QUESTION
I was trying to get javascript to print the result of the "generateName" function at least 10 times when I press a button in the html, so i tried a loop inside the function that generates the names and but it didn't work then I separated the loop and wrote it in the function "namePrinter" and create the global variable "names" to store the results of the function "generateName" but I don't know what part of this whole process is wrong, I already reviewed other questions that were made in this forum but I didn't find an answer either

...ANSWER
Answered 2022-Apr-08 at 01:22innerHTML is not a function, it's a property. So, in the loop use text.innerHTML += name
However, if it's a </code> element, then you need to use <code>value</code> property instead:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>//this run the funtion that prints the names
document.getElementById("elvenFemButton").onclick = namePrinter;
document.getElementById("elvenFemButton2").onclick = namePrinter2;
//cutting characters function
function capFirst(string){
return string.charAt(10).toUpperCase() + string.slice(1);
}
//Randomizer
function getRandomInt (min,max){
return Math.floor(Math.random() * (max-min)) + min;

<pre class="snippet-code-html lang-html prettyprint-override"><code><textarea id="textArea">
generate names
generate different names
This however as you can see will print the same name 10 times, if you need generate 10 names and store them globally, than you'll need save them in the array instead.
P.S.
Unrelated, but elfLastName2[getRandomInt(0,elfLastName2.length +2)] is wrong, you can't get value from an index that is larger than length of the array (aka +2 is wrong)
QUESTION
The error I encountered is a bit strange. I build a music player on my website, and every functions of this music player I build works fine.
Let me show you the error first,
...ANSWER
Answered 2022-Mar-29 at 03:26I finally found the mistake I made. It's rather a stupid one.
Basically, the problem is not in the code I posted. In my onTimeUpdate function, I have setIndex(index+1) if time runs out for the song. Meanwhile, in onEnded function, I have another setIndex(index + 1), so index + 1 is trigger twice, which causes a looping problem, resulting in Javascript not finding the right path for my album cover.
I think I found a better logic to play the next song, without using the onEnded prop.
Here is my solution:
QUESTION
I am practicing using loops to manipulate with data on my index.html. I am currently trying to filter an input text field where it will show data while the user types and hide the rest of the data.
...ANSWER
Answered 2022-Jan-26 at 20:32You can call forEach on the result of querySelectorAll. Just loop over each
.hidden instead of modifying the DOM. Also, the string object has an includes method.
QUESTION
I just entered react native about a week ago and I just stumbled on this problem.
Every time I connect the navigation stack/drawer to my home app.js and then I run the expo app it shutdowns unexpectedly. Sometimes it shows an error but for less than a second then closes. But most times it never shows an error before closing.
I was able to capture an error but I'm not sure if it was the error that briefly shows. This was the error
...ANSWER
Answered 2022-Jan-18 at 17:03I found out that the problem came from me installing the drawer navigation and stack navigation together. Also I came from the netninja youtube channel. Uninstalling that fix my problem and following the updated way to install it.
QUESTION
I am using the checksum calculator from: https://github.com/Vi1i/OcarinaChecksumChecker
I downloaded the ocarina.h and checksumCalc.c files and was able to compile them using gcc checksumCalc.c in WSL for Windows (Debian Linux shell in Windows 10). It then outputs the file "a.out" which I am able to run using ./a.out "THE LEGEND OF ZELDA.sra" 0020 and which calculates the correct checksum for my Legend of Zelda save file that matches what I see in my hex editor.
Then I decided to play around and try compiling it using Windows. I've set up my Powershell so I can compile C programs simply using "cl" in Powershell. First, I tried doing cl checksumCalc.c and I got the following errors:
checksumCalc.c(49): error C2065: 'ushort': undeclared identifier
checksumCalc.c(49): error C2146: syntax error: missing ')' before identifier 'data'
checksumCalc.c(49): error C2059: syntax error: ')'
After Googling the first error, I changed "ushort" in the checksumCalc.c file to USHORT, and added #include at the top of the file. I tried compiling again and it actually compiled. However, when I try running the resulting exe in Windows, it gives an incorrect checksum. I used the same syntax as the a.out file, but replaced a.out with checksumCalc.exe. checksumCalc.exe "THE LEGEND OF ZELDA.sra" 0020
Does anyone have an idea of why the program is giving me a completely different result in Windows versus Linux? Here is a direct link to the checksumCalc.c code: https://github.com/Vi1i/OcarinaChecksumChecker/blob/master/checksumCalc.c
As mentioned above, the only thing I changed when trying in Windows was I added #include , and I made the ushort at the bottom all caps. I was hoping someone that understands the quirks of C programming and the differences between compiling in Windows and Linux could help me understand what might be going wrong.
For the record, I can just as easily accomplish what I'm trying to do by just getting the checksum from the Linux shell but I just want to understand what might be going on from a learning perspective. I'm a C noob, and to me I figured C was C, but apparently there must be commands that are exclusive to Linux/Windows where the code needs to be adapted to work properly.
...ANSWER
Answered 2022-Jan-03 at 19:37Got this working properly thanks to this tip by user Maxim Sagaydachny in the comments:
replace FILE *file = fopen(argv[1], "r"); with FILE *file = fopen(argv[1], "rb");
It looks like something to do with the way Windows was reading the file as a text file, the "b" seems to indicate that the file should be read as binary. Now the Windows program is generating the correct checksum.
Thanks to Maxim Sagaydachny for this tip which ended up solving the issue. Also, thank you Joseph Sible-Reinstate Monica for the suggestions!
QUESTION
I'm not a developer. I've been however tasked with coming up with a solution for a small project at work with jQuery and I have no clue where to begin. Here's my codepen: https://codepen.io/axo1/pen/mdBLRjL
What I need to is this (all graphics and texts are placeholders):
What I managed to achieve
- Image
item1is supposed to be the first visible, - Hovering on the buttons below the graphic changes which image is displayed,
What I don't know how to achieve
- The buttons below should be clickable. Clicking on a button changes the "active" graphic above. For example: if I click on the
Second itembutton, theitem2image will be displayed even after I unhover the button, and so forth.
Any tips of what I should look into?
Unfortunately jQuery is heavily preferred here.

