Hello,

I am trying to create buttons for corresponding fields that when clicked will remove the fields and replace the fields with the fields below.

I have placed this javascript in a button under "run a javascript" when "mouse up"

var idNumber = event.target.name.replace("Delete", "");
for(var i = (parseInt(idNumber)); i <= 40; ++i) {
this.getField("ID"+(parseInt(idNumber)+(i)-1)).value = this.getField("ID"+(parseInt(idNumber)+(i))).value;
this.getField("Desc"+(parseInt(idNumber)+(i)-1)).value = this.getField("Desc"+(parseInt(idNumber)+(i))).value;
this.getField("No"+(parseInt(idNumber)+(i)-1)).value = this.getField("No"+(parseInt(idNumber)+(i))).value;
this.getField("Unit"+(parseInt(idNumber)+(i)-1)).value = this.getField("Unit"+(parseInt(idNumber)+(i))).value;
this.getField("Price"+(parseInt(idNumber)+(i)-1)).value = this.getField("Price"+(parseInt(idNumber)+(i))).value;
this.getField("Total"+(parseInt(idNumber)+(i)-1)).value = this.getField("Total"+(parseInt(idNumber)+(i))).value;
}

 

 I have done some tests and it seems that the problem is with thee "i" variable
can someone please help me with this problem

Thank you all kindly in advance!

Correct answer Bernd Alheit

Something like this:

var idNumber = parseInt(event.target.name.replace("Delete", ""));
for (var i = idNumber; i < 40; i++) {
  this.getField("ID" + i).value = this.getField("ID" + (i + 1)).value;
  ..
}
var i = 40;
this.getField("ID" + i).value = "";
...

So you want to delete the values in the first row?

@try67 
I want to replace the field with the field below it (Like in the poorly drawn picture).

The goal is to have a button next to every row so that when pressed all of the fields will move up into the field before it. It replaces the values with the fields below it and then the fields under that will be replaced and so on.

Yes, I understood. But that means the values in the first row will be deleted...

What field names does you use?

@Bernd Alheit 
The field names are a word plus a number that ranges from 1- 40. so the first columns all the words are
"ID1", "Desc1", "No1", "Unit1", "Price1" "Total1", 
and at the last column the fields are 

"ID40", "Desc40", "No40", "Unit40", "Price40" "Total40", 
The corresponding Button is labelled "Delete"+(1-40)

EDIT: I meant ROWS, not Columns!
