Question

我的项目中有以下RN代码。我想导航到我发表评论的屏幕。我在一个Web视图中，如果条件为true，我想导航到特定屏幕。我有什么办法可以做到这一点？

const int num = 2;
int arr[num];
arr[0] = 123;
arr[1] = 456;

vector<int*> inner;
vector<int**> outer;

inner.reserve(num);
outer.reserve(num);

for(int i = 0; i < num; ++i)
{
    inner.push_back(&arr[i]);
    outer.push_back(&inner[i]);
}

cout << "before:";
for (int i : arr) {
    cout << i << " ";
}
cout << endl;

for(int i = 0; i < num; ++i) {
    **(outer[i]) *= 2;
}

cout << "after:";
for (int i : arr) {
    cout << i << " ";
}
cout << endl;

class CitizenLoginWebView extends Component {
  render() {
    return (
        <WebView
            ref={'webview'}
            source={{uri: citizenLoginUrl}}
            onNavigationStateChange={navState => {
                if (navState.title === "Consent Platform") {
                    if (hasWordsInString(navState.url, searchWords)) {
                        this.refs.webview.stopLoading();
                        this.props.navigation.navigate(screen);
                        console.log('Words found');
                    }
                }
            }}
        />
    );
  }
}

如果您使用React-Navigation，这将起作用
