HTML required readonly input in form

Question

I'm making a form. And on one input tag is an OnClick event handler, which is opening a popup, where you can choose some stuff, and then it autofills the input tag.

That input tag is also readonly, so only right data will be entered.

This is the code of the input tag:

<input type="text" name="formAfterRederict" id="formAfterRederict" size="50" required readonly="readonly" OnClick="choose_le_page();"  />

But the required attribute isn't working in Chrome. But the field is required.

Does anybody know how I can make it work?

Solution 1

I had same requirement as yours and I figured out an easy way to do this. If you want a "readonly" field to be "required" also (which is not supported by basic HTML), and you feel too lazy to add custom validation, then just make the field read only using jQuery this way:

form the suggestions in comments

<input type="text" class="readonly" autocomplete="off" required />

<script>
    $(".readonly").on('keydown paste focus mousedown', function(e){
        if(e.keyCode != 9) // ignore tab
            e.preventDefault();
    });
</script>

ORIGINAL

<input type="text" class="readonly" required />

<script>
    $(".readonly").keydown(function(e){
        e.preventDefault();
    });
</script>

Solution 2

readonly fields cannot have the required attribute, as it's generally assumed that they will already hold some value.

Solution 3

Remove readonly and use function

<input type="text" name="name" id="id" required onkeypress="return false;" />

It works as you want.

Solution 4

This is by design. According to the official HTML5 standard drafts, "if the readonly attribute is specified on an input element, the element is barred from constraint validation." (E.g. its values won't be checked.)

Solution 5

Required and readonly don't work together.

But readonly can be replaced with following construction:

     <input     type="text"
                onkeydown="return false;"
                style="caret-color: transparent !important;"                   
                required>

1) onkeydown will stop manipulation with data

2) style="caret-color: transparent !important;" will hide cursor.

3) you can add style="pointer-events: none;" if you don't have any events on your input, but it was not my case, because I used a Month Picker. My Month picker is showing a dialog on click.
