Using .each function to take a value, then edit and put the result in other objet propery-CodePudding

I'm trying to make a script that take the URL of the "img src" then edit and finally put it on "a data-title= href", all them on each "item-foo item-bar item-foo bar" The edition works and I get the link but then I can't make the change I Try to do an "each" inside another "each" but it doesn't work, next try to return with the variable "video" but only the last one comes out.

I hope to explain myself well, English unfortunately is not my native language and on top of that I am learning javascript by kicks haha. My regards and respects.

      index = edit2.indexOf("mp4");

CodePudding user response：

To find the containing <a> you can use .closest('a') and then set the .attr()

jQuery("span.image img").each(function() {
  direccion = $(this).prop("src").replace("thumbs", "media").replace("thumbs", "videos");
  $(this).closest('a').attr('href',direccion.slice(0, direccion.indexOf("mp4")   3));
});
