HtmlElementCollection heCol = tab.FindElementsByTags("input:checkbox");
        
HtmlElement he = heCol.Elements[heCol.Count-1];        
            
int index = heCol.IndexOf(he);

PHP	Copy Code
$instance->ClearCookie(); $tab = $instance->MainTab; if (($tab->IsVoid) \|\| ($tab->IsNull)) return -1; if ($tab->IsBusy) $tab->WaitDownloading(); $tab->Navigate("lessons.zennolab.com"); if ($tab->IsBusy) $tab->WaitDownloading(); $heCol = $tab->FindElementsByTags("input:checkbox"); $he = $heCol->Elements[$heCol->Count-1]; $index = $heCol->IndexOf($he);

PHP

Copy Code

$instance->ClearCookie();
 
$tab = $instance->MainTab;
if (($tab->IsVoid) || ($tab->IsNull)) return -1;
if ($tab->IsBusy) $tab->WaitDownloading();
$tab->Navigate("lessons.zennolab.com");
if ($tab->IsBusy) $tab->WaitDownloading();
 
$heCol = $tab->FindElementsByTags("input:checkbox");
        
$he = $heCol->Elements[$heCol->Count-1];
