If I want to save this as a jQuery DOM object and then select it, which method below should I use?
var element = $(this)
And then for selecting
$(element)
Or simply
var element = this
Also, if I want then to concatenate element into a larger selector, is this:
$(element + " .class")
the right way?

Usually when you encounter $() , that means the developer is using a javascript library, such as jQuery. The $ symbol is the namespace for those libraries. All the functions they define begin with $. , such as $. get() .
$ is another, which is just an alias to jQuery . $$ is not provided by jQuery. It's provided by other libraries, such as Mootools or Prototype. js. More importantly, $$ is also provided in the console of modern browsers as an alias to document.
To store the form data in JavaScript localStorage, we'll use the setItem() method. It stores the data in the localStorage object and takes the key and value parameters as input. The parameters can be later used to retrieve the data when the browser reloads the page or a new session is initiated.
After a value is assigned to a variable using the assignment operator, you can assign the value of that variable to another variable using the assignment operator. var myVar; myVar = 5; var myNum; myNum = myVar; The above declares a myVar variable with no value, then assigns it the value 5 .
var element = $(this)
Then you can use element instead of $(this). You don't have to insert element into $() anymore.
For example : element.remove() instead of $(this).remove()
