json编码的php数组在javascript中返回undefined

Question

This is a follow up to a previous post.

I'm attempting to pass some data to javascript via json_encode.

I thought I would be able to put the data in to a javascript array as follows:

    var data = [<?php echo json_encode($result_array); ?>];

But when I try to call values they return as undefined. I imagine that it might be putting the data as a singular string inside the array.

If anyone can provide advice that would be great. Thanks a lot!

如果$result_array是php中的数组，那么你只需要：

var data = <?php echo json_encode($result_array); ?>;
