名称 gets or sets the 名称 property of an element in the DOM. It only applies to the following elements: <a> , <applet> , <button> , <form> , <frame> , <iframe> , <img> , <input> , <map> , <meta> , <object> , <param> , <select> ，和 <textarea> .

注意： 名称 property doesn't exist for other elements; unlike tagName and nodeName , it is not a property of the 节点 , 元素 or HTMLElement 接口。

名称 can be used in the document.getElementsByName() method, a form and with the form 元素 collection. When used with a form or elements collection, it may return a single element or a collection.

句法

HTMLElement.name = string
let elName = HTMLElement.name
let fControl = HTMLFormElement.elementName
let controlCollection = HTMLFormElement.elements.elementName

范例

<form action="" name="formA">
  <input type="text" value="foo">
</form>
<script type="text/javascript">
  // Get a reference to the first element in the form
  let formElement = document.forms['formA'].elements[0]
  // Give it a name
  formElement.name = 'inputA'
  // Show the value of the input
  alert(document.forms['formA'].elements['inputA'].value)
</script>

In Internet Explorer (IE), the 名称 property of DOM objects created using document.createElement() can't be set or modified.
