Using VueJS to determine if a certain string includes a specific substring within an if-statement embedded within a v

I am aiming to verify if the link in a json object contains 'http'. If it does, I want to assign a target='_blank' attribute to the v-btn. The link could also be something like #test.

Currently, this is how I am attempting to achieve it:

<v-btn
color="primary"
text
:href="x.link"
x.link.includes("http") ? target="_blank" : null
>
    Read more
</v-btn>

However, I encounter this error message pointing to the first double quote after http: 

error: Parsing error: unexpected-character-in-attribute-name

This is an example of what x looks like:

0:Object
created_at:null
header:"Sport"
id:1
image_large:"https://i.picsum.photos/id/389/800/400.jpg"
image_medium:"https://i.picsum.photos/id/389/600/300.jpg"
image_small:"https://i.picsum.photos/id/389/200/200.jpg"
link:"http://example.com"
submenu:null
updated_at:null

Some objects have a link like link:"#test"

The issue arises with .includes but I haven't found a solution or workaround yet.

I hope my request is clear. Thank you for your assistance.

Answer №1

The issue here is that JavaScript syntax is being injected directly into the "HTML", causing it to be misinterpreted. Instead of not declaring any target and setting target to an empty string, you can use the standard :attribute format to alternate between "_blank" and "":

<v-btn
  color="primary"
  (... other things)
  :target="x.link.includes('http') ? '_blank' : ''"
>

(It's important to note the use of single quotes within the actual JS code.)
