javascript - how do I store these three variables into local storage? -

-

i creating mad lib , can't variables store inside local storage. have 3 variables: noun, nountwo, , name. end goal once variables stored user able reload page , last story generated displayed @ top of page. 

  
  
    <script>        function lib() {      var storydiv = document.getelementbyid("story");      var nountwo = document.getelementbyid("nountwo").value;      var noun = document.getelementbyid("noun").value;      var name = document.getelementbyid("name").value;      storydiv.innerhtml = "one day " + noun + " attacked " + nountwo + ", , defeated " + name + "!";      noun.replace('noun', noun.value);      noun.replace('nountwo', nountwo.value);      noun.replace('name', name.value);      }        var libbtn = document.getelementbyid('generate');      libbtn.addeventlistener('click', lib);        localstorage.setitem('noun', noun.value);        console.log(localstorage);        </script>
  
    <html>      <head>          <title>mad lib lab</title>      </head>      <body>      <h1>mad libs</h1>        <div id="result"></div>        <div id="story">              1 day              <input type="text" id="noun" placeholder="noun">              attacked              <input type="text" id="nountwo" placeholder="noun">              ,but defeated              <input type="text" id="name" placeholder="famous person">!        <button id="generate">generate</button>      </div>        </body>      </html>
  
 
 
  
if need display last story, don't need store 3 variables.
  
also here, noun doesn't contain either of string you're searching (it contains wrote in noun input):
  
noun.replace('noun', noun.value); noun.replace('nountwo', nountwo.value); noun.replace('name', name.value); 
  
this should trick:
  
function lib() {     var storydiv = document.getelementbyid("story");     var nountwo = document.getelementbyid("nountwo").value;     var noun = document.getelementbyid("noun").value;     var name = document.getelementbyid("name").value;     var story = "one day " + noun + " attacked " + nountwo + ", , defeated " + name + "!";     storydiv.innerhtml = story;     localstorage.setitem('laststory', story); }  var libbtn = document.getelementbyid('generate'); libbtn.addeventlistener('click', lib);  if(localstorage.getitem('laststory')) {     document.getelementbyid('result').innerhtml = localstorage.getitem('laststory'); }
