How to set color in jquery

With the continuous development of web design, more and more Internet practitioners are beginning to pay attention to the user experience of web pages. The color matching of web pages is a very critical task. The best color matching is undoubtedly to make the web page more attractive and readable.

jQuery is a very useful tool that can easily help developers perform various operations on web pages, such as operating DOM and CSS. So, how does jQuery set colors?

First, we need to understand some basic jQuery syntax.

1. $(): This is a global object, representing a jQuery object, which can be used to conveniently operate the HTML and CSS of the web page.
2. .css(): Indicates that the CSS properties of the element are to be modified.
3. .attr(): Indicates that the HTML attributes of the element are to be modified.

Next, we will combine two examples to understand how to use jQuery to set colors.

Example 1:

Suppose we want to change the text color of a button. We can achieve this through the following code:

$(document).ready(function() {
  $("button").click(function() {
    $("p").css("color", "red");
  });
});

This code uses jQuery's _click() method. When the button is clicked, the "color" attribute value of the element whose color needs to be changed is set to red.

Example 2:

Suppose we want to modify the background color of a text box. We can achieve this through the following code:

$(document).ready(function() {
  $("input").focus(function() {
    $(this).css("background-color", "#F5F5F5");
  });
  $("input").blur(function() {
    $(this).css("background-color", "#FFF");
  });
});

This code uses jQuery’s _focus() and _blur() methods. When the input box receives focus, its background color changes to gray. When the input box loses focus, its background color changes to white.

These methods can be used for any CSS property, and one or more properties can be modified together. At the same time, through these methods, you can dynamically modify the CSS on DOM elements. For example, we can dynamically set the background color, font color, font size, etc. of the element.

Summary:

In this article, we learned how to use jQuery to set colors through two examples. After understanding some basic syntax of jQuery, we can use it to modify DOM and CSS very conveniently. Using jQuery can effectively improve our work efficiency and development results, and provide more flexibility for website design and user experience.
