    if (![navigationAction.request.URL.absoluteString containsString:@"http://"] && ![navigationAction.request.URL.absoluteString containsString:@"https://"]) {
       
        }
        decisionHandler(WKNavigationActionPolicyCancel);
    } else  {

WKWebViewConfiguration *config = [WKWebViewConfiguration new];
 self.userContent = [[WKUserContentController alloc] init];
 [self.userContent addScriptMessageHandler:self name:@"JSFuncName"];
 config.userContentController = self.userContent;
 WKWebView *webv = [[WKWebView alloc] initWithFrame:CGRectZero configuration:config];

-(void)userContentController:(WKUserContentController *)userContentController didReceiveScriptMessage:(WKScriptMessage *)message
{
    NSString *scriptName = message.name;
    NSLog(@"%@", message.body);
    if([scriptName isEqualToString:@"JSFuncName"]){
    	NSLog(@"To Do Something");
    }
