Clear value on blur when no item is selected

Hi. When I filter an editable-select and select no item, but a previous item was selected, I 'd like to clear the value (on blur, hide or any where else). Could any one help me?

How about using some brute force :

var comboRef = document.getElementById('yourcomboid'); var isMatch = false; var liElems = comboRef .parentNode.getElementsByTagName("li"); for(var i=0;i<liElems.length;i++){ if(liElems[i].value==comboRef .value){ isMatch = true; break; } } if(!isMatch) comboRef .value='';
