Question

我在cshtml中使用了这样一个简单的选择列表

model.availableCountries = ko.observableArray(['France', 'Germany', 'Spain']);

并将以下数据分配给脚本中的选项。

<select data-bind="options: model.contacts,
  value: model.selectContactName,
  optionsText: 'Name',
  optionsCaption: 'Select name'">
</select>

但它并没有绑定任何价值。调试时模型具有此值。我也试过

Dim srcRng As Range
dim trgRng  As Range
Dim iii As Long
Dim jjj As Long
Dim iRowStart As Long

Set srcRng = Sheets("your_source_sheet").Range("source_range")
Set trgRng = Sheets("your_target_sheet").Range("target_range")
iRowStart = 4

For iii = iRowStart To UBound(srcRng(), 1)
    For jjj = 1 To UBound(srcRng(), 2) ' <~~ necessary only if you were dealing with more than one column 
        With trgRng
            If srcRng(iii, jjj).Value <> "" Then .Cells(.Rows.Count + 1, jjj).Value = srcRng(iii, jjj).Value
        End With
    Next jjj
Next iii

Set srcRng = Nothing
Set trgRng = Nothing

这甚至没有显示标题。我有什么遗失的吗？

基于您的问题的基本示例。

＆＃13;

const viewModel = {
    availableCountries: ko.observableArray(['France', 'Germany', 'Spain']),
    countryPlaceholder: 'Where do you live?',
    selectedCountry: ko.observable(),
};

ko.applyBindings(viewModel);

＆＃13;

<select data-bind="options: availableCountries,
  value: selectedCountry,
  optionsCaption: countryPlaceholder">
</select>

<p data-bind="visible: selectedCountry">
    You selected: <span data-bind="text: selectedCountry"></span>
</p>
