做过的项目中曾经有这样的需求:货品录入(商品入库),弹框弹出所有的货品(很多),选择其中的一个,则下次弹框弹出所有货品时不再显示选择了的那件货品。当然,录入功能...
整个示例主要就是将HT for Web的DataModel数据模型信息进行序列化和反序列化,这个过程很简单通过dataModel.serialize()将模型序列化成JSON字符串,通过dataModel.deserialize...['DataCount'] = dataModel.size(); console.log(dataModel.size() + ' datas are saved'); return...value; } function restore(dataModel){ var value = window.localStorage['DataModel']; if(value...value; } function restore(dataModel){ var value = getCookieValue('DataModel'); if(value){...() + ' datas are saved'); }; return dataModel.serialize(); } function restore(dataModel){

在服务端我们该如何创建 HT 的 DataModel 和 ForceLayout 呢?.../build/ht-debug.js').ht, dataModel = new ht.DataModel(), reloadModel = require("...../util.js").reloadModel; reloadModel(dataModel, { A: 3, B: 5 }); require("../../.....(edge); return edge; } function reloadModel(dataModel, info){ dataModel.clear(); var ip...; i++) { var iNode = createNode(dataModel, ip + count++); createEdge(dataModel, root,
例子地址:http://hightopo.com/guide/guide/core/datamodel/examples/example_datamodel.html ?...= new ht.DataModel(); g3d = new ht.graph3d.Graph3dView(dataModel); g3d.setGridVisible(true);//设置网格可见...dataModel.sm().ld()) return; dataModel.remove(dataModel.sm().ld()); } function clearDataModel(){...ht.SelectionModel管理 DataModel 模型中 Data 对象的选择状态, 每个 DataModel 对象都内置一个 SelectionModel 选择模型,控制这个 SelectionModel...即可控制所有绑定该 DataModel 的组件的对象选择状态, 这意味着共享同一 DataModel 的组件默认就具有选中联动功能。
接下来 HT 将利用 ht.Default.xhrLoad 函数载入 JSON 场景,并用 HT 封装的 DataModel.deserialize(json) 来反序列化,并将反序列化的对象加入 DataModel...我们这边通过在 JSON 中设置 Data 对象的 tag 属性,在代码中通过 dataModel.getDataByTag(tag) 函数来获取该 Data 对象: var fan1 = dataModel.getDataByTag...('fan1'); var fan2 = dataModel.getDataByTag('fan2'); var camera1 = dataModel.getDataByTag('camera1');...var camera2 = dataModel.getDataByTag('camera2'); var camera3 = dataModel.getDataByTag('camera3'); var...redAlarm = dataModel.getDataByTag('redAlarm'); var yellowAlarm = dataModel.getDataByTag('yellowAlarm
; [heightArr addObject:height]; } // 设置头视图的内容 - (void)setDataModel:(PostDaraModel *)dataModel...{ _dataModel = dataModel; [_iconView sd_setImageWithURL:[NSURL URLWithString:_dataModel.face]...placeholderImage:[UIImage imageNamed:@"touxiang_moren"]]; _nameView.text = _dataModel.username; _...timeView.text = _dataModel.addtime; _titleView.text = _dataModel.title; _textView.text = _dataModel.content...) { // NSLog(@"%@", _dataModel.imgs); botLineY = CGRectGetMaxY(_picView.frame) + 14
; bool isCheck; int likeCount; ItemModel(this.title, this.isCheck, this.likeCount); } class DataModel...return ListView.builder( itemBuilder: (context, index) { return Selector(...Expanded( child: Selector( shouldRebuild: (pre, next) => pre.shouldListRebuild..., selector: (context, dataModel) => dataModel, builder: (BuildContext context, DataModel dataModel..., DataModel>,这里只借助了Selector的shouldRebuild功能,所以并没有对数据做筛选,完整的代码大家请参考Dojo中的实现。

采用QuadTree算法将大大减少需要测试碰撞的次数,从而提高游戏刷新性能,本文例子基于HT for Web的图形引擎,通过GraphView和Graph3dView共享同一数据模型DataModel,...我构建了HT的GraphView和Graph3dView两个组件,通过ht.widget.SplitView左右分割,由于两个视图都共享同一DataModel,因此我们剩下的关注点仅是对DataModel...所有代码如下供参考: function init(){ d = 200; speed = 8; dataModel = new ht.DataModel();...g3d = new ht.graph3d.Graph3dView(dataModel);...g2d = new ht.graph.GraphView(dataModel); mainSplit = new ht.widget.SplitView(g3d

DateModel 作为承载 Data 数据的模型,管理着Data数据的增删以及变化事件派发, HT 框架所有组件都是通过绑定 DataModel,以不同的形式呈现到用户界面;同时组件也会监听 DataModel...var dataModel = new ht.DataModel(); var graphView = new ht.graph.GraphView(dataModel); 通过以下代码来进行一些基础操作上的设置...flag); changeAlarmColor(dataModel, 'Alarm2', flag); changeAlarmColor(dataModel, 'Alarm3', flag);...flag; }, 2000); function changeAlarmColor(dataModel, tag, flag) { var tag = dataModel.getDataByTag...setInterval(function () { changePumpState(dataModel, 'pump1'); changePumpState(dataModel, 'pump2'
