Do you want it so when you hover over option with `value="1"` that the title object is set to `1` and so on so for down to `option` where `value="4"`? – EGC Nov 06 '19 at 03:20

Answer 1

In this code you are storing current title in var x. you need to write like this:

document.title="Some Text or variable";

if you need to set value of dropdown item as title then to give id to select tag then var newtitle = document.getElementById("id_of_selectTag").value; document.title=newtitle;

Answer 2

There is already answers on StackOverflow: Get selected value in dropdown list using JavaScript and How to get the title of HTML page with JavaScript. You can set title assigning the desired value to document.title variable.
