How to make the quill editor field required? The editor gets rendered into a div, but it isn't clear if there is a way to make the field/editor required when the form submits.
As you wrote, Quill works with a div and not with a form element so it can't help you with form validation.
You'll need to check manually if the editor's content is empty, prevent the user from submitting the form and show a message that this field is required.
You can copy quill contents to a hidden input element before submitting the form as shown in this example.
A custom form control is also a good way to go. You can try to workaround with Quill's event handler and getting the value of the form.
Then a custom form validator is also possible.
Check : https://blog.thoughtram.io/angular/2016/07/27/custom-form-controls-in-angular-2.html
I've been trying to work around exactly this problem too today, using Python for back-end and a hidden form-field (name='editor') to get the value from the quill container to the back-end. Ended up with not actually really a validator but working about the same:
if request.form['editor'] == '\"<p><br></p>\"':
flash("You cannot send in empty posts!")
return redirect(CURRENT PAGE)
else:
CODE EXECUTED IF EDITOR IS NOT EMPTY
Not sure what you're doing with the input on the editor or whether you're even using Python for backend but I hope this helps. "<p><br></p>" is what the console told me the standard input on empty submission was when getting the information out of the editor.
Good luck!
const yourText = '<div><br></div>';
const htmlTagsToRemove = ['<div>', '</div>', '<br>'];
function removeHtmlTags(data) {
let text = data;
htmlTagsToRemove.forEach(it => {
text = text.replace(it, '');
});
return text;
}
const newText = removeHtmlTags(yourText);
console.log(newText);

I'm trying to validate a simple form using react-hook-form. I'm handling the validation part fine, the only problem I have at the moment is that I want to change the background color of the input field and at the same time add a little popup text if the field is not validated. I'm able to do the text popup part pretty easily, but can't seem to find a way to change the background color of the input. I was just wondering how it is possible to have a P tag inside the {errors} method and also to set a certain state in the same method.
for example, If I want only the text popup, I can use the following :
<input name="name" {...register("name",{required:true}}/>
{errors.name && <p>Type a name</p>}
But how can I handle setting a state inside that method? for example, if I have a state :
const [background, setBackground] = useState(false);
How should I approach using the setBackground, something similar to this :
{errors.name && <p>Type a name</p> && {setBackground(true)}}
The following doesn't work, console says I'm rendering too much, but I'm curious If there's a solution similar to that. Would appreciate any advice!
Here's the codesandbox link to better understand what I'm trying to achieve :
https://codesandbox.io/s/aged-lake-ieyctq?file=/src/App.js
You can achieve it via using the useEffect hook from react that will run your setBackground function if an error on the name field was detected:
useEffect(() => {
if (errors.name) {
setBackground(true); // sets background in case there was an error
} else {
setBackground(false); // unsets background in case there is no error
}
}, [errors.name]);
See it working on your forked sandbox:

Basic problem is, when user tabs in a specific text input on a form, prefilled "+36" gets selected. I'd like to somehow put the cursor right after it (after the +36), instead of selecting the whole word. I've been thinking about disabling text selection of text inputs but no result yet. Googled a lot for it but couldnt find anything but disabling text selection on web pages, which is not really related. How could I solve this problem?
If you are using Jquery, you can try something like this on document ready
$(document).ready(function() {
$("input").focus(function() {
var input = this;
setTimeout(function() {
input.selectionStart = input.selectionEnd;
}, 1);
});
});

