哪里＆QUOT; showkeyboard＆QUOT;从事件来吗？ [英] Where is the "showkeyboard" event coming from?

问题描述

我使用PhoneGap的，我需要赶上键盘显示事件上的Andr​​oid手机。

I am using PhoneGap and I need to catch a "keyboard is showing" event on android phones.

我发现某些线程说，用showkeyboard事件。 （这一次例如：<一href=\"http://stackoverflow.com/questions/11686368/show-hide-keyboard-is-not-working-propery-in-android-phonegap\">Show隐藏键盘不工作在Android中的PhoneGap 属性格式）

I've found some threads saying to use the "showkeyboard" event. (This one for example : Show hide keyboard is not working propery in android phonegap)

我的提问：这是与PhoneGap的可用的机器人的事件？这是一个简单的PhoneGap的事件？这是一个浏览器的事件？这是一个经典的JavaScript事件？

My question : Is this an android event usable with phonegap? Is this a simple phonegap event? Is this a browser event? Is this a classical javascript event?

我没有找到该事件的任何文档，我需要它，因为它也对方向改变射击...

I don't find any doc on this event, and I need it because it's also firing on orientation change...

编辑：我发现这一点，说从android的，但无证的：的https：/ /issues.apache.org/jira/browse/CB-6154

I've found this, saying it's from android but undocumented : https://issues.apache.org/jira/browse/CB-6154

推荐答案

这些事件是由的Andr​​oid ，但未记录即可。我遇到了一些麻烦与此，所以我不建议使用它们。

These events are from Android but are not documented. I've encountered some trouble with this so I recommend not using them.

有关的信息，以使我的工作的功能，我做了这样的事情（这只是一般的想法）：

For information, in order to make my function work, I've done something like this (this is just the general idea):

this._keyboardTimer;

document.addEventListener('showkeyboard', function (e) {
    clearTimeout(this._keyboardTimer); // keep only the last event
    this._keyboardTimer = setTimeout(function(oldOrientation){
        if (oldOrientation != getOrientation()) { 
            /* this is an orientation event */
        } else { 
            /* keyboard is really opening */
        }
    }.bind(this, getOrientation()), 200);
}.bind(this), false);

function getOrientation() {
    return ( (window.orientation == 90) || (window.orientation == -90) ) 
            ? 'landscape' 
            : 'portrait';
};

和我做的'hidekeyboard事件同样的事情。希望这会有所帮助。

And I've done the same thing with the 'hidekeyboard' event. Hope this will help.

还有一个问题（yirk之间！）：键盘可能会略微型动物。如果小键盘的变化：hidekeyboard'事件被触发....

There's another problem (yirk!): keyboards may be slightly differents. If the keyboard changes for a smaller: the 'hidekeyboard' event is fired....
