HomeWeb Front-enduni-appHow to modify the indicator point color in uniapp

With the development and popularization of mobile Internet, more and more enterprises and developers are beginning to try to use uniapp for cross-platform development to meet the diverse and rapid update needs of mobile terminals. In uniapp development, indicator points are one of the common UI components. They are often used in scenes such as carousels to indicate the user's current location.

However, when developing with uniapp, we may need to modify the color of the indicator point to achieve better visual effects. This article will introduce in detail how uniapp can modify the color of the indicator point.

1. The use of indicator points in uniapp

Indicator points are one of the more commonly used components in uniapp. They are small dots used to identify the user's current location. Usually, in scenes such as carousels and navigation bars, indicator points play an important role.

In uniapp, we can implement the carousel chart through the swiper component and add indicator points. As shown in the following code:

<swiper>
  <swiper-item>
    <image></image>
  </swiper-item>
  <swiper-item>
    <image></image>
  </swiper-item>
  <swiper-item>
    <image></image>
  </swiper-item>
</swiper>

In the above code, we use the swiper component and set whether to display indicator dots through the indicator-dots attribute. At the same time, we also set the color of the indicator point through the indicator-color attribute and indicator-active-color attribute. Among them, the indicator-color attribute represents the color of the unselected indicator point, and the indicator-active-color attribute represents the color of the selected indicator point. It should be noted that the indicator-color attribute requires the use of the rgba() function to set the transparency of the color.

2. Modify the color of the indicator point

In uniapp, we can modify the color of the indicator point by modifying the values ​​of the indicator-color attribute and indicator-active-color attribute.

For example, if we want to change the color of the unselected indicator point to blue and the color of the selected indicator point to orange, we can use the following code:

<swiper>
  <swiper-item>
    <image></image>
  </swiper-item>
  <swiper-item>
    <image></image>
  </swiper-item>
  <swiper-item>
    <image></image>
  </swiper-item>
</swiper>

It should be noted that if If we want to implement a gradient color indicator point, we can set the gradient color in the indicator-color attribute or indicator-active-color attribute. The sample code is as follows:

  indicator-color="linear-gradient(90deg, rgba(255,178,51,0.5), rgba(255,102,102,0.8)))" 
  indicator-active-color="linear-gradient(90deg, rgba(255,178,51,0.8), rgba(255,102,102,1)))"

3. Summary

Through this article Introduction, we learned how to use the indicator point component in uniapp, and learned how to modify the color of the indicator point to achieve better visual effects.

In actual development, indicator points are often used together with the swiper component to make the carousel more beautiful and friendly. At the same time, we can also flexibly modify the color of the indicator points according to actual needs to adapt to different scenes and styles.
