jQuery attr() Method The attr() method sets or returns attributes and values of the selected elements. When this method is used to return the attribute value, it returns the value of the FIRST matched element.
Answer: Use the jQuery attr() Method You can simply use the jQuery attr() method to get or set the ID attribute value of an element. The following example will display the ID of the DIV element in an alert box on button click.
$(this) is a jQuery object that is wrapping the DOM element this and jQuery objects don't have id properties. You probably want just this.id to get the id attribute of the clicked element.
No, they're not exactly the same.
They'll both return the element's ID, but if the element has no ID, then this.id will return a blank string while $(this).attr("id") will return undefined.
