java後臺用的輸出流。怎麼在前臺用js怎麼接收
阿新 • • 發佈:2019-02-02
後臺Java程式碼:
@RequestMapping(value = "/friendLinks/friendLinksList.do") public void getfriendLinksList(HttpServletRequest request, HttpServletResponse response, ModelMap modelMap){ response.setCharacterEncoding("UTF-8"); String pageNoStr = request.getParameter("pageNo"); Integer pageNo = 0; try { pageNo = Integer.valueOf(pageNoStr); } catch (Exception e) { pageNo = 0; } Page page = new Page(); page.setPageNo(pageNo); //按分頁條件查詢使用者 List<FriendLinks> linksList = null; try { linksList = friendLinksService.getFriendLinksList(page); //將查出來的友情連結和分頁資訊放到json字串中 JSONArray jsonList = new JSONArray(); JSONObject bj = JSONObject.fromObject(page); jsonList.add(bj); for (FriendLinks links : linksList) { JSONObject obj = JSONObject.fromObject(links); jsonList.add(obj); } response.getWriter().println(jsonList.toString()); response.getWriter().flush(); response.getWriter().close(); } catch (Exception e) { e.printStackTrace(); } return ; }
JS中程式碼:
function fillData(pageNo) { if (pageNo == "") { pageNo = thisPageNo; } var stateValue = $("#stateValue").val(); var titleValue = $("#titleValue").val(); $.ajax({ url:contextPath + "/friendLinks/friendLinksList.do", type:"POST", data:{ pageNo:pageNo, stateValue:stateValue, titleValue:titleValue }, dataType:"json", beforeSend:function () { $("#pageTd a").remove(); }, success:function (data) { var page = data[0]; if (page.count == 0) { var noDataMsg = "<tr><td colspan=\"9\" class=\"xiamian\">無相關資料</td></tr>"; $("#dataBody").html(noDataMsg); var pageMsg = "總記錄數:<strong>0</strong>"+ " 當前頁:<strong>0/0</strong> "+ "<a href='javascript:;'>首頁</a> "+ "<a href='javascript:;'>上一頁</a> "+ "<a href='javascript:;'>下一頁</a> "+ "<a href='javascript:;'>尾頁</a> "; $("#pageButtonBefore").html(pageMsg); } else { var dataMsg = ""; var caozuo = ""; var useOrNot = ""; for (var i = 1; i < data.length; i++) { caozuo = ""; caozuo = caozuo + "<a href='javascript:;' onclick='checkJump(\""+data[i].id+"\")'>檢視</a>"; caozuo = caozuo + "<a href='javascript:;' onclick='editJump(\""+data[i].id+"\")'>修改</a>"; caozuo = caozuo + "<a href='javascript:;' onclick='deleteJump(\""+data[i].id+"\")'>刪除</a>"; if(data[i].status == "0"){ status = "是"; }else{ status = "否"; } dataMsg = dataMsg + "<tr><td>" + i + "</td><td>" + data[i].linkName + "</td><td>" + data[i].linkSite + "</td><td>" + status + "</td><td>"; dataMsg = dataMsg + caozuo; dataMsg = dataMsg + "</td></tr>"; } $("#dataBody").html(dataMsg); var pageMsg = "總記錄數:<strong>"+page.count+"</strong> 當前頁:<strong>"+page.pageNo+"/"+page.totalPage+"</strong> "+ "<a href='javascript:fillData(\"1\");'>首頁</a> "+ "<a href=javascript:fillData(\"" + page.pre + "\");>上一頁</a> "+ "<a href=javascript:fillData(\"" + page.next + "\");>下一頁</a> "+ "<a href=javascript:fillData(\"" + page.totalPage + "\");>尾頁</a> "; $("#pageButtonBefore").html(pageMsg); } }, error:function () { alert("獲取相關資料失敗!"); }});
}
其實能看出來,JS怎麼接收值跟後臺用什麼方式傳沒有多大關係,關鍵是看傳過來的值格式是啥就好了。
傳回來的是字串,那就直接按照字串處理,傳回來的是Json格式的那就直接按照解析Json來處理。
