+## Preventing closing the modal on Escape or on click away based on the modal state
+
+When a modal is closed on Escape or click away, `closingModalOnEscape` and `closingModalOnClickAway` are issued. Handle these events to prevent closing a modal based on its state, for example, if there are uncommitted changes.
+
+For example, if a modal has a `isDirty` property, it could have the following handler:
+
+```
+@script
+<script>
+    $wire.on('closingModalOnEscape', data => {
+        if ($wire.isDirty && !confirm('{{ __('You have unsaved changes. Are you sure you want to close this dialog?') }}')) {
+            data.closing = false;
+        }
+    });
+    $wire.on('closingModalOnClickAway', data => {
+        if ($wire.isDirty && !confirm('{{ __('You have unsaved changes. Are you sure you want to close this dialog?') }}')) {
+            data.closing = false;
+        }
+    });
+</script>
+@endscript
+```
