How to remove z-index attribute in jQuery

When using jQuery to manipulate web page element styles, sometimes we need to delete the z-index style that has been set. The following will introduce how to remove z-index style in jQuery and provide specific code examples.

First, let’s understand what the z-index style does. z-index is a CSS property that controls the stacking order of elements in a stacking context. Elements with higher z-index values override elements with lower z-index values. Sometimes we need to remove the z-index style that has been set, perhaps to restore the default stacking order of elements, or to reset the z-index in a dynamic operation.

Here are the steps on how to remove z-index style in jQuery:

1. Select the element where z-index style needs to be removed. Elements can be selected by their class name, ID, tag name, or other selectors.
2. Use jQuery’s css() method to remove the z-index style. You can remove the z-index style that has been set on an element by setting the value of the z-index attribute to null or the empty string.

The following is a specific code example that demonstrates how to remove the z-index style in jQuery:

       
  
Box 1
 
Box 2
 删除 z-index 样式   

In the above example, we defined two different z-index styles. For box elements with an index value, use the jQuery method to remove their z-index style when the button is clicked. When the button is clicked, the z-index styles of the two box elements will be removed and restored to the default stacking order.

Through the above code example, we can clearly understand how to remove z-index style in jQuery. Hope this article helps you!
