You need to show the code you have for people to help you. No one here is going to write your complete assignment.

function colorSelector (colorCode) {
let randomNumber = Math.floor((Math.random() * 100));
if (randomNumber < 10) {
console.log("green");
}
else if (randomNumber >= 10 && randomNumber < 19) {
console.log("yellow");
}
else if (randomNumber > 19) {
console.log("blue");
}
return (randomNumber);
}
console.log(colorCode);
This is how far I got. Im confused what should be inside the function and what should we outside. Im also not sure if im using the return operator the right way.

Your code is quite confused, and confusing. You specify that the function takes an input parameter named colorCode, but you never refer to it in the function. Your if/else clauses include the variable condition which is never defined anywhere. Finally you return the randomNumber for no reason I can see.
- The function does not need an input parameter, unless you want to pass it a random number. Assuming yo do not, then generate the number as the first step.
- The if statements only need to be as follows
- 1: If the value is less than 10 set colorCode to "green"
- 2: Else If it is less than 50 set colorCode to "yellow" (we already know it is not less than 10)
- 3: Else set it to "blue" (it must be 50 or greater)
- return colorCode to the caller of the function.

So, you nearly there.
function colorSelector (colorCode) {
let randomNumber = Math.floor((Math.random() * 100));
if (randomNumber < 10) {
console.log("green");
}
else if (randomNumber >= 10 && randomNumber < 19) {
console.log("yellow");
}
else if (randomNumber > 19) {
console.log("blue");
}
return (randomNumber);
}
console.log(colorSelector(50));I got a warning that "colorCode" doesn't exist. And true, it doesn't. That makes it confusing, because there's two options. Let's forget them for a second. Try the code I gave you, vary the number. It writes to the console also.
Member 15708114 wrote: I know that I have to use the Math.floor and Math.random to create a random number and the if and return operators but I think im messing up the order. Please help anyone.
You creating a random number inside the function. You want to "pass" it to the function as an argument.
So you don't see where on thing starts and the other ends? It's called "scope". Ask your teacher. Once clear, ask to step.
It executes one line, shows result in debug. That way you see how the computer "steps" through your instructions.

else if (randomNumber >= 10 && randomNumber < 19) {
^^^^^^^^^^^^^^^^^^
We know it is >= 10 from the previous if statement.
else if (randomNumber > 19) {
And it this point it must be > 19, so all that is needed is a simple else clause.

That's the advanced course. I somehow think his teacher might have escaped that.
It's a beginner.

But that is nothing to do with programming, it is simple mathematical logic.

Correct. It got to do with education.

There was no requirement for a "random number"; the requirement was for a function that accepts a number.
And that function could be tested any number of ways; usually with a "console app" that accepts a number as input from the user and then uses that number in that function, and displaying the result.
if ( n < 10 ) {
else if ( n <= 50 ) {
} else {
}

