js json对象操作

参数解析：

sourcelist是json对象[{id:1,name:张三}]

targetlist是json对象[{roomid:1}]

返回值list是json对象[{id:1,name:张三, testname: "testname" }]

构造list，最外层是数组，内层是单个json的json对象，用var listtemp = { testname: "testname" };来声明一个json对象，其中 testname: "testname"没有任何意义，只是单纯构造json对象而已

//把sourcelist中包含targetlist的数据返回到list中
???function IsContains(sourcelist, targetlist) {
???????var list = [];
???????var listtemp = { testname: "testname" };
???????var k = 0;
???????for (var i = 0; i < sourcelist.length; i++) {
???????????for (var j = 0; j < targetlist.length; j++) {
???????????????if (sourcelist[i].id == targetlist[j].roomid) {
???????????????????listtemp.id = sourcelist[i].id;
???????????????????listtemp.name = sourcelist[i].name;
???????????????????list.push(listtemp);
???????????????????listtemp = { testname: "testname" }
???????????????}
???????????}
???????}
???????return list;
???}
