Hi,
In given code, I am adding one row to the table using OnAddClick() function.
OnAddClick() function add one new row to the table, which contains button also.
each time i am generating new button for a new row and adding it to the table. I have assigned a function name GetId() to that button.
On that button click, I am calling GetId() funtion by passing the Id of the button.
It works fine in IE9 but not in Chrome, Opera and Mozilla.
Please give me some suggestions regarding this.
