msCachingEnabled - Web APIs 编辑

Non-standard

This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The msCachingEnabled method gets the current caching state for an XMLHttpRequest.

This proprietary method is specific to Internet Explorer and Microsoft Edge.

Syntax

 var cacheState = XMLHttpRequest.msCachingEnabled();

Parameters

cacheState[out, retval]

Type = boolean. If true, XMLHttpRequestis cached to disk. If false, it is not written to disk.

Return value

Type: boolean. If true, XMLHttpRequestis cached to disk. If false, it is not written to disk.
