How to remove a style added to Accept/Cancel when revisiting? #124

XiaoxingL · 2012-11-09T07:51:42Z

Hello Mottie,

For the keyboard with navigation, I can use keyboard to accept/cancel an input. But if I revisit the same input field, the style ('ui-state-hover' I guess) is still there on the accept/cancel button. So there are two buttons with 'ui-state-hover' at the same time.

How can I remove the style on accept/cancel if I am only using a keyboard?(no mouse) I tried to add $(this).find('.ui-keyboard-keyset:visible').find('.ui-state-hover').removeClass('ui-state-hover'); to beforeClose event but it did not work.

Hi onceternal!

Hmm, I'm not sure why that class would still be applied to the accept key, but the code you shared for the beforeClose callback looks like it should work. I wonder if the keyboard is already hidden by the time the callback is initialized - the script doesn't pause for that callback.

If you could provide me with a demo of this issue, it would help me figure out the issue more easily. All you'd need to do is modify this demo.

Thanks!

Edit: Oh wait, in the callback don't use $(this)... try this code instead:

beforeClose : function(e, kb, el, accepted) {
    kb.$keyboard.find('.ui-keyboard-keyset:visible').find('.ui-state-hover').removeClass('ui-state-hover');
},

It doesn't seem to work. I am willing to provide you a demo but I am so sorry that I don't know how to modify the demo on Jsfiddle. (I am pretty new)

I modified the Navigate demo on your primary demo site. I am attaching the code here. You may need to run it with the .js files under js folder, or you can modify the script resource to an online host.

I was designing an interface with direction keys and enter key ONLY, so I added

$('.ui-keyboard-input').bind('visible.keyboard', function(){
    $(this)
        .addNavigation({   
        position   : [0,0],
        toggleMode : true, 
        focusClass : 'hasFocus'
    });
})

so that everytime I reveal the input filed, the toggle Mode is on. Without these script, the toggle mode is off when revisiting. I am able to turn it on by pressing Shift F1 but I just want it be on by default. Is there any simple way to turn the navigation mode on?

The removeClass script on beforeClose did not work for me. Instead, I have to

//Manully trigger a keydown event to remove the Class applied to accept/cancel key when revisiting
var press = jQuery.Event("keydown");
press.ctrlKey = false;
press.which = 40;
$(this).trigger(press);

Following is the complete code for the demo. I am sorry for the inconvenience but that's all I know.

Thanks!!!!

Ok, I think I got it working the way you wanted - see this demo

I might need to add a beforeVisible function to the keyboard to make this a bit easier; but for now add this code:

$('.ui-keyboard-input').bind('visible.keyboard', function(e, kb) {
    kb.$keyboard.find('.ui-state-hover').removeClass('ui-state-hover');
    kb.navigation_options.toggleMode = true;
    kb.navigation_init();
});

Oh, I also ended up removing the beforeClose callback.

That works! Very simple actually. Thank you, Mottie.

In version 1.16, the hover class is now removed from all buttons when the keyboard becomes visible. So you shouldn't need any extra scripting anymore :)

I've also added a beforeVisible event.
