Question

如果我有以下超文本:

<p> some random text :) video?v=E_LkHrerwe4lnhhnrCbo another video?v=567ghf564_-56e</p>
<p> some2 random2 text2 video?v=rt5y5yvbn5y</p>

Using jQuery how can I get the ID which is 8 characters after video?v= so for the first one the id will be E_LkHrer, then wrap the string with a <span id=" +8charID+ "></span>? Thus, for the HTML above it will return

<p> some random text :) <span id="E_LkHrer">video?v=E_LkHrerwe4lnhhnrCbo</span> another <span id="567ghf56">video?v=567ghf564_-56e</span></p>
<p> some2 random2 text2 <span id="rt5y5yvb">video?v=rt5y5yvbn5y</span> </p>

ATM I have this, but I don t know where to go from there and I know the jQuery doesn t have much to do with what I need I was just testing if I could try stripping an id from one video?v=

$("p").each(function() {
  var content = $(this).html();
  var getwatch = content.split( video?v= );
  $(this).after(getwatch[1].substring(0, 8));
});

Answer 1

$( p ).html(function (_, str) {
  return str.replace(/video?v=([^s<]+)/g, function ($0, $1) {
    return [ <span id=" , $1.substr(0, 8),  "> , $0,  </span> ].join(  );
  });
});
