I have a problem to disable an `<input>` element with JavaScript/jQuery on Internet explorer.

I tried

```
$('input[name="chooseNeedsubmit"]').prop('disabled', true);

```

and

```
$('input[name="chooseNeedsubmit"]').disable(true);

```

this is the html code of the btn:

```
<input class="action-form" type="submit" name="chooseNeedsubmit" value="Envoyer votre demande">

```

Any help?
