Discuss the problem of jquery carousel chart not displaying anchor points

When developing websites and applications, using jQuery carousels is a very common technology. However, sometimes one encounters an issue where the carousel does not display anchor points. This article will explore the causes and solutions to this problem.

1. Problem description

When using the jQuery carousel plug-in, we usually hope to add a navigation bar below the carousel to indicate the position of the current carousel. This navigation bar is generally presented in the form of anchor points, and each anchor point corresponds to a carousel image. However, sometimes you encounter a problem: although the anchor exists, it does not appear on the page.

2. Cause of the problem

The reason for this problem is that the anchor point style is set to display:none. This is because many carousel plug-ins use JavaScript to bind the carousel image and the corresponding anchor point together. The plug-in will set the position of the anchor point and the carousel image in the same div container, and set the display property of the anchor point to none to hide it.

3. Solution

1. Modify the CSS style

In order to display the anchor point, we need to modify the CSS style and set the display attribute of the anchor point to block, so that It shows up. You can add the following code in the CSS file:

.carousel-indicators {
  display: block !important;
}

2. Use jQuery to control the style

We can also use jQuery to control the style. Add the following code to the JavaScript file of the carousel:

$(document).ready(function(){
  $('.carousel-indicators').css('display', 'block');
});

This code will be executed after the page loads and sets the display attribute of the anchor to block.

Summary:

In this article, we explored the problem of jQuery carousels not displaying anchor points and provided two solutions. By modifying the CSS style or using jQuery to control the style, we can easily solve this problem to achieve the normal display of the carousel and anchor points.
