<!--- 让coldfusion强制转换成utf-8编码格式--->
<cfprocessingdirective pageencoding="utf-8">
<!--- 用cfset标签定义局部变量--->
<cfset var1="first" />
<!--- 用cfparam标签定义局部变量--->
<cfparam name="var2" default="second" />
<!--- 输出到页面语句 --->
<cfoutput>today is tuestday!</cfoutput><br />
<cfoutput>The First Variable:#var1#</cfoutput><br />
<cfoutput>The Second Variable:#var2#</cfoutput><br />
<!--- 条件语句cfif、cfswitch--->
<!--- 条件表达1 --->
<cfif var1 eq var2>
var1 is equal to var2!<br />
<cfelse>
var1 is not equal to var2!<br />
</cfif>
<!--- 条件表达2 --->
<cfif "t" eq "tfq">
t is equal to tfq!<br />
<cfelseif "tfq" eq "tfq">
tfq is equal to tfq!<br />
<cfelse>
tfq is not equal to tfq!<br />
</cfif>
<!--- 布尔条件表达式 --->
<cfif 1 Is 1>
1=1 <br />
<cfelse>
1!=1
</cfif>
<!--- cfswitch条件词句,在此结构中要注意expression这个关键字,千万别写错了 --->
<cfset var3="tangfuqiang" />
<cfswitch expression=#var3#>
<cfcase value="tang">
tang is equal to tangfuqiang <br />
</cfcase>
<cfcase value="tangfu">
tangfu is equal to tangfuqiang!<br />
</cfcase>
<cfcase value="tangfuqiang">
tangfuqiang is equal to tangfuqiang!<br />
</cfcase>
<cfdefaultcase>
all values are not equal to tangfuqiang!<br />
</cfdefaultcase>
</cfswitch>
<!--- 循环语句 from=1 to =14与java 中i=1;i<=14 --->
<cfloop index="loopCout" from=0 to =14>
<!--- 如果索引等于0,则打印0=0且跳出循环 --->
<cfif #loopCout# Is 0>
0=0 <br />
<cfbreak>
<cfelse>
0!=0 <br />
</cfif>
the cfloop index is=<cfoutput>#loopCout#</cfoutput><br />
</cfloop>
<!--- 创建一个数组 --->
<cfset myArray=ArrayNew(1)>
<!--- 初始化myArray数组 --->
<cfset ArraySet(myArray,1,5,123)>
<!--- 给数组第四个元素设置值为tangfuqiang --->
<cfset myArray[4]="tangfuqiang">
<cfset foundit=false>
<cfset i=1>
<cfset f=0>
<!--- 打印数组长度 --->
<cfoutput>#Arraylen(myArray)#</cfoutput><br />
<!--- cfdump调试打印出数组元素, <cfabort>是让后面的不执行--->
<cfdump var="#myArray#">
<!--- 数组长度为4的值--->
<cfoutput>the first:#myArray[4]#</cfoutput><br />
<cfloop condition="(Not foundit) And (i lt Arraylen(myArray))">
<cfset f=f+0>
<!--- 访问数组与java类似--->
<cfif myArray[i] eq "tangfuqiang">
<cfset f=f+1>
<cfset foundit=true>
<cfbreak>
</cfif>
<cfoutput>#i# - #myArray[i]#<br></cfoutput>
<cfset i=i+1>
</cfloop>
<cfoutput>
i is #i#<br />
f is #f#<br />
foundit id #foundit#<br />
</cfoutput>
<!--- Set the variable CountVar to 0. --->
<cfset CountVar = 0>
<!--- Loop until CountVar = 5. --->
<cfloop condition = "CountVar LESS THAN OR EQUAL TO 5">
<cfset CountVar = CountVar + 1>
The loop index is <cfoutput>#CountVar#</cfoutput>.<br>
</cfloop>
<!--- 格式化日期字符串--->
<cfoutput>#dateformat(now()<!---,"dddd,mmmm yyyy"--->)#</cfoutput>
