objective-c - WebView加载html时，不能响应模态窗口

问题描述

RT，在OSX下的WebView中（非iOS）,加载html网页时，window.showModalDialog这句js无效，无法弹窗，在Safari中加载同样网页时有响应，请问有大神做过类似的问题么？代码如下:

- (WebView *)webView:(WebView *)sender createWebViewWithRequest:(NSURLRequest *)request{NSWindow *window = [[NSWindow alloc] initWithContentRect:NSMakeRect(0, 0, 400, 300) styleMask:NSTitledWindowMask | NSClosableWindowMask | NSMiniaturizableWindowMask | NSResizableWindowMask backing:NSBackingStoreBuffered defer:YES]; [window setCollectionBehavior:NSWindowCollectionBehaviorFullScreenPrimary]; WebView *webView = [[WebView alloc] init]; [webView setFrameLoadDelegate:self]; window.contentView = webView; [webView.mainFrame loadRequest:request]; [window makeKeyAndOrderFront:self]; return webView; }- (WebView *)webView:(WebView *)sender createWebViewModalDialogWithRequest:(NSURLRequest *)request{ return [self webView:sender createWebViewWithRequest:request];}- (void)webViewRunModal:(WebView *)sender{ [sender.window makeKeyAndOrderFront:self]; }- (void)webViewShow:(WebView *)sender{[sender.window makeKeyAndOrderFront:self]; }- (void)webViewClose:(WebView *)sender{ [sender.window close]; }

问题解答

最好不要用showModalDialog，换成p比较好，osx的webview我没用过，但是以前做android开发的时候，webview是不支持模态窗口的弹出的，换成p才行，不知道osx的webview不弹出是不是这个原因

调试了很久终于解决了，提供一下代码给后来人一个思路。

#pragma -mark -WebView Delegate - (WebView *)webView:(WebView *)sender createWebViewWithRequest:(NSURLRequest *)request{ NSUInteger windowStyleMask = NSClosableWindowMask|NSMiniaturizableWindowMask|NSTitledWindowMask; _webWindow = [[NSWindow alloc] initWithContentRect:NSMakeRect(0, 0, 400, 300) styleMask:windowStyleMask backing:NSBackingStoreNonretained defer:YES]; [_webWindow setReleasedWhenClosed:NO]; WebView* newWebView = [[WebView alloc] initWithFrame:[_webWindow contentRectForFrameRect:_webWindow.frame]]; [newWebView setAutoresizingMask:NSViewWidthSizable|NSViewHeightSizable]; [[newWebView mainFrame] loadRequest:request]; [_webWindow setContentView:newWebView]; [_webWindow center]; [_webWindow makeKeyAndOrderFront:nil]; return newWebView; } - (WebView *)webView:(WebView *)sender createWebViewModalDialogWithRequest:(NSURLRequest *)request{ return [self webView:sender createWebViewWithRequest:request]; } - (void)webViewRunModal:(WebView *)sender{ [sender.window makeKeyAndOrderFront:self]; } - (void)webViewShow:(WebView *)sender{ [sender.window makeKeyAndOrderFront:self]; } - (void)webViewClose:(WebView *)sender{ [sender.window close]; }
