check if the link contains a string and add the rel='sponsored' attribute to it-CodePudding

i have to add attribute rel="sponsored" to all link in page that contain dnlink string. I used the follow code but it doesn't work ...

$("a").each(function() {
   link = $(this).attr("href")
   if(link.indexOf("dnlink") > -1) {
        $(this).attr("rel","sponsored");
   } 
 });

where is the issue?

CodePudding user response：

You haven't declared link correctly.

Your code before I've submitted this answer:

link = $(this).attr("href")

Should be:

const link = $(this).attr("href");

Look at this:

$("a").each(function() {
  const link = $(this).attr("href");
  if (link.includes("dnlink")) {
    $(this).attr("rel", "sponsored");
    $("div").html(link);
  }
});
