How to change text color in jquery

In web development, jQuery is a very commonly used JavaScript library, which makes JavaScript programming more convenient and easy to understand. If you need to change the color of text, it's very simple to do so using jQuery.

First, introduce the jQuery library into your web page. You can add the following code to your HTML file:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

This will download the jQuery library from Google's CDN. You can also download the local jQuery library, but the above code will be faster using a CDN.

Next, select an ID or class on the element you want to change the color of. For example, if you have a paragraph that needs to be changed in color, use the class selector to select it:

<p class='change-color'>这是需要更改颜色的文本。</p>

Then, we are going to use jQuery to select this paragraph and change the color. The following code will first select all elements of this class and then use jQuery's css() method to change the text color to red:

<script>
$(document).ready(function(){
  $('.change-color').css('color', 'red');
});
</script>

In the above code, we use the document.ready() method to ensure that the code is in the DOM Execute after loading. Then, use the jQuery selector $('.change-color') to select all elements with class name 'change-color', and finally use the .css() method to change the text color to red.

In addition to using the color name directly (e.g. 'red'), you can also use RGB values, hexadecimal values, or abbreviations of the color name. For example, you can change the text color to green using the following code (using hexadecimal values):

$('.change-color').css('color', '#00FF00');

In addition to the css() method, jQuery also provides many other methods to change the properties of an element. and style. No matter what properties or styles you need to change, jQuery can help you make it happen. For example, if you need to change the font style and size of text, you can use the following code:

$('.change-color').css({
  'font-style': 'italic',
  'font-size': '24px'
});

The above code uses an object that contains multiple properties and values ​​to set multiple styles. You only need to add the properties that need to be changed and the corresponding values.

In short, jQuery provides a very simple and convenient method for color changes in web development. You can change the text color or other styles of any element just by using selectors and the css() method. Keep trying and learning, and you can learn more jQuery tricks.
