无法从PHP json_encode解析JS中的JSON对象

Question

I have an array in PHP, which I pack to JSON object with _json_encode(..)_ . Then I send it to JS function as parameter. When I want to parse the object in Javascript with eval(..) nothing happens (there is an error behind the curtains I guess). What could be wrong?
Code:

<script type="text/javascript">
    function testFun(inArr) {
      var obj=eval('('+inArr+')');
      alert(obj.m); //alert(obj) also doesnt work
    }
</script>  


//PHP
$spola_array = array('m' => 1, 'z' => 2);
$json_obj=json_encode($spola_array);
echo '<script type="text/javascript">testFun('.$json_obj.');</script>';

It's already parsed since you're outputting it as an object literal and not a string. That will look like:

<script type="text/javascript">testFun({m: 1, z: 2});</script>

So in your function, it's just:

alert(inArr.m) //1

You would only need to parse it if it were a string:

<script type="text/javascript">testFun('{m: 1, z: 2}');</script>
