How can Vue handle parsing a line break within a textarea string retrieved from an Api?

Vue 2 is the framework I am currently working on, and I have encountered an issue with displaying the myText variable in a textarea with line breaks. When using a static variable in the textarea, the line breaks function properly, showing:

line one
line two2

However, when retrieving myText from an API, it displays the \n as text:

line one\nline two2

This issue can be better understood with the following code snippet:

 <template>
  <div class="Test">  
    <textarea name="name" v-model="myText" >   </textarea> 
  </div>
</template>

Here is the related JavaScript code:

 <script>
    export default {
      name: 'Test',
       data: () => ({
          myText: ' line one\nline two2 ' 
       }), 
       created(){
         this.getTextFromApi();
       },
       methods:{
           getTextFromApi(){ 
                ajax()
                 .done(function(Response){ 
                    this.myText = Response.text;   
                 };
           },
      }
    } 
</script>

Now the question arises: How can the textarea interpret the \n received from an API as a line break instead of a text?

Answer №1

It appears that the text in your API contains double backslashes, possibly due to escaping characters like "\n" as "\\n" before entering them into your API. To fix this issue, you can use the following code:

this.myText = Response.text.replace('\\n','\n');

By doing this, the \n will be preserved for line breaks. Additionally, make sure to use an arrow function in the callback like so:

.done((Response) => { 
   this.myText = Response.text.replace('\\n','\n');   
})
