VisualizaçõesWant to get the length condition of innerText for the number of instances not the number of characters
I have: document.querySelectorAll('div.stops') that appears with innerText "Direct" twice on the page.
So I want to apply a condition that if the text "Direct" appears twice, then do something. I have a code like below, but it does not give me the length of the number of times the word "Direct" appears. Instead, it just gives me the number of characters, which is 6.
for(let i=0; i < document.querySelectorAll('div.stops').length; i++){
if (document.querySelectorAll('div.stops')[i].innerText == 'Direct'){
// Do something
}}
Image where the text "Direct" appears 2 times
Screenshot of the console where I tried to find the length

Cache your elements. Use
Array.fromto create an array from the "array-like" list of nodes thatquerySelectorAllreturns. That way you have access to array methods likefilter.filterout the elements that have 'Direct' as their textContent. Note:filterreturns a new array.If the length of that array is 2 do the thing.
const stops = document.querySelectorAll('.stops');
const direct = Array.from(stops).filter(stop => {
return stop.textContent === 'Direct';
});
if (direct.length === 2) {
console.log('Good');
}<div class="stops">Direct</div>
<div class="stops">Karen</div>
<div class="stops">Indirect</div>
<div class="stops">Bus</div>
<div class="stops">Banana</div>
<div class="stops">Direct</div>
