如何将EditorFor框中的DateTime对象默认为今天的日期？

Question

I am trying to make the EditorFor bootstrap box default to today's date and be read-only, so that when the form is submitted, it will be today's date without the user having to manually enter it.

I have tried some methods, but the value just remains as "mm/dd/yyyy". I would like for it to say "09/05/2019" if they were submitting it today.

Here is the EditorFor box in the view

            <div class="form-group">
                @Html.LabelFor(model => model.postDate, htmlAttributes: new { 
                @class = "control-label col-md-2" })
                <div class="col-md-10">
                    @Html.EditorFor(model => model.postDate, new { htmlAttributes = new { @value = DateTime.Today.ToString("mm/dd/yyyy"), @readonly = "readonly" } })
                    @Html.ValidationMessageFor(model => model.postDate, "", new { @class = "text-danger" })
                </div>
            </div>

And here is the attribute in the model

    [DataType(DataType.Date)]
    public DateTime postDate { get; set; }

How can I get this to just be a box that shows today's date in the preferred format?

Answer 1

Try this:

@Html.TextBoxFor(m => m.postDate, new { @Value = DateTime.Today.ToString("MM/dd/yyyy"), @readonly = "readonly" })

Notice:

• The name of the method
• The MM in the format
• Capitalization of the @Value parameter

A different method is necessary because if you look at the signature of EditorFor , it does not allow passing of HTML attributes.

The MM is the correct way of displaying the two digit month (as opposed to minutes).

Capitalization seems necessary for @Value . A lower case @value does not work for some reason.
