Why does != work and just = doesn't?

Question

Here\'s my code:

  if (document.getElementById(\"hiddenButton\").style.visibility != \"visible\") {
     document.getElementById(\"hiddenButton\").style.visibili         


        

Answer 1

The = is an assignment operation.

The != is an inequality operator.

The == is an equality operator.

I guess what you need is the == operator. So replace your code with:

if (document.getElementById("hiddenButton").style.visibility == "hidden") {
