jQuery-使用navigator.notification.alert [英] JQuery - Using navigator.notification.alert

问题描述

我要求弹出窗口带有自定义标题(让它从应用程序中的index.html看起来很俗气).

I have a requirement for a popup to appear with a custom heading (having it appear from index.html on an app just looks tacky).

我尝试了以下链接末尾的建议:

I tried the suggestion at the end of the following link:

使用PhoneGap HTML在iOS中自定义JavaScript警报

因此，我在脚本部分的index.html中添加了以下代码:

So I added the code below to my index.html in the script section:

   function showMessage(message, callback, title, buttonName){

        title = title || "default title";
        buttonName = buttonName || 'OK';

        if(navigator.notification && navigator.notification.alert){

            navigator.notification.alert(
                message,    // message
                callback,   // callback
                title,      // title
                buttonName  // buttonName
            );

        }else{

            alert(message);
            callback();
        }

    }

更新

我有以下警报代码；

if ((inputNumber>maxAllowed))
        {
        showMessage("The input is too high.",null,"Warning","Warning");
        }

编译应用程序后，此方法不起作用.

After compiling the app, this is not working.

以下是在index.html中:

The following is in index.html:

    document.addEventListener("deviceready", onDeviceReady, false);

            function onDeviceReady() {
            // Now safe to use the PhoneGap API
            }

<function shown above is here>

有人知道为什么这仍然行不通吗?从index.html显示

Any idea why this is still not working? Showing from index.html

谢谢.

亲切的问候，

推荐答案

此错误告诉您 navigator.notification 函数不存在.

This error tells you that function navigator.notification don't exist.

通常这是因为:

1. Phonegap/Cordova未在HEAD内初始化

2. 函数未在deviceready事件中初始化.基本上，在cordova.js完全初始化之前无法调用函数.

1. Phonegap/Cordova is not initialized inside a HEAD

2. Function is not initialized inside a deviceready event. Basically function can't be called before cordova.js is fully initialized.

document.addEventListener("deviceready", onDeviceReady, false);

function onDeviceReady() {
    // Now safe to use the PhoneGap API
}
