This is my first interaction ever with JavaScript so pls bear with me on this.
I want to dynamically create a multiline variable (string). The way it is going to be created based on some conditionals, something like
if (${{ inputs.a_gha_input }}) {
add_this_line_to_a_multiline_js_var("Hello")
}
if (${{ inputs.another_gha_input }}) {
add_this_line_to_a_multiline_js_var("World")
}
I would like my end result to be something like this
Hello
World
(in case both conditions are true of course)
Thanks
Just use carriage return symbols in your multiline string. Your function add_this_line_to_a_multiline_js_var(line) may look something like this:
let multilineString = '';
function addLineToMultilineString(line) {
multilineString += (line + '\n');
}

How to Display each variable of for loop in a div tag using javascript? Using innerHTML i am only able to display the last variable of for loop
You can do as follows, but it is better to use lists.
Lists: https://developer.mozilla.org/pt-BR/docs/Web/HTML/Element/ul
const myDreams = ["Fly", "Be rich", "Go to the moon"];
const myDreamsDiv = document.querySelector("#myDreams");
//The secret here is to add a breakline(<br>) between each word.
myDreams.forEach(dream => myDreamsDiv.innerHTML += (dream + "<br>"));
<div id="myDreams"></div>

I am a beginner to javascript and I am confused on how to split a string which is separated by line breaks, into a 2d array. Here is the string. The numbers represent something that I need to make the code function, so excuse that:

Hey buddy I'm also new but I actually have an idea. You can try this:
a.split("\n");

I have tried everything I can think of to get the data but cannot figure this out.
The data is in a structure like this:
[{"code":1000,"day":"Sunny","night":"Clear","icon":113,"languages":
[{"lang_name":"Arabic","lang_iso":"ar","day_text":"مشمس","night_text":"صافي"}]
}]
I've tried looping, using key:value using the dot notation and bracket notation and cannot get the info.
I'm trying to get to the "languages" so I can parse them for the weather.
var arr = [{"code":1000,"day":"Sunny","night":"Clear","icon":113,"languages":
[{"lang_name":"Arabic","lang_iso":"ar","day_text":"مشمس","night_text":"صافي"}]
}]
arr.forEach(function(obj){ //loop array
obj.languages.forEach(function(language) { //loop languages
console.log(language); //language object
console.log(language.lang_name); //language property
});
});

Where should I store message types javascript function is returning? I can just return string messages, but it seems like a bad idea. Are there any best practices?
For example in this kind of function (of course real functions make more sense then this)
function isFooValid(foo){
if(foo.length < 4){
return "TOO_SHORT";
} else if(foo.length >100) {
return "TOO_LONG";
} else if(foo.charAt(1) == 'A'){
return "THERE_SHOULD_NOT_BE_SECOND_CHARACTER_A";
}
}
You can create a variable for that. For example you can have:
myMessages ={
"secondChar": "THERE_SHOULD_NOT_BE_SECOND_CHARACTER_A",
"tooShort": "TOO_SHORT"
}
Then you can retrieve them as myMessages.tooShort, for example.
Even, if you want to have something similar to the string resources in android, you can store all the strings in a json file. If you load it before you js script, you are going to have the myMessages var available.

The following Code should output:
txt1txt2txt3...
var result ='';
var help='';
var a_1 = "txt1";
var a_2 = "txt2";
...
for (i=1;i<=100;i++)
{
help = 'a_' + i; // This line should be "parsed twice" !
result = result + help;
document.write(result);
}
Of course, I can avoid this by using the if-, or case-function for each "a_ i",
but this would make my js file very big.
So is there a way to parse this "help line" twice with js?
I asume, I could do it with including one js file in another, but I dont like this way?
No PHP , because the code should work clientside
Better to use an array.
eval() is the function for "double parsing" (but could be really dangerous !)
