怎么将jsp页面的数据转换成json格式的数据？

Answer 1

用ajax可以转换。

jsp页面的数据转换成json格式可以采用js来解析，bookList = new ArrayList<Books>JSONObject json = new JSONObjectjson.accumulate("bookList", bookList);

json.accumulate("pageNum", pageNum);

json.accumulate("totalPages", totalPages);

json.accumulate("totalNum", totalNum);

jsonObj = json.toString();

jsonObj = {"totalNum":5,"bookList":[{"catGrade":null,"sourceCat":"xx","catProseries":"yy"}, {"catGrade":null,"sourceCat":"yy","catProseries":"xx"}],"totalPages":3,"pageNum":2}

function(data){//回调函数

var json = eval("("+data+")"); //将数据转换成json类型var bookList = json.bookList ;

alert(bookList[0].catGrade);
