How to use Knockout's data-bind attribute in Mvc helpers like Html.EditorFor()
提问by Vlado Pand?i?
I tried this
@Html.EditorFor(model => model.Name, " ", new { data_bind = "value:firstName" });and other possible overloades but none of them seem to work.
我尝试了这个
@Html.EditorFor(model => model.Name, " ", new { data_bind = "value:firstName" });和其他可能的重载，但它们似乎都不起作用。
The rest of code:
其余代码：
<script type="text/javascript">
$(document).ready(function () {
function AppViewModel() {
this.firstName = ko.observable("");
this.lastName = ko.observable("");
}
ko.applyBindings(new AppViewModel());
});

Your 3rd parameter to EditorFordoes not do what you think it should be doing.
您的第三个参数 toEditorFor没有做您认为应该做的事情。

EditorForcannot add HTML attributes to the element. Use TextBoxForinstead:
EditorFor无法向元素添加 HTML 属性。使用TextBoxFor来代替：
@Html.TextBoxFor(model => model.Name, new { data_bind = "value:firstName" });

I understand I'm a bit late on this one, but here's a solution I've been using.
我知道我在这个问题上有点晚了，但这是我一直在使用的解决方案。
Pass the name of the field (in this case name) to the editor template as part of the additionalViewDatalike so:
将字段的名称（在本例中name）传递给编辑器模板，作为其中的一部分，如下additionalViewData所示：
@Html.EditorFor(t => t.name, "", new { fieldName = "name" })
Then in your editorTemplateyou can have this:
然后在你的editorTemplate你可以有这个：
@{
var fieldName = ViewData.Where(v => v.Key == "fieldName").FirstOrDefault().Value;
}
@Html.TextBox("", Model, new { data_bind = "value:"+fieldName })
Hope this helps someone.
希望这可以帮助某人。
