The integrity read-only property of the Request interface contains the subresource integrity value of the request.
Syntax
var myIntegrity = request.integrity;
Value
The subresource integrity value of the request (e.g., sha256-BpfBw7ivV8q2jLiT13fxDYAe2tJllusRSZ273h2nFSE=).
If an integrity has not been specified, the property returns ''.
Example
In the following snippet, we create a new request using the Request.Request() constructor (for an image file in the same directory as the script), then save the request integrity value in a variable:
var myRequest = new Request('flowers.jpg');
var myIntegrity = myRequest.integrity;
