【问题描述】:
我遇到了无法绑定我的数据然后使用 cshtml 显示它的问题。我尝试了不同的方法来制作可观察的数组,我在想,我的主要问题来自于试图利用我所谓的“有界数据”......以下是我的 cshtml(c#-html) 代码,然后是我的 js 代码。
<!--*****Unfinished*****-->
<td>
<label class="element-label">Continuous (Vibratory) Acceleration</label>
<select class="form-control device-family-selector" , data-bind="options: changeAuxFlange.availableVForces, optionsText: 'forceName', value: changeAuxFlange.selectedForces, optionCaption: 'Choose a force...'"></select>
</td>
<td>
<input style="width:50px; text-align:right;" , data-bind="text: changeAuxFlange.selectedForces" />

<label class="element-label">Maximum (Shock) Acceleration</label>

【问题讨论】:
-
没有看到任何应用绑定的调用。
-
是的,对不起,我有。我已经包含了一些您可能需要帮助我的信息。
-
看不到 changeAuxFlange 与您的视图模型相关联甚至实例化的位置。
-
data-bind属性中的项目似乎与它们绑定的内容无关(Application上的属性)
