自动填充用户名和密码UIWebView Swift

我发现有很多方法可以在objective-c中自动填充用户名和密码，但我无法弄清楚如何使用Swift。 什么是Swift等效的代码，这对我想要完成的工作有用吗？ 谢谢

- (void)webViewDidFinishLoad:(UIWebView *)webView { // Auto fill the username and password text fields, assuming the HTML has //  and //  NSString *savedUsername = [[NSUserDefaults standardUserDefaults] objectForKey:@"USERNAME"]; NSString *savedPassword = [[NSUserDefaults standardUserDefaults] objectForKey:@"PASSWORD"]; if (savedUsername.length != 0 && savedPassword.length != 0) { // Create js strings NSString *loadUsernameJS = [NSString stringWithFormat:@"var inputFields = document.querySelectorAll(\"input[name='username']\"); \ for (var i = inputFields.length >>> 0; i--;) { inputFields[i].value = '%@';}", savedUsername]; NSString *loadPasswordJS = [NSString stringWithFormat:@"var inputFields = document.querySelectorAll(\"input[name='password']\"); \ for (var i = inputFields.length >>> 0; i--;) { inputFields[i].value = '%@';}", savedPassword]; // Runs the JS [self.webview stringByEvaluatingJavaScriptFromString: loadUsernameJS]; [self.webview stringByEvaluatingJavaScriptFromString: loadPasswordJS]; } 

我有这个，但由于某些原因它没有自动填充，即使我已经测试并且值正确存储并正在被正确抓取：

 func webViewDidFinishLoad(_ : UIWebView){ let savedUsername = NSUserDefaults.standardUserDefaults().stringForKey("USERNAME") let savedPassword = NSUserDefaults.standardUserDefaults().stringForKey("PASSWORD") if savedUsername == nil || savedPassword == nil {return} if ( countElements(savedUsername!) != 0 && countElements(savedPassword!) != 0) { let loadUsernameJS = "var inputFields = document.querySelectorAll(\"input[name='username']\"); \\ for (var i = inputFields.length >>> 0; i--;) { inputFields[i].value = \'\(savedUsername)\';}" let loadPasswordJS = "var inputFields = document.querySelectorAll(\"input[type='password']\"); \\ for (var i = inputFields.length >>> 0; i--;) { inputFields[i].value = \'\(savedPassword)\';}" self.webView.stringByEvaluatingJavaScriptFromString(loadUsernameJS) self.webView.stringByEvaluatingJavaScriptFromString(loadPasswordJS) } }

这是您提供的代码的简单快速转换。 SStringByEvaluatingJavaScriptFromString已经使用不同的javascript进行了测试，并且工作正常。

 func webViewDidFinishLoad(webView: UIWebView!) { let savedUsername = NSUserDefaults.standardUserDefaults().stringForKey("USERNAME") let savedPassword = NSUserDefaults.standardUserDefaults().stringForKey("PASSWORD") if savedUsername == nil || savedPassword == nil {return} if ( countElements(savedUsername!) != 0 && countElements(savedPassword!) != 0) { let loadUsernameJS = "var inputFields = document.querySelectorAll(\"input[name='username']\"); \\ for (var i = inputFields.length >>> 0; i--;) { inputFields[i].value = \'\(savedUsername)\';}" let loadPasswordJS = "var inputFields = document.querySelectorAll(\"input[name='password']\"); \\ for (var i = inputFields.length >>> 0; i--;) { inputFields[i].value = \'\(savedPassword)\';}" self.webview.stringByEvaluatingJavaScriptFromString(loadUsernameJS) self.webview.stringByEvaluatingJavaScriptFromString(loadPasswordJS) } }
