For starters, I did this to her:
inputEl := (doc.getElementsByName('subent').item(0,0) as IHTMLInputElement);
I did the same with other input strings in order to assign some text to them via " inputEl.value := Текст
".
As far as I understood, I assigned inputEl to that same input as an object. But how to click on the input button, if its name attribute is known?
