html5 localstorage没有保存输入

Question

I'm trying to safe a value in localstorage to use it later on other pages, but I can't quite get it to work.

My input field:

<input type="text" name="test" value="" id="test" required />
         <span class="highlight"></span>
         <span class="bar"></span>
         <label>enter something</label>

My script:

<script>

function getStorage(type) {
  var storage = window[type + 'Storage'],
    delta = 0,
    p = document.createElement('p');

  if (!window[type + 'Storage']) return;

  if (storage.getItem('value')) {    
    p.innerHTML = type + 'Storage: ' + storage.getItem('value');
  } else {
    p.innerHTML = type + 'nothing safed';
  }

  document.querySelector('#output').appendChild(p);
}

getStorage('test');


addEvent(document.querySelector('#test'), 'keyup', function () {
  localStorage.setItem('value', this.value);
});


</script>

My output:

    <p id="output"></p>

Note: I'm using h5utils.js ( https://java.net/projects/prototype/sources/svn/content/trunk/demosprojects/AjaxAdmin/web/h5utils.js?rev=11 ) to make it all work, but I can't get output. No errors in the console.

Answer 1

You're calling the getStorage function passing a type of 'test', which then attempts to look up window.testStorage which doesn't exist of course.

Use...

getStorage('local');

... instead to look up localStorage.
