在使用WKWebView的時(shí)候，網(wǎng)頁調(diào)用window.open(url,"_blank”);發(fā)現(xiàn)沒有任何響應(yīng)，也沒有調(diào)用任何回調(diào)，即便寫了createWebViewWithConfiguration方法也沒用，最終找到原因是沒有設(shè)置：

PReferences.javaScriptCanOpenWindowsAutomatically = YES;
最終解決的代碼：
初始化代碼：
WKWebViewConfiguration *config = [[WKWebViewConfiguration alloc] init];    config.processPool = processPool;    WKPreferences *preferences = [WKPreferences new];    preferences.JavascriptCanOpenWindowsAutomatically = YES;//很重要，如果沒有設(shè)置這個(gè)則不會回調(diào)createWebViewWithConfiguration方法，也不會回應(yīng)window.open()方法    config.preferences = preferences;    self.webView = [[WKWebView alloc] initWithFrame:self.view.bounds configuration:config];    //    self.webView = [[WKWebView alloc] initWithFrame:self.view.bounds];    self.webView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;    self.webView.backgroundColor = [UIColor clearColor];    self.webView.contentMode = UIViewContentModeRedraw;    self.webView.opaque = YES;    [self.view addSubview:self.webView];    [_webView setUserInteractionEnabled:YES];//是否支持交互    _webView.navigationDelegate = self;    _webView.UIDelegate = self;//很重要，如果沒有設(shè)置這個(gè)則不會回調(diào)UIDelegate相關(guān)所有方法
createWebViewWithConfiguration方法代碼：在本W(wǎng)ebview打開這個(gè)網(wǎng)址
-(WKWebView *)webView:(WKWebView *)webView createWebViewWithConfiguration:(WKWebViewConfiguration *)configuration forNavigationAction:(WKNavigationAction *)navigationAction windowFeatures:(WKWindowFeatures *)windowFeatures{    NSLog(@"createWebViewWithConfiguration  request     %@",navigationAction.request);    if (!navigationAction.targetFrame.isMainFrame) {        [webView loadRequest:navigationAction.request];    }    if (navigationAction.targetFrame == nil) {        [webView loadRequest:navigationAction.request];    }    return nil;}
