Looping over a list steps through elements contained in any of these entities:
<cfloop
index = "index_name"
list = "list_items"
delimiters = "item_delimiter">
...
</cfloop>
cfabort, cfbreak, cfexecute, cfexit, cfif, cflocation, cfswitch, cfthrow, cftry
| Attribute | Req/Opt | Default | Description |
|---|---|---|---|
index |
Required |
|
In a list loop, the variable to receive next list element. |
list |
Required |
|
A list, variable, or filename; contains a list |
delimiters |
Optional |
|
Character(s) that separates items in list |
This loop displays four names:
<cfloop index = "ListElement"
list = "John,Paul,George,Ringo">
<cfoutput>#ListElement#</cfoutput><br>
</cfloop>
You can put more than one character in the delimiters attribute, in any order. For example, this loop processes commas, colons, and slashes as list delimiters:
<cfloop index = "ListElement"
list = "John/Paul,George::Ringo"
delimiters = ",:/">
<cfoutput>#ListElement#</cfoutput><br>
</cfloop>
ColdFusion skips the second and subsequent consecutive delimiters between list elements. Thus, in the example, the two colons between "George" and "Ringo" are processed as one delimiter.
To loop over each line of a file, use the tag this way:
<cfloop list="#theFile#" index="curLine" delimiters="#chr(10)##chr(13)#"> ... </cfloop>
