How to pass a variable in form action url in vuejs

I am trying to pass a variable url in form action but couldn’t do so with the following code:

<form action="${url}/auth/login_student" method="POST">
....</form>

And in script tag

export default {
  data() {
    return{
        url: "http:5000/localhost"
    }
  }
}

>Solution :

You have to use v-bind to set action to a JavaScript expression. You can then use a template string.

<form :action="`${url}/auth/login_student`" method="POST">
      ^        ^                         ^
