How to pass the press key to Keydown event

[Hawk]

I need to implement the following in my App page:

pre
$("#StreamUrl").keydown(function (e) {
if (e.keyCode == 32) {
$(this).val($(this).val() + "-"); // append '-' to input
return false; // return false to prevent space from being added
}
}).change(function (e) {
$(this).val(function (i, v) { return v.replace(/ /g, "-"); });
});
/pre

Basically I want to prevent the user form keying in space character.
I found that it can be down on keydown event. The above script taken from here (http://stackoverflow.com/questions/38...) is plain jQuery. In Appery, I have the keydown event, but I do not know how to pass 'e' parameter to it.

Please advise.

You don't have to pass a value for 'e', it is the event object and e.keycode will contain 32 if someone clicks . I am unsure, however, if this has relevance to a mobile device.

Thanks Terry, But I still do not know how to implement this in Appery.
If I do not pass 'e', get undefined for 'e.keyCode ==32'

You can check that e exists by a test in your javascript:

if (e) {
console.log('keydown event: ',e);
} else {
console.log('event variable does not exist');
}

Assuming e does exist you may be able the check the object contents using the console.

It appears that the e.keyCode is not available on all browsers, it is basically a microsoft thing, you may need to look for e.which also. check out this page:

I imagine the js or jquery would probably go into the load or pageshow events of your appery page

Hello,

Please use an object "event" to get all information about the event in Appery.io default events, e.g.:

preconsole.log(event.keyCode);/pre

on the keyUp event
