How to Reload the Content of a Div with jQuery and Ajax on Button Click?

Reload Div Content with jQuery and Ajax

Problem:

You need to reload the content of a specific div on the click of a button without refreshing the entire page.

Code Sample:

<code class="html"><div role="button" class="marginTop50 marginBottom">
  <input type="button" id="getCameraSerialNumbers" value="Capture Again" class="disabled" />
  <input type="button" id="confirmNext" value="Confirm & Proceed" class="disabled marginLeft50" />
</div>

<div id="list">
  <!-- Content to be reloaded -->
</div></code>

Incorrect Approach:

<code class="javascript">$("#getCameraSerialNumbers").click(function () {
  $("#step1Content").load();
});</code>

This code is incorrect because the load() method needs a URL to load content from.

Solutions:

jQuery's load() method can be used with a URL to load remote content. However, to reload content from the current page, we can use the following approach:

1. Use Absolute URL with Hash:

<code class="javascript">$("#list").load(location.href + " #list");</code>

This loads the content of the element with the ID "list" from the current URL. Note the space before the second "#" sign.

2. Use Ajax:

Another approach is to use Ajax. With this approach, we make an Ajax request to the server, retrieve the content, and update the div.

<code class="javascript">$("#getCameraSerialNumbers").click(function () {
  $.ajax({
    url: "YOUR_ENDPOINT_URL",
    success: function (data) {
      $("#list").html(data);
    },
  });
});</code>

In this case, the "YOUR_ENDPOINT_URL" is the server endpoint that returns the content to be loaded into the div.

Additional Notes:

1. Make sure that the "Capture Again" button is enabled before reloading the content.
2. If you are using the Ajax approach, ensure that the server endpoint returns the content in the appropriate format (HTML or JSON).
