removeAttribute Method

  • Artigo

This topic documents a feature of Binary Behaviors, which are obsolete as of Internet Explorer 10.

Removes the specified attribute from the object.

Syntax

object.removeAttribute(sAttrName)

Parameters

sAttrName Required. A String that 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 specified persistence behavior. An ID is required for the userData behavior and saveSnapshot behavior, and recommended for the saveHistory behavior and saveFavorite behavior.

This method overrides the DHTML removeAttribute method.

Example

This example uses the removeAttribute method to remove an attribute on an object participating in userData persistence.

<HEAD>

<STYLE>
   .userData {behavior:url(#default#userdata);}
</STYLE>   

<SCRIPT>
   function fnGet(){
      oPersistInput.load("oDataStore");
      oPersistInput.value=oPersistInput.getAttribute("sPersistAttr");
   }
   function fnSet(){
      oPersistInput.setAttribute("sPersistAttr",oPersistInput.value);
      oPersistInput.save("oDataStore");
   }
   function fnRem(){
      oPersistInput.removeAttribute("sPersistAttr");
      oPersistInput.save("oDataStore");
   }
</SCRIPT>
</HEAD>

<BODY >
<INPUT type=text class=userData id=oPersistInput> 
<INPUT type=button value="Get Attribute" onclick="fnGet()">
<INPUT type=button value="Set Attribute" onclick="fnSet()">
<INPUT type=button value="Remove Attribute" onclick="fnRem()">
</BODY>
