Document.getElementsByName()
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since январь 2018 г..
Метод getElementsByName() объекта Document возвращает коллекцию NodeList элементов с заданным name.
Синтаксис
var elements = document.getElementsByName(name);
- elements — это живая
NodeListколлекция. То есть, она автоматически обновляется, когда элементы с таким жеnameдобавляются/удаляются из документа. - _name _— это значение поля
nameэлемента(элементов).
Пример
<!doctype html>
<html lang="en">
<title>Example: using document.getElementsByName</title>
<input type="hidden" name="up" />
<input type="hidden" name="down" />
<script>
var up_names = document.getElementsByName("up");
console.log(up_names[0].tagName); // displays "INPUT"
</script>
</html>
Notes
The name attribute can only be applied in (X)HTML documents.
The returned NodeList Collection contains all elements with the given name, such as <meta>, <object>, and even elements which do not support the name attribute at all.
Предупреждение:
The getElementsByName method works differently in IE10 and below. There, getElementsByName() also returns elements that have an id attribute with the specified value. Be careful not to use the same string as both a name and an id.
Предупреждение:
The getElementsByName method works differently in IE. There, getElementsByName() does not return all elements which may not have a name attribute (such as <span>).
Предупреждение:
Both IE and Edge return an HTMLCollection, not a NodeList
