javascript - Why does this event listener not work? -
i tried adding event listener cars3 id'd paragraph when click paragraph should execute getvalue() method not work. don't understand why. thanks.
<!doctype html> <html lang="en"> <head> <script> function getvalue() { var x=document.getelementbyid("cars").value; document.getelementbyid("cars2").innerhtml = x.tostring(); } document.getelementbyid("cars3").addeventlistener("click", getvalue()); </script> </head> <body> <h1 id="myheader" onclick="getvalue()">"click here !" </h1> <p id="cars3">afaf</p> <select id="cars" name ="cars"> <option value="volvo">volvo</option> <option value="saab">saab</option> <option value="mercedes">mercedes</option> <option value="audi">audi</option></select> </select> <p id="cars2">afaf2</p> </body> </html>
remove brackets:
addeventlistener("click", getvalue()); //--------------------------------^^ making it:
addeventlistener("click", getvalue); edited
also move script tag below body. code not waiting page rendered, hence document.getelementbyid("cars3") fails fetch element.
<body> ... </body> <script> function getvalue() ... <script>
