Is there a list like operator in javascript?

Question

I'm now implement such a task:I need to convert PHP variables to javascript

$arr['name1'] = 'value1';
$arr['name2'] = 'value2';

so that after processing,should be:

<script type="text/javascript">
var name1 = 'value1';
var name2 = 'value2';
...

I hoped to do it this way:

<script>
list(<?php echo join(',',array_keys($arr)?>) = <?php echo json_encode(array_values($arr));?>

Answer 1

Nope, sorry.

You might instead consider simply using json_encode to print the object to the script.

<?php
    $a = array('foo' => 'bar');
    json_encode($a); // returns {"foo":"bar"} which is valid Javascript syntax
?>

<script>var obj = <?php echo json_encode($a); ?></script>

Answer 2

You could use json.

var arr = { "name1" : "value1", "name2": "value2"}

Then to get a value you just access it like a field

var firstVal = arr.name1

Answer 3

Hi, you might want to have a look at PHP JS, it will help you in your conversion tasks. Thanks

Answer 4

Check php.js, they have ported a lot of features of PHP to JS, list() is listed as experimental.

Answer 5

Probably misunderstood the question, but wouldn't this work?

echo "<script>";
foreach ($arr as $k => $v) 
{
    echo "var $k = $v;";
}
echo "</script>";
