以下是table的js

 /* 获取table表格的数据项.*/
        function getTableData() {
            var data = [];
            $("#table_1 tbody tr").each(function(i, item) {
                data.push({
                    "BudgetCode" : $("input[name='BudgetCode']", item).val(),
                    "ClientCode" : $("input[name='tbClientCode']", item).val(),
