How to set attribute to using selenium javascript?

Question

I am trying to set attribute to a slider. I am using javascript to automate, I have currently tried the below code,

it('should pan plots when you click and drag', function(done) {
                driver.sleep(2000);

                driver.findElement(webdriver.By.css('._md-slider-wrapper')).click().then(function(){
                driver.findElement(webdriver.By.css('._md-thumb-container')).SetAttribute("style", "left: 22px");
                    done();
                });

but it is not working. I have also tried to pass the element to a function and then try to set the attribute but it didnt work either. i am basically trying to set the value to a slider.

@user2987322, just extract Javacsript line from provided JavaScriptExecutor code. There is no other possibility to change element's attribute using selenium, except with JavascriptExecutor, but as long as you use pure JavaScript you don't need "executors" — Andersson

Try this:

driver.executeScript("document.querySelector('._md-thumb-container').setAttribute('style', 'left: 22px'");

If you open the page google.com, and type the commands below in the inspector, what will you see? document.querySelector("#q"); document.querySelector("#q").setAttribute('aria-hidden', 'false'); document.querySelector("#q"); I used the 2nd command to change the attribute aria-hidden. For your case, maybe you should try the same to test whether it works or not.
