How to Remove Client-Side Validation on a textboxfor for multiple emails?

334 Views Asked by C Murphy At 21 October 2024 at 11:07

I am creating an MVC application in which I will have an input field for a list of emails. In order to do so, I added multiple in order to allow for the user to enter a comma separated list of emails. By doing it this way, I'm able to have input controls to check for the email(s) to be properly formatted ("[email protected]").

The problem is that when I test this, it automatically adds class="input-validation-error" (even if I set the @class="" prior) and will not allow me to post due to an invalid input, as a result. Is there any way to allow for this, or is my only option to make it an Email string property and parse it by commas into the EmailList property in the controller?

(Here is my code):

View:

@Html.TextBoxFor(model => model.EmailList, new { type = "email", placeholder 
= "[email protected] (',' Delimited)", title = "Make sure your email(s) are 
formatted appropriately (and comma separated).", multiple = "" })

Model:

public List<string> EmailList { get; set; }

UPDATE:

I should also add that I am performing json serialization on post, so It needs to be in the form of a list. Ideally, I would be able to use the multiple for the input of type email tag, since it would allow for the necessary input controls that I would need without making me take it as a string and writing it to a list.

add a js file hopefully u use jQuery

$(document).ready(function () {
    $("#EmailList").removeClass("input-validation-error");

});

After Reviewing kblau's answer, I realized that was partially the reason. The other issue that I was running into (where MVC was stepping over any of my manually entered client-side validation) was the result of the unobtrusive validation:

<script src="~/Scripts/jquery.validate.unobtrusive.min.js"></script>

After commenting this out, it allowed for me to have the input write to a string Email which I would then assign to a list of strings EmailList in the controller. This ended up working for me.
