Quick Reference
This is a quick reference list of JavaScript DOMTokenList methods and properties with examples of how they are used.
- JavaScript – DOMTokenList add() MethodThe DOMTokenList add() method adds one or more tokens to a DOMTokenList, which is a set of space-separated tokens that can be accessed by index.
- JavaScript – DOMTokenList contains() MethodThe DOMTokenList contains() method returns “true” if a DOMTokenList contains a class. If not, it will return “false”.
- JavaScript – DOMTokenList entries() MethodThe DOMTokenList entries() method returns an iterator with the key/value pairs from a DOMTokenList.
- JavaScript – DOMTokenList forEach() MethodThe DOMTokenList forEach() method executes a callback function for each token in a DOMTokenList.
- JavaScript – DOMTokenList item() MethodThe DOMTokenList item() method returns the token at a specified index in a DOMTokenList.
- JavaScript – DOMTokenList keys() MethodThe DOMTokenList keys() method returns an iterator with the keys from a DOMTokenList.
- JavaScript – DOMTokenList length PropertyThe DOMTokenList length property returns the number of tokens in a DOMTokenList.
- JavaScript – DOMTokenList remove() MethodThe DOMTokenList remove() method removes tokens from the DOMTokenList, which is a set of space separated tokens that can be accessed by index.
- JavaScript – DOMTokenList replace() MethodThe DOMTokenList replace() method replaces a token in a DOMTokenList, which is a set of space separated tokens that can be accessed by index.
- JavaScript – DOMTokenList supports() MethodThe DOMTokenList supports() method returns “true” if a token in a DOMTokenList is one of the attribute’s supported tokens.
- JavaScript – DOMTokenList toggle() MethodThe DOMTokenList toggle() method toggles a token in a DOMTokenList on or off.
- JavaScript – DOMTokenList value PropertyThe DOMTokenList value property returns a DOMTokenList as a string
- JavaScript – DOMTokenList values() MethodThe DOMTokenList values() method returns an iterator with the keys from a DOMTokenList.
JavaScript Notes:
- When using JavaScript, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- JavaScript is a case-sensitive language; firstName is NOT the same as firstname
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
- JavaScript variables must begin with a letter, $, or _
- JavaScript variables are case sensitive (x is not the same as X)
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
