Hello forums !!
How to increment the value on each function call ?
Suppose i had a function called
addRow()

Code: Select all

//js code
addRow(row)
{
var i = 0;
alert(i);
}
suppose this function is called with onclick event of button.
when clicked first time it should alert 0, 2nd time => 2 3rd time => 3..
I hope you got my question, awaiting for your valueable help.
Thanks in advance to all of you

  1. Declare the variable outside of the function
  2. increment the variable inside the function
