default

default(value, [strict=false], [ctx])

Effect

Set the return value of validate and validateSilent, when the detected value is undefined | null.

If strict mode is turned on(strict=true), set the return value when the detected value is undefined | null | ''.

Arguments

• value (*) - The default return value of validate and validateSilent. It is recommended but not necessarily to be a string. When value is a function, then set the return value of value to be the default return value. The function has a parameter: the original detected value - undefined, null or ''.

• [strict] (boolean) - Whether turn on strict mode, default is false, means no-strict mode. You can exactly set strict to true to turn on strict mode.

• [ctx] (*) - The execution context if value is a function.

Example

const schema1 = racoon.string().default('abc');
schema1.validate(undefined); // pass, return: 'abc'
schema1.validate(null); // pass, return: 'abc'
schema1.validate(''); // pass, return: ''

const schema2 = racoon().string().default('abc', true);
schema2.validate(undefined); // pass, return: 'abc'
schema2.validate(null); // pass, return: 'abc'
schema2.validate(''); // pass, return: 'abc'
