Question

I use laravel 9 and i have a registration form and submit button for some reason doesn't work in mobile phone only, but its working fine in desktop. Any idea what wrong? Thankyou!
Html (blade):
<form action="{{ route('jokibukti') }}" method="POST">
#csrf
<td width="25%">{{ $item->keterangan }} <input type="text"
id="ketbaru" name="keteranganbaru" class="form-control"
placeholder="Masukan Bonus Disini!"></td>
{{-- <td width="7%"><a class="btn btn-primary btn-sm" onclick=''>Selesai</a> --}}
<td width="25%">
<input type="hidden" name="id" value="{{ $item->id }}">
<label class="">
<span class="sr-only">Pilih Gambar</span>
<input type="file" name="image" class="" />
#error('image')
<span class="text-red-600 text-sm">{{ $message }}</span>
#enderror
</label>
<button type="submit" value="submit" class="btn btn-primary btn-sm">Submit</button>
</form>
Route :
Route::post('/joki/bukti', [ControllerJoki::class, 'buktiselesai'])->name('jokibukti');
Controller :
public function buktiselesai(Request $request)
{
// #dd($request->image);
$this->validate($request, [
'image' => 'required|image|mimes:jpg,png,jpeg,gif,svg|max:2048',
]);
$ketbaru = $request->keteranganbaru;
$ketlamauser = Jokiongoing::where('id', $request->id)->first();
$ketlama = $ketlamauser->keterangan;
if ($ketlama != "") {
$keterangan = $ketlama . " & " . $ketbaru;
} else {
$keterangan = $ketbaru;
}
// $image_path = $request->file('image')->store('buktijoki', 'public');
$imageName = time() . '.' . $request->image->extension();
$request->image->move(public_path('buktijoki'), $imageName);
$data = Jokiongoing::where('id', $request->id)->update([
'bukti' => $imageName,
'keterangan' => $keterangan,
'acc' => '1',
]);
if ($data) {
return redirect()->route('jokiaktif')->with(['success' => 'Bukti Berhasil disimpan']);
} else {
return redirect()->route('jokiaktif')->with(['error' => 'Bukti Gagal Disimpan']);
}
}
<script>
var tap = true;
document.addEventListener('touchstart', function(e) {
tap = true;
});
document.addEventListener('touchmove', function(e) {
tap = false;
});
document.addEventListener('touchend', function(e) {
if (tap) {
//users tapped the screen
}
});
</script>
Trying adding this script from someone in the stackoverflow, but get nothing as result.
Im try to add onClick to the button
<button onClick = "testsubmit()" value="submit" class="btn btn-primary btn-sm">Submit</button>
<script>
function testsubmit() {
alert("masuk");
}
</script>
and its work fine, what happen to type="submit" ?
