从jsp我得到多个值字符串数组，
谁能告诉我如何检索和设置我从 javascript 发送的值。
我需要获取值必须将其传递到数据库。
最佳答案
String[] productsBas = request.getParameterValues("product");
String[] pricesBas= request.getParameterValues("price");
String[] qtysBas= request.getParameterValues("qty");
for(int i=0;i<productsBas.length;i++){
get values here using
productsBas[i] & pricesBas[i] and qtysBas[i] then save it
}
关于java - 如何在java中的servlet中获取和传递值？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/16104342/
