首先你要导入相应的json的jar包
大概就是这么多，网上下载下来导进去就行啦
Java代码：(此处写的list4 里面存的是HlsPlay这个对象，我们要把这个list4里面所有的对象显示到前端 前段提交查询指令以后就调用这个方法，然后返回给前端的js处理)
1 public String getAll() { 2 JSONArray array = new JSONArray(); 3 for (HlsPlay play : list4) { 4 JSONObject obj = new JSONObject(); 5 try { 6 obj.put("name", play.getCname()); 7 obj.put("count", play.getCount()); 8 obj.put("LAtime", play.getLAtime()); 9 obj.put("rellname", play.getName()); 10 } catch (Exception e) { 11 } 12 13 array.add(obj); 14 } 15 return array.toString(); 16 }
JavaScript代码：
function getInfo(){ $("#informations").html(""); $.post("HlsView",{choice:'get',url_name:"",rtsp:"",ZSflg:""}, function(data) {//JQ提交 // console.log(data) var counter=0; $.each(data,function(i,v){ counter=counter+1; var insertText = '<tr><td>'+counter+'</td><td>'+v.name+'</td><td>'+v.count+'</td><td>'+v.LAtime+'</td><td><p id="'+v.rellname+'" onclick="deleteAccess(this)" style="color:blue;font-weight:bold ;text-decoration:underline">删除</p></td></tr>'; //下面这个方法是把这些HTML插入到指定ID（此处是information）后面 document.getElementById("informations").insertAdjacentHTML("afterBegin",insertText); }); }, "json"); }
