You have lots of error through out the code man. Don't know what are you trying to achieve.

If you just want to pass the values of product.price and product.name to the call function, try this

<input type="button" onclick="call('<%= product.price %>','<%= product.price %>');" value="Press" />

Then on the function like below,

function call(harga,nama){

    var quantity=prompt("Insert Quantity");
    quantity = isNaN(parseFloat(quantity)) ? 0 : parseFloat(quantity);
    var pri = isNaN(parseFloat(harga)) ? 0 : parseFloat(harga);
    alert("unit price RM" + pri);
    var price= quantity * pri;
    alert("total price : " + price);

    // specify your rest code over here 

}

Hope this helps you.
