mvc3 maxLength input
提问by CodeNoob
this may be kind of general but i want to limit the number of character inpit in an editorfor field.
这可能有点笼统，但我想限制 editorfor 字段中输入的字符数。
@html.EditorFor(m=>m.id,new {@maxlength="10"})
This does not seem to work.
这似乎不起作用。

Try changing it to
尝试将其更改为
@Html.TextBoxFor(m=> m.id, new { maxlength="10" });
EditorFor uses the templates, which you can override yourself. I don't think they take into account the attributes you pass in like this. The TextBoxFox<> generates it in code, and should work fine.
EditorFor 使用模板，您可以自己覆盖这些模板。我不认为他们会考虑你这样传入的属性。TextBoxFox<> 在代码中生成它，应该可以正常工作。

I was able to get it working in IE11 using the EditorFor and using multiple attributes.
我能够使用 EditorFor 并使用多个属性使其在 IE11 中工作。
@Html.EditorFor(model => model.CourseNumber, new { htmlAttributes = new { @style = "width:100px", @maxlength="10" } })

In MVC3, this is better:
在MVC3中，这更好：
[StringLength(10, ErrorMessage = "Name cannot be longer than 10 characters.")]
public string Name { get; set; }
Specifies the minimum and maximum length of characters that are allowed in a data field. as in this https://stackoverflow.com/a/6802739/2127493
