Button to add Product by reference from Textfield

[Cooolsport]

Hello

 

At the moment I try do develop a simple function where I get the Quantity and than the Product reference and add them diretly to the cart.

 

At the moment though it does nothing

 

function add_to_cart_custom(){
	var params = $('#add_this_to_cart').attr('data-id');
	addToCart(params);
}

<input type="text" name="obr_qty" id="obr_qty" placeholder="{l s='Qty' mod='orderbyrefcsv'}">
		<input type="text" name="obr_ref" id="obr_ref" placeholder="{l s='Reference' mod='orderbyrefcsv'}" class="first" style="width:78%;"/>
		<input type="button" id="add_this_to_cart" name="submit" value="Ok" onclick="add_to_cart_custom();"/>
		

I changed the order by reference or csv module a bit.

 

could anyone help me maybe?
