如何使用javascript从api读取JSON数据

Question

Hello I'm trying to read JSON data from an api but it doesn't work when I try to get data from that api works fine and when I try to get the distance value I get undefined.Please help

The code

fetch('https://maps.googleapis.com/maps/api/distancematrix/json?units=meter&origins=Gurd%20Shola%201%20Station,%20Addis%20Ababa&destinations=Bole%20Medhane%20Alem%20Church,%20Addis%20Ababa&key=API_KEY')
  .then(response => {
    return response.json()
  })
  .then(data => {
// Work with JSON data here
console.log(data.rows.elements.distance.value)
 })
  .catch(err => {

 })

the result from the web is just like this

{
   "destination_addresses" : [ "Addis Ababa, Ethiopia" ],
   "origin_addresses" : [ "Addis Ababa, Ethiopia" ],
   "rows" : [
      {
         "elements" : [
            {
               "distance" : {
                  "text" : "6.4 km",
                  "value" : 6386
               },
               "duration" : {
                  "text" : "15 mins",
                  "value" : 901
               },
               "status" : "OK"
            }
         ]
      }
   ],
   "status" : "OK"
}

Change data.rows.elementes.distance.value to data.rows[0].elements[0].distance.value ..

Check for typo here it is elements and not elementes ..

Also rows and elements is an array and if you need to get the distance then you need to get it like rows[0].elements[0].distance ..

 const data = { "destination_addresses" : [ "Addis Ababa, Ethiopia" ], "origin_addresses" : [ "Addis Ababa, Ethiopia" ], "rows" : [ { "elements" : [ { "distance" : { "text" : "6.4 km", "value" : 6386 }, "duration" : { "text" : "15 mins", "value" : 901 }, "status" : "OK" } ] } ], "status" : "OK" } console.log(data.rows[0].elements[0].distance);
