[−][src]Struct stdweb::web::html_element::OptionElement
The HTML <option>
element is used to define an item contained in a <select>
,
an <optgroup>
, or a <datalist>
element.
Methods
impl OptionElement
[src]
pub fn index(&self) -> i32
[src]
The position of the option within the list of options it belongs to, in tree-order.
If the option is not part of a list of options, like when it is part of
the <datalist>
element, the value is 0.
pub fn value(&self) -> String
[src]
Reflects the value of the value HTML attribute, if it exists;
otherwise reflects value of the Node.textContent
property.
