I am looking to adjust the width of an element within an Iframe

In my single post, I have a social sidebar on the left side. Currently, the buttons in the sidebar are appearing in different sizes, but I want them all to be the same size as the "Twitter" button. To see the issue, please visit this link.

I've tried various code solutions, but none seem to work because the source is an iframe. Specifically for Google+, I attempted the following code:

$('#___plusone_1 iframe').load(function(){
  $('#___plusone_1 iframe').contents().addClass('googleplusbtn');
 }

Could someone please provide assistance with this? Thank you.

I have also looked at these tutorials, but unfortunately, they did not work for me:

Answer №1

It doesn't seem possible to achieve this because your main page () and the iframes () belong to different domains.

The Jquery Contents function is explained as:

The .contents() method can retrieve the content document of an iframe, but only if the iframe is on the same domain as the main page.

Reference: JQuery .contents()

Answer №2

If the iframe URLs are from the same domain, you can implement the following solution:

Using jQuery:

$("#iFrame").contents().find(".someButtons").addClass("googleplusbtn");

Answer №3

When an iframe contains a page from the same application domain, it becomes possible to manipulate its content using the following script:

var iframeElement = document.getElementById('iframe1');
var innerDocument = iframeElement.contentDocument || iframeElement.contentWindow.document;

Once you have access to the inner document, you can modify elements like this:

innerDocument.getElementById('elementId').style.height="200px";

If you need to adjust the width of an iFrame using jQuery, this solution functions similarly to an iFrame. By utilizing a PHP script, you can retrieve content from another website and easily implement your own custom jQuery modifications. Take a look at the provided script below which retrieves external content and allows for the application of custom jQuery or JavaScript. This versatile content can be embedded within any element or page.

<div id='myframe'>

  <?php 
   /* 
    Utilize the function below to display the final HTML within this div
   */

   //Display Frame
   echo displayFrame(); 
  ?>

</div>

<?php

/* 
  Function to display frame from another domain 
*/

function displayFrame()
{
  $webUrl = 'http://[external-web-domain.com]/';

  //Fetch HTML from the specified URL
  $content = file_get_contents($webUrl);

  //Inject custom JS into the returned HTML content
  $customJS = "
  <script>

      /* Here I am writing a sample jQuery to hide the navigation menu
         You can write your own jQuery for this content
      */
    //Hide Navigation bar
    jQuery(\".navbar.navbar-default\").hide();

  </script>";

  //Combine Custom JS with HTML
  $html = $content . $customJS;

  //Return modified HTML
  return $html;
}

If you're looking to adjust the width with ease, jQuery can help you out. This method functions similarly to an iFrame. I've developed a PHP script that pulls content from another website, allowing you to seamlessly apply your own jQuery modifications. Take a look at the script below for extracting external content and integrating your custom JavaScript. This versatile content can be embedded anywhere within your site.

<div id='myframe'>

  <?php 
   /* 
    Utilize this function to showcase the final HTML within this div
   */

   //Show Frame
   echo displayFrame(); 
  ?>

</div>

<?php

/* 
  Function for displaying a frame from an external domain
*/

function displayFrame()
{
  $webUrl = 'http://[external-web-domain.com]/';

  //Fetch HTML from the provided URL
  $content = file_get_contents($webUrl);

  //Incorporate personalized JS into the retrieved HTML content
  $customJS = "
  <script>

      /* Here's a sample jQuery snippet to hide the navigation menu
         Feel free to write your own jQuery code for this specific content
      */
    //Hide Navigation bar
    jQuery(\".navbar.navbar-default\").hide();

  </script>";

  //Merge Custom JS with HTML
  $html = $content . $customJS;

  //Deliver tailored HTML output
  return $html;
}
