I add "option"s to "select" with javascript or jquery.
I would like to select last added and scroll the scrollbar to most bottom.
i add text like this
function ConsoleOutputAdd(text){
var content = '<option>'+ text +'</option>';
$consoleoutput.append(content);
}
this is the select element.
<select id="consoleoutput" size="4">></select>
i think it would be with onchanged event but i cant think anything more.
thank you
$('#consoleoutput').find('option:last').prop('selected', true );
这是一个小提琴
You can select the last item in the list like so:
var sel = document.getElementById('consoleoutput');
sel.selectedIndex = sel.options.length - 1;
1: write an on-change listener to your select element
$('#consoleoutput').change(function(){
// scroll
})
2: add this to select the option you have added:
$("#consoleoutput").val(text);
