WMLScript Conditional Operator - Choosing One Expression out of Two to Evaluate Depending on a Condition

Preferences - Do not show ads

The conditional operator chooses one expression out of two to evaluate. The choice depends on whether a condition is true or false. Its format is as follows:


(condition) ? expression1 : expression2;


If condition is true, the result of expression1 will be returned. If condition is false or invalid, the result of expression2 will be returned. For example:


wmlscript_variable = (x == "WMLScript Tutorial") ? 1 : 1+2;


If the x variable contains the string "WMLScript Tutorial", the conditional operator will assign 1 to the wmlscript_variable variable, otherwise the operator will assign 3 to it.
