I have:

var rows = $table.find('tbody > tr').get();

This selects all rows. However, not all tables have thead and tbody explicitly defined, so 开发者_如何学JAVAI need to filter out any rows that have .children('th')


EDIT: I'm assuming you wanted to filter out the rows that have <th> elements. If you wanted to end up with only those rows, then just get rid of the :not() part.


This will give you <tr> elements in the table that do not have a descendant <th>.

var rows = $table.find('tr:not(:has(th))').get();
  • http://api.jquery.com/not-selector/
  • http://api.jquery.com/has-selector/

Note that this will also give consideration to nested tables. If there will be nested tables with <th> tags, try this:

var rows = $table.find('tr:not(:has( > th))').get();

...which should limit the consideration of the <th> tags to immediate children.


Why not change that to:

var rows = $table.find('tr > th').get();

EDIT:

var rows = $table.find("tr:has(th)").get();
