捕获＆QUOT; Enter]键。关键preSS与Android的数字输入/科尔多瓦/淘汰赛 [英] Capture "Enter" keypress with numeric input in Android/Cordova/Knockout

问题描述

我创建使用科尔多瓦/ PhoneGap的2.5.0，2.1.0淘汰赛和jQuery移动1.3.0 Android应用程序。

I am creating an Android application using Cordova/PhoneGap 2.5.0, Knockout 2.1.0 and jQuery Mobile 1.3.0.

我已经创建了一个输入，类型为数字，该输入它的价值数据绑定与淘汰赛。这也是数据绑定到一个关键的preSS事件。我打算抓住用户pressing的<大骨节病>输入键。

I have created an input with type "number", this input is databound with Knockout on it's value. It is also databound to a key press event. I'm intending to catch the user pressing the enter key.

<input type="number" data-bind="value: $root.myInputValue, event: { keypress: $root.myInputKeypress }" min="0" step="1" max="29">


self.myInputKeypress = function() {
    var keyCode = (event.which ? event.which : event.keyCode);

    alert(keyCode);

    if (keyCode === 13) {
        //Do work here

        return false;
    }

    return true;
};

当我preSS允许的密钥等一批在code运行正常和pressed键code被惊动。当我preSS <大骨节病>输入键盘没有任何反应的，看来Android是由按键认为燮pressing事件是不相关的。

When I press an allowed key such as a number the code runs as expected and the pressed keys code is alerted. When I press enter on the keyboard nothing happens, it seems that Android is suppressing events from keys it thinks are not relevant.

有没有办法来改变这种行为，这样我可以捕捉用户按<大骨节病>输入？

Is there a way to change this behaviour so that I can capture the user hitting enter?

推荐答案

我有同样的问题在模拟器，问题出在一些领域的关键code的输入是9我的设备上，这是13

I had the same issue, the problem was with number field the keycode for enter is 9 on my device, on simulator it is 13.

这对我的作品：

$('.ui-input-text').live('keyup', function(event) {
if (event.keyCode == 9) {
    // 'Go' pressed do something
}});
