Uniapp is a cross-platform front-end framework that can easily develop applications for multiple platforms such as iOS, Android, and Web. During the development process of Uniapp, we often need to use image arrays to render pages, so how to implement Uniapp's image array return? Below, let’s analyze it step by step.
First, we need to define an image folder in thestatic
directory of the Uniapp project, and place the image folder we need to use in this folder picture of. For example:
static/ images/ 1.png 2.png 3.png ...
Here, we take theimages
folder as an example. There are many pictures in the folder.
Next, we need to create an image array in the JS file and add the path of the image to the array. For example:
Here, we create an images array in data and add the path of the image to the array. In the page, we use v-for to loop the array and render the path to the page through the :src attribute.
Of course, we can also use require to introduce image paths. For example:
Here, we use require to introduce images into the array, so that we can create an image array more concisely and quickly.
If we need to use a large number of images on the page, it will be very troublesome to manually add them one by one to the array. At this time, we can use a for loop to dynamically create an image array. For example:
Here, we use a for loop to dynamically create an image array. First, create an empty array in data, then use a for loop and require to introduce images, and add the image path to the array. Finally, assign the array to images, and use v-for to loop the array on the page to render the images on the page.
In general, how Uniapp returns an image array can be implemented in the above ways. Whether you manually add image paths one by one, or use a for loop to dynamically create an array, as long as you master the method, you can create an image array simply and quickly.
