![]() ![]() ![]() I’d like to make the iframe auto-adjust so that it stays at 80% of the visual viewport, even if the participant tries to resize the page, but I’ll figure that out later.Ĭan anyone help me figure out where I need to adjust my code so that the video is at about 80% of the viewport? I’m troubleshooting using the “troubleshoot” routine. Window.My experiment calls youtube.html using the following routine code if ((showVideo != undefined)) ) (we do this on load because then all images have loaded.) IframeDimensions_Old = iframeDimensions_New If( (iframeDimensions_New.width != iframeDimensions_Old.width) || (iframeDimensions_New.height != iframeDimensions_Old.height) ) // if old width is not equal new width, or old height is not equal new height, then. 'width': window.innerWidth, //supported from IE9 onwards send the latest page dimensions to the parent page on which this iframe is embedded Create your own server using Python, PHP, React.js, Node.js, Java, C, etc. Host your own website, and share it to the world with W3Schools Spaces.

When change is detected, it sends send the latest size to the parent page using postMessage This code monitors the page for changes in size. Add this script into the page that will appear inside an iFrame Var matches = document.querySelectorAll('iframe') // iterate through all iFrames on pageĬopy this second script into the of the page that will be contained in the iFrame: In our system, we use the default template called Standard. Go to the template you use most often to render your forms. ![]() event.source - a reference to the 'window' object that sent the messageĬonsole.log( "got resize message: " + JSON.stringify(event.data)) This will let you alter the code that appears with every Pardot form that will be contained inside an iFrame. event.origin - the URL from which the message came event.data - the object that the iframe sent us This code resizes the iFrame's height in response to a postMessage from the child iFrame Add this script to the parent page on which your iFrame is embedded OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, IN NO EVENT SHALL THEĪUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,įITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

It monitors the iFrame for changes in height, and then uses the Window.postMessage() mechanism to instruct the parent page to resize the iFrame. I have prepared some JavaScript code that solves the problem. That post contains some great sample code for making your forms look good. Note: The animation of the Pardot form above is using a form from a post by Alex Avendano at EBQ, on customizing the design of Pardot forms. What we want is for the form’s iFrame to grow vertically so that all the content shows up. This GIF shows an iFrame bar appear after the embedded form’s content gets taller Note what happens when the form is submitted with missing information: several error messages appear and add a distracting scrollbar at the right side. When that happens, an unattractive scrollbar gets added next to the content – and the content no longer looks like it is a natural part of the parent webpage.īelow is an example of a Pardot marketing form that’s been embedded using an iFrame. Also, their height can change unexpectedly. The problem with iFrames is that you don’t always know their full height. Normally, I would put code like this onto the page so the form appears in an iFrame: The problemĪs a Marketing Operations professional, I often need to put marketing forms onto webpages. The code works for cross-domain iFrames and does not use any libraries like jQuery. iFrame height will adjust based on the height of the content in them. This page contains freely-usable code for responsive iFrames. Do you need to ensure your iframe’s height is always set to 100% of the height of the content you are embedding? If so, keep on reading. ![]()
