I believe you are looking for the textContent property of the div elements. So if you select a specific div (e.g. document.getElementById('print')), you can alter its textContent property like so document.getElementById('print').textContent = 5;

el.innerHTML.match(/-?d*.?d+/)[0]

Will pull the first numeric value found in the element. You will need to pull the element into el.

I have started using javascript from today to create one plugin for firefox. I want to get the numeric value from a webpage which i will further use in a conditional statement. These value collectively create a timer on the webpage.

<div class="ureact-countdown_container-dark__3yLv6 ureact-countdown__container__AavqD queue-control-row_countdown__12Ijv">
        <div class="ureact-countdown_digit__3tqK_">
            02
            <span class="ureact-countdown_label__Mebe5">hr</span>
        </div>
        <div class="ureact-countdown_digit__3tqK_">
            35
            <span class="ureact-countdown_label__Mebe5">min</span>
        </div>
        <div class="ureact-countdown_digit__3tqK_">
            43
            <span class="ureact-countdown_label__Mebe5">sec</span>
        </div>
</div>

I want the numeric values stored in 3 variables.

I have saw some tutorials where they are using the following code to store the values mentioned within a class. But I have no prior knowledge on javascript.

var value = document.getElementsByClassName();

But as you can see all have the same class name, so how would i do that.

Any help or references will be appreciated from where I can learn.
