Rather than setting up the function within the onclick attribute in the HTML, you can instead just set it within the function - HTML: <div class="but" onclick="dog()"> <button>dog</button> </div><br /> JS: function dog(){ document.getElementById('para').innerHTML = 'dog'; document.getElementsByClassName('but')[0].style.visibility='hidden'; } Additionally, you seem to have forgotten to specify which element of class "but" you wanted to set the visibility of, so adding in the [0] just fixes that error

Can anyone tell me why this works only for the first click. I mean when you click any button again it shows error that ".... is not a function "
