javascript - getting the sum using footerdata on jqgrid

Question

I have a column name Total.
And I'm also using the footer
value of the jqgrid.

Example this is the column

Total
100
-98
-76
98
76

how can I get the sum of the row
using the footer data.

here is my code.
note: if i use 'sum' it gives me 'NaN'
value.

var parseTotal= grid.jqGrid('getCol', 'Total', false, 'sum');
grid.jqGrid('footerData', 'set', { Total: parseTotal});

Answer 1

You should post more full code which reproduce the problem. I tried some options: the input data as string, the data as integers, using formatter: "integer", using no formatters and so on.

I found no input data of no column definition which produce the described results. Look at the demo

which works and compare with your non working demo. I hope you will find the error in your code.
