DOMaster is a lightweight Javascript library that allows for easy HTML document traversal, manipulation, event handling, and Ajax request.

Demo

Accepts CSS selectors (string), native HTML elements, and functions.

Examples:

Given the following HTML snippet:

  <div class="alphabet">
    <label>Letters</label>
      <ul class="letters">
        <li>A</li>
        <li>B</li>
        <li>C</li>
        <li>D</li>
        <li>E</li>
        <li>F</li>
        <li>G</li>
      </ul>
  </div>

1.) CSS Selectors: returns array-like object of HTML nodes

$l('ul') === DOMNodeCollection {nodes: Array[2]}

2.) HTML elements: returns array-like object of HTML nodes

  node = let node = $l('ul').nodes[0]
  $l(node) === DOMNodeCollection {nodes: Array[1]}

3.) Functions: Adds callback to DOM Content Loaded event handler if document has not yet loaded. Otherwise, calls the function immediately.

Merges the contents of two or more objects into the first objects.

  $l.extend({"a": 1, "b": 2}, {"b": 3}) === Object {a: 1, b: 3}

Performs an asynchronous HTTP (Ajax) request. Accepts an object containing settings, including a mandatory string containing the url to which the request is sent.

Setting types:

• url: String containing request url
• method: String indicating HTTP request type. Defaults to "GET".
• success: Callback triggered on 200 OK HTTP response
• error: Callback triggered on all other HTTP responses
• data: Data to be sent to the server. It is converted to query string, and in the case of GET requests, appended to the url.
• contentType: specifies the type of data sent to the server. Defaults to the application/x-www-form-urlencoded; charset=UTF-8

Example:

  $l.ajax({
    method: "POST",
    url: "someurl.php",
    success: (response) => console.log(response),
    error: (error) => console.log(error),
    data: { time: "0300", location: "New York"}
  })

If passed an argument sets the inner html of selected nodes to value. Otherwise, returns inner html value of the first selected node.

Sets the inner HTML of all selected nodes to an empty string.

Inserts content to the end of each element in the set of matched elements. Takes HTML Element, a DOMNodeCollection element, or a plain string.

If value is provided, sets the value of given attribute for all selected nodes. Else, return the value of given attribute at first selected node.

Adds given className to class list of selected nodes.

Removes given className from class list of selected nodes.

Reverses the presence of given class for selected nodes. I.e: if class is present, removes it. If absent, adds it.

Returns DOMNodeCollection of child nodes of all selected nodes. Does not return nested children.

Returns DOMNodeCollection of parent nodes of all selected nodes.

Adds given callback to given event listener for all selected nodes.

Removes all callbacks for given event listener for all selected nodes.

Returns all nested child nodes that match given selector.

Removes all selected nodes from the DOM.
