Select element by exact match of its content

Question

All right  I wonder if there is a way to make the  contains   jQuery s selector to select elements with only the string that is typed in  for example -   lt p gt hello lt  p gt   lt p gt hello world lt  p gt      p contains  hello     css  font-weight    bold      The selector will select both p elements and make them bold  but I want it to select only the first one

No  there s no jQuery  or CSS  selector that does that   You can readily use filter      p   filter function         return   this  text        hello      css  font-weight    bold      It s not a selector  but it does the job   -   If you want to handle whitespace before or after the  hello   you might throw a   trim in there   return   trim   this  text         hello     For the premature optimizers out there  if you don t care that it doesn t match  lt p gt  lt span gt hello lt  span gt  lt  p gt  and similar  you can avoid the calls to   and text by using innerHTML directly   return this innerHTML      hello        but you d have to have a lot of paragraphs for it to matter  so many that you d probably have other issues first   -

Like T J  Crowder stated above  the filter function does wonders  It wasn t working for me in my specific case  I needed to search multiple tables and their respective td tags inside a div  in this case a jQuery dialog         MyJqueryDialog table tr td   filter function             The following implies that there is some text inside the td tag      if    trim   this  text        Hello World                Perform specific task              I hope this is helpful to someone

You can use jQuery s filter   function to achieve this      p   filter function        Matches exact string    return   this  text        Hello World      css  font-weight    bold

An one-liner that works with alternative libraries to jQuery      p   filter  i  p    gt    p  text   trim        hello   css  font-weight    bold      And this is the equivalent to a jQuery s a contains  pattern   selector   var res      a   filter  i  a    gt    a  text   match  pattern

I found a way that works for me  It is not 100  exact but it eliminates all strings that contain more than just the word I am looking for because I check for the string not containing individual spaces too  By the way you don t need these      jQuery knows you are looking for a string  Make sure you only have one space in the  contains    part otherwise it won t work    lt p gt hello lt  p gt   lt p gt hello world lt  p gt     p contains hello  not  contains       css  font-weight    bold      And yes I know it won t work if you have stuff like  lt p gt helloworld lt  p gt

Try add a extend pseudo function     expr      textEquals     expr createPseudo function arg        return function  elem             return   elem  text   match       arg                      Then you can do      p textEquals  Hello World

So Amandu s answer mostly works  Using it in the wild  however  I ran into some issues  where things that I would have expected to get found were not getting found  This was because sometimes there is random white space surrounding the element s text  It is my belief that if you re searching for  Hello World   you would still want it to match    Hello World      or even  Hello World  n   Thus  I just added the  trim    method to the function  which removes surrounding whitespace  and it started to work better   Specifically       expr      textEquals   function el  i  m        var searchText   m 3       var match     el  text   trim   match       searchText            return match  amp  amp  match length  gt  0      Also  note  this answer is extremely similar to  Select link by text  exact match   And secondary note    trim only removes whitespace before and after the searched text  It does not remove whitespace in the middle of the words  I believe this is desirable behavior  but you could change that if you wanted
