Using CFScript statements 129
Using conditional processing statements
CFScript includes the following conditional processing statements:
• if and else statements, which serve the same purpose as the cfif, cfelseif, and cfelse
tags
• switch, case, and default statements, which are the equivalents of the cfswitch, cfcase,
and
cfdefaultcase tags
Using if and else statements
The
if and else statements have the following syntax:
if(expr) statement [else statement]
In its simplest form, an if statement looks like this:
if(value EQ 2700)
message = "You’ve reached the maximum";
A simple if-else statement looks like the following:
if(score GT 1)
result = "positive";
else
result = "negative";
CFScript does not include an elseif statement. However, you can use an if statement
immediately after an
else statement to create the equivalent of a cfelseif tag, as the following
example shows:
if(score GT 1)
result = "positive";
else if(score EQ 0)
result = "zero";
else
result = "negative";
As with all conditional processing statements, you can use curly braces to enclose multiple
statements for each condition, as follows:
if(score GT 1) {
result = "positive";
message = "The result was positive.";
}
else {
result = "negative";
message = "The result was negative.";
}
Note: Often, you can make your code clearer by using braces even where they are not required.
