QUESTION
Denizens of stack overflow, I call upon your help and grand wisdom.
Problem: driver print is printing pretty much all that I need it to, but the first row also prints the entirety of the information as well in one long line. I've noticed the format doesn't stay for copy/pasting my console putput so I'll attempt to describe it. It prints out, neatly enough, a formatted table with the info I need. It's just that the top row duplicates the info as well. It appears to be the exact same print, just with no new lines
I have this shopping cart application. All is done and now I'm working on the toString formatting for the receipt looking printout in console. As this encompasses 7 or so different classes I won't post all of the code, but just the cart, driver, and parent class as it's my best guess that's where the problem is originating. If more is needed please let me know and I can post what I have.

QUESTION
I am new to Java script and in an assignment I am directed to create 2 JS
files and then display data dynamically in HTML. One JS file data.js
file have an array of objects
(lets say table of items) and another JS file has function which loads those items
, create HTML elements and display items (catalog) on HTML page.
I have found relevant post [here](How do I include a JavaScript file in another JavaScript file? cript-file-in-another-java script-file) . But I am still unable to understand that how to access display data from 1 JS file
while loadfunction()
is located into another JS file.
Also I don't know how to assign an External CSS class to this dynamically created element.In boutique.js the syntax is
itemName.classList.add("addCSS");` Please help me in this regard. Thank you.
ANSWER
Answered 2020-Jun-09 at 09:27The post, you mentioned explains it well. In order to get data from a different javascript file, you can use the require()
function.
In your data.js you need to define the catalog object as a part of the module export like this:

- and
not wrapping in css grid layout
I'm trying to understand the CSS grid layout and I love every bit of it so far! However, I can't seem to get the code blow to work.
When the nav sidebar fills the whole width, I want the paragraph to the right to break down beneath the navigation. I know how I'd do it with flexbox and media queries (flex-direction: row vs column) but I don't really get how one does it with CSS grid. Can you help me?
...ANSWER
Answered 2020-Apr-01 at 07:11I think you can take a look at how it's solved in bootstrap. The sidebar does not expand at all. See what they consist of and when to use classes:
container This class should have a dunamic width depending on the @mediaquery settings.
row you also need to do something to separate the lines. Read how the row class works.
In general, the bootstrap documentation itself refers to the page: https://css-tricks.com/snippets/css/a-guide-to-flexbox/#flexbox-background
There you have this topic explained on pure CSS - and that's probably what you mean...

QUESTION
I couldn't get certain JSON Value using TJSONObject
, i get error of Access violation at address xxxxxxxxx
.
I have a problem getting the desired value using it's key name from JSON File,
i'm currently using TRESTClient
, TRESTRequest
, TRESTResponse
to get JSON data from the web, i used same JSON URL with Javascript and works fine, but in C++ Builder it doesn't, it simply showing me an error of Access violation at address xxxxxxxxx blablabla
, that happens when i try get certain JSON value using it's name like for EX: "name": "sparky"
, but when i get full JSON File it succeeds without errors.
Code:
...ANSWER
Answered 2019-Apr-10 at 16:00The JSON you have shown is an ARRAY OF OBJECTS rather than a SINGLE OBJECT, like your code assumes it is. So TJSONObject::ParseJSONValue()
would return a TJSONArray
instead of a TJSONObject
, and as such there is no way that your assertion in comments that the "JSONObject is valid" can be true since dynamic_cast
would fail and return NULL, which your code is not checking for. You did not show the FULL error message, but if it says "read of address 00000000", that is a good indication that a NULL pointer is being accessed.
Also, TJSONObject::Get()
is deprecated. To retrieve a value by name, use TJSONObject::GetValue()
instead.
Also, TRESTResponse
can parse the JSON for you, if you use the TRESTResponse::JSONValue
property instead of the TRESTResponse::JSONText
property.
Also, you are leaking the TJSONObject
that you allocate, if your code is compiled using one of the non-ARC-based C++ compilers.
With that said, try this:

I am trying to complete the tutorial here: tutorial official Docker
Here is my output for docker images
ANSWER
Answered 2018-Sep-22 at 07:09Ok, so the creator of the tutorial forgot to mention we have to tag the image first with docker tag {image ID number} yourhubusername/{name_of_your_choice]:firsttry
where :firsttry
is a tag (I'll post photos below).
Here is the terminal output from the above tagging and then docker push
