JS (jquery) related methods for operating Arrays

1: The split function splits the string by a specific character and saves the split result to the string array.

 
Function splitusersinformation (users ){
VaRUsersarray = users. Split (';');
ReturnUsersarray;
}
 

2: The substr function is used to cut the target string.

 
Currentstr = currentstr. substr (0, Currentstr. Length-2);
 

3: The Push method adds a record to the array.

VaRTotalusers =NewArray ();
Function pushitem (name, invalid memt ){
VaRCurrentuser =NewObject ();
Currentuser. Username = Name;
Currentuser. Department = Alibaba memt;
Totalusers. Push (currentuser );
}
 

4: The pop method pops up the top record from the array stack.

 VaR Totalusers = New Array ();
 VaR User1 = New Object ();
User1.username = "  Haha  " ;
User1.department = "  Hahahaha  " ;
 VaR User2 = New Object ();
User2.username = "  Lolo  " ;
User2.department = "  Lolololo  " ;
Totalusers. Push (user1 );
Totalusers. Push (user2 );
Totalusers. Pop ();
 //  User1 is left in totalusers, because user2 is displayed at the top of the stack. 

5: The splice method deletes a specified record or multiple records from the array.

 
VaRTotalusers =NewArray ();
Totalusers. Push (...);

Function spliceitem (name ){
For(VaRI =0; I <totalusers. length; I ++ ){
If(Totalusers [I]. Username = Name ){
Totalusers. splice (I,1)
}
}
}
