Note: As of React 16, componentWillReceiveProps is deprecated, meaning if you are using that version or higher in your project, this is not good advice for you. In the React world, forcing a re-render is frowned upon. You should let the DOM take care of itself when React perceives changes to state or props.

In order to follow these patterns, we sometimes have to do stuff that seems a little silly. Consider this scenario:. The parent makes an API call to fetch the user. From that, we get things like nameagefavorite color. We also get an id from our database. Awesome — lots of data coming into our app. What gives? Side note : Of course we should just get the shoes from the call for the user — this is just a simplified explanation.

The short of it is that React will only update parts of the DOM that have changed. The color preference for the user will update when we get back new information from the API — assuming we are doing something with the response after we update a user.

RefreshControl

If we want the shoe component to grab the new list of shoes, we need to update the props we send to it. Otherwise it will see no need to refresh.

In fact, the way this is written, the ShoeList would never refresh, as we are not dependent on props for rendering. This is a simple switch we can flip. Otherwise, there will be nothing to update. If you pass only refreshShoeList and then toggle based on that boolean, the component will just update forever and ever and ever.

In componentWillReceiveProps we have our only opportunity to view new props as they are coming in and compare them with previous props. Here we can detect changes like in refresh and we can also make checks for new props note, for instance, that refresh is initially undefined.

Whenever I click on the button I can see that the the "handle request" question appears in the console log, but suddenly disappears. My understanding is that something is causing the page to refresh.

So when I console logged the data I was fetching, it rendered for every single list item.

The only solution was to add a button to handle the click event and now it works fine. Either that or make the entire list item a button hehe.

Stack Overflow works best with JavaScript enabled.This quick tip describes how to have your browser remember the state of checkboxes once a page has been refreshed or a user navigates away from your site to come back at a later date. It might be useful to Persist Checkbox Checked State if, for example, you use checkboxes to allow your users to set site-specific preferences, such as opening external links in a new window or hiding certain page elements.

You can include it via a CDN thus:. This allows me to target only those checkboxes I am interested in and not all of the checkboxes on the page. This means that it treats each request as an independent transaction that is unrelated to any previous request.

It has pretty good browser support:. Can I Use namevalue-storage? Data on support for the namevalue-storage feature across the major browsers from caniuse. We can save these in an object literal which we can add to local storage.

Button Click Event Fires WhenEver Page Refresh in tribrachpenpal.fun

Notice the logical OR operator which returns the value of its second operand, if the first is falsy. This is effectively the same as writing:.

This is overkill in such a small example, but is a good habit to get into as your code grows. The last thing to do is to iterate over the checkboxValues variable when the page loads and set the value of the boxes accordingly:. When clicked, this button should check all of the checkboxes. When all of the checkboxes are checked its text should change to Uncheck All and its state should be stored in local storage, too. The only thing that might be slightly unusual here is the use of a ternary conditional in the updateButtonStatus method.

This is a shortcut for an if statement and is the equivalent to:. I have also moved the logic for updating local storage into its own function:.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

You might put that on the form onsubmit handler, but it's not going to help on the button element and even putting it on the form onsubmit handler is not ideal. Then it won't try to submit the form. A few suggestions: 1. Use an HTML5 doctype. It's backwards compatible with HTML 4. Preferably, put them in external.

It's better for performance, reusability, and maintenance. In your functions, put all your variable declarations at the very beginning of the function.

You don't have to search all over to determine if a variable is global or if it has function scope. It's a bit inconsistent, and fragile if any of the page changes. You might consider making it a little more abstract. There's a lot of similar looking code that could probably be rewritten as a reusable function 5. Don't use inline style attributes. Don't use presentational attributes border, align, width, etc.

Don't use tables for layout. I could probably go on, but it's not what you asked.
