php file send variable to .js external file

Question

From jquery file to php:

$.post('http://botk-online.com/play2.php', {
 'rate': Pontuacao.misses
});

How to modyficate this code to pass $data variable from php file to js external file and read it value.

Are you wanting some Javascript in an external file loaded on the calling page to interact with the $data returned from your play2.php script? — Jared Farrish

You want to use the success handler: api.jquery.com/jQuery.post/#example-5 — Jared Farrish

PHP

<?php

  $result = array('data' => 'this is some data');
  echo json_encode($result);

Javascript:

$.ajax({
    url: 'http://botk-online.com/play2.php',
    type: 'post',
    data: {
        rate: Pontuacao.misses
    },
    dataType: 'json',
    success: function(json) {
        alert('Data is: '+json['data']);
        // Alerts: 'Data is: this is some data'
    }
});

@Dave, it works for me if i want to pass rate variable from js to php but i can't send $value from php to external js file.

How do you mean send $value from php to external js file - is the file already loaded in the browser, or do you need to load the other file into the browser, or call a function defined in another file, or something else?

File play2.php is open and I have to send $value to file.js for example by form

How do you mean send it to the file? Where is file.js?

Use the success handler, which will run if the code returns successfully:

jQuery.post( url [, data] [, success(data, textStatus, jqXHR)] [, dataType] )

Note the , success(data, textStatus, jqXHR) above. For example:

$.post('http://botk-online.com/play2.php', {
        'rate': Pontuacao.misses
    }, function (data) {
        doStuff(data);
    }
});
