json 拼二维json数组

js声明数组 以及向数组中添加as移除json数据

JavaScript声明JSON数组的方法:

//部分条件，在数据渲上数据要求是数组格式而非json数组格式，取arrayJson.dataList
var arrayJson = {'dataList':[]}；

2
向数组中添加json串

arrayJson.dataList.push({'name':'dataName'});
1
移除所有数组中数据

arrayJson.dataList.splice(0,arrayJson.dataList.length);

一下举栗声明json数组串较为复杂并且灵活的格式。

//我的应用

----注意：引号一定是双引号------想要这种格式
{"userId":3,"productList":[{"productId":1157,"quantity":3},{"productId":1158,"quantity":1}]}

var productList_array = {"userId":member_uid,"productList":[]};
$('.main_div').each(function(){
    product_id = $(this).data('id');
    product_num = parseInt($(this).data('num'));
    productList_array.productList.push({"productId":product_id,"quantity":product_num});
});
console.log(productList_array);
productList_array_jsonstr = JSON.stringify(productList_array);
console.log(productList_array_jsonstr);
return false;
