in thread Can't Find Form with WWW::Mechanize::Chrome

Sorry I ask another stupid question on this node. As your help, I can find the form But it still can't submit and login! Actually, I can see the chrome open, username&password input but no login
use WWW::Mechanize::Chrome; Log::Log4perl->easy_init($ERROR); # Set priority of root logger to ER +ROR my $mech = WWW::Mechanize::Chrome->new(); $mech->get('http://10.86.11.200:8090/'); $mech->form_number(1); $mech->field('#username', 'admin'); $mech->field('#password', '*******'); $mech->click_button(id => 'loginBtn'); sleep 10;
Is there any other mistake I don't notice? Please Help

    $mech->click_button(id => 'loginBtn');

    The above should work, but you can check whether the correct element is used by inspecting it:

    my $btn = $mech->xpath('//*[@id="loginBtn"]', single => 1 ); print $btn->get_attribute('outerHTML'); $mech->click( $btn );

      The above should work, but you can check whether the correct element is used by inspecting it:

      Thanks your help, it can find the correct element, but it doesn't login by the script. I notice that when if I comment the lines about click, I can see the input content(admin, **** ) on the chrome, but when I submit thru the $mech->click_button(id => 'loginBtn'), the contents in the form will disappear!. that's why I can't login I think.

      Sorry for my poor HTML knowledge, I can't understand what happen behind this situation. Please help!

        Without seeing the Javascript and the complete page, I can only guess and suggest to use the heavy mallet instead:

        Maybe the form fields are just there for show and the Javascript on the page copies the contents of the form fields as they are entered into some JS variables.

        One approach would be to make WWW::Mechanize::Chrome send the appropriate control events in the hope that the Javascript picks them up:

        my @pre_events = (qw(focus)); my @post_events = (qw(blur)); $mech->field('#username', 'admin', undef, \@pre_events, \@post_events) +; $mech->field('#password', '*******', undef, \@pre_events, \@post_event +s); $mech->click_button(id => 'loginBtn');

        Another possible approach then would be to use the ->sendkeys to "enter" the data into the form fields:

        $mech->eval('document.getElementById("username").focus()'); $mech->sendkey(string => 'admin'); $mech->eval('document.getElementById("password").focus()'); $mech->sendkeys(string => '*******'); $mech->click_button(id => 'loginBtn');

    $mech->click_button(id => 'loginBtn');

    Untested, should the id be prefixed with #? 'A selector prefixed with '#' must match the id attribute of the input'.

    $mech->click_button(id => '#loginBtn');
