The Element.attributes
property returns a live collection of all attribute nodes registered to the specified node. It is a NamedNodeMap
, not an Array
, so it has no Array
methods and the Attr
nodes' indexes may differ among browsers. To be more specific, attributes
is a key/value pair of strings that represents any information regarding that attribute.
Syntax
var attr = element.attributes;
Example
Basic examples
// Get the first <p> element in the document var para = document.getElementsByTagName("p")[0]; var atts = para.attributes;
Enumerating elements attributes
Numerical indexing is useful for going through all of an element's attributes.
The following example runs through the attribute nodes for the element in the document with id "paragraph", and prints each attribute's value.
<!DOCTYPE html> <html> <head> <title>Attributes example</title> <script type="text/javascript"> function listAttributes() { var paragraph = document.getElementById("paragraph"); var result = document.getElementById("result"); // First, let's verify that the paragraph has some attributes if (paragraph.hasAttributes()) { var attrs = paragraph.attributes; var output = ""; for(var i = attrs.length - 1; i >= 0; i--) { output += attrs[i].name + "->" + attrs[i].value; } result.value = output; } else { result.value = "No attributes to show"; } } </script> </head> <body> <p id="paragraph" style="color: green;">Sample Paragraph</p> <form action=""> <p> <input type="button" value="Show first attribute name and value" onclick="listAttributes();"> <input id="result" type="text" value=""> </p> </form> </body> </html>
