I may also expand this into another tutorial and show you how to create a nice menu using the technique. I know the tutorial was pretty basic, but I hope that the example above gives you an idea of how this can be used. More importantly, the callback is fired in the context of the current DOM element. Each time the callback runs, it is passed the current loop iteration, beginning from 0. When called it iterates over the DOM elements that are part of the jQuery object. With the map function, we map every element of the array to the custom components in a single line of code. each () method is designed to make DOM looping constructs concise and less error-prone. The map is a JavaScript function that can be called on any array. The value stored in the map must be mapped to the key. When the div is clicked it could expand with SEO rich content and links. A map is a data collection type where data is stored in the form of key-value pairs. Now if we wanted to add some quality SEO content to help the site rank we could put it in a hidden div so that it doesn’t distract the customer. Here is an example of something you could use this for. When you click the toggle link the hidden box will appear. You should not see the Div when the page loads. We will create a link that goes no where and add the onclick property below. Now all we have to do is create a link that will call the toggle function and pass the ID of the Div we want to toggle. Then if “display: block ” for the #hidden div we will change it to be “display: none ” else we will change the display to none.Īdd the code to your page in the head just below the style. Next we are using the Document Object Model to get the current state of the display attribute. The script above is creating the function “toggle” an passing the value “id”. Var state = document.getElementById(id).style.display ĭocument.getElementById(id).style.display = 'none' ĭocument.getElementById(id).style.display = 'block' Below is the Javascript code that we will add the the Head section of the page. Basically this means that we can use this one function to show or hide more than one Div on the same page. We will pass the ID attribute of the Div to the function. In order to show the div we will need to add a Javascript function. Now when you preview the page you will not see the Div. To do this we will change the display to none in the CSS for the #hidden div. ![]() Ok now I will add some basic style to these boxes. One will be shown and one will be hidden. As long as the user can still see the content when clicking a button you are not displaying different information to the user than you are to the search engine.įirst we are going to start with a very basic page layout and create a 2 Divs. In theory hiding information in a Div is not against Google’s rules. Another reason would be for SEO purposes. ![]() You may want to create a drop down type menu or a box that will show more information when you click a link. ![]() There are a few reasons you may want to hide a Div in a website design. This is with jQuery: $(".myBox").This tutorial will show you how to create a hidden Div and display it with the click of a link. If you absolutely need to use JavaScript, one way is to find a link inside the div and go to its href when the div is clicked. But, if there is a ton of content in there, it’s absolutely horrible for accessibility, reading all that content as the interactive link. It doesn’t break text selection and respects other “nested” interactive elements.Īnd remember you can make links display: block, so the whole rectangular area becomes “clickable”. The (or whatever wrapper element) remains semantic and accessible, while being “clickable” over the whole area. Update November 2020: I think the best possible technique for this is Method 4 in this article.
