javascript - HTML Links do not work after AJAX POST -

-

background: working on small web application. ajax post data action(create.php) , create.php execute necessary mysql query. once ajax done, append message div id="container"></div> informing user of successful execution clear content "container" future use; however, here in lies problem.

problem: after ajax executes, can not click on html links loaded onto page(page.php). have refresh page in order click on links , follow them destination. causing happen , how can fix it?

ajax not need return result. needs execute specified jquery code once request done. on hunch, altered create.php echo $_post array , have ajax return result. once ajax loads result "container" still can not click on links loaded on page.php

answer: dom not being reloaded after ajax calls causing bootstrap dropdown menus not function properly. bootstrap dropdown class had manually reinitialized after each call. has been answered in detail here

create.php

<?php if($_post){ //run mysql query }else{ //do nothing } ?>

form.php

<form id="new-items"> <input type="text" name="item" /> <input type="button" onclick="create_item()" name="submit" value="submit" /> </form>

page.php

<html> <head> <script> $(document).ready(function(){   $("#add_items").click(function(){     event.preventdefault();     $("#content").load("form.php");   });  }); function create_item(){     var form_data = $("#new-items").serialize();      var request = $.ajax({         url: "create.php",         type: "post",         data: form_data,     });      request.done(function(){          $("#content").append('<div>user added successfully</div>');         settimeout(function(){             $("#content").fadeout("slow");         }, 5000);         settimeout(function(){             $("#content").empty();         }, 8000);     });      request.fail(function(jqxhr, textstatus) {         alert( "request failed: " + textstatus );     }); } </script> </head> <body> <nav> <a href="link1.php">link1</a> <a href="link2.php">link2</a> <a href="#" id="add_items">add new items</a> </nav> <div id="content"></div> </body> </html>

after fadeout #content element, remains hidden. next time call ajax function, it's loading create.php invisible element.

try:

        settimeout(function(){             $("#content").fadeout("slow", function() {                $(this).empty().show();             });         }, 5000);

other issues: <div class="content"> should <div id="content">; didn't include jquery.js @ top of script; didn't pass event object e click handler.

page.php should like:

<html> <head>     <script src="https://code.jquery.com/jquery-2.1.4.min.js"></script>     <script>     $(document).ready(function(){       $("#add_items").click(function(e){         e.preventdefault();         $("#content").load("form.php");     });   });     function create_item(){         var form_data = $("#new-items").serialize();          var request = $.ajax({             url: "create.php",             type: "post",             data: form_data,         });          request.done(function(){              $("#content").append('<div>user added successfully</div>');             settimeout(function(){                 $("#content").fadeout("slow", function() {                     $(this).empty().show();                 });             }, 5000);         });          request.fail(function(jqxhr, textstatus) {             alert( "request failed: " + textstatus );         });     }     </script> </head> <body>     <nav><a href="#" id="add_items">add new items</a></nav>     <div id="content"></div> </body> </html>
