Question

I have an array being passed from php which looks like:
$resultsArr[123]['A']='q';
$resultsArr[123]['B']='d';
$resultsArr[113]['C']='s';
$resultsArr[113]['A']='ss';
$resultsArr[113]['B']='sd';
$resultsArr[111]['C']='sds';
$resultsArr[111]['A']='vv';
$resultsArr[111]['B']='vv';

i need to access certain values frmo this array using jquery.

i am trying to access it like
keyVal = 123; //dynamically generated
var pri = ‘~$results[‘keyVal’][‘B’]`’

but i am getting a blank value in variable ‘pri’
How can this be solved?

Answer 1

Could you not convert it to a JSON Array and then use it directly in Javascript, rather than picking out individual elements of the array?

<script>

    var myArray = <?php echo json_encode($resultsArr); ?>;

</script>

Then use jQuery each to read the array.

This would give you greater flexibility in the long term of what was available to javascript for reading and manipulation.

EDIT

You can read a specific element like so, this will alert “vv”:

<script>
    var myVar = myArray[111].A;
    alert(myVar);
</script>
