Hey, I have two elements button and input, like so:
<input type="button" value="Upload file" onclick={upload_clicked_callback} />
<input type="file" id="file_input" style="display: none;" onchange={file_picked_callback}/>
File input is hidden and triggered programmatically on button click with upload_clicked_callback() which calls function below.
fn on_upload_file_clicked() {
log!("Upload clicked!");
let window = web_sys::window().expect("should have a window in this context");
let document = window.document().expect("window should have a document");
let file_input_elem = document
.get_element_by_id("file_input").expect("File input element with id \"file_input\" should exist.");
let file_input_elem = file_input_elem.dyn_into::<HtmlInputElement>()
.expect("Element should be an HtmlInputElement");
log!("Before click");
file_input_elem.click();
log!("After click");
}
When I click button, an on_upload_file_clicked() starts executing and everything is fine until a simulated click file_input_elem.click();. Simulated click leads to a throw that states "Uncaught Error: closure invoked recursively or destroyed already". (screenshot attached)
Any idea what can be a cause of this? All callbacks are created with use_callback:
let upload_clicked_callback = use_callback(move |e:MouseEvent, _| {
e.stop_propagation();
on_upload_file_clicked();
}, ());
let file_picked_callback = use_callback(move |e: Event, _| {
let input = e.target_unchecked_into::<HtmlInputElement>();
if let Some(files) = input.files() {
if let Some(file) = files.item(0) {
on_file_picked(File::from(file));
}
}
}, ());
