What could be causing the on:click event not to function in Svelte?

I need some assistance with displaying a text input field based on the value of the "changeEmail" variable. I have a handleClick function that toggles the value of "changeEmail" between true and false, but when I click on a button, nothing happens. Any guidance would be greatly appreciated.

  let changeEmail = false;

 function handleClick() {
   console.log(changeEmail)
    changeEmail = !changeEmail;
  }
  $: changeEmail;
</script>

<div class="card">

  <div class="info-column">
    <h2>About</h2>
    <div class="info-field">
      <h4>Name</h4>
      {userModel.firstName} {userModel.lastName}
    </div>
    <div class="info-field">
      <h4>Email</h4>
      {#if changeEmail === false}
        {userModel.email}
      {:else}
        <TextInput placeholder="${userModel.email}"/>
      {/if}
      <Button on:click={handleClick}>Edit</Button>
    </div>
  </div>
</div>

This component resembles the following structure on the page:

<section>

  <PersonalSettingsCard userModel={$user}>

  </PersonalSettingsCard>
</section>

Answer №1

In agreement with H.B.'s statement and written explanation, it is necessary to forward the click event to the Button component. To see this concept applied in a real-world scenario, check out this example from the official tutorial (which I highly recommend completing if you haven't already).

If you want to see the click event in action with a customized <Button>, take a look at my simple REPL demonstration that I put together.

Answer №2

If you encounter no issues (such as userModel being null/undefined), the issue likely lies with your Button component utilizing a native button element, which should function properly.

To ensure the component can be used externally, it must pass on the event.

<!-- Within the Button component -->
<button on:click> ... </button>

Visit the documentation for on:event (refer to section following modifiers)

If the Button component is sourced from a library, verify the available events (though most would typically pass on the click event as expected).
