javascript - Automatically add image to PDF links within WooCommerce product tabs -


within each product page have bunch of tabs , of them contain links other websites , contain pdf links.

what i'd somehow find pdf links within each tab , add following class them: pdf-icon. class have following css:

.pdf-icon::before {   content: url(image.png) " "; }

is there way php or javascript?

btw, site i'm talking http://www.ibisci.com , example product http://www.ibisci.com/product/ib56000b-hr-2025-high-resolution-electrophoresis-dna-start-up-kit. scroll down see product tabs , click on "operation manual".

thanks in advance!

update:

op's page uses jquery tabs. however, links within tab content regular links. method below work, jquery solution might better option.

original:

there many solutions problem. method below basic illustrate 1 method. assumes href url , cycles through links on page looking .pdf extension. these have class applied make them red.

run code snippet test

<html>  <body>  <style type="text/css">      .myclass { color: red; }  </style>       <h2>find pdf links</h2>      <ol>          <li><a href="page1.pdf">example1.pdf</a>         <li><a href="page1.pdf">example2.pdf</a>          <li><a href="page1.html">example3.html</a>       <li><a href="page1.pdf">example4.pdf</a>   </ol>        <script type="text/javascript">           var i, links = document.getelementsbytagname('a');            for(i=0; i<links.length; i++) {          if (links[i].href.match(/.pdf/ig)) links[i].classname = 'myclass';      }        </script>        </body>  </html>

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
