How to set tab title when opening a new tab?

Question

I am opening a new tab like this

$('#HelpMenu li a').on('click', function (e) {
    let linkToAppendTo = "http://help.mysite.com/" + e.target.innerText;
    let openTab = window.open(linkToAppendTo, "_blank");
    openTab.focus();
});

and don't know how to change the opening tabs title.

As for the provided link that is only changing a current tab title, not a new one that has been opened as I am showing

Answer 1

尝试在新标签的onload事件上设置标题。

openTab.onload = function() { this.document.title = "Title"; }

Answer 2

Try this

let openTab = window.open(linkToAppendTo, "_blank");
openTab.document.title = "Some title";
