php jquery json request each

Question

my jquery is

<script type="text/javascript">
// <![CDATA[
$(document).ready(function() {
$.ajaxSetup({ cache: false }); 
setInterval(function() {
$('#divToRefresh').load('get.php');
}, 100);  
});
// ]]></script>

the result of get.php is

{"dir":"down","sym":"oo","b":"1.35460","a":"1.35465"} {"dir":"down","sym":"pp","b":"1.64263","a":"1.64273"} {"dir":"down","sym":"qq","b":"104.498","a":"104.502"} {"dir":"up","sym":"rr","b":"0.88183","a":"0.88188"} {"dir":"down","sym":"ss","b":"1.09551","a":"1.09558"}

ONE : 1.35451 / 1.35454   |     TWO : 171.880 / 171.892   |     GBP / NZD : 1.97260 / 1.97316

You can format the desired output in get.php itself, Since you have used .load() — Krish R

Instead of loading the data directly to 'divToRefresh' you can use a callback function to reformat the data. I am assuming that the data you are receiving is a PHP array so you will need to parse it to JSON format so you can conveniently access it via Javascript.

$('#mydiv').load('get.php',function(data) {
        var json = JSON.parse(data);
        var formatted_output = json.dir + '/' + json.sym;//do whatever formatting you want
        $('#mydiv').html(formatted_output);
    });

The result you are sending from the PHP file is not a valid JSON for a multi dimensions array. If you are sending it all at once it should be in the following format (or you will have problems parsing it):

[{"dir":"down","sym":"oo","b":"1.35460","a":"1.35465"},{"dir":"down","sym":"pp","b":"1.64263","a":"1.64273"},{"dir":"down","sym":"qq","b":"104.498","a":"104.502"},{"dir":"up","sym":"rr","b":"0.88183","a":"0.88188"},{"dir":"down","sym":"ss","b":"1.09551","a":"1.09558"}]

Basically every group of elements such as {element,element,element} need to be separated with a comma and the entire json should be wrapped with [] i.e [{element,element},{element,element},{element,element}]

You can then build a formatted text from the individual elements:

var formatted_output = json[0].dir + '/' + json[0].sym + ...

Hope this helps!

Is this the result you receive ALL AT ONCE? or at different times, 1 row at a time? You can access them by 'json.dir', 'json.sim', etc.;
