jquery - Why remove delete everything? -


why if take off comment page doesn't show p elements anymore?

<body>     <div>         <p>content</p>     </div>      <script src="https://code.jquery.com/jquery-2.1.3.min.js"></script>     <script>         <!--             (var = 0; < 10; i++) {                 var $p = $("div > p:last-child");                 $p.clone().attr("nome", "p_" + i).text("nome p_" + i).appendto($p);                  /*                 if (i == 9) {                     $("div > p:first-child").remove();                 }                 */             }         //-->     </script>

your div has 1 immediate p child, append other p elements to.

so these identical:

$("div > p:last-child"); $("div > p:first-child");

when this:

$("div > p:first-child").remove();

… you've removed appended to:

$("div > p:last-child");

if don't want behavior, append new p elements div itself:

$p.clone().attr("nome", "p_" + i).text("nome p_" + i).appendto('div');
