How to write spaces in vue

In Vue, space processing is divided into ordinary spaces and non-breaking spaces, which can be processed through template interpolation, instructions (v-text, v-html, v-pre) and CSS. Among them, ordinary spaces are standard ASCII space characters, and non-newline spaces are in HTML and will not cause line breaks. Spaces can be used in template interpolation to create gaps, and directives can preserve spaces in HTML. CSS white-space controls the handling of spaces within elements, and v-pre prevents Vue from compiling text content to preserve spaces. You need to be careful to avoid too many spaces. Non-breaking spaces may affect the layout. v-pre is only suitable for predefined text.

Handling of spaces in Vue

In Vue, spaces are a common character and need to be processed correctly. Ensure correct rendering and layout.

Types of spaces

There are two types of spaces in Vue:

• Normal spaces ( ** ): This is the standard ASCII space character, represented by ` in HTML.
• No newline spaces ( /)): This is a special character, represented by ` in HTML, it does not cause Browser wraps.

Using spaces in Vue

The main methods of using spaces in Vue are as follows:

• Spaces in template interpolation: In template interpolation, you can use normal spaces or non-breaking spaces to create gaps:

  <code class="html"><template>
    <p>{{ message }} {{ world }}</p>
  </template></code>

• v-text and v-html Directives: These two directives can preserve spaces in HTML. For example:

  <code class="html"><template>
    <p v-text="message"></p>
    <p v-html="message"></p>
  </template></code>

  Copy after login

• CSS style: You can use the white-space property of CSS to control the processing of spaces within the element, for example:

  <code class="css">.container {
    white-space: nowrap;
  }</code>

  Copy after login

• v-pre directive: This directive can be used to prevent Vue from compiling text content, thus retaining spaces:

  <code class="html"><template>
    <p v-pre>{{ message with spaces }}</p>
  </template></code>

  Copy after login

Points to note

When using spaces, you need to pay attention to the following points:

• Excessive spaces may cause layout confusion.
• When using non-breaking spaces in template interpolation, you need to ensure that it does not affect layout or line wrapping.
• v-pre directive can only be used to retain predefined text, not dynamically generated content.
