How to delete styles in jquery

jQuery is an open source library for the JavaScript programming language, used by many websites to develop dynamic user interfaces and interactive experiences. During web development, sometimes it is necessary to delete the styles of certain HTML elements. This article will introduce how to use jQuery to remove styles from HTML elements.

1. Use the removeClass() method to delete styles

The removeClass() method in jQuery can be used to delete one or more classes of a specified HTML element. Here is an example:

$(“#myDiv”).removeClass(“myClass”);

The above code will delete the "myClass" class of the HTML element with the ID "myDiv".

If you want to remove multiple classes, simply pass the class names as a space-separated list to the removeClass() method. For example:

$(“#myDiv”).removeClass(“myClass1 myClass2 myClass3”);

The above code will delete the "myClass1", "myClass2" and "myClass3" classes of the HTML element with the ID "myDiv".

2. Use the removeAttr() method to delete the inline style

If you want to delete the inline style of the HTML element (that is, the style directly specified through the style attribute), you can use the removeAttr() method. . Here's an example:

$(“#myDiv”).removeAttr(“style”);

The above code will remove all inline styles from the HTML element with the ID "myDiv".

3. Use the css() method to delete the style

You can also use the css() method to delete the style of the HTML element. You can actually style an element using this method, but if you set the attribute value to "none" the style will be removed. For example:

$(“#myDiv”).css(“display”, “none”);

The above code will remove the "display" style of the HTML element with the ID "myDiv".
