expires Property

Sets or retrieves the expiration date of data persisted with the userData behavior.

Syntax

XML	N/A
Scripting	[ sUTCString = ] userData.expires

Possible Values

sUTCString

String that specifies or receives the expiration date in Coordinated Universal Time (UTC) format.

The property is read/write. The property has no default value.

Remarks

The expires property designates the amount of time that persisted information is available. Windows Internet Explorer removes the persisted information when the browser checks the date, and the designated time has expired.

Example

This example uses the expires property to set the expiration date of persisted data to one minute after the information is persisted.

Copy

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

<SCRIPT>
function fnSave(){
   var oTimeNow = new Date(); // Start Time
   oTimeNow.setMinutes(oTimeNow.getMinutes() + 1);
   var sExpirationDate = oTimeNow.toUTCString();

   oPersistDiv.expires = sExpirationDate;
   oPersistDiv.setAttribute("sData",oPersistText.value);
   // Save the persistence data as "sTimeout".
   oPersistDiv.save("sTimeout");
}
</SCRIPT>

:

<DIV CLASS = "userData" ID=oPersistDiv onsave = "fnSave()" >
<INPUT TYPE=text ID=oPersistText>
