pass php array to jquery

Question

Can someone please give me a simple example how should jquery $.ajax syntax look like in order to pass array from php to jquery.

On server side I have:

$a=array(1,2,3,4,5); 
echo json_encode($a); 

So, I'd like get this to js and have:

 js_array=[1,2,3,4,5]; 

I'd really appreciate any help, cause I've been trying for some time now and no luck.

Thank you!

• Matthew: You should set a proper content type in the PHP code, like header("Content-type: application/json");.

Answer 1

$.ajax({
 method: 'GET', // or POST
 url: 'yourfile.php',
 dataType: 'json',
 data: {}, // put data to be sent via GET/POST into this object if necessary
 success: function(response) {
 // response is your array
 }
});

• Newman1510: Thanks!!! I was doing the same thing for two hours and didn't realize 2 things. First, it's "dataType" not "datatype" and second, I was echoing wrong format from php in the first plase.Soo...THANK YOU!

Answer 2

you can either use:

$.ajax({
 url: 'url',
 dataType: 'json',
 success: function(data){
 //do something with data
 }
});

or:

$.getJSON('url', function(data) {
 do something with data
})
