All Statements
STATEMENT: if...else
if
(condition) {statements1}
[else
{statements2}]
The
if...else
statement executes one set of statements if a specified condition is true, and another if it is false.
The following example tests the result of a function and displays one of two messages depending on whether the result is less than 10 or not:
Code:
if(calcaverage(x,y,z) < 10)
document.write("The average is less than 10.");
else
document.write("The average is 10 or more.");
NOTE:
You shouldn't use simple assignment statements such as
if(a = b)
in a conditional statement.
