Object.defineProperty(ImageLoader.prototype,'preRun',
get: function(),
set: function(value)
)
preRun: LeadEvent;
PreRun is called after Run but before any configuration of the Xhr or WorkingImageElement.
The PreRun event handler is useful in situations where Run is called based on a page event, to run additional code before the request is sent.
The ImageLoaderPreRunEventArgs.Cancel property, when set to true, will cause the Fail and Always events to be invoked. This is different than the Abort method, which will fail silently and not call any callbacks.
By contrast, PreSend is a static event that is called by each ImageLoader after PreRun and after all properties (except the final HTMLImageElement.src
property for ImageLoaderUrlMode.ImageUrl, as this would send the request) are set.
Parameter | Type | Description |
---|---|---|
sender | var | The source of the event. |
e | ImageLoaderPreRunEventArgs | The event data. |
