title: iBooks Author/iAd Producer Widget User Text Disappears
body: <p>I'm using iAd producer to create HTML widgets for iBooks I'm making using iBooks Author.  I've done some research and learned that I can have user input saved into local storage by way of a variable that is called every time the widget is opened.  This is great except for the new problem of having to create hundreds of text box widgets all with different variables so I can use these text boxes on multiple pages.  Is there a way for me to automate this using Java Script? One idea I had was to use a "while" function to tell the script to ++ the variable if the one it tried to use was not empty.  Example: the variable "001" was already used so the code would ideally set the next user text to variable "002". Preferably, I'd like to be able to create one widget with this code that I could reuse anywhere else.<br>
  Here is the code I'm currently using:</p>
  
  <pre><code>/*Widget code*/
  
  this.onViewControllerViewWillAppear = function (event) {
      var theValue = this.outlets.textField;
      if (localStorage.getItem("theKey102") === null) {
          theValue.value = "";
      } else {
          theValue.value = localStorage.getItem("theKey102");
      }
  };
  
  /*This is the code for one of the text boxes I'm using */
  
  this.onControlValueChange = function (event) {
      var theValue = this.viewController.outlets.textField;
      localStorage.setItem("theKey102", theValue.value);
  };
  </code></pre>
