How to implement line breaks in Uniapp

Uniapp is a cross-platform application development framework developed based on Vue.js, which can be used to develop applications for iOS, Android and Web platforms. In the actual development process, we may encounter situations where multiple lines of text are required, so how to implement line breaks in Uniapp? This article will provide you with some methods.

1. Use the text tag in the view tag

In uniapp, we usually use the view tag to layout the page, and the text tag is used to place text content. Use the text tag in the view tag to automatically wrap the text according to the width of the tag. The specific code is as follows:

<view>
    <text>这是一个很长的文本，需要进行换行展示。</text>
</view>

2. Use the
tag to implement manual line wrapping

If you need to manually wrap the line, you can use the
tag in HTML to achieve it. The specific code is as follows:

<view>这是第一行<br/>这是第二行</view>

3. Use CSS styles

Uniapp supports CSS styles, and we can use styles to wrap multi-line text. The specific code is as follows:

<view class="text-wrap">这是一个需要换行的文本，可以通过CSS样式来实现。</view>

.text-wrap {
    display: -webkit-box;
    -webkit-box-orient: vertical;
    -webkit-line-clamp: 2;
    overflow: hidden;
}

In the above code, -webkit-line-clamp indicates the number of lines to be displayed. Here we set it to two lines. When the text content exceeds two lines, the excess part will be automatically hidden.

Summary

The above three methods can realize line wrapping of multi-line text. Each has its own advantages and disadvantages. You need to choose the appropriate method according to actual needs. The text tag can be used to automatically wrap the line, but manual control of the line wrap position is not supported; the
tag can be used to manually wrap the line, but each line of code needs to be manually written, which is not very flexible. Using CSS styles can better control the line break position and number of lines, but it requires certain CSS knowledge. I hope this article can help you implement line wrapping of multi-line text in Uniapp development.
