Local Storage Jquery

问题:

I'm working on local storage using jQuery. I've got an input field in which you can type some text, press enter, refresh and the text is still there. So that's working fine.

But I want to combine it with a different function I wrote. In this function a user can click on a grey button which will then "activate" it so it turns red, and it will add a 1 to the container. It's a "like button".

So how can I save the click counter information (button turning red, and value updated) using local storage?

I made this jsfiddle: http://jsfiddle.net/Yazuri/7ZxMK/

jQuery(function ($) {

  if (typeof (window.localStorage) != "undefined") {


      $("input[type=text]").val(function () {
          return localStorage.getItem(this.id);
      });

      $("input[type=text]").on("change", function () {
          localStorage.setItem(this.id, $(this).val());
      });
  }
});

Here is your Updated Fiddle

 $("input[type=text]").each(function(){
     $(this).val(localStorage.getItem(this.id));
 });


 $("input[type=text]").on("change", function () {

     localStorage.setItem(this.id, $(this).val());
 });

You cannot write it in this way $("input[type=text]").val(function () {}). There is not event on val.

You can store the counts from the "hearts"

Updated your Fiddle

JSFIDDLE

$(document).ready(function () {

    $('.clickheart').click(function () {
        $(this).find(".output").html(function (i, val) {
            if (val < 1) {

                $(this).addClass('heartrood');
                localStorage.setItem("hearts",  val * 1 + 1);
                return val * 1 + 1;

            } else {
                $(this).removeClass('heartrood');
                localStorage.setItem("hearts",  val * 1 - 1);
                return val * 1 - 1;
            }
        });
    });


});

Demo Fiddle

1. Retrieve and save the total number of clicks
   var result = $(".output").text(); localStorage.setItem('click', result);

2. If the local storage exists with key click show it in the div
   if (localStorage.getItem('click') != null) { $('.output').text(localStorage.getItem('click')); }

Hope it helps...!!
