I'm try jQuery for dynamic Add/Remove row function, but I meet some question in IE8 , it's clone() objcet cannot modify element name and cannot use javascript form (prhIndexed[i].prhSrc).functionKey, but in FF it works very well, source code as attachment, please give me a favor to solve the problem.
