ios Javascript OnClick function - ios

Question

I have loaded an HTML file from server and displayed that in UIWebview, where it contains an OnClick Function in that file, when the user OnClicks, i will get one Video URL. I want to open that video url in iOS videoplayer. how can i do this? Please help me.

Answer 1

If you have a javascript function which returns the URL when the "Get Video URL" button is clicked like this:
function getVideoURL() {
// do processing to fetch the actual video URL here
window.location = "http://www.domain.com/videos/1";
}
and button handler is set as something like this:
<a target="_blank" href="javascript:getVideoURL();" class="btn-image GetVideo"> </a>
then you will have to provide implementation for UIWebView's following delegate method in your view controller class:
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
After this you can use the relative path from the java script request
request.mainDocumentURL.relativePath
inside the delegate to refer to the URL returned from the Java script method. You can use the fetched URL to open iOS video player and play the video as follows:
MPMoviePlayerController* moviePlayer=[[MPMoviePlayerController alloc]initWithContentURL:[NSURL URLWithString: strurl]];
moviePlayer.fullscreen = YES;
[moviePlayer play];

Answer 2

You can use stringByEvaluatingJavaScriptFromString.
But we need to know what onClick function does exactly?
Does it return video URL directly?
Or it modifies HMTL to display that video URL?
If it returns videoURL directly:
NSString *videoURL = [webView stringByEvaluatingJavaScriptFromString:#"document.getElementById("yourElementID").click();"];
If it doesn't, you need to parse the HTML for videoURL after calling onClick function.
