//-----------------------2016年12月12----------------------------------

1、html页面中div写了data-bind=“文本类型:取的名字”的话,在js中就要定义初始化   --->取的名字:ko.observable(0)/ko.observable(“”)/ko.observable([])

2、有时html页面中可直接绑定数据源中的字段,直接显示(例:采购录入中的添加采购计划显示的库存数量及价格等等)格式: data-bind="text: $data.GOODSNAME"

3、按钮的另一种写法: <div data-bind="dxButton: {
                                                 text: '加入预选计划',
                                                 type:'success',
                                                 onClick: $parent.addplane,
                                                 disabled:!$parent.BuyNumber.value(),
                                                 },
                         visible:$data.GENQTY">
               </div>
                       <div data-bind="dxButton: {
                                                   text: '关闭商品详情',
                                                   type:'normal',
                                                   onClick: $parent.colsegoodsinfo,
