Js gradient display gradient disappears

 

The following is the gradient js Code (indicating that the remaining three lines need to be hidden, click "more" to show the remaining lines, and click "less" to gradually hide them ):

Function showAccomplishmentTableRow (){
$ ("# Accomplishmenttable tr: hidden"). first (). show (2000, function (){
ShowAccomplishmentTableRow ();
});
If ($ ("# accomplishmenttable tr: hidden"). size () = 0 ){
$ ("# Accomplishmenttable"). next (). attr ("onclick", "hideAccomplishmentTableRow ()"). text ("Less ");
}
}
Function hideAccomplishmentTableRow (){
If ($ ("# accomplishmenttable tr: visible"). size () <= 3 ){
$ ("# Accomplishmenttable"). next (). attr ("onclick", "showAccomplishmentTableRow ()"). text ("More ");
Return;
}

$ ("# Accomplishmenttable tr: visible"). last (). hide (2000, function (){
HideAccomplishmentTableRow ();
});

}
