从PHP获取数组值到javascript

Question

how can i get array value from php to javascript, and use the value for other function in javascript? here is my source code:

<?php
    $sSql  = "SELECT * from contactinfo order by description, nama_cp";
    $r1 = $dbconn->execute ($sSql);
    $idset=array();
    $no=1;
    while (($r1) && (!$r1->EOF)) {
        $s1 = $r1->GetRowAssoc(false);
        $idset[$no]=$s1[id];
        $no++;
    }
?>
<script type="text/javascript">
function getdata(valarray){
    //source..
}
 $(document).ready(function() {
     var line=<?php echo($no); ?>;
     var i;
     for(i=1;i<line;i++){
        $("#action"+i).click(function() {//button, that named with action+int
            //var valarray = ??? -------->value of array idset;
            getdata(valarray);//use data array for other function..
        });
     }
 });   
 </script> 

in this code, i want to use valarray in function getdata().

Here is your solution:

var valarray = <?php echo json_encode($idset); ?>; 
console.log('we got: '+ valarray)

When you used alert - you can see the results since it's a json and not test. The best for you will be to use Chrome dev tools (or Firebug on FF) and see in the console the results.
