Experiencing issues calling a function in Vue.js while working with the SDK JavaScript?

When attempting to integrate the JavaScript SDK into Vuejs by utilizing a Facebook login button, I encountered an issue:

<template>
  <div>
    <div class="fb-login-button" data-max-rows="1" data-size="large" data-button-type="login_with" data-show-faces="false" data-auto-logout-link="true" data-use-continue-as="false" onlogin="checkLoginState();">
    </div>
   </div>
</template>
<script>
  export default {
   data() {
     return: { }
   },
   methods: {
    checkLoginState: function() {
      console.log("logged")
     }
   }
  }
</script>

Despite implementing this code, I am unable to observe any results. How can I address and rectify this issue?

Answer №1

The reason for this issue is that the Facebook SDK is only aware of functions in the window scope, while your function exists in the local scope. This limitation applies to many other libraries as well. To resolve this, you can bind `this` to the window when creating or mounting the component.

created() {
    window.checkLoginState = this.checkLoginState
}

By doing this, your local component method will be invoked when the onlogin event is triggered by the FB API.

Alternatively, you can explore other binding syntaxes or manually create the button yourself.
