How to read and get the count from rest api JSON response?

Off topic

Hi,
I have a json array response like below:

[
	{
		name : john
		dept: Mech
		Rank : A
	}
	{
		name : Mecury
		dept: Science
		Rank : A+
	}
	{
		name : Sana
		dept: Bio
		Rank : B
	}
]

when i try to get the length of the array i couldnt able to do that, because i dont have any prefix on the response i guess.

Is there any way i can get the length from this json array?

A repro in the playground would be nice. It is not directly related to babylon but in general you could do response.length ?

not its throwing an wrong data when i tested on this below code:

var xhr = new XMLHttpRequest();
    xhr.open("GET", "https://jsonplaceholder.typicode.com/posts", true);
    xhr.onload = function(){
        console.log(xhr.responseText);
        console.log(xhr.responseText.length);

    };
    xhr.send();

You need to parse the text response in this case with JSON.parse

5 
var jparse = JSON.parse(responsetext);
    var leng = Object.keys(jparse).length;
    console.log(leng);

tried this code but getting a syntax error:

This works: Babylon.js Playground

Please, focus your topics around Babylon next time :slight_smile:

Your server is returning this so it means you are not sending the expected format, I will move the post to off topic.
