Description

https://git-wip-us.apache.org/repos/asf/cordova-ios.git branch "wkwebview"

http://trac.webkit.org/changeset/169765

Change summary:
Add -[WKWebView evaluateJavaScript:completionHandler:]

Right now it's using the private method _runJavaScriptInFrame, in a category, and returns an empty string in the completionHandler.

Hopefully this method is added in iOS 8 beta 3.

Summary:
There is no API function to do this. Yes, you can use WKUserScripts to write at before the document is loaded and after, but not at arbitrary times. You need an equivalent to [UIWebView stringByEvaluationJavascriptFromString:(NSString*)]

Steps to Reproduce:
1. Use WKWebView.
2. Try to evaluate JavaScript at an arbitrary time

Expected Results:
Ability evaluate JavaScript at an arbitrary time

Actual Results:
Not able to evaluate JavaScript at an arbitrary time

Version:
iOS 8 beta 2

Configuration:
iOS Simulator, iPad 2
