e$getText()
e$getName()
e$getData(name)
e$getRect()

e$clear()
e$sendKeys(...)
e$moveMouseTo(xoffset = NULL, yoffset = NULL)

e$executeScript(script, ...)
e$executeScriptAsync(script, ...)

Arguments

e: An Element object.
s: A Session object.
css: Css selector to find an HTML element.
linkText: Find <a> HTML elements based on their innerText.
partialLinkText: Find <a> HTML elements based on their innerText. It uses partial matching.
xpath: Find HTML elements using XPath expressions.
name: String scalar, named of attribute, property or css key. For getData, the key of the data attribute.
xoffset: Horizontal offset for mouse movement, relative to the position of the element. If at least of of xoffset and yoffset is NULL, then they are ignored.
yoffset: Vertical offset for mouse movement, relative to the position of the element. If at least of of xoffset and yoffset is NULL, then they are ignored.
value: Value to set, a character string.
...: For sendKeys the keys to send, see key. For executeScript and executeScriptAsync argument to supply to the script.

Details

To create Element objects, you need to use the findElement (or findElement) method of a Session object.

e$findElement() finds the next HTML element from the current one. You need to specify one of the css, linkText, partialLinkText and xpath arguments. It returns a new Element object.

e$findElements() finds all matching HTML elements starting from the current element. You need to specify one of the css, linkText, partialLinkText and xpath arguments. It returns a list of newly created Element objects.

e$isSelected() returns TRUE is the element is currently selected, and FALSE otherwise.

e$getValue() returns the value of an input element, it is a shorthand for e$getAttribute("value").

e$setValue() sets the value of an input element, it is essentially equivalent to sending keys via e$sendKeys().

e$getAttribute() queries an arbitrary HTML attribute. It is does not exist, NULL is returned.

e$getClass() uses e$getAttribute to parse the ‘class’ attribute into a character vector.

e$getCssValue() queries a CSS property of an element.

e$getText() returns the innerText on an element.

e$getName() returns the tag name of an element.

e$getData() is a shorthand for querying data-* attributes.

e$getRect() returns the ‘rectangle’ of an element. It is named list with components x, y, height and width.

e$isEnabled() returns TRUE if the element is enabled, FALSE otherwise.

e$click() scrolls the element into view, and clicks the in-view centre point of it.

e$clear() scrolls the element into view, and then attempts to clear its value, checkedness or text content.

e$sendKeys() scrolls the form control element into view, and sends the provided keys to it. See key for a list of special keys that can be sent.

e$uploadFile() uploads a file to a <input type="file"> element. The filename argument can contain a single filename, or multiple filenames, for file inputs that can take multiple files.

e$moveMouseTo() moves the mouse cursor to the element, with the specified offsets. If one or both offsets are NULL, then it places the cursor on the center of the element. If the element is not on the screen, then is scrolls it into the screen first.

e$executeScript() and e$executeScriptAsync() call the method of the same name on the Session object. The first argument of the script (arguments[0]) will always hold the element object itself.
