I call my js function from HTML code from another file. Now I would like to create a input button on page using createElement() in my called function. I used something like this but doesn't seems to work. Lets show is the function being called function show(){ var element=createElement('button'); element.setAttribute('id', 'show'); element.appendChild(document.createTextNode('Button')); } what is the right way
