Experiment with catching an exception on variable `v`

In my code, I am using a v-if statement to display an error message in HTML.

<div id="error" v-if="showError">Error User or Password</div>

data() {
  return {
    showError: false,
};}

When I change the value of showError to true in the data object, the error message is displayed as expected.

However, when I try to trigger the error message inside the catch block:

  catch (error) {
    alert('Invalid username or password')
  }

The alert function works correctly, but setting showError = true or showError: true; does not display the error message in HTML as expected.

Any suggestions on how to achieve this functionality?

Answer №1

To successfully reset the member, you should first assign it the value true and then allow some time before changing it back to false. Here's an example implementation:

this.displayError = true;
setTimeout(() => {
    this.displayError = false;
}, 1000);
