Store JSON data into a variable using Javascript

Question

I have an array variable and the value is shown below:

var data=[{"id":"1"},{"id":"2"}];

but what I need to get the data value from json url http://myweb.com/student/wp-json/wp/v2/posts

the url content is:

[{"id":"1"},{"id":"2"},{"id":"3"},{"id":"4"},{"id":"5"},{"id":"6"}]

without semicolon as ending

The question is how to store the value returned from Json into an variable.

Dont understand your question. Do you have an ajax request which returns data as follows: [{"id":"1"},{"id":"2"},{"id":"3"},{"id":"4"},{"id":"5"},{"id":"6"}]? — Thargor

So, you need to get the JSON data from URL and store in a variable?

You can do following:

function get_data_from_url(url){
    var http_req = new XMLHttpRequest();
    http_req.open("GET",url,false);
    http_req.send(null);
    return http_req.responseText;          
}

var data_url = "http://myweb.com/student/wp-json/wp/v2/posts";
var data_obj = JSON.parse(get_data_from_url(data_url));
console.log("Data object: "+ data_obj);
