javascript - jQuery Each function iterates over everything despite if statement -


the code appends page url after clicking specific links on page. when run code, performs expected, appending url links match code. however, when print console, noticed appeared every single link on page, despite if statement supposed limit it. when took if statement out, code functioned same. however, though works, want make more efficient , run on links match parameters.

 // function change link adding current page  function setslatelink() {      // url of current page      var currentpage = document.location.href;      // url of slate      var slatelink = jquery('a[href$="code=magic"]').attr("href");      // rewrite slate, adding query string key slate , value of current page      console.log("processing link change");      return slatelink += "&sys:interaction:summary=" + currentpage;   }   jquery(document).ready(function() {       jquery("a").each(function(i, item) {          // if there tag, check ends          if (jquery(i == 'a[href$="code=magic"]')) {              console.log("found link: " + jquery("a").attr("href"));              // change link set referrer (current page) in url              jquery('a[href$="magic"]').attr("href", setslatelink());              console.log("changed link");          }       });  });

any idea cause this?

use is() determine if element matched selector. http://api.jquery.com/is/

example:

if ($(item).is('a[href$="code=magic"]')) {   // item matches }

but simplify selecting specific tags start with:

$('a[href$="code=magic"]').each(function(i, item) {   // code=magic links... });

going 1 step further...

$('a[href$="code=magic"]').each(function(i, item) {   var href = $(item).attr('href');    $(item).attr('href', href + '&sys:interaction:summary=' + document.location.href); });
