如何在jQuery中使用php json_encoded数组

Question

In my php code, I have

 <?php
      $test = json_encode($array);//$array is a valid multidimensional array
 ?>

I am passing this variable to a javascript function and I am trying to set this variable to javascript.

 <script>
     var test = "<?php echo $test;?>";
  </script>

(To clarify I am using codeigniter framework and for simplicity I did not use how I am sending the variable to the page)

But when I execute the above code, I am getting

Uncaught SyntaxError: Unexpected identifier

I have checked all my syntax.

Thank you in advance.

Answer 1

Don't put the decoded json array inside double quotes in the javascript. Change to this.

var test = <?php echo $test;?>;

Answer 2

It's not required to wrap the output of json_encode in quotes, otherwise it will be interpreted as a string. At which point you'll need to decode it within JavaScript.
