How jQuery selects elements using CSS?
jQuery uses CSS selectors to select and manipulate elements on a web page. This powerful feature allows you to target HTML elements using the same syntax you would use in CSS stylesheets. The css(name) method returns a style property value from the first matched element.
CSS Selector Syntax
jQuery follows standard CSS selector patterns to identify elements ?
-
$("element")? Selects all elements of a specific type -
$("#id")? Selects element by ID -
$(".class")? Selects elements by class name -
$("element.class")? Selects elements with specific class
The css() Method
Here is the description of the parameter used by the css(name) method ?
- name ? The name of the CSS property to access
Example
You can try to run the following code to learn how jQuery selects elements and retrieves their CSS properties ?
<html>
<head>
<title>jQuery CSS Selector Example</title>
<script src = "https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script>
$(document).ready(function() {
$("div").click(function () {
var color = $(this).css("background-color");
$("#result").html("That div is <span style = 'color:" +
color + ";'>" + color + "</span>.");
});
});
</script>
<style>
div {
width: 60px;
height: 60px;
margin: 5px;
float: left;
cursor: pointer;
}
</style>
</head>
<body>
<p>Click on any square:</p>
<span id = "result"> </span>
<div style = "background-color:blue;"></div>
<div style = "background-color:gray;"></div>
<div style = "background-color:#123456;"></div>
<div style = "background-color:#f11;"></div>
</body>
</html>
In this example ?
-
$("div")selects all div elements using CSS element selector -
$(this)refers to the clicked div element -
css("background-color")retrieves the background color property -
$("#result")selects the element with ID "result"
Conclusion
jQuery's CSS selector integration provides a familiar and powerful way to select DOM elements using standard CSS syntax, making it easy to retrieve and manipulate element properties.
