ajax形式提交子表单数据到后台

		
	//ajax形式提交子表单数据到后台！
	//用JSON.stringify传递参数，controller中要用@RequestBody注解接收参数
	$("#yourFormBtn").click(function () {
		
		//获取子grid中数据
        $('#gridId').saveRow();
        var gridDatas = $('#gridId').jqGrid('getGridParam', 'data');

		//定义子表数据的数组
        var subArray = [];

			//子表数据的对象
            var subData = {};
			//获取行数据的model
            var subDataModel = gridDatas[item];
            $('#subDataGrid').saveRow(subDataModel.id);
