setAttribute Method

Sets the value of the specified attribute.

dhtml语法

object.setAttribute(sAttrName, vAttrValue)

Parameters

sAttrName Required. Stringthat specifies the name of the persistent attribute.
vAttrValue Required. Variant that specifies the value of the persistent attribute.

Return Value

No return value.

Remarks

If the specified attribute is not already present, the setattribute method adds the attribute to the object and sets the value.
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 setattribute method.

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()">
