Description
Added a simple FileReader to index.html to select an image and display it, but always errors out.
Expected:
- Click 'Choose File' button
- Select an image file
- Get 2 alerts, 1 for entering the Openfile function, and the second for entering Onload
- Image should display
Actual:
- Never gets to the Onload function, so image doesn't display
- Goes to onError
I have traced through the native side in CordovaActivity and CordovaChromeClient and it seems to get the result URL fine, but when it returns to the javascript side, the result ends up being null. I'm not too familiar with how the bridging works, so maybe there is some type of disconnect there.
In the log, I am using the Cordova File plugin, but the issue still occurs even if I am not using the plugin. Everything is the same with or without the plugin, native side gets the result, but javascript side gets null.
<input type='file' accept='image/*' onchange='openFile(event)'><br> <img id='output'> <script> var openFile = function(event) { alert("Inside Openfile Function"); var input = event.target; var reader = new FileReader(); reader.onload = function(){ alert("Inside Onload Function"); var dataURL = reader.result; var output = document.getElementById('output'); output.src = dataURL; }; reader.onerror = function() { console.log('An error occurred while reading a file.'); console.log(reader.error); }; reader.readAsDataURL(input.files[0]); }; </script>
