double quotes in forms attributes are converting to &quote;

Hi,

I am creating a new node form, in which I am adding a button. I am trying to add an attribute to this button, which is an onClick property. It is shown below.

'#attributes' => array('onClick' => 'checkimg(document.getElementById("uploadform")); return false;')

But when I view the html code that is generated the double quotes are convering to ". I tried many ways like the following.

1)
$var = 'checkimg(document.getElementById("uploadform")); return false;';
'#attributes' => array('onClick' => $var)

2)
$var = "checkimg(document.getElementById('uploadform')); return false;";
'#attributes' => array('onClick' => $var)

But nothing worked.

Can you please let me know how to add double quotes in the above example.

Thank you,
Raj.
