VueJS 换行符未正确呈现

Question

I got the following problem, I read data string from an API which contains new line characters \\n and I want to display them correctly in my template.

But when I do something like:

<p>{{ mytext }}</p>

The text is display with \\n characters in it like normal text.

The text string from the response is in the format of "Hello, \\n what's up? \\n My name is Joe" .

What am I doing wrong here?

Answer 1

Not even a vue issue you could simply use CSS and apply white-space: pre; to the content. You shouldn't need an additional package for this.

 new Vue({ el: '#app', data: { text: 'Hello Vue.\\nThis is a line of text.\\nAnother line of text.\\n' } })

 .pre-formatted { white-space: pre; }

 <script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.15/vue.js"></script> <div id="app"> <div class="pre-formatted">{{ text }}</div> </div>

Answer 2

Use the <pre></pre> tag to pre serve the pre formated text. More info MDN Pre tag docs

 new Vue({ el: '#app', data: { text: 'Hello, \\n what\\'s up? \\n My name is Joe' } })

 <script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.15/vue.js"></script> <div id="app"> <pre>{{ text }}</pre> </div>

Usage

Vue.component('nl2br', Nl2br)

View

<nl2br tag="p" :text="`myLine1\nmyLine2`" />

result :

<p>myLine1<br>myLine2</p>

Answer 4

This is a solution to split string in multiple <div> elements.

I use this also with i18n plugin and I like it because I don't need to touch CSS.

 new Vue({ el: '#app', data: { text: ['Hello Vue.','This is a line of text.','Another line of text.',''] } })

 .pre-formatted { white-space: pre; }

 <script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.15/vue.js"></script> <div id="app"> <div v-for="text of text">{{ text }}</div> </div>
