jQuery add blank option to top of list and make selected to existing dropdown
This worked:
$("#theSelectId").prepend("<option value='' selected='selected'></option>");Firebug Output:
<select id="theSelectId"> <option selected="selected" value=""/> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="mercedes">Mercedes</option> <option value="audi">Audi</option></select>You could also use .prependTo if you wanted to reverse the order:
$("<option>", { value: '', selected: true }).prependTo("#theSelectId");
Solution native Javascript :
document.getElementById("theSelectId").insertBefore(new Option('', ''), document.getElementById("theSelectId").firstChild);
