Question

I am loading an html file to uiWebView and getting variables that were set previously on a div using:

 NSString *body = [self.webView stringByEvaluatingJavaScriptFromString:
                          @"document.getElementById('var').innerHTML"];

but I need now the reverse process, set variable to html file using javascript. Html javascript code will wait then until I send a var. Something like following pseudo code,

 [self.webView stringSetJavaScriptFromString:
           @"document.setElementById('var').innerHTML", myStringVar];

Thank you.

Have you already tried

[self.webView stringByEvaluatingJavaScriptFromString:
      [NSString stringWithFormat:@"document.getElementById('var').innerHTML = '%@';",myStringVar]];

?
