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;
}