Hello,
I am having a JSON Object as below in Node JS editor:
{"replyType":"queryDataRqst","requestId":169,"errCode" ,"options" ,"ccuSec":1657531129,"ccuNanosec":257000000,"replyData":[["IncidentStatusLine","\"machineId\":1111,\"incidentTidx\":101016,\"helpTidx\":101017,\"componentTidx\":100100,\"type\":2,\"state\":2,\"priority\":10,\"args\":{\"userData\":[{\"_d\":858993459,\"stringTidxValue\" ,\"longValue\":-634515298,\"realValue\" .0,\"nullValue\" },\"_d\":286331153,\"stringTidxValue\" ,\"longValue\" ,\"realValue\" .0,\"nullValue\" },\"_d\":286331153,\"stringTidxValue\" ,\"longValue\" ,\"realValue\" .0,\"nullValue\" },\"_d\":286331153,\"stringTidxValue\" ,\"longValue\" ,\"realValue\" .0,\"nullValue\" },\"_d\":286331153,\"stringTidxValue\" ,\"longValue\" ,\"realValue\" .0,\"nullValue\" },\"_d\":286331153,\"stringTidxValue\" ,\"longValue\" ,\"realValue\" .0,\"nullValue\" }]},\"text\":\"\",\"sequencenum\":287,\"timestamp\":1657522757472000000,\"wintimestamp\":133019963574720000,\"hashval\":-492839581,\"hideable\":false}"]]}
Now I need extract the value from the above JSON String as below:
{"userData":[{"_d":858993459,"stringTidxValue" ,"longValue":-634515298,"realValue" .0,"nullValue" },"_d":286331153,"stringTidxValue" ,"longValue" ,"realValue" .0,"nullValue" },"_d":286331153,"stringTidxValue" ,"longValue" ,"realValue" .0,"nullValue" },"_d":286331153,"stringTidxValue" ,"longValue" ,"realValue" .0,"nullValue" },"_d":286331153,"stringTidxValue" ,"longValue" ,"realValue" .0,"nullValue" },"_d":286331153,"stringTidxValue" ,"longValue" ,"realValue" .0,"nullValue" }]}
How to get this value using Node JS.
Thanks,

I'm using WebView2 to display data in my app. If I send a string literal it works fine. But if I send a value in a variable I get nothing.
This works:
wb.ExecuteScriptAsync("document.body.innerHTML=" & ChrW(39) & "HELLO" & ChrW(39))
This doesn't ("lStr" is my string variable):
wb.ExecuteScriptAsync("document.body.innerHTML=" & ChrW(39) & lStr & ChrW(39))
I assume I'm doing something wrong here. Any advice is appreciated.

That's going to depend on the content of your variable, which we can't see.
For example, if the variable contains a single quote or any newline characters, your script will end up with an "unterminated string literal" error.

Could possibly contain quotes but no newline chars. I was trying to give my old spell checker a facelift. I wanted to use the WebView2 for the error text ("Not In Dictionary"). It's one line from the text editor with the error highlighted. So I'd need to send it the error start/end positions plus tell it to scroll to that position. All easily done if I could figure out how to send it a value in a variable.

As I said, you'll need to ensure the value is properly encoded.
Assuming you're running .NET Framework 4.7.2 or later, .NET Core, or .NET 5+, then you can use the System.Text.Json package[^] to encode the string:
wb.ExecuteScriptAsync("document.body.innerHTML=" & System.Text.Json.JsonSerializer.Serialize(lStr)) For older frameworks, use the Json.NET[^] package.

Hi,
New here. Anyway I'm working on a project and I'm placing some text over some images. All is good with that.
However I only want to rotate the text 35 degrees but I can't figure how to do that in Javascript.
Here is how I'm displaying the text -
const ctxt = canvas.getContext('2d');
ctxt.fillStyle = 'red';
ctxt.font = '40px Brush Script MT';
ctxt.fillText('TEST',200,178);
Thanks.
|
|
|
|

The canvas uses a transformation matrix and it has a few functions for manipulating it.
Here is a 35-degree rotation:
const ctxt = canvas.getContext('2d');
ctxt.fillStyle = 'red';
ctxt.font = '40px Brush Script MT';
const tm = ctxt.measureText('TEST');
ctxt.translate(200 + tm.width / 2, 178);
ctxt.rotate(35 * 3.14159 / 180);
ctxt.translate(-(200 + tm.width / 2), -178);
ctxt.fillText('TEST',200,178);
ctxt.resetTransform();

An unformatted dump of your exception message, with no details of the code, posted in the wrong forum?
Sure, let us get right on helping you to fix that.

That looks like something you should start your investigation with.

What are the differences between Heap and Stack Memory in Java?

Yes, but you need to provide the details. You also need to post it in the Java forum; this one is for Javscript which is not the same thing. But do not expect anyone here to do all the work for you, even if you do offer ridiculous amounts of money.
