How can the SAPUI5 Cordova function navigator.camera.getPicture pass in the current context?
For example I'm passing "this" into this.onImageCapture, which is passed in as the variable "a" - fine so far...
However, when navigator.camera.getPicture is called, only imageData is displayed.
If I add any parameters to it. E.g.
<code>navigator.camera.getPicture(this.onImageSuccess(a)......
I don't get the imageData passed in.
Also, I can't attach a promise to the function as .then can't be added to navigator.camera.getPicture either.
How do I access the current context (this) AND the imageData?
<code>handleMenuItemPress: function(oEvent) {
var msg = "";
msg = oEvent.getParameter("item").getValue();
if (msg === "Camera") {
this.onImageCapture(this);
}
else if (msg === "Gallery") {
this.onImageSelect(this);
}
}
onImageCapture: function(a) {
var self = a;
navigator.camera.getPicture(this.onImageSuccess, this.onImageFail, {
//quality: 75,
quality: 10,
targetWidth: 300,
targetHeight: 300,
sourceType: navigator.camera.PictureSourceType.CAMERA,
destinationType: navigator.camera.DestinationType.FILE_URI
});
},
onImageSuccess: function(imageData) {
// can't access this
},
