Cannot Use Query Selector With Id's That Includes "."

Assume that I have a

I want to select this li. To be able to achieve it, I wrote, var id='gen__1002_____46.14_li'; document.querySelector('#

Solution 1:

You need to escape the dot

$('#thisIs\\.anId') // will select <span id="thisIs.anId">test</span>

And in pure js:

var id="gen__1002_____46.14_li";
id = id.replace(/\./g, '\\\\.'); // escaping dots using regex
document.querySelector("#" + id);

EDIT

If you just want to select element by id, use getElementById()

document.getElementById(id);
