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':[]}； 1 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); 1 一下举栗声明json数组串较为复杂并且灵活的格式。   [     {         "dateMonth":"05",         "hopeMoney":"12000",         "data":[             {                 "brickId":"1",                 "brickYear":"2017-05-15",                 "brickWeek":"星期二",                 "brckInfo":[                     {                         "bringMoneyOrExpenditure":"5000",                         "brickClass":"工资",                         "brickIcon":"ion-ios-star-outline"                     },                     {                         "bringMoneyOrExpenditure":"-2000",                         "brickClass":"其他",                         "brickIcon":"ion-ios-star-outline"                     }                 ]             },             {                 "brickId":"1",                 "brickYear":"2017-05-02",                 "brickWeek":"星期六",                 "brckInfo":[                     {                         "bringMoneyOrExpenditure":"10000",                         "brickClass":"工资",                         "brickIcon":"ion-ios-star-outline"                     }                 ]             }         ]     },     {         "dateMonth":"04",         "hopeMoney":"12000",         "data":[             {                 "brickId":"1",                 "brickYear":"2017-04-15",                 "brickWeek":"星期一",                 "brckInfo":[                     {                         "bringMoneyOrExpenditure":"5000",                         "brickClass":"工资",                         "brickIcon":"ion-ios-star-outline"                     }                 ]             }         ]     } ]<br><br><br><br>//我的应用var productList_array = {"userId":member_uid,"productList":[]};<br>$('.main_div').each(function(){<br>    product_id = $(this).data('id');<br>    product_num = parseInt($(this).data('num'));<br>    productList_array.productList.push({"productId":product_id,"quantity":product_num});<br>});<br>console.log(productList_array);<br>productList_array_jsonstr = JSON.stringify(productList_array);<br>console.log(productList_array_jsonstr);<br>return false;

----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}]}
