  • Article

Event handler provided to indicate that previously cached resources have been updated.

 

Syntax

Event Property object.onupdateready = handler;
addEventListener Method object.addEventListener("updateready", handler, useCapture)

 

Event handler parameters

  • handler [in]
    Type: Function

    Event handler

Remarks

If this event indicates that the resources have been redownloaded, the script can use IHTMLApplicationCache::swapCache to switch to the new cache.

If there is more than one event, the updateready event will be the last one in the sequence.

Alternatively, you could use an anonymous delegate function such as

object.onupdateready = function (e) { … }

where e is the cached event.
