Question

it can work in ios10 or before , but it can not work in ios11?

- (void)jumpToHash:(WKWebView *)wkWebView {
NSString * jsJumpToHash =[NSString stringWithFormat:@"function jumpToHash(){window.location.hash ='#%@hash';};",self.hashLocation];

[wkWebView evaluateJavaScript:jsJumpToHash completionHandler:^(id Result, NSError * error) {}];

NSString *jsFun = @"jumpToHash()";

[wkWebView evaluateJavaScript:jsFun completionHandler:^(id Result, NSError * error) {}];

self.hashLocation = @"";
}

Answer 1

In iOS11, window.location.hash doesn't have support to scroll to location.

Please use following code for scroll web page to selected location

[self.webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"var hashElement=document.getElementById('%@');if(hashElement) {hashElement.scrollIntoView();}", href]];
