I am using to datatable select plugin and when user presses selectAll button i want to select only n number of records which i've specified.

If you are referring to this example you can use one the row-selector options to select only those rows you wish. If you still need help please provide more information about "i want to select only n number of records which i've specified.".

Here's my custom button that i created, It does work but it takes too much time because it's iterating each entries until max limit is reached.
Hope this code will explain what i am trying to do.

You can refactor that code to make it more efficient:

1. You're counting the rows on each iteration - you only need to do it once and then increment the count yourself.
2. You keep going through the loop even when the max value is reached - you can break out by returning false

This is the code from this example:

  var selectedRows = table.rows({selected:true}).count();
  table.rows().every(function(i) {
    if (max > selectedRows) {
      this.select();
      selectedRows++;
    }
    else {
      return false;
    }    
  })
