[英]Phonegap: local notification repeat every Sunday of the week?
I'm trying to implement the Phonegap local notification in my project. 我正在尝试在我的项目中实现Phonegap本地通知。
I'm using this plugin: 我正在使用这个插件:
de.appplant.cordova.plugin.local-notification-custom
I have installed the plugin and tested it and it works fine. 我已经安装了插件并对其进行了测试,并且工作正常。
I tested it with this code and it works fine: 我使用此代码测试它,它工作正常:
cordova.plugins.notification.local.schedule({
id : 1,
title : 'I will bother you every minute',
text : '.. until you cancel all notifications',
sound : null,
every : 'minute',
autoClear : false,
at : new Date(new Date().getTime() + 10*1000)
});
The above notification will run every minute and work fine. 以上通知将每分钟运行并且正常工作。
Now, I need to set a local notification that will only run on every Sunday
and every week
. 现在,我需要设置一个仅在每个
Sunday
和week
运行的本地通知。
I came across something like this but when tested it, it does nothing: 我遇到过这样的事情但是在测试它时它什么也没做:
cordova.plugins.notification.local.schedule({
id: 1,
title: "Test...",
text: "Test...",
sound: null,
every: 'week',
at: sunday_16_pm
});
I don't even know if at: sunday_16_pm
is correct or not! 我甚至不知道是否
at: sunday_16_pm
是否正确!
Could someone please advice on this issue? 有人可以就这个问题提出建议吗?
Thanks in advance. 提前致谢。
EDIT: 编辑:
After searching for hours and finding nothing, I just came across this documentation: 搜索了几个小时后什么都没发现,我刚看到这个文档:
https://github.com/katzer/cordova-plugin-local-notifications/wiki/04.-Scheduling https://github.com/katzer/cordova-plugin-local-notifications/wiki/04.-Scheduling
They have a sample code that says: 他们有一个示例代码说:
Schedule Repeatedly 重复安排
cordova.plugins.notification.local.schedule({
text: "Delayed Notification",
firstAt: monday,
every: "day",
icon: "file://img/logo.png"
}, callback);
But what is monday
?!? 但
monday
是什么?!? is that a variable? 那是一个变量吗? And if so, how do you create that variable?
如果是这样,你如何创建该变量?
I don't understand why people write documentation as if no one else would want to read/understand them!! 我不明白为什么人们写文档就好像没有人想要阅读/理解它们一样!
Another edit: 另一个编辑:
I found this which explains exactly what i'm trying to do but I'm not using ionic and never have. 我发现这可以解释我正在尝试做什么,但我没有使用离子,从来没有。 So I don't understand the code that is provided there at all!
所以我根本不理解那里提供的代码!

I don't know about those variables sunday_16_pm
or monday
either, but you can use your own variable with firstAt
. 我不知道那些变量
sunday_16_pm
或monday
,但你可以使用自己的变量firstAt
。
First of all you have to find the timestamp for sunday_16_pm
to tell this plugin that the repeating should start on sunday afternoon. 首先,你必须找到
sunday_16_pm
的时间戳告诉这个插件重复应该在周日下午开始。
In order to find this timestamp (that I suppose this should be done dynamically), I wrote the function getDayMillDiff
to calculate the time-difference between now and sunday. 为了找到这个时间戳(我想这应该动态完成),我写了函数
getDayMillDiff
来计算现在和星期日之间的时差。 Afterwards this difference is used to obtain the desired sunday_16_pm
. 之后,这个差异用于获得所需的
sunday_16_pm
。
function getDayMillDiff(refday){
var days = {
monday: 1,
tuesday: 2,
wednesday: 3,
thursday: 4,
friday: 5,
saturday: 6,
sunday: 0
};
if(!days.hasOwnProperty(refday))throw new Error(refday+" is not listed in "+JSON.stringify(days));
var curr = new Date();
var triggerDay = days[refday];
var dayMillDiff=0;
var dayInMill = 1000*60*60*24;
// add a day as long as refday(sunday for instance) is not reached
while(curr.getDay()!=triggerDay){
dayMillDiff += dayInMill;
curr = new Date(curr.getTime()+dayInMill);
}
return dayMillDiff;
}
var today = new Date();
// how many days are between current day (thursday for instance) to sunday, add this difference to this sunday variable
var sunday = today.getTime() + getDayMillDiff("sunday");
// convert timestamp to Date so that hours can be adjusted
var sunday_16_pm = new Date(sunday);
sunday_16_pm.setHours(16,0,0);
// now we can use sunday_16_pm to schedule a notification showing at this date and every past week
cordova.plugins.notification.local.schedule({
id: 1,
title: "Test...",
text: "Test...",
every: 'week',
firstAt: sunday_16_pm
});
One more example: 还有一个例子:
To test getDayMillDiff
for other days than sunday, you can simply pass the string "monday"
onto it (please use always a name listed within the variable days
in getDayMillDiff
): 要在星期日
getDayMillDiff
的其他日子测试getDayMillDiff
,您只需将字符串"monday"
传递给它(请始终使用getDayMillDiff
变量days
列出的名称):
var today = new Date();
var monday = today.getTime() + getDayMillDiff("monday");
var monday_10_am = new Date(monday);
monday_10_am.setHours(10,0,0);
cordova.plugins.notification.local.schedule({
id: 1,
title: "Test...",
text: "Test...",
every: 'week',
firstAt: monday_10_am
});
Hope it helps. 希望能帮助到你。
