Sanitizers #
| Method | Description | Status |
|---|---|---|
| toString(input) | convert the input to a string. | x |
| toDate(input) | convert the input to a date, or null if the input is not a date. |
x |
| toFloat(input) | convert the input to a float, or NaN if the input is not a float. |
x |
| toInt(input [, radix]) | convert the input to an integer, or NaN if the input is not an integer. |
x |
| toBoolean(input [, strict]) | convert the input to a boolean. Everything except for '0', 'false' and '' returns true. In strict mode only '1' and 'true' return true. |
x |
| trim(input [, chars]) | trim characters (whitespace by default) from both sides of the input. | x |
| ltrim(input [, chars]) | trim characters from the left-side of the input. | x |
| rtrim(input [, chars]) | trim characters from the right-side of the input. | x |
| escape(input) | replace <, >, &, ' and " with HTML entities. |
x |
| stripLow(input [, keep_new_lines]) | remove characters with a numerical value < 32 and 127, mostly control characters. If keep_new_lines is true, newline characters are preserved (\n and \r, hex 0xA and 0xD). Unicode-safe in JavaScript. |
x |
| whitelist(input, chars) | remove characters that do not appear in the whitelist. The characters are used in a RegExp and so you will need to escape some chars, e.g. whitelist(input, '\[\]'). | x |
| blacklist(input, chars) | remove characters that appear in the blacklist. The characters are used in a RegExp and so you will need to escape some chars, e.g. blacklist(input, '\[\]'). | |
| normalizeEmail(email [, options]) | canonicalize an email address. options is an object which defaults to { lowercase: true }. With lowercase set to true, the local part of the email address is lowercased for all domains; the hostname is always lowercased and the local part of the email address is always lowercased for hosts that are known to be case-insensitive (currently only GMail). Normalization follows special rules for known providers: currently, GMail addresses have dots removed in the local part and are stripped of tags (e.g. some.one+tag@gmail.com becomes someone@gmail.com) and all @googlemail.com addresses are normalized to @gmail.com. |
