URL: https://github.com/apache/cordova-plugin-wkwebview-engine/issues/187
I have a HTML file which contains local resource files such as css, js files
inside its content. These local resource files are in zip format. My app uses
Cordova's WKWebView to display this html file on wkwebview. I m trying to
upload an image in one of the html image element on WKWebView which is saved
locally and is converted to base64 string but its not updating the image. I
have a html image tag in local html like this.
`<img id='image' style='display: block; height: 100%; width:100%; margin:0
auto;' />
`
I update the image using evaluateJavascript method of WkWebView like below
```
NSData *imageData = UIImagePNGRepresentation(image);
NSString *base64Str = [imageData base64EncodedStringWithOptions:0];
NSString *js = [NSString
stringWithFormat:@"document.getElementById('image-id').src='data:image/png;base64,%@'",base64Str];
[self.wkWebView evaluateJavaScript:js completionHandler:nil];
```
This is suppose to add the image on the image tag element but it does
nothing. I tried this in normal WKWebView and it updates the image without any
problem.
This in iOS, Objective C code. We are seeing this issue in all apple
devices.
I am using Cordova version 5.0.0
