Trouble with JavaScript: Unable to Hide a Div Element

My goal is to hide the "target" div, but for some reason, it's not working as intended. When I try to hide the div with id "div1" instead of "target," it works fine. Can anyone help me figure out why I can't hide the "target" div?

<html>
<head>
  <title>My example</title>
  <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

  <script type="text/javascript" language="javascript">


     $(document).ready(function() {
        $("#hide").click(function(event){
          var ele = document.getElementById("target");
          ele.style.display = "none";                     
        });
     });                                

    //myItems.length
     $(document).ready(function() {
        $("#driver").click(function(event){
           $.getJSON('http://www.example.com/JSONV5.php', function(jd) {
           var myItems = jd["items"];
              for (i = 0; i < 1; i++) {
                $('#div1').append('<div id="target">');
                $('#div1').append('<p> Title: ' + jd["items"][i]["title"]    + '</p>');
                $('#div1').append('<p> Description: ' + jd["items"][i]["description"]   + '</p>');
                $('#div1').append('<p><img alt="" src=/uploads/' + jd["items"][i]["image1"] + '></p>');
                $('#div1').append('</div>');                       
              };
           });
        });
     });
  </script>

   </head>  
   <body>
     <p>Click on the button to load result.html file:</p>
     <div id="div1" style="background-color:#cc0;">
       My DIV 1
     </div>

     <input type="button" id="driver" value="Load Data" />
     <input type="button" id="hide" value="Hide Data" />
   </body>
</html>

Answer №1

Appending content using jQuery is not the same as working with strings. It creates separate elements that are siblings, rather than building one continuous string of HTML. Also, remember that each element must have a unique ID.

 $('#div1').append(
    '<div id="target">' +
    '<p> Title: ' + jd["items"][i]["title"]    + '</p>' +
    '<p> Description: ' + jd["items"][i]["description"]   + '</p>' +
    '<p><img alt="" src=/uploads/' + jd["items"][i]["image1"] + '></p>' +
    '</div>');

Answer №2

It seems like your $.getJSON() request did not successfully retrieve any data, resulting in the absence of a div element with the id "target".

The error message generated by the $.getJSON() call indicates: "No 'Access-Control-Allow-Origin' header is included in the requested resource. The origin 'null' is consequently restricted from accessing it. Additionally, the response received was accompanied by an HTTP status code 404."

Answer №3

Experiment with

window.onload = function() { 

as an alternative to

$(document).ready(function() {

You might want to consider relocating this

$("#hide").click(function(event){
  var ele = document.getElementById("target");
  ele.style.display = "none";                   
});

after

$("#driver").click(function(event){
.
