Question

Within a selector, how do I check if a value of an attribute contains ‘a’, ‘b’, or ‘c’ in a single line? Can you do for example: $('input[name]=a|b|c')? Well, I tested that and it didn’t work.

If nothing but a regex will do, you can try using .filter():

$('#somecontainer input').filter( function(){
  return this.name.match(/a|b|c/);
});

Another of the many ways to do this is to assemble a jQuery object with .add(). And if you really mean contains rather than equals, don’t forget to use name*=a.

$('input[name*=a]')
  .add('input[name*=b]')
  .add('input[name*=c]')
  .add('<p>something</p>') // you can .add() almost anything. useful.
