Saving data to a variable with AJAX/JSON when the column name is numerical: Best practices

When attempting to save a JSON value as a variable from an AJAX response ...

$.ajax({
url:'example.php',
type:'POST',
dataType: 'json',
success:function(data){

    var checkname = data.name;  // works fine
    var check1m = data.1m;      // SyntaxError occurs here

}
});

... and the column name starts with a number (e.g. 1m):

[{"name":"Peter","city":"London","1m":"not attending","2m":"attending"}]

The error received is:

SyntaxError: identifier starts immediately after numeric literal

Is there a way to save the value in the variable (check1m)?

javascriptjsonajax

Answer №1

To retrieve a value, you can use the offset method like so:

 var check1m = data['1m'];

Here's an example: 

var json = [{"name":"Peter","city":"London","1m":"not attending","2m":"attending"}] ;
console.log(json[0]['1m']);

Answer №2

It's as easy as using data["1m"] instead of the previous method

Answer №3

give this a shot

$.ajax({
url:'sample.php',
type:'POST',
dataType: 'json',
success:function(data){

    var nameCheck = data[0]['name'];  // successful
    var checkOneM = data[0]['1m'];     // SyntaxError occurs here

}
});
