Question

How to remove first span element after <input id="mytxt" type="textbox"/> , if it exists?

 $('#mytxt').live('change', function(){
        //TO DO    
 }

Answer 1

Within your live function, do this:

$(this).next("span").remove();

Answer 2

I think you have to check the first "SPAN" element after the element. so you have to go till the end of the document

var element = $(this).next();
while($(element)[0].tagName!="SPAN" && $(element).length!=0){
    element = $(element).next();
}
if($(element)[0].tagName=="SPAN"){
    $(element).remove();
}
