magento2 – (Magento Framework Config Dom ValidationException): "referenceBlock" element, attribute "class": the attribute "class" is not allowed

I have this problem and I can not locate the problem:

1 exception (s): Exception # 0 (Magento  Framework  Config  Dom  ValidationException): The "referenceBlock" element, attribute "class": the attribute & # 39; class & # 39; is not allowed. Line: 1124

This problem occurs as a logged-on client when I try to access the invoice for a test command.

Here is what I tried to do to solve the problem by following many topics on this forum:

  • configuration: di: compile
  • Delete the contents of / pub / static / frontend
  • Deploy static content

Nothing works.

Note that I looked in my XML for a referenceBlock with a class attribute, but found nothing. Maybe I'm not looking at the right place?

Directories scanned to find the error:
– / app / code
– / app / design

Can any one explain me how to locate this error more precisely? Or help me solve it?

Magento version 2.3.1

Thank you in advance.

javascript – Wait for an item to exist in DOM before clicking on it

Here's the problem: a script injects HTML5 elements (actually a button with the #the button ID) to the current DOM.

But this is a third party script and I have no control over when it will be injected to the page.
I need to automatically click this button when the button is injected into the DOM. Here is my solution until now.

It really works but I'm not sure about the quality of this code. My first assumption is that I can use the clearTimeout () method. Is there anything else I have to do?


Here is a simulated jsFiddle from the whole process: https://jsfiddle.net/qxpcj3wm/

Intersite script (based on the DOM)?

I'm doing this challenge and I've come across a very difficult level that I think concerns the XSS DOM.

I know it because I do not get any response from the server side and everything I insert will not be reflected because of a sudden leak.

Here is the sample source code of the page:

link: https: www.example.com/

 

When I open this link

https://site.example.com/ac/primary/js/en-US/base-responsive-v2-footer.a9d4b9536378c2666557.js

I find this

a (e)} document.cookie = "ua = 531227642bc86f3b5fd7103a0c0b4fd6; path = /; max-age = 31536000"; if (null == window.location.host.match (/.* etsy  .com $ /)) for (var s = 0; s <document.forms.length; s ++); $ ("")} (function () {var e = function

How can I exploit this?

html – counter with javascript in the DOM at the push of a button

Hello I have a problem with a cash register application. When you press a button representing a product in the store, a card must be created in a container that must contain the quantity of products collected from that respective product. my problem is that first of all everything goes in the card with 1 of quantity but if I preciono still the same button so that there are now two loaded products. I have tried to do it but I can not and I would like them to help me do it. to be able to move forward with the other features of my program.

It's the first one I do, I'm very excited, but it's beyond me. I hope and you can understand me and help me.
greetings

javascript – Targeting a single event in the DOM

In the image below, I want to open a modal when a user clicks anywhere in the yellow block, including clicking the white "+" sign. The problem is that the click event occurs on a different target depending on whether the user clicks the yellow part or the white sign "+".

In my JavaScript code, I have handled it like this until now, but I wonder if there is a shorter and better way to do it that does not require the II operator:

openModal (e) function
if (e.target.classList.contains ('project-box__picture-box') || e.target.classList.contains ('project-box__icon')) {
modalEl.classList.add (& # 39; open & # 39;);
}
}

DOM Events

angular – Styling dom elements powered by ngfor

Context: So I'm getting data from the background that I'm storing in a table on my angular front end. Now, I try to display each of these elements (which are products) on the model. What I'm essentially trying to achieve are products on a page that users can browse.

Problem: The problem is that ngfor simply draws elements one after the other following a vertical line on the model. What I want is to be able to apply general style settings so that items move from the top left of the page to the top right in a row from 1 to X number of items depending on the width of the display window, and then continue as such on the following items. the lines until there is none left in the original chart.

I would be grateful if anyone could point me in the direction from which I could reach the desired result.

javascript – access to the dom – is there a reader equivalent to Renderer2?

I have an angular 5.x application that has to process the payments of an iframe – the reminder URL is not part of the angular project. In fact, many of them could change depending on the context.

Some of them are quite modern and do not pose a problem. Others respond to a POST and return raw JSON. In this case, I have to get the data directly from the document in the iframe before closing it.

this requires (finally I hope not) access to:
elementRef.nativeElementand from there .contentDocument or contentWindow.document, reading the text from there (even if the answer is a raw JSON, it is loaded into an iframe html, so it gets a "free" document that I have to decouple manually).

So I do that. It works. But this is not testable. Since I do not read or write, I imagine Renderer2 can help me. How can I get the innerText of an element in an iframe without touching the DOM?
