attributes Collection

Retrieves a collection of attributes of the object.

What's New for Microsoft® Internet Explorer 6

This collection now applies to the attribute object.

dhtml语法

[ oObject = ] object.attributes(iIndex)

DHTML可能的值

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.

removenameditem   Removes an attribute specified with the name property from an element using the 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.

DHTML代码范例

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>
