wire:dirty

The wire:dirty directive shows or hides elements based on whether form data has been modified but not yet synced to the server. This provides instant visual feedback to users about unsaved changes, helping prevent data loss and improving the form experience.

Basic Usage

This contact form demonstrates wire:dirty with unsaved change indicators and targeted property tracking:

BoxLang

// wires/ContactForm.bx
class extends="cbwire.models.Component" {
    data = {
        "name": "",
        "email": "",
        "message": ""
    };

    function submit() {
        // Save form data
        sleep(1000);
        // Form is now synced
    }
}

CFML

// wires/ContactForm.cfc
component extends="cbwire.models.Component" {
    data = {
        "name" = "",
        "email" = "",
        "message" = ""
    };

    function submit() {
        // Save form data
        sleep(1000);
        // Form is now synced
    }
}

BoxLang

<!-- wires/contactForm.bxm -->
<bx:output>
<form wire:submit="submit">
    <input type="text" wire:model="name" wire:dirty.class="border-yellow-500" placeholder="Name">
    <div wire:dirty wire:target="name">Name has unsaved changes...</div>
    
    <input type="email" wire:model="email" placeholder="Email">
    
    <textarea wire:model="message" placeholder="Message"></textarea>
    
    <button type="submit">Submit</button>
    
    <div wire:dirty>You have unsaved changes. Click submit to save.</div>
    <div wire:dirty.remove>All changes saved!</div>
</form>
</bx:output>

CFML

<!-- wires/contactForm.cfm -->
<cfoutput>
<form wire:submit="submit">
    <input type="text" wire:model="name" wire:dirty.class="border-yellow-500" placeholder="Name">
    <div wire:dirty wire:target="name">Name has unsaved changes...</div>
    
    <input type="email" wire:model="email" placeholder="Email">
    
    <textarea wire:model="message" placeholder="Message"></textarea>
    
    <button type="submit">Submit</button>

What wire:dirty Does

When you add wire:dirty to an element, CBWIRE automatically:

• Tracks Form Changes: Monitors when form inputs differ from server-side values

• Shows Elements: Displays elements when data properties have unsaved changes

• Hides When Synced: Removes elements after data is synchronized with the server

• Integrates with wire:model: Works seamlessly with two-way data binding

Available Modifiers

The wire:dirty directive supports these modifiers:

• Remove: .remove - Inverts behavior, showing element when data is synced

• Class: .class - Toggles CSS classes instead of showing/hiding elements

Combine with wire:target to track specific properties: wire:dirty wire:target="name"

Use wire:dirty with forms to provide clear feedback about unsaved changes and prevent accidental data loss.
