- (void)webViewDidFinishLoad:(UIWebView *)webView { NSString *js = @"function imgAutoFit() { var imgs = document.getElementsByTagName(‘img‘); for (var i = 0; i < imgs.length; ++i) { var img = imgs[i]; img.style.maxWidth = %f; } }"; js = [NSString stringWithFormat:js, [UIScreen mainScreen].bounds.size.width - 20]; [webView stringByEvaluatingJavaScriptFromString:js]; [webView stringByEvaluatingJavaScriptFromString:@"imgAutoFit()"]; }
通过JS来获取高度:document.body.offsetHeight;
