javascript multi-dimensional arrays

Hi all,

I have searched for this pretty much everywhere, and I know the answer should be obvious but I can’t find it.

I have a PHP snippet that outputs a piece of javascript code.

When I ran the snippet as is, everything worked, except for where the multi-dimensional array had [[ .... ]] That would get replaced by nothing (I am assuming that the template parser was doing it’s job there.)

I tried loading it in to a TV, and outputing it that way. Same thing happened. Is there any way that I can output this information so that it works properly? (this is dynamically produced information so I can’t just take the output and stick it in a .js file)

Output from Modx:
var data = {"zoom":15,"garages":[{"id":"1","name":"Akatiff Lot","address":"N. Autumn Street North of Julian Street","phone":"(408) 295-7275","hours":"Open for arena events","rates":"Rates vary by event","discounts":"","directions_link":"http://maps.google.com/maps?q=N.+Autumn+Street+and+Julian+Street,+san+jose,+ca&spn=0.025608369289529875,0.028457164764404297&hl=en","points":}

It is the points location that is the issue.

What it is supposed to look like:

var data = {"zoom":15,"garages":[{"id":"1","name":"Akatiff Lot","address":"N. Autumn Street North of Julian Street","phone":"(408) 794-1090","hours":"Open for arena events","rates":"Rates vary by event ($10-$20)","discounts":"","directions_link":"http://maps.google.com/maps?q=N.+Autumn+Street+and+Julian+Street,+san+jose,+ca&spn=0.025608369289529875,0.028457164764404297&hl=en","points":[[37.33830,-121.90116],[37.33867,-121.90134],[37.33853,-121.90189],[37.33826,-121.90262],[37.33775,-121.90408],[37.33632,-121.90245],[37.33693,-121.90151],[37.33676,-121.90129],[37.33656,-121.90108],[37.33693,-121.90048],[37.33785,-121.90134],[37.33802,-121.90099]]}]};

The code that produces the above:

ob_start();
?>
<script language="JavaScript">
<!--
var data = <?php print_data($modx,$zoom); ?>;
var poiLocations = [ null // 1-indexed.
{foreach from=$points_of_interest item=p}
, new GLatLng({$p->lat}, {$p->lng})
{/foreach}
];
//-->
</script>
<?php
$output=ob_get_contents();
ob_end_clean();
$modx->setPlaceholder(’parking_data’,$output);

I have tried simply echoing $output as well and still get the same thing.

Template call:

[[parking_display? &zoom=`15`]]
[+parking_data+]

Any suggestions?

Thanks,
Bryan

Bryan,

Your arrays are conflicting with the MODx Parser.

That said, see if you can introduce a SPACE before/after each opening/closing bracket to prevent the parser from thinking your JavaScript is a snippet

Example:


...would become...

Thank you very much! It works!

BTW, you may already know this, but you can inject JS code into the header with

or just before the </body> tag with
