Is there a way I can create an object from this data stored in a string, coming from the google API:
"recurrence": [
"RRULE:FREQ=WEEKLY;UNTIL=20181213T235959Z;BYDAY=TH"
],
I can use string methods, but I wondered if there was a better way.
Something like:
recurrence: {
frequency: "weekly",
until: "yy/mm/dd",
byday: "th"
}
Any ideas?
The Google API Documentation itself provides no other format. Hence your only option would be to apply simple string transformations. Such as :
let targetObj = {};
for(const entry of res.recurrence.substr(5).split(';)) {
const [key, value] = entry.split('=');
targetObj[key] = value;
}
You will need to split multiple times and convert key to lower case.
var api = {"recurrence": ["RRULE:FREQ=WEEKLY;UNTIL=20181213T235959Z;BYDAY=TH"]};
var obj = {};
var str = api.recurrence[0];
var arr = str.split(";");
arr.forEach(function(element){
var pair = element.split("=");
var key_array = pair[0].split(":");
var key = key_array[key_array.length-1].toLowerCase();
var val = pair[1];
obj[key]=val;
});
console.log(obj);You can use a regex to match what you want and create your object.
const obj = { reference: ["RRULE:FREQ=WEEKLY;UNTIL=20181213T235959Z;BYDAY=TH"] };
const regex = /\w+=\w+/g;
const extract = (obj) =>
obj.reference.reduce((acc, val) => {
val.match(regex).forEach((match) => {
const [lVal, rVal] = match.split('=').map(d => d.toLowerCase());
acc[lVal] = rVal;
});
return acc;
}, {});
console.log(extract(obj));Look at my solution
var str1 = "RRULE:FREQ=WEEKLY;UNTIL=20181213T235959Z;BYDAY=TH";
var str2 = str1.split(':')[1].split(';');
// console.log(str2.split(';'));
var x = str2.map((s)=>{
return s.split("=");
});
var recurrence = {};
x.forEach((ar)=>{
if(ar[0] == 'UNTIL')
ar[1] = moment(ar[1]).format('DD/MM/YYYY');
recurrence[ar[0]] = ar[1];
});
console.log(recurrence);<script src="https://momentjs.com/downloads/moment.js"></script>
