期"+cdate.getDay()+"
")
document.write("显示当前的月份"+cdate.getMonth()+"
")
document.write("显示当前的日期"+cdate.getDay()+"
")
document.write("显示当前的年份"+cdate.getYear()+"
")
document.write("显示当前的小时"+cdate.getHours()+"
")
document.write("显示当前的分钟"+cdate.getMinutes()+"
")
document.write("显示当前的秒"+cdate.getSeconds()+"
")
</script>
4.设置时间和日期值
<script language=javascript>
cdate=new Date("December 25,1984")
document.write("显示日期"+cdate+"
")
document.write("设置月份"+cdate.setMonth(10)+"
")
document.write("设置日期"+cdate.setDate(23)+"
")
document.write("设置年份"+cdate.setYear(2000)+"
")
document.write("设置小时"+cdate.setHours(13)+"
");
document.write("设置分钟"+cdate.setMinutes(47)+"
");
document.write("设置秒"+cdate.setSeconds(23)+"
");
document.write("显示设置后的日期和时间"+cdate);
</script>
