DEVELOPING COLDFUSION 9 APPLICATIONS 35 The CFML Programming Language #FirstName# #LastName# is in Sales #FirstName# #LastName# is in Accounting #FirstName# #LastName# is in Administration #FirstName# #LastName# is not in Sales, Accounting, or Administration. cfloop and cfbreak The cfloop tag loops through the tag body zero or more times based on a condition specified by the tag attributes. The cfbreak tag exits a cfloop tag. cfloop The cfloop tag provides the following types of loops: Loop type Index Conditional Query List, file, or array Collection Description Loops through the body of the tag and increments a counter variable by a specified amount after each loop until the counter reaches a specified value. Checks a condition and runs the body of the tag if the condition is True. Loops through the body of the tag once for each row in a query. Loops through the body of the tag once for each entry in a list, each line in a file, or each item in an array. Loops through the body of the tag once for each key in a ColdFusion structure or item in a COM/DCOM object. The following example shows a simple index loop: The loop index is #LoopCount#. The following example shows a simple conditional loop. The code does the following: 1 Sets up a ten-element array with the word "kumquats" in the fourth entry. 2 Loops through the array until it encounters an array element containing "kumquats" or it reaches the end of the array. 3 Prints the value of the Boolean variable that indicates whether it found the word kumquats and the array index at which it exited the loop.
