JavaScript Operator: delete
[this page | pdf | back links]
In JavaScript,
the delete operator deletes
a property from an object. For example, suppose:
var x = {name: "ten", val: 10,
binaryval: "1010"}
This creates an object
with three name/value pairs.
Then delete x.value (or delete x["val"]) would
result in x becoming:
{name: "ten", binaryval:
"1010"}
It is usually unwise to
apply the delete operator to predefined JavaScript object properties, as
otherwise the application can crash.
