Html.EditFor Onchange Event
提问by user2739679
I am developing an MVC4 application.
I want to change IsChangedfield in my Model, when model.ExternalVenderNois changed.
我正在开发一个 MVC4 应用程序。 当model.ExternalVenderNo更改时，
我想更改模型中的IsChanged字段。
Below are codes on View page
以下是查看页面上的代码
<div class="editor-field">
@Html.EditorFor(model => model.ExternalVenderNo, new { @onchange = "OnChangeEvent();" })
@Html.ValidationMessageFor(model => model.ExternalVenderNo)
</div>
and
和
function OnChangeEvent()
{
alert("value is changed");
@{ Model.IsChanged = true;
}
}
To check whether OnChangeEventis being called , i put alert.
But alertis also not working.
it means OnChangeEventis not beign called.
为了检查是否正在调用OnChangeEvent，我放置了alert。但警报也不起作用。
这意味着OnChangeEvent没有被调用。
I just want to change IsChangedfield to true, when model.ExternalVenderNois changed.
当model.ExternalVenderNo更改时，我只想将IsChanged字段更改为 true 。
Modelhas bool IsChanged
型号有bool IsChanged

Try the same with @Html.TextBoxFor
尝试同样的 @Html.TextBoxFor
@Html.TextBoxFor(model => model.ExternalVenderNo, new { onchange = "OnChangeEvent()" })
<script type="text/javascript">
function OnChangeEvent(){
alert("value is changed");
@Model.IsChanged = true;
}
</script>
or leave Jquery to handle the change event
或让 Jquery 处理更改事件
@Html.EditorFor(model => model.ExternalVenderNo)
<script type="text/javascript">
$('#ExternalVenderNo').change(function(){
alert('Changed!');
@Model.IsChanged = true;
});
</script>

Try adding to attributes
尝试添加到属性
@Html.EditorFor(model => Model.Lengthofside1, new { htmlAttributes = new { onchange = "OnChangeEvent(this)", @class = "form -control text-right" } })
This worked for me.
这对我有用。
