Microsoft® JScript ?: Operator |
Language Reference Version 1 |
Executes one of two statements depending on a condition.
test ? statement1 : statement2The ?: operator syntax has these parts:
Part Description test Any Boolean expression. statement1 A statement executed if test is true. May be a compound statement. statement2 A statement executed if test is false. May be a compound statement.
The ?: operator is a shortcut for an if...else statement. It is typically used as part of a larger expression where an if...else statement would be awkward. For example:The example creates a string containing "Good evening." if it is after 6pm. The equivalent code using an if...else statement would look as follows:var now = new Date(); greeting = "Good" + (now.getHours() > 17) ? " evening." : " day.";var now = new Date(); greeting = "Good"; if (now.getHours() > 17) greeting += " evening."; else greeting += " day.";
