Re: Making browser save userneme & password

Can you use HTML5? If so, then why not use com.google.gwt.storage.client.Storage? For example in my newer apps, if the login is successful and a checkbox is set, the app remembers the target server and username:

    // set/clear local storage

    final Storage storage = Storage.getLocalStorageIfSupported();

    if (storage != null) {

      if (view.getRememberId().getValue()) {

        storage.setItem("o_username", user);

        storage.setItem("o_server", server);

        view.getRememberId().setValue(true);

      }

      else {

        storage.setItem("o_username", "");

        storage.setItem("o_server", "");

        view.getRememberId().setValue(false);

      }

    }

The next time the user calls up the app, I check local storage for these values:

    // Fetch fields from storage.

    final Storage storage = Storage.getLocalStorageIfSupported();

    if (storage != null) {

      String user = storage.getItem("o_username");

      view.getUsername().setText(user);

      view.getServer().setText(storage.getItem("o_server"));

      if (user != null && !user.isEmpty()) {

        view.getRememberId().setValue(true);

      }

    }

I don't store the password, but I could.

This is a lot less painful than my older approach of injecting HTML (similar to yours) and it's consistent across HTML browsers, include mobile devices using MGWT.

Greetings,

I would like to have the browser save the username/password to my application.  I have searched and searched and found no solution that works on all of the standard browsers (Chrome, IE, Firefox, Safari).  Best I have been able to do (works on Firefox & IE) is:

....

<form id="login-form" action="login">

    <table>

        <tr>

            <td><button type="button">Continue as a guest</button> &nbsp;&nbsp;or &nbsp;&nbsp;Login ID:</td>

            <td> <input autocomplete="on" type="text" tabindex="0" name="username" id="username" placeholder=Email&nbsp;Address></td>

            <td>(email address)</td>

        </tr>

        <tr>

            <td align=right>Password:</td>

            <td><input autocomplete="on" type="password" tabindex="0" name="password" id="password" placeholder=Password></td>

            <td><button type="submit">Login</button></td>

        </tr>

    </table>

</form>

....

    private static final String FORM_ID = "login-form";

    private static final String USER_ID = "username";

    private static final String PASSWORD_ID = "password";

    

   private static void doLogin() {

        Window.alert("test 1");

    }

    private static native void injectLoginFunction() /*-{

        $wnd.login = function() {

            @booklion.client.login.Login::doLogin()();

        };

    }-*/;

    public void onModuleLoad() {

        injectLoginFunction();  // ok

        TextBox fUsername = TextBox.wrap(DOM.getElementById(USER_ID));

        fUsername.setStyleName("gwt-TextBox");

        PasswordTextBox fPassword = PasswordTextBox.wrap(DOM.getElementById(PASSWORD_ID));

        fPassword.setStyleName("gwt-PasswordTextBox");

        FormPanel fLoginForm = FormPanel.wrap(DOM.getElementById(FORM_ID), false); 

        fLoginForm.setAction("");  //  ok

        fLoginForm.addSubmitHandler(new FormPanel.SubmitHandler() { 

            @Override

            public void onSubmit(FormPanel.SubmitEvent event) {

                Window.alert("test 2");

            }

        });

        fLoginForm.getElement().setAttribute("onsubmit", "login();return false;");

    }

test 1 gets displayed - not test 2.  Firefox and IE offer to save the password.  Chrome and Safari do not.

Sure would appreciate some help.

Thanks.
