php array value from data tag to jQuery

Question

I am trying to get array value from data tag to jQuery but not working. Here is my code:

//$b is taking names from text-area separated by comma.
$a = array_map('trim', explode(",", $b));
return <input type="text" id="pct"><button id="pcthit">submit</button><p id="pct_avail"></p></span>
<input type="hidden" id="storageElement" data-storeIt="'.$a.'">';


$("#pcthit").click(function(){
    var pstcde = $("#pct").val();
    var retrieved_string = [];
    var retrieved_string = $("#storageElement").data('storeit');
    if((pstcde != '') && (jQuery.inArray(pstcde, retrieved_string) >= 0 )){
    $("#pct_avail").html('hello');
    }
});

You need to encode the array with json_encode().

return '<input type="text" id="pct"><button id="pcthit">submit</button>
        <p id="pct_avail"></p></span>
        <input type="hidden" id="storageElement" data-storeIt=\''.json_encode($a).'\'>';

Thanks Barmar, I tried with json_encode() but still not working. $("#pct_avail").html(retrieved_string); is giving only bracket "[".

i replaced all the quotes for input, ( " ) with ( ' ) and ( ' ) with ( " ), now it's working. Thanks a lot for your help :),

I just changed the quotes around the data-storeIt value, since json_encode() uses double quotes around all the embedded strings.

wow, it's a easy way rather than changing all the quotes, thanks :)
