In my Dataobject i am trying to pass variables with Requirements::javascriptTemplate ...

class Item extends DataObject {
.........
public function getCMSFields() { 
	
  		$fields = parent::getCMSFields();
		Requirements::javascriptTemplate('mysite/javascript/Item.js', array('Title' => $this->Title));

..........

As i expected, editing my Item- DataObject within a GridField should always pass $this->Title.
But doesnt.
In Item.js i call alert('$Title')
but
$this->Title always has a Value of the very first-called Item.
How can i force updating the variable?
thanks.timo.

I think you need to set the $uniquenessID parameter to require the file more than once.

Requirements::javascriptTemplate(
	'mysite/javascript/Item.js', 
	array('Title' => $this->Title),
	'mysite-javascript-Item-' . $this->ID
);

Though, I don't know if this works. Never tried. Maybe it would be better to require the javascript in the init() method and add a event listener for whatever you're trying to do in getCMSFields()...

Hi Devlin!
ive tried your suggestion but
as i need to access the javascript in cms the init- function doesnt work. also the unique part didnt do it.
found this:
http://www.silverstripe.org/community/forums/general-questions/show/49384
or do i miss something?
any further ideas?

I found this: http://takeaway.bigfork.co.uk/a-beginners-introduction-to-using-entwine-in-silverstripe
Also: http://docs.silverstripe.org/en/developer_guides/customising_the_admin_interface/javascript_development/

Maybe something like this -- js only though

public function getCMSFields() {
	$fields = parent::getCMSFields();

	Requirements::customScript("
		(function($) {
			$.entwine(function($) {
				// find Title input field
				$('#Form_ItemEditForm_Title').entwine({
					onmatch: function() {
						// alert(this.val());
						console.log(this.val());
					}
				});
			});
		})(jQuery);
	");

	return $fields;
}

Good luck.
