JQuery tablesorter custom parser to all headers?

问题

I'm currently working with a tablesorter table in which I need to use a custom parser for each header. I'd like to know if there's an easy way to do this, such as:

table.tablesorter({ 
        headers: { 
            0-20: { 
                sorter:'CareerLast' 
            }, 

        } 
    }); 

I know that the above code doesn't work, but I'm just wondering if there's a more readable way of applying the custom parser, other than manually placing it on each column by index.

回答1:

Well, I think you have three choices:

1. Define each header, 0 through 20 in the initialization options.

   header : {
       0 : { sorter : 'CareerLast' },
       1 : { sorter : 'CareerLast' },
       2 : { sorter : 'CareerLast' },
       // etc
       20 : { sorter : 'CareerLast' }
   }
   

2. Use the meta data plugin and add the sorter definition in the header class:

   // untested, but I think this will work
   $('table').find('thead th').addClass("{sorter:'CareerLast'}");
   $('table').tablesorter();
   

3. Try out my forked version of tablesorter and just add the sorter as a class name

   $('table').find('thead th').addClass('sorter-CareerLast');
   $('table').tablesorter();

return true from 'is' in addParser

eg: this parser assigns 'N/A' a value of -1 $.tablesorter.addParser({ id: 'num-with-na', is: function(s) { //always use this return true; }, format: function(n){ return n === 'N/A' ? -1 : n; }, type: 'numeric' });
