How to get element by innerText

Question

How to get tag in html page  if I know what text tag contains  E g     lt a     gt SearchingText lt  a gt

While it s possible to get by the inner text  I think you are heading the wrong way   Is that inner string dynamically generated  If so  you can give the  tag a class or -- better yet -- ID when the text goes in there   If it s static  then it s even easier

You can use a TreeWalker to go over the DOM nodes  and locate all text nodes that contain the text  and return their parents    x000D   x000D  const findNodeByContent    text  root   document body    gt    x000D    const treeWalker   document createTreeWalker root  NodeFilter SHOW TEXT   x000D   x000D    const nodeList       x000D   x000D    while  treeWalker nextNode      x000D      const node   treeWalker currentNode  x000D   x000D      if  node nodeType     Node TEXT NODE  amp  amp  node textContent includes text     x000D        nodeList push node parentNode   x000D        x000D       x000D   x000D    return nodeList  x000D    x000D   x000D  const result   findNodeByContent  SearchingText    x000D   x000D  console log result   x000D   lt a     gt SearchingText lt  a gt  x000D   x000D   x000D

Using the most modern syntax available at the moment  it can be done very cleanly like this   for  const a of document querySelectorAll  a        if  a textContent includes  your search term          console log a textContent          Or with a separate filter       document querySelectorAll  a        filter a   gt  a textContent includes  your search term        forEach a   gt  console log a textContent     Naturally  legacy browsers won t handle this  but you can use a transpiler if legacy support is needed

Functional approach  Returns array of all matched elements and trims spaces around while checking   function getElementsByText str  tag    a       return Array prototype slice call document getElementsByTagName tag   filter el   gt  el textContent trim       str trim         Usage  getElementsByText  Text here       second parameter is optional tag  default  a     if you re looking through different tags i e  span or button  getElementsByText  Text here    span    getElementsByText  Text here    button      The default value tag    a  will need Babel for old browsers

I ve just needed a way to get the element that contains a specific text and this is what I came up with   Use document getElementsByInnerText   to get multiple elements  multiple elements might have the same exact text   and use document getElementByInnerText   to get just one element  first match    Also  you can localize the search by using an element  e g  someElement getElementByInnerText    instead of document   You might need to tweak it in order to make it cross-browser or satisfy your needs   I think the code is self-explanatory  so I ll leave it as it is    x000D   x000D  HTMLElement prototype getElementsByInnerText   function  text  escape    x000D      var nodes    this querySelectorAll       x000D      var matches       x000D      for  var i   0  i  lt  nodes length  i      x000D          if  nodes i  innerText    text    x000D              matches push nodes i    x000D            x000D        x000D      if  escape    x000D          return matches  x000D        x000D      var result       x000D      for  var i   0  i  lt  matches length  i      x000D          var filter   matches i  getElementsByInnerText text  true   x000D          if  filter length    0    x000D              result push matches i    x000D            x000D        x000D      return result  x000D     x000D  document getElementsByInnerText   HTMLElement prototype getElementsByInnerText  x000D   x000D  HTMLElement prototype getElementByInnerText   function  text    x000D      var result   this getElementsByInnerText text   x000D      if  result length    0  return null  x000D      return result 0   x000D    x000D  document getElementByInnerText   HTMLElement prototype getElementByInnerText  x000D   x000D  console log document getElementsByInnerText  Text1     x000D  console log document getElementsByInnerText  Text2     x000D  console log document getElementsByInnerText  Text4     x000D  console log document getElementsByInnerText  Text6     x000D   x000D  console log document getElementByInnerText  Text1     x000D  console log document getElementByInnerText  Text2     x000D  console log document getElementByInnerText  Text4     x000D  console log document getElementByInnerText  Text6     x000D   lt table gt  x000D       lt tr gt  x000D           lt td gt Text1 lt  td gt  x000D       lt  tr gt  x000D       lt tr gt  x000D           lt td gt Text2 lt  td gt  x000D       lt  tr gt  x000D       lt tr gt  x000D           lt td gt  x000D               lt a href     gt Text2 lt  a gt  x000D           lt  td gt  x000D       lt  tr gt  x000D       lt tr gt  x000D           lt td gt  x000D               lt a href     gt  lt span gt Text3 lt  span gt  lt  a gt  x000D           lt  td gt  x000D       lt  tr gt  x000D       lt tr gt  x000D           lt td gt  x000D               lt a href     gt Special  lt span gt Text4 lt  span gt  lt  a gt  x000D           lt  td gt  x000D       lt  tr gt  x000D       lt tr gt  x000D           lt td gt  x000D              Text5 x000D               lt a href     gt Text6 lt  a gt  x000D              Text7 x000D           lt  td gt  x000D       lt  tr gt  x000D   lt  table gt  x000D   x000D   x000D

I think you ll need to be a bit more specific for us to help you    How are you finding this  Javascript  PHP  Perl  Can you apply an ID attribute to the tag    If the text is unique  or really  if it s not  but you d have to run through an array  you could run a regular expression to find it  Using PHP s preg match   would work for that   If you re using Javascript and can insert an ID attribute  then you can use getElementById  id    You can then access the returned element s attributes through the DOM  https   developer mozilla org en DOM element 1

To get the filter method from user1106925 working in  lt  IE11 if needed  You can replace the spread operator with       slice call document querySelectorAll  a     and the includes call with a textContent match  your search term    which works pretty neatly      slice call document querySelectorAll  a        filter a   gt  a textContent match  your search term        forEach a   gt  console log a textContent
