Question

below is what I’m attempting to use for my site, this php page shows up without any issues in Firefox, and Chrome.

For some reason it doesn’t appear to be working up in IE(tested on 8 and 9) I dont really know what is wrong here.

The error I am getting in IE8 is “Not a valid 2d Array” this appears to be coming from the google hosted .js

I’m wondering why this is occuring in IE8 only and not Chrome or Firefox?

Answer 1

var data = google.visualization.arrayToDataTable([
    ['Country','Blocks'],
  <?php
    foreach ($bans as $key => $value)
                print"['$key', $value],\n";
    ?>
    ]);

Will return:

var data = google.visualization.arrayToDataTable([
    ['key1', value1],
    ['key2', value2],
]);

The extra comma at the end of the second one will break it. See this:

http://www.openjs.com/articles/ie/array_comma_problem.php

var sample = {
    'hello':'world',
    'foo':'bar', //This is 'the last comma'
}

alert("Hello World");

http://jsfiddle.net/A5VMW/

In most browsers, the final ‘,’ is optional – its presence will not make any difference in the script. But IE will decide to do something that defies explanation – it just ignores everything after that bit of code. The ‘Hello World’ alert will never be seen in an IE browser.

Also see: https://stackoverflow.com/a/5139395/504299 :

Historically speaking, ES3 disallowed having a trailing comma when defining an object literal. This was one thing that IE did get right, but most other bowser vendors went south and did allow the trailing comma. So technically it was a bug in the other browsers that supported it.
