删除字段名称形式json对象

Question

I am planning to have coordinates sent to the google maps API but i am unable to delete the field name from my json object in order to send the parameters through.

Object {TempPoints: "{lat: 51.478,lng: -3.192},{lat: 51.478,lng: -3.192…{lat: 51.47840998047034,lng: -3.1926937697490536}"}

how do i remove 'TempPoints:' from the object

desired output

Object {"{lat: 51.478,lng: -3.192},{lat: 51.478,lng: -3.192…{lat: 51.47840998047034,lng: -3.1926937697490536}"}

essentially i am trying to recreate something like this

flightPlanCoordinates = [{lat: 51.478,lng: -3.192},{lat: 51.478,lng: -3.192},{lat: 51.478,lng: -3.192},{lat: 51.47845554862494,lng: -3.1928923123350774},{lat: 51.47848027862647,lng: -3.1929894662780804}];

PHP Code as requested

$sql = $dbh->prepare("SELECT TempPoints FROM session WHERE CustomerID = 2 ORDER BY SessionID DESC LIMIT 1"); 
    $sql->execute(); 
    $row = $sql->fetch(PDO::FETCH_ASSOC);

    $para = implode(" ",$row);
    echo json_encode($row);

Answer

Object {TempPoints: "{lat: 51.478,lng: -3.192},{lat: 51.478,lng: -3.192…{lat: 51.47840998047034,lng: -3.1926937697490536}"}

Answer 1

Objects need to have key:value pairs so your desired output is not valid syntax.

It looks like you might want an array of objects:

var array = [
    {
        lat: 51.478,
        lng: -3.192
    },
    {
        lat: 51.478,
        lng: -3.192
    },
    {
        lat:51.47840998047034,
        lng: -3.1926937697490536
    }
];
