我正在尝试在启动后加载Select小部件的列表。我已经调用了后端来加载我的模型和列表。
在Select上调用setStore（）会将项目加载到窗口小部件中，还会选择列表中的第一个项目，并将绑定的模型属性更改为第一个项目。
我也尝试使用第二个参数（selectedValue）调用setStore（），但这似乎没有任何影响。
我把一个hack一起抛出，它首先调用setStore（）来引入窗口小部件（选择第一个项目），然后调用set（“value”）来将窗口小部件值和模型属性设置回初始值。此hack导致在表单加载期间在窗口小部件上触发更改事件，这是不可取的。我可以断开/重新连接处理程序，但这只是更多的黑客攻击。
要重新创建此项，请稍微更改dojox / mvc / tests / test_mvc_new_form-kitchensink.html。
首先在构建选择中注释掉商店：
var sel = new Select({
// store: store,
loadChildrenOnOpen: true,
// value: 1,
value: at(selctrl, 'number') // bind to model.number
}, document.getElementById('sel'));
然后在setTimeout（）调用中设置存储（启动后）：
sel.startup();
setTimeout(function () {
sel.setStore(store);
}, 1000);
如果您打算使用声明性示例进行测试，则需要从相应select元素的data-dojo-props属性中删除“store”属性。
该字段绑定到selctrl控制器中的“number”字段，该字段最初设置为“1”。在Select上调用setStore后，小部件和绑定模型属性都将设置为列表中的第一个项目，在本例中为“8”。
这是测试页面，修改了编程和声明性选择小部件：

答案 0 :(得分：0)
ItemFileReadStore被传递给addOption的简单数组所取代。这家商店对我的解决方案来说太过分了。
在从后端（模型和列表）接收所有数据的时间点，为每个Select构建一个数组，并指示所选项目以反映当前绑定的model.property。此实现的唯一问题是需要调用removeOption然后addOption，如果由于页面中的上下文更改而需要将列表重新调整到其列表中。
如果有人深入了解Select with Store的行为如上所述，请发布解释。
