JS5009: Undefined identifier

  • Article

The JScript compiler does not recognize an identifier. This may occur when a referenced variable does not exist or when a with block is used to access an object property that does not exist.

To correct this error

  1. Declare the variable with a var statement (as in var x;).

  2. Make sure that only valid object members are referenced in a with block.

  3. Reference the object member explicitly instead of using the with statement.
