UIWebView Swift username and password auto-complete

Question

I have found many ways to autofill username and password in objective-c, but I cannot figure out how to make it work with Swift. What would the Swift equivalent of this code be and would it work for what I'm trying to execute? Thanks

- (void)webViewDidFinishLoad:(UIWebView *)webView { // Auto fill the username and password text fields, assuming the HTML has // <input type="text" name="username"> and // <input type="text" name="password"> 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]; } 

I have this, but it doesn’t autocomplete for some reason, although I checked, and the values ​​are stored correctly and grabbed correctly:

 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) } }

Here is a simple quick conversion of your provided code. SStringByEvaluatingJavaScriptFromString has been tested using different javascript and is working correctly.

 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) } }
