I try to open links, what i found, in a new window, then search for a text, and then close the new window. But its not working, the new window not closed, and the search also not working. and just open the first window.
links = document.getElementsByTagName("a");
for (var i = 0, l = links.length; i < l; i++) {
var link = links[i];
if (link.href.indexOf("jooble") !== -1) {
var newWindow = window.open(links[i].href);
setTimeout(function(){
console.log("5s")
if (
(newWindow.document.documentElement.textContent || newWindow.document.documentElement.innerText).indexOf('Jófogás') > -1) {
console.log("Jófogás")
} if(newWindow){
newWindow.close();
}
}, 5000);
}
}`
unfortunately you cant's access to a window.open html contents.
var mywindow = window.open('https://www.wikipedia.org/', 'title', 'height=500, width=500');
console.log(mywindow.document) //you will get an empty html tag
You have to use a Web Scraper library like puppeteer for that
You not creating variable that your problem, place let before links and try again
let links = document.getElementsByTagName("a");
for (var i = 0, l = links.length; i < l; i++) {
var link = links[i];
if (link.href.indexOf("jooble") !== -1) {
var newWindow = window.open(links[i].href);
setTimeout(function(){
console.log("5s")
if (
(newWindow.document.documentElement.textContent || newWindow.document.documentElement.innerText).indexOf('Jófogás') > -1) {
console.log("Jófogás")
} if(newWindow){
newWindow.close();
}
}, 5000);
}
}
