In the Google Translator I've made a second instance of Google Translate with
var makediv = document.createElement("secondinstance");
makediv.innerHTML = '<iframe id="iframenaturalID" width="1500" height="300" src="https://translate.google.com"></iframe>';
makediv.setAttribute("id", "iframeID");
var getRef = document.getElementById("gt-c");
var parentDiv = getRef.parentNode;
parentDiv.insertBefore(makediv, getRef);
And I'm trying to copy text from auto-correction of the first instance to the textarea of the second instance:
I'm trying this (this code works if I just copy html within the Chrome inspector{using [0] or [1] to select elements with the same IDs}, however it's only possible to use two instances of the translator with iframe embedding):
setInterval(function() {
var childAnchors1 = window.parent.document.querySelectorAll("#spelling-correction > a");
var TheiFrameInstance = document.getElementById("iframeID");
TheiFrameInstance.contentWindow.document.querySelectorAll("#source").value = childAnchors1.textContent;
}, 100);
But the console says that it cannot read property "document" of undefined at eval, and says that the problem is in this line:
TheiFrameInstance.contentWindow.document.querySelectorAll("#source").value = childAnchors1.textContent;
I've tried embedding another website, and it also didn't work. I also tried to call iframe by "iframenaturalID", and tried to write TheiFrameInstance.contentWindow.document.querySelectorAll
without the contentWindow
, but nothing seems to work.
I would very much appreciate any help.
Ok, I made it work with a different method of creating iframe:
var a = document.createElement('iframe');
a.src = "https://translate.google.com";
a.id = "iframenaturalID";
a.width = "1000";
a.height = "500";
document.querySelector('body').appendChild(a)
And (copying textcontent from the correction div to the iframe textarea):
let iframe = document.getElementById("iframenaturalID");
setInterval(function() {
let source = iframe.contentWindow.document.getElementById("source");
let destination = window.parent.document.querySelector("#spelling-correction > a");
source.value = destination.textContent;
}, 100);
Now it does what I tried to do, however I still get mistake message: Uncaught TypeError: Cannot set property 'value' of null
at eval
, which points at this line: source.value = destination.textContent;
. It's not a big problem though, but still it's strange that it returns this mistake...
