I have an input field which is deleting all the words its contains when I'm pressing backspace key.
I tried to implement a small code to delete the words letter by letter but I'm getting an error: selectInput.substring is not a function.
let selectInput = document.querySelector('#searchedWord');
selectInput.addEventListener("keydown", function(e) {
const key = e.key;
if (key === "Backspace") {
selectInput.value = selectInput.substring(0, selectInput.length -1);
// other code to be exectuded below
}
});
What am I missing?
"selectInput" is NOT a string in your context its a DOM-object (or DOM-tree [=array] if multiple elements have been found but since you used an ID "#"searchedWord we should be fine here)
you must access ".value" attribute
Try:
selectInput.value = selectInput.value.substring(0, selectInput.length -1)
You basically already did it right where you assigned it into. :D
