Menu
I am making a form where users can input their data. I'd like for this date to be saved by use of local storage. But when i refresh the page only height and weight are still remembered. And i have been quite stuck on trying to make gender , sportivity and birthdate be remembered as well.
HTML5 Local Storage – A Practical Example. The ideal method to store massive data on the client side that persists beyond page refreshes, sessions, and browser restarts is via the localStorage object, provided by the HTML5 web storage API. The localStorage object is accessed and handled via javascript using pre-defined properties and can also be modified using browser debugging tools. 10 thoughts on “ Javascript: How to parse xml, write to html5 local storage, then read from local storage, and allow user to search content. ” Jean-Marc Flamand at 6:26 am. Thank for the article. Question if the pages are on a web server and the book.xml is on my PC.

You are complicating your script. Try this. Working JSFIDDLE
If you are using jQuery once, do not mix it with pure javascript, like
document.getElementById()
. And do not create a height
variable to store the $('#height').val()
, you can use this directly. Code is more readable.Update: If you are using jQuery 3, unload will throw an error. You should use this instead:

We all have those days when we have a lot of things to accomplish, but no way to know if we will complete all of them. In these situations, a to-do list is extremely helpful. There are great mobile apps, online tools, and even WordPress plugins which perform this task, but have you ever wondered how long it would take to create one by yourself?
In this tutorial, we will create a basic to-do list. Tasks will fall into one of three categories – pending, in progress, and completed. Our application will allow new tasks to be created, which go into the pending category by default. Tasks can easily be moved between categories using drag and drop technology. Of course, tasks can also be deleted.
Prerequisites
The following libraries are used in this project.
- jQuery 1.10.2
- jQuery UI 1.10.3
- Bootstrap 2.2.2
Creating the Markup and CSS
Let’s create the basic look and feel of the application before adding the functionality via JavaScript.
Next, add some styling to the elements using the following CSS.
Our static to-do page should look like the following image.
Defining the JavaScript Constants
Throughout this tutorial, we will be referring to certain constants to avoid hard coding values. These constants are shown below.
Creating Tasks
Tasks are created using the following JavaScript function.
The following code sample shows how a single task is generated.
Deleting Tasks
Removing tasks is fairly simple, and can be accomplished using the following function.
Saving Tasks in Local Storage
The tasks we create could be stored using a database, cookies, or a number of other technologies. However, in this application we’re going to use HTML5’s local storage for its simplicity. In JavaScript, the variable
localStorage
stores all of this data. The following code sample shows how the to-do list data is retrieved from local storage.Each task would be stored within the
data
variable. An example task object is shown below.![Html/javascript Write To Local Storage Html/javascript Write To Local Storage](https://www.taniarascia.com/static/5c1ef4b897ef10bbfcd582d85f3c75fc/e703e/Screen-Shot-2017-12-18-at-5.46.10-PM.png)
We update the saved data in local storage using the following code.
Submitting the To-Do Form
When the to-do form is submitted, a new task is created and added to local storage, and the contents of the page are updated. The following function implements this functionality.
Implementing Drag and Drop
jQuery UI provides drag and drop functionality. We need to make each task draggable and each of the three categories droppable. To delete a task, we need to hide the delete area by default, and show it during the time an item is being dragged. Therefore, we first modify the
generateElement()
function slightly to first make the to-do list items draggable, and then make the delete area visible when the item is being drug.Secondly, we need to add the
droppable()
function to each of the categories as the elements are supposed to be dropped in any one of the three areas.Thirdly, we need to add some code to delete tasks when they are dropped in the delete area.
Conclusion
The final code is available on GitHub. You can also check out the project’s live demo.
