I am trying to create an image of both my google chart and a table that is below it, all in one image. The problem is when I create the image using HTML2Canvas the table shows up but the area of the chart is empty.

This is what it looks like:

The empty area above should show a bar chart but it is completely empty.

My code:

I want to create a histogram that is a dictionary showing for each wordlength how many words with that length are in the input text. So far I have managed to create a dictionary with all possible wordlengths, but I can't seem to manage to update the dictionary. I am stuck with the error: Full Python Traceback:

The page I am working on shows four tabs. I have two questions:

Question 1: When viewing page with Explorer, the selected tab (via CSS focus) shows a black background. However, when viewing the page with Edge, this does not seem to work. What do I need to change?

Question 2: Initially (with Explorer) the pre-selected tab (which is the first tab) does not show this black background. This black background only appears after clicking on one of the tabs but not after reloading the page. What changes do I need to have the pre-selected tab show the black background already immediately after page reload?

I have a login form, which has to be executed through ajax to PHP. From PHP he has to send a message back to ajax, and Ajax has to display the message. The problem is, that some of the messages doesn't display. It'll give the following error:

Conditional Statements:

As I said, some statements does work and some doesn't

• Check if form is empty. This doesn't work. What I've tried: I opened the login.php via URL. So, the form was empty. It returned: {"msg":"formleeg"} as it has to be. But still, it doesn't work.
• If the form isn't empty: Check if the username is correct. This doesn't work.
• Check if the password is correct. This works correctly.
• Last statement, the else works perfect.

My Codes:

The form:

The past day's I've been trying to return a true or false boolean to Ajax.

The Process: Someone submit's a form > Send to a PHP file > From PHP, check everything is correct. If yes, return true and echo 'correct'. > Output the result. In this case, it'll have to echo correct. And check if it's true or false.

The problem is, it will always return a false. Even when everything is correct. So when my login is correct, it will return a correct, as I expect. But it won't return a true.

My form:

I have a list where questions are shown, each question has three possible answers.

They are: ok, fout and nvt only with fout I want a div to slide down in which I can add some stuff.

Basically the answers are : good, wrong and not applicable. When an answer is wrong, I want to be able to add into an input field why it was wrong.

So beneath that answer I need a div to slidedown only when fout is clicked, and slide up again when one of the other two options are clicked.

How can I do this?

This is my HTML currently:

I am making a panel with PHP. It contains a login script. It's working good, just what I expect. The next step is: Echo the username.

With $_POST you can echo the username what the person has typed. So, just like: Welcome, $username.

The problem now is, that I can't echo the $_POST. It's not possible because you will redirect to another page. My question is: How can I echo a username.

My login script:

I've created a page on Codepen to be later added to my Ruby on Rails app ( https://codepen.io/salman15/pen/evQVLV ), where all the code works fine.

After creating the page I tried adding the page to my Ruby on Rails app with spree (which is running on Cloud 9 https://consulegem-salman15.c9users.io/ "server might not be offline at the time that you read this"). I've done this in the following manner:

Step 1: Added the html code to the index.html.erb

Step 2: Added the CSS CDN to the _head.html.erb

Step 3: Downloaded all the JavaScript libraries and added them in the following folder path -> app -> assets -> javascripts -> frontend -> store

step 4: added the following line of code to my all.js file (inside in the frontend folder)

I have an array which holds some articles of a website. The problem is: when the same article is in 2 different categories it only shows 1. In this example the categories are 'Service' and 'Sales'.

If the article is duplicate and the category is 'Sales' I want 1 of them to change to 'Service' and vice versa.

The array I got now(3 & 4 as duplicates and 7 & 8):
