From Around the Web: 20 Fabulous Infographics About javascript add id to element


I use javascript to add an id to any element on my page. This gives me three benefits. First, I can identify the element easily, without the need to remember the DOM. Second, I can manipulate the element without the user seeing my code, and third, I can prevent future modifications.

I can also change the element’s class name so that it’s a “proper” element. The only other way to do this is to delete the element.

There are two ways to do this, either by adding the class name manually, or by adding an id. This article covers both methods. For example, if I want to change the element’s class name, I can add the class name manually, like this: . This method also allows me to remove the element’s class name, like this: .

The second method, adding an id, creates an element with a unique id. It also means I can add and remove it any time I want. I can also add multiple elements with the same id without breaking the page, like this.

Adding an id to a class allows me to add it to every element with the same class. I can simply use the id to access all the functions attached to that element.

Using an element’s id also makes it possible to update the element’s appearance without re-initializing it. This is useful for things like jQuery plugins.

I find the use of id’s to be a little confusing, especially when there are so many ways to add and remove elements on a page and it always seems to be a matter of which id I’m using. For example, here’s how I can add an element with id “top-text” to a page using the jQuery add method. I can also remove it using the jQuery remove method.

With the addition of ids, we now have a handful of ways to link elements on a page. For example, we can use id’s to link elements to each other, to change the contents of an element, or to link to an image or a file. It might seem that we have to use the id to link elements within the same element as well, but there are actually two kinds of ids that we can use. One is the hash id or the object id.

The hash id or object id is a shorthand way of making sure that any element with the same id is only linked to a single element.

The hash id is just a name for the element. For example, if we have a page named “foo”, we can use the hash id as the name of the element that we want to link to. In this case, we could create a div and then attach it to the same id that we used previously.
