Jquery Script won't click a button

Question

I use this script to trigger button click upon keyup event inside the textbox, but it fails to do what is required:

 $("#id_of_textbox").keyup(function(event){
 if(event.keyCode == 13){
     $("#id_of_button").click();
 }
});

Answer 1

try: https://jsfiddle.net/Cuchu/60u94fty/

<input type="text" id="id_of_textbox" />
<button id="id_of_button">Click Button</button>
<script type="text/javascript">
document.getElementById("id_of_button").onclick = function() {clickFunction()};

function clickFunction() {alert("hello");}

$("#id_of_textbox").keyup(function(event){
   if(event.keyCode === 13){
      $("#id_of_button").click();
   }
});

</script>
