JSON响应返回undefined

First use 'json_decode' to convert array to JSON response

$test = [ "connections" => [ [  "title" => "Connection 1", "date"  => "01-26-2010", "id" => "1" ] ] ];

echo json_encode( $test );

and then process the JSON response in the front-end side.

$.get( 'http://cnbusiness.nextdayhost.com/ajax/get_business_connections', function(e){
   console.log( e.connections );
});

but unfortunately it returns 'undefined'

A view of the response using a JSON editor

I can do this

$.get( 'http://cnbusiness.nextdayhost.com/ajax/get_business_connections', function(e){
  $.each(JSON.parse(e),function(i,e){
    $.each(e,function(i,e){
        console.log(e.title);
    });
  });
});

which surely returns the data that I want but I prefer not to do a second loop.

any idea, help please?

Try this. I'm sure you have no header('Content-type:application/json') in you PHP if I'm not mistaken. If you don't have, It will return as a string. You need to parse it by using $.parseJSON of jQuery built in method

$.get('http://cnbusiness.nextdayhost.com/ajax/get_business_connections', function(e) {
  $.each($.parseJSON(e),function(i,e){
    // code here ...
  });
});

parse output to json, plus, because e.connection was an array,

if you want to get title from connection you can do like

e = JSON.parse(e)
console.log(e.connections[0].title)
