Populate form with localStorage

forms, javascript, jquery-mobile, local-storage

Solution

All you need to do is add a `ready` method to load the data.

$(document).ready(function() {
  $(input[name=server]).val(localStorage.getItem("server"));
});

Or non-JQuery answer.

function save_data() {
  // Save functionality here...
}

function load_data() {
  var input = document.getElementById("saveServer");
  input.value = localStorage.getItem("server");
}

load_data();

Just make sure your `form` exists before any of the JavaScript to populate it is executed.

Here is a working example.

Problem

I'm building a webapp where I have a settings panel. I have a code that saves data from form to localStorage, but how could I make it populate the form automatically on pageload if there is some data saved to localStorage? This is my code for the form: ``` <label for="serveri"> Server: </label> <input type='text' name="server" id="saveServer"/> <button onclick="save_data()" type="button" value="Save" id="Save" data-theme="a">Save</button> <script> function save_data() { var input = document.getElementById("saveServer"); localStorage.setItem("server", input.value); var storedValue = localStorage.getItem("server"); } </script> ```
