javascript - Why does this dynamically created element not bound to an event? -


http://jsfiddle.net/fe3hnh4x/

<div class="text">(some text...)</div>     var text = $(".text").text();    var excerpt = '';     if(text.length > 100) {         console.log(text.length);          excerpt = text.substr(0, 100);             $(".text").html(excerpt + "<div class='readmore'><a href='#'>read more</a</div>");     }      $(".readmore").on('click', function() {        $(".text").html(text +  "<div class='showless'><a href='#'>show less</a></div>");     });      $(".showless").on('click', function() {        $(".text").html(excerpt +  "<div class='readmore'><a href='#'>read more</a></div>");     });

i trying make excerpt of text using javascript. when "read more" clicked, , whole text , "show less" displayed. , when "show less" clicked, excerpt , "read more" shows again. "show less" not trigger event, "read more" seems work. why?

try this:

   $(document).on('click', ".showless", function () {        $(".text").html(excerpt + "<div class='readmore'><a href='#'>read more</a></div>");    });
