How to get a value from a Html radio button

Question

I have a html radio button, but I want to know how can I get a value from it. (I'm working on Electron)

Here is my Radio code

 <label class="container">Ne plus afficher cette page au lancement.<input type="checkbox" unchecked="uncheck"><span class="checkmark"></span>

Basically I want to call a funtion if the box is checked.

for exemple

Function typeFunction(){

//load a window (Not sure if this is right
  mainWindow.loadFile('index.html')

}

Answer 1

First, you need to remove that unchecked tag its useless. Secondly, give a class to the checkbox for example " checkButton ". Lastly, you need to select the Item from the DOM.

const checkBtn = document.querySelector('.checkButton');

If you want to DO something when the checkbox is checked you just need to use the .checked property ->

 if(checkBtn.checked) {
 // do something 
} else {
 // do something else 
 }

Also use function because if you are gonna use it with capital ,,F'' JS is gonna think this is a function constructor .

Answer 2

Give ids to each choice.

id="choice1"

Then get the value by referring to the said id. choice1.value
