Microsoft® JScript && Operator |
Language Reference Version 1 |
Used to perform a logical conjunction on two expressions.
result = expression1 && expression2The && operator syntax has these parts:
Part Description result Any variable. expression1 Any expression. expression2 Any expression.
If, and only if, both expressions evaluate to True, result is True. If either expression evaluates to False, result is False.For information on when a run-time error is generated by the && operator, see the Operator Behavior table.
JScript uses the following rules for converting non-Boolean values to Boolean values:
- All objects are considered true.
- Strings are considered false if and only if they are empty.
- null and undefined are considered false.
- Numbers are false if and only if they are zero.

Robotics nuts!Check out http://www.verinet.com/~dlc/ email: dlc@verinet.com... This guy ROCKS! He has made (and sells but also releases code, docs, etc...) for a number of cool little robotic modules including whiskers, IR proximity detect and remote control, Sonar proximity detect, PWM, Servo, compass. Most of these use the little PIC 12C508 controller which costs basically nothing and is soooo tiny.The 4 servos, 2400 baud serial servo controller is a wonder of magic and he sells the programmed chip for $8. Wow! |