In your form element put autocomplete attribute like below
<form method="post" action="/form" autocomplete="off">
</form>
I have the following code:
<form class="form"
data-ng-submit="modalSubmit(modal.data)"
id="modal-body"
name="modalForm"
novalidate>
This works and when I click on a button of type submit then the modalSubmit function is called.
However I would like to do this in my controller:
$scope.modalForm.$setPristine();
But it gives an error saying:
has no method '$setPristine'
How I can I set the form to pristine? I did try adding data-ng-form="modalForm" but then I get
a message saying something to the effect of duplicate directive names.
I tried changing the form element to a DIV but then the clicking on the submit button does not call
the function
Here's an example (modified from another user) that shows what I am trying to do which is set values to pristine:
plnkr.co/edit/LNanJdAggMLIgxii0cfv?p=preview
You're not doing anything wrong there, only problem is you're referencing an old version of angular in which $setPristine() was not a feature. $setPristine() was added in 1.1.+, so reference a newer version of angular and you're good to go. See it working in this plunk, using 1.2.+.
If you can't upgrade, then a dirty workaround would be to loop through all inputs in the form and set their $dirty and $pristine values manually:
$scope.mp = function() {
$scope.mainForm.$pristine=true;//clean main form
$scope.mainForm.$dirty=false;
angular.forEach($scope.mainForm,function(input){//clean all input controls
if (input !== undefined && input.$dirty !== undefined) {
input.$dirty=false;
input.$pristine=true;
}
});
}
First, your version of angular was old, 1.2.12 is the latest stable on the CDN. But even it wouldn't allow $setPristine because of the HTML5 validation that was going on.
The biggest problem was you used required on the fields instead of ng-required. The browser was doing the form validation for you instead of angular. You could also add the novalidate attribute to the form tag.
http://plnkr.co/edit/l1mUCceSFMFFZWgGgL6u?p=preview
it has already been implemented in this link you can use it this was as it has been demonstrated in the plnkr link.
As you can see from the above description, $setPristine only changes the state of the form (and thereby resets the css applied to each control in the form).
If you want to clear the values of each control, then you need to do for each in code.
I use https://github.com/CakeDC/TinyMCE to download plugin and did follow all the step to integrate on my cakePHP project. so right now, all the textarea was successfully changed to tinyMCE editor
But when click "SUBMIT" to submit my form, page cannot submit and post data. Without loading editor my form can submit and post data.
Is any jquery problem ? please advise me.
thank you.
Bootsrab.php
CakePlugin::load('TinyMCE');
Configure::write('TinyMCE.editorOptions', array('width' => '500px','height'=>'250px' ));
Controller:
public $helpers=array('Html','Form','TinyMCE.TinyMCE');
View:
$this->TinyMCE->editor(array('theme' => 'advanced', 'mode' => 'textareas'));
echo $this->Form->input('user_requirements',array('required'=>true) );
Layout : default
loding js file:
echo $this->Html->script(array('ddsmoothmenu','jquery-1.7.1.min','jquery-ui-1.8.17.custom.min'));
You've set the field to be required, so the problem you are experiencing is probably the browser based form validation.
The problem is that the validation applies before TinyMCE injects the contents into the textarea, and so the validation will always fail as the textarea is empty. This is a very long known "bug" btw:
http://www.tinymce.com/develop/bugtracker_view.php?id=4768
http://www.tinymce.com/develop/bugtracker_view.php?id=5671
In Firefox you might notice a validation bubble that appears "behind" the browser in the bottom left corner of the screen, and in Chrome for example it would throw the following error: "An invalid form control with name='...' is not focusable".
The quick and dirty fix would be to set required to false. In order to keep the required class on the generated container div you would have to set this manually using the div option:
'div' => array('class' => 'input text required')
It's also possible to disable browser validation completely by defining the novalidate attribute on the form:
$this->Form->create('ModelName', array('novalidate' => true));
or using the formnovalidate attribute on the submit button:
$this->Form->submit('Submit', array('formnovalidate' => true));
Theoretically it would also be possible to listen to the invalid event and display custom validation bubbles, but the problem here is that the browser behavior is not consistent, ie in Chrome it's not possible to validate invisible (using display or visibility) fields. Also the content would still be missing in the textarea field.
What seems to work is using opacity to hide the field, that way one could position the textarea under the editor, and the validation bubble would be displayed correctly. However that would also require to inject the editor contents in the textarea manually when pressing Enter and when clicking the submit button (or probably even simpler using proper editor change events). I'll see if I can come up with an example for this later on.
Update: I've implemented a fix/workaround in form of a TinyMCE 4.x plugin, as this was bugging me in some of my own applications too, see https://github.com/ndm2/tinymce-validatable
I have a PDF form and I need to prevent printing this PDF form, if its fields are blank.
To modify my form i user Adobe LiveCycle Designer ES3.
About how can this be done is written here: http://forms.stefcameron.com/2008/04/13/prevent-printing-pdf-forms-in-acrobat-8/
The only thing i need more than in this article - is to suppress message "Printing Cancelled", or overide it with another text.
So, if somebody knows how can it be done, please help me.
Do you a print button on the form which is being clicked to print the form ?
If you do, then there is a way to suppress the printing. Otherwise, I don't know of any way of solving your issue.
If you do have a print button, add the following code to the click event of the button:
var result = form1.MainPage.execValidate();
if(result==false){
xfa.host.messageBox("Please ensure that all validations are complete before printing.");
}
else{
xfa.host.print(1, "0", (xfa.host.numPages -1).toString(), 0, 0, 0, 0, 0);
}
Where "form1" is the rootnode of the form and "MainPage" is the page which contains all the subforms in your form. the exeValidate() method fires all the validation messages in the form and returns a true if the all validations pass the test. Otherwise it returns false.
Pleaselet me know if you have any other questions.
Thanks,
Armaghan.
Set your event picker to "PrePrint", Add your validation script.
Enter : xfa.event.cancelAction = (true) at the end of your "If" statement.
