Dropdown Reset Javascript
To reset dropdown/ or selectbox, we can simply fire this javascript code on any dom event document.getElementById("id_of_selectbox").selectedIndex = -1; The selectedIndex method of javascript will reset the index of the selected dropbox. Another and better option is to create a simple function say resetDropbox and call it where-ever you want in your page. function(id_of_dropbox){ document.getElementById(id_of_dropbox).selectedIndex = -1; } Sometime we face problems, when press back button in browser and we get some value pre-selected in dropbox. We can use binding reset scripts on jQuery's Dom Ready , that will put dropbox of the form in its normal(unselected state).
