javascript - 删除显示 HTML 字符的 elementFromPoint()

Question

我需要从 UIWebView 中选择一些文本。我引用了这个答案Getting selected elements programatically from uiwebview?但是当我使用点击它选择文本时。但它还显示所有 HTML 字符Selected Name: 1      仪器名称

-(void)singleTap:(UIGestureRecognizer *)gestureRecognizer
 {

     NSLog(@"single tap");

 CGPoint touchPoint = [gestureRecognizer locationInView:wbCont];

 //NSString *js = [NSString stringWithFormat:@"document.elementFromPoint(%f, %f).toString()", touchPoint.x, touchPoint.y];

     NSString *js = [NSString stringWithFormat:@"document.elementFromPoint(%f, %f).innerHTML", touchPoint.x, touchPoint.y];

 NSString * tagName = [wbCont stringByEvaluatingJavaScriptFromString:js];

 NSLog(@"Selected Name: %@",tagName);

 }

Answer 1

我从 stringByReplacingOccurrencesOfString: 函数得到答案。我使用了下面的代码。运行良好。

tagName=[tagName stringByReplacingOccurrencesOfString:@" " withString:@""];
