- 对象内部数组中追加元素
json对象添加属性
var jsonObj={
'param1':11,
'param2' :22
};
jsonObj. param3='33';
json数组添加元素
var jsonstr="[{'name':'a','value':1},{'name':'b','value':2}]";
var jsonarray = eval('('+jsonstr+')');
var arr =
{
"name" : $('#names').val(),
"value" : $('#values').val()
}
jsonarray.push(arr);
var jsonObj={};// 定义一个json对象
jsonObj.array1=["2","4"];// 增加一个新属性，此属性是数组jsonObj.array1[jsonObj.array1.length]='6';// 数组arr1追加一个元素
jsonObj.array2=["1","3","5"];//json对象中添加元素console.log(jsonObj);
对象内部数组中追加元素

可以看到follow_list_new有10条数据
将follow_list_new对象 08/27 数组中的元素循环追加到follow_list_old对象中 08/27的数组内
