removeAttribute Method

Removes the specified attribute from the object.

dhtml语法

object.removeAttribute(sAttrName)

Parameters

sAttrName Required. Stringthat specifies the name of the persistent attribute.

Return Value

No return value.

Remarks

The sAttrName value is not case sensitive.
This method requires an object participating in persistence, where that object has a class name equal to the desired persistence behavior. An id is required for the userdata and savesnapshot behaviors, and recommended for the savehistory and savefavorite behaviors.
this method overrides the dhtml removeattribute method.
