jQuery’s selector parameters allow you to select elements or collections of elements that need to be operated on in the DOM tree. . You can use CSS selector syntax to specify selectors for elements. For example, to select a selector that selects all paragraphs, you would use the following code:

$('p')

This will select all paragraph elements in the document. You can also use compound selectors to select elements based on multiple criteria. For example, to select all elements with classes "red" and "bold" you can use the following code:

$('.red.bold')

2. Event Parameters

$('button').click(function() {
  // do something here
});

var text = $('div').text();
