How does HTML make an expression submit, point back/return, and retain the form data?
If page A is a form, you can return the form a (unchanged) of the data that was filled in B when the submission goes to error page B for some reason.
Form A, all you want to keep is using class=savehistory
< HTML >
< head >
< META NAME = "save" CONTENT = "History" >
< STYLE >
. savehistory {Behavior:url (#default #savehistory);}
</STYLE >
< BODY >
< FORM name =a >
< INPUT class =savehistory type =text ID =opersistinput >
</FORM >
</Body >
</HTML >
---------------------------------------------------------------
Note: Name=save content=history must be set in meta
The above code ensures that form a (data does not change), the back function can be implemented using History.back () or History.go (-1) in error page B, for example:
<input Type=button value=back onclick=history.back () >
<input Type=button value=back onclick=history.go ( -1) >
