Loading the variable of php in javascript continuously

advertisements

I am currently trying to draw some dynamically loaded graphs using google's visualization tools.

I want to pull the data from an sql database. I have a php script (getnumber.php) that is capable of doing so.

I am trying to use this php script within my javascript that draws the graphs.

<html>
<head>
<!--Load the AJAX API-->
  <script type="text/javascript" src="https://www.google.com/jsapi"></script>
  <script type="text/javascript" src="jquery.js"></script>
  <script type="text/javascript">
  function drawChart(Z)
  {
    tmpdata = new google.visualization.DataTable();
    datalist.push(tmpdata);
    datalist[Z].addColumn('string', 'Complete');
    datalist[Z].addRows([['Finished', $.ajax({url:"getnumber.php"})], ['Incomplete', 10]]);
    .
    .
    .
  }
  window.setInterval("drawChart()", 1000);
</script>

I realise that this use of $.ajax is completely wrong but I'm stumped!

You should try using either $.post() or $.get() functions instead of using the basic ajax one. Anyways, you can manipulate the data in thsoe 3 functions this way

$.post('getnumber.php',function(data){
/* Do whatever you want with the data you grabbed from the php page. */
});

I'm not sure of what your question is exactly, but I hope this will help you.

Have a nice day!

EDIT: The functions themselves don't contain the data, it is contained into the function(data){} portion of the $.ajax() call.

Edit2: The $.ajax(); function has a parameter called success(data, textStatus, jqXHR)which can be used, compared to the two other functions.
