// ------------------------------------------------------------------------------------------------------------- ------
Isiebrowser () return value: True (IE) False (NNX)
exist (Fileid) to determine if Fileid already exists
Addinputfile (Spanid,fileid) adds an input file with index number to the element named Spanid
ADDBR (Spanid,brid) adds a newline character with an ID of Brid in the element named Spanid
Adddel (Spanid,index) adds a "delete" to index in the element named Spanid, and he can delete the corresponding input file and BR
Addhidden (Spanid,hiddenid,value) adds an ID of Hiddenid to the element named Spanid, and the value of input Type=hidden

Second,create the Replace element
var temp= document.createelement ("SPAN");
Third,replace it
Span.replacechild (Temp,fileobj);
Span.replacechild (Temp,brobj);
