Who can know that the js code below-CodePudding

 function SomeFunction1 (toList, tnIndex tnRelativePos) {
Var lnDestIndex=tnIndex + tnRelativePos; 
Var loOption; 
If (tnRelativePos==0) return; 
If (lnDestIndex>=0 & amp; & LnDestIndexLoOption=toList [tnIndex]; 
If (lnDestIndexFor (var lnIndex=tnIndex; LnIndex> LnDestIndex; LnIndex -) 
ToList [lnIndex]=toList [lnIndex - 1); 
} else {
For (var lnIndex=tnIndex; LnIndexToList [lnIndex]=toList [lnIndex + 1]; 
} 
ToList [lnDestIndex]=loOption; 
} 
}

It looks as if is named column data

The

refer to the original poster song song KING reply:

If (lnDestIndex>=0 & amp; & LnDestIndexLoOption=toList [tnIndex]; 
If (lnDestIndexFor (var lnIndex=tnIndex; LnIndex> LnDestIndex; LnIndex -) 
ToList [lnIndex]=toList [lnIndex - 1); 
} else {
For (var lnIndex=tnIndex; LnIndexToList [lnIndex]=toList [lnIndex + 1]; 
} 
ToList [lnDestIndex]=loOption; 
} 
}

Method parameters 1 array, 2 element coordinate of the need to move after 3 mobile location,

Is tnIndex coordinate element in the array, mobile tnRelativePos new coordinates, negative forward, positive backward-shift, other elements the order unchanged,
