如何将数组拆分为使用javascript给出的格式？

Question

My data is

["9.968034,77.906814", "8.699679,77.478347", "8.797406,80.895095"]

How can split this to

[
    { lat: 9.968034, lng: 77.906814},
    { lat: 8.699679, lng: 77.478347},
    { lat: 8.797406, lng: 80.895095}
];

Please help me to have a solution...

I tried as

 var jArray = ["9.968034,77.906814", "8.699679,77.478347", "8.797406,80.895095"]; var temp = {}; for(var j=0; j<jArray.length;j++){ var tr = { 'lat' :jArray[j][1], 'lng' :jArray[j][0] } temp.push(tr); } console.log(temp) 

Answer 1

You can try this.

With the help of map() and split() functions.

 let arr = ["9.968034,77.906814", "8.699679,77.478347", "8.797406,80.895095"] let op = arr.map(e => { let temp = e.split(','); return { lat:temp[0], lng: temp[1] }; }) console.log(op); 

Answer 2

You could split an destrucure the array.

 var data = ["9.968034,77.906814", "8.699679,77.478347", "8.797406,80.895095"], result = data.map(s => (([lat, lng]) => ({ lat, lng })) (s.split(',')) ); console.log(result);

Javascript has a built in JSON parse for strings, which I think is what you have:

var myObject = JSON.parse("my json string");

to use this with your example would be:

var jsonData = JSON.parse(myMessage);
for (var i = 0; i < jsonData.counters.length; i++) {
    var counter = jsonData.counters[i];
    console.log(counter.counter_name);
}

Try it, I hope it helps you.

You could use map and ES2015 destructuring assignment like this:

 let data = ["9.968034,77.906814", "8.699679,77.478347", "8.797406,80.895095"] let newArray = data.map(loc => { const [lat, lng] = loc.split(',') return { lat, lng } }) console.log(newArray) 

Answer 5

This will do it for you.

var arrayOfStrings = ["9.968034,77.906814", "8.699679,77.478347", "8.797406,80.895095"];
var arrayOfObjects = [];

for(var item = 0; item < arrayOfString.length; item++){
   var latlng = {};
   var splittedValues = arrayOfString[item].split(",");
   latlng["lat"] = splittedValues[0];
   latlng["long"] = splittedValues[1]
   arrayOfObjects.push(latlng);
}

console.log(arrayOfObjects);

Answer 6

Your loop is correct but you should split string by , delimiter using .split() to getting parts of string.

 var jArray = ["9.968034,77.906814", "8.699679,77.478347", "8.797406,80.895095"]; var temp = []; for (var j=0; j<jArray.length;j++){ temp.push({ 'lat': jArray[j].split(',')[0], 'lng': jArray[j].split(',')[1] }); } console.log(temp); 

Also you can use foreach instead

var temp = [];
jArray.forEach(function(item){
  temp.push({
    'lat' :item.split(',')[0],
    'lng' :item.split(',')[1]
  });
});
