Question

I have this bit of JavaScript…

 15   $('.ajax_edit_address').each(function() {
 16     $(this).ajaxForm({
 17       target: $(this).parents('table.address').find('tr.address_header').children(':first'),
 18       success: function(response) {
 19         $('input, select, textarea', '.ajax_edit_address').removeClass('updating');
 20       }
 21     });
 22   });

That’s formatted the way I like it. But let’s say I had just finished typing something and I wanted to tidy it up. So I run the Vim code formatter on it…

The result is…

 15   $('.ajax_edit_address').each(function() {
 16       $(this).ajaxForm({
 17 target: $(this).parents('table.address').find('tr.address_header').children(':first'),
 18 success: function(response) {
 19 $('input, select, textarea', '.ajax_edit_address').removeClass('updating');
 20 }     
 21 }); 
 22       });

Vim seems to have trouble with functions as method arguments.

Here is what I think is the relevant part of my .vimrc…

:set cindent shiftwidth=2

" indent depends on filetype
:filetype indent on

:filetype plugin on

Is there something else that needs to be installed or configured to format JS code?

Answer 1

The biggest issue seems to be the cindent doesn’t recognize this type of syntax:

test({
  var b = 2;
});

It will turn it into this:

test({
    var b = 2;
    });

If you handle that case I’d imagine the indent wouldn’t be so awful for the jQuery syntax. But this would require you writing a custom javascript indent file. Also, you’d have to edit the html indent file to not use cindent for script tags with javascript content.

I don’t think anyone has successfully created a jquery/prototype compatible indent file for javascript. The existing javascript indent scripts are all flawed.
