Accessing smarty multidimensional array values using jquery

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?

can you tell us where you have included this code? in your parsed html or your source php file? keep in mind, jquery is client-side and smarty (php) server-side, means jquery doesn't know anything form php-code and analog — donald123

the array part is in php and has been passed on to the html using smarty. the jquery part is in the template itself — user1085195

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>

Convert it to what? You can use jQuery to iterate over the JSON array and read its values. If you know which elements you want you can do var myVar = myArray[111].A; I will do an edit for you in my answer.....

i am not getting the array in json format from php, is there an equivalent for json_encode in jquery?

rodneyrehm Over a year ago

you should be able to JSONify your data in Smarty: {$results|json_encode}

In php use :

$ResultsArr = json_encode($resultsArr);

$this->jsonResultsArr = $ResultsArr; //its seems u r using smarty.

In javascript

jsonResultsArr = "~$jsonResultsArr`";

requireValue = jsonResultsArr[111].A;
