Sets or retrieves the expiration date of data persisted with the userData behavior.
Syntax
HTML N/A Scripting oPersistObject.expires [ = sUTCString ]
Possible Values
sUTCString String that specifies the expiration date in UTC (Universal Time Coordinate) format. The property is read/write with no default value.
Remarks
The expires property designates the amount of time that persisted information is available. Microsoft® 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.
Sample Code
<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>
