How do I get the value of checkbox?



<input type="checkbox" aria-checked="false" class="cloud-private" value="" data-spm-anchor-id="">

My java script :
( i want to click this checkbox if it is not checked ,but this does not work )

var z = document.getElementsByClassName('cloud-private'); 
if (z[0].aria-checked=='false'){ 


Should not be using aria-checked here in this way. Should be using the checked attribute as is shown in the checkbox spec on MDN.

let cloudPrivateCbxs = document.querySelectorAll('.cloud-private');

if (cloudPrivateCbxs && !cloudPrivateCbxs[0].checked) { 

Here I used a useful variable names (never use single letter variable names except for simple counters like those in for loops), used querySelectorAll instead of getElementsByClassName, then I first check if the variable contains anything, then I simply check the checked attribute to see if it returns false. It is returning a boolean so I can use the logical NOT operator ! rather than check directly if it is equal to false.
