I have a variable with a string, let's say this one, which I then display on a page on the site:
let value = "qwe asd — bensound summer";
document.getElementById("text").innerHTML = value;
And I want to remove its second part when displaying this line on the page bensound summer along with a dash —.
And in order to receive only the first part, which is before the dash, when displayed on the page, in the form: qwe asd.
I read about str.split() but didn't find anything like it and didn't quite understand how it all works.
Use the split method
let value = "qwe asd - bensound summer";
value = value.split('-')[0] //
document.getElementById("text").innerHTML = value;
You can use it like this:
let value = "qwe asd — bensound summer";
let splittedString = value.split("-");
document.getElementById("text").innerHTML = splittedString[0];
Hope, it helps!!