I kept your style - I think it can be shortened to be more DRY
QUESTION
ANSWER
Answered 2021-Oct-15 at 14:50Some issues on your code...
- you need an onload event to make sure the image has loaded before you can do anything
- you need
sprites.crossOrigin="anonymous"or you will get a Tainted canvas error - your logic was not clear, you had a double loop but only one toDataURL outside the loop

QUESTION
The use case is this: each user can create their own games, and keep track in which country they played a game.
I would like to create one query where I can get a list of all games for that user and in which country that game was played. I am only interested in the country id.
I have 4 tables: users, games, countries and a games_countries_xref table.
...ANSWER
Answered 2021-Oct-13 at 02:53You are on the right track with ARRAY_AGG, but just a little over aggressive with the joins. You just need a simple join (1 left, 1 inner) on the 3 tables
QUESTION
I need to obtain the redirect URL from a request, and I understand the way to do this is within willPerformHTTPRedirection.
When I try my code with a URL like http://gmail.com, the redirect request IS noticed and processed through willPerformHTTPRedirection but other URLs, the redirect is processed but willPerformHTTPRedirection IS NOT called.
For example, the following URL https://www.pricecharting.com/search-products?q=045496590420&type=prices does not call willPerformHTTPRedirection. If I turn off automatic redirects in Postman I can see the redirect URL in the Location header. How can I obtain this same info with URLSession?
ANSWER
Answered 2021-Sep-22 at 00:12Turns out the code is correct and working as desired. The code came prior to the call.
I am converting barcode to UPC, and i was mistakenly converting it to an integer. Integers dont start with 0 and UPC does. Keeping UPC as a string kept the 0.
Given this, the following URL works as it should because its status 307:
