  <!--- Write something  --->
  <cfscript>
    spreadsheetSetCellValue(variables.decSheetObj, 123, 56, 4);
  </cfscript>

  <!--- Write to server --->
  <cfspreadsheet action="write" filename="/report.xlsx" sheetname="Declaration" name="decSheetObj" overwrite="true" />

  <!--- Download --->
  <cfheader name="Content-Disposition" value="attachment; filename=Report_#dateFormat(now(), 'yyyymmdd ')##timeFormat(now(), 'HHmmss')#.xlsx" />

ColdFusion to js

JSStringFormat(string)

Special Characters & Quotations

写成两个就行了

<cfset mystring="We all said ""Happy birthday to you.""">
<cfset mystring2='Then we said "How old are you now?"'>
<cfoutput>
  #mystring#<br>
  #mystring2#<br>
  Here is a number sign: ##
</cfoutput>

Output:

We all said "Happy birthday to you." 
Then we said "How old are you now?" 
Here is a number sign: #

List

在 HTML 中以

<cfset local.errorRowNum="123,321,124" />

的形式出现 一开始可以使用空值, 不需要 ListNew()这样的方法来新建 List, 之后再使用 ListAppend 来添加数据

ListAppend

一定要赋值给原来的 list, 单独调用一下函数不赋值是不会有效果的.

<cfset fruitlist = ListAppend(fruitList, "kiwi") />

Query to List: ValueList

将 Query 的 Result 转换为 List

valueList(column, [delimiter])

ListLen

获取 List 的长度, 在 Loop 的时候可能会用到

ListContains

ListContains(list, substring [, delimiters, includeEmptyValues ])

##ListContains(aList, "wo")#

Description

Determines the number of elements in a list. Integer; the number of elements in a list.

Function syntax

ListLen(list[, delimiters])
ListLen(list[, delimiters, includeEmptyValues])

Parameters

• list

A list or a variable that contains one.

• delimiters

A string or a variable that contains one. Characters that separate list elements. The default value is comma. If this parameter contains more than one character, ColdFusion processes each occurrence of each character as a delimiter.

• includeEmptyValues

If includeEmptyValues is set to true, all empty values in the list will be considered when computing length. If set to false, the empty list elements are ignored.

Example

<cfset list="Partner,Response Date,Response Status" />
<cfloop from="1" to="#listLen(list)#" index="i">
  <cfoutput>
    listGetAt(list, i)
  </cfoutput>
</cfloop>

Array

在 cfscript 中以

data=[0,0,0,0,0]

的形式出现

在 HTML 中以

<!--- 这句声明可以省略 --->
<cfset local.errorRowNum=arrayNew(1) />

<cfset local.errorRowNum=[1,2,3] />

<!--- 可以不按顺序赋值，但是使用未赋值的 index 可能报错 --->
<cfset local.errorRowNum[3]=arrayNew(1) />
<cfset local.errorRowNum[4]=arrayNew(1) />
<cfset local.errorRowNum[5]=arrayNew(1) />

以及

<cfset myarray=ArrayNew(1)>
<cfset myotherarray=ArrayNew(2)>
<cfset biggerarray=ArrayNew(3)>

<cfset biggerarray[1][1][1]=myarray>
<cfset biggerarray[1][1][1][10]=3>
<cfset biggerarray[2][1][1]=myotherarray>
<cfset biggerarray[2][1][1][4][2]="five deep">

<cfset biggestarray=ArrayNew(3)>
<cfset biggestarray[3][1][1]=biggerarray>
<cfset biggestarray[3][1][1][2][3][1]="This is complex">
<cfset myarray[3]="Can you see me">

的形式出现

几个特性

• 效率比 Struct 要快

ArrayAppend

<cfset ArrayAppend(array_name, {value})>

放在 cfset 之中, 或者直接在 output 的时候用双井号调用 注意如果赋值的话就是 True or False

ListToArray

格式

listToArray("list", [delimiters])

Demo

<h1>Demo for listToArray</h1>
<cfquery name="query" datasource="CC_TEST">
  select top(3) * from ltbContact;
</cfquery>
<cfdump var="#query#" expand="false">
  <cfset xAxisLabelsdata=listToArray(ValueList(query.CONTACT_LASTNAME,'|'),'|') />
  <cfdump var="#xAxisLabelsdata#" expand="false">

Query to Array: toArray()

qSites.siteid.toArray()

---

Debug Tips

由于 ColdFusion 是服务器端进行解析的, 一般不能够分步执行

一般使用的调试方法

1. 使用 <cfabort> 来中断某段代码后方的所有代码

2. 使用 <cfdump> 来进行查看, 甚至可以查看

3. 可以直接 dump 出表单名来查看所有数据

4. 在 <cfscript> 中可以使用

WriteDump(vars)

来进行 dump

---

cfinclude & include in cfscript

用于文件引用

示例

<cfinclude template="myinclude.cfm">
<cfinclude template="……/myinclude.cfm">
<cfinclude template="/CFIDE/debug/myinclude.cfm">

<cfscript>
include "myinclude.cfm";
</cfscript>

ColdFusion Linebreak

tags: 换行, line break, coldfusion

Solution1&2

Use Chr(10) as \n There is no support for \n or \r in CF. From the Live Docs

• Chr(10) returns a linefeed character
• Chr(13) returns a carriage return character
• The two-character string Chr(13) & Chr(10) returns a Windows newline

Available if for normal string var output

<cfset someStr="This is line 1" & Chr(10) & "This is line 2" & Chr(10) & "This is line 3" />

<cfset NL=Chr(10) />
<cfset someStr="This is line 1 #NL# This is line 2#NL#This is line 3" />

Solution3

If you are into platform-independent development, you can do:

<cfset NL=CreateObject("java", "java.lang.System" ).getProperty("line.separator")>

For example, in your application.cfm/cfc or somewhere else high-level and use that.

Solution4

use

<*br*>

example:

"labelFontSize" = 7,
"labels" = ["Near Misses & Concern <*br*> Reports Logged", "First Aid Cases", "Other Recordable Cases", "Job Transfer or Restriction", "DAFW", "Fatalities"]

---

cfparam

<cfparam name="FORM.username" default="NULL"/>

使用方法

• 可以直接写对应的 CF 变量
• 可以使用表单提交过来的数据, 注意是获取表单里面对应 name 的数据
• 可以使用 type 参数设定获取过来的类型, 如果不是对应类型就会报错?
