html - Addding a item to a list in JavaScript -


i'm debutant in javascript please patient me, in code have list of ingredients, when user puts in input area , click on body, text must added item in list before last one, code not working , can't find problem.

<!doctype html>  <html>    <head>      <title>kitchen</title>      <script type="text/javascript">         function ajout(){              var newingredient = document.createelement("li");              var ingredient = document.getelementbyid("in2").value;              var text=document.createtextnode(ingredient);             newingredient.appendchild(text);             var lastone=document.getelementbyid("last");             var list=getelementbyid("listecommissions");             list.insertbefore(newingredient, lastone);          }                </script>   </head>   <body onclick="ajout()">      <br /><br /><br />     <ul id="listecommissions">          <li> 1kg de farine </li>          <li> un pack de lait </li>           <li id="last"> add 1 more ... </li>     </ul>      <form>         <input type=text id="in2" placeholder="add ingredient"/>     </form> </body>  </html>

so, main problem line

var list = getelementbyid("listecommissions");

which should be

var list = document.getelementbyid("listecommissions");

this discovered when use debugger tools (web console). second thing onclick should onclick. see jsfiddle here.

i recommend separate javascript html i. e. use no inline tags js. can adding domcontentloaded eventlistener window , within add eventlistener body (in case) or better button:

window.addeventlistener('domcontentloaded',function(){   document.getelementbyid('yourbuttonidhere')     .addeventlistener('click',function(){       var newingredient = document.createelement("li");       var ingredient = document.getelementbyid("in2").value;       var text = document.createtextnode(ingredient);       newingredient.appendchild(text);       var lastone = document.getelementbyid("last");       var list = document.getelementbyid("listecommissions");       list.insertbefore(newingredient, lastone);     }); });
