My Codification is:
relation createObjectURL(entity) { instrument (framework.URL) ? framework.URL.createObjectURL(entity) : framework.webkitURL.createObjectURL(entity); }
This is my Codification for representation:
relation myUploadOnChangeFunction() { if (this.records-data.dimension) { for (var i successful this.information) { if (this.records-data.hasOwnProperty(i)) { var src = createObjectURL(this.records-data[i]); var representation = fresh Representation(); representation.src = src; imagSRC = src; $('#img').attr('src', src); } } } }
I skilled the aforesaid mistake, once I handed natural information to createObjectURL:
framework.URL.createObjectURL(information)
It has to beryllium a Blob, Record oregon MediaSource entity, not information itself. This labored for maine:
var binaryData = []; binaryData.propulsion(information); framework.URL.createObjectURL(fresh Blob(binaryData, {kind: "exertion/zip"}))
