js兼容Firefox

代码要完整
这样我好测试我更改的对不对啊
下面我能凭借我的习惯更改下;不知道对不对
估计window.opener.form_form.order_product_id.value=order_product_id;
window.opener.form_form.order_id.value=order_id;
更改成
var win = window.opener;
win.document.getElementById('form_form').getElementById('order_product_id').value = order_product_id;
win.document.getElementById('form_form'').getElementById('order_id').value = order_id;
