How to select an element by full text match (jQuery)?

Question

JavaScript

Have a DOM tree

<elem1><br>
  <child1> 1 </child1><br>
  <child2> 2 </child2><br>
  <child3> 1 1 </child3><br>
</elem1><br>

I need to select a child element that contains exactly "1" (but not "1 1"), so the .contains() operation doesn't work.

Answer 1

$.each and comparing desired string with .text()?

Answer 2

api.jquery.com/contains-selector/ - probably, sometimes you need to get into the API Reference

Answer 3

Write your own filter, it's easy: anton.shevchuk.name/javascript/jquery-for-beginners-filter-extend/
However, this will not be fast anyway, it would be better to use classes or some other attributes to find what you need.
