json_encode将php数组传递给javascript数组

Question

I have a more dimensional php array that i want to pass to a javascript array.

This is the array:

 $this->_db_list_arrray[$this->getID()][$key] = $row; 

its like "16":[[{"article_no_internal":"9987213"}]] and so on. I encode it like this:

 $shipping_part_list_array = json_encode($db_obj->getArticleList($elements)); 

and in javascript

 alert("<?php echo $shipping_part_list_array; ?>"); 

but the alert only shows [].

Is there a better way to pass php array to java script array?

array(1) {
  [16]=>
  array(2) {
    [0]=>
    array(1) {
      [0]=>
      array(2) {
        ["article_no_internal"]=>
        string(6) "999184"
        ["article_name_internal"]=>
        string(29) "Geschenkbox Kerzenschein 2011"
      }
    }
    [1]=>
    array(1) {
      [0]=>
      array(2) {
        ["article_no_internal"]=>
        string(6) "999184"
        ["article_name_internal"]=>
        string(29) "Geschenkbox Kerzenschein 2011"
      }
    }
  }
}

this is in my console, now i need to parse to get the right data. Thank you

您需要添加单引号来提醒您的JSON字符串：

alert('<?php  echo $shipping_part_list_array; ?>');

You should not put double quotes around the JSON encoded value; just the following will do:

alert(<?php echo $shipping_part_list_array; ?>);

Though, for debugging purposes the following would be better:

console.log(<?php echo $shipping_part_list_array; ?>);

Lastly, to assign it to a JavaScript variable:

var list = <?php echo $shipping_part_list_array; ?>;
