attributes Collection

Internet Development Index

---

Retrieves a collection of attributes of the object.

Syntax

[ oColl = ] object.attributes

[ oObject = ] object.attributes(iIndex)

Possible Values

oColl	Zero-based array of attributes applied to the object.
oObject	Reference to an individual item in the array of elements contained by the object.
iIndex	Required. Integer that specifies the zero-based index of the item to be returned.

Members Table

The following table lists the members exposed by the attributes object. Click a tab on the left to choose the type of member you want to view.

Attributes/Properties

Property	Description
length	Sets or retrieves the number of objects in a collection.

Methods

Method	Description
getNamedItem	Retrieves an attribute specified with the name property using the attributes collection.
item	Retrieves an attribute for an element from the attributes collection.
removeNamedItem	Removes an attribute specified with the name property from an element using the attributes collection.
setNamedItem	Adds an attribute to an element using an attributes collection.

Remarks

The expando properties of an object are included in the attributes collection of the object as of Internet Explorer 6. To access the expando properties of an object in earlier versions of Internet Explorer, use the Microsoft JScript®?B>for...in construct.

The attributes collection does not expose the style object. Use the cssText property of the object's style property to retrieve the persistent representation of the cascading styles associated with an object.

Unlike other DHTML collections, such as all and children, the attributes collection is static. Modifications to the properties of an object are not automatically reflected by an existing reference to the attributes collection of that object.

Example

This example shows how to iterate through the collection of attributes of the specified object, displaying the name and value of the attributes as well as the language of the attribute (HTML or script).

<SCRIPT>
function ShowAttribs(oElem)
{
txtAttribs.innerHTML = '';
// Retrieve the collection of attributes for the specified object.
var oAttribs = oElem.attributes;
// Iterate through the collection.
for (var i = 0; i < oAttribs.length; i++)
{
var oAttrib = oAttribs[i];
// Print the name and value of the attribute.
// Additionally print whether or not the attribute was specified
// in HTML or script.
txtAttribs.innerHTML += oAttrib.nodeName + '=' +
oAttrib.nodeValue + ' (' + oAttrib.specified + ')<BR>';
}
}
</SCRIPT>
