Use IFrame in LWC Salesforce

by Rijwan Mohmmed

Hello friends, today we will discuss Use IFrame in LWC component in Salesforce. We use an iframe to load other website pages. Like if you want to show third-party page eg. then you just need to put this URL link in iframe src. We can give height and width in the iframe. We also use event listeners like onload for the call LWC js method.

Also check this: Test Data Factory in Apex Salesforce

Key Highlights :

  1. We use the iframe to display visualforce page where we can send parameters in URL and the page load accordingly.
  2. We also use iframe for generating pdf.
  3. Load third-party web page
  4. we need to put a third-party URL in CSP security so the page can load in Salesforce.

Code :

First, we will store our website link in CSP Trusted Sites.

Hello Rijwan,
I have created the above LWC component and added it to the experience cloud, but I passed the Google form in the URL. LWC component shows Google form with an error – “JavaScript isn’t enabled in your browser, so this file can’t be opened. Enable and reload.” I am unable to fill the form. I have also enabled JavaScript in the Chrome browser but the same error is showing, Can you help me to resolve this issue?

Hi @Yash, Can you book a meeting so I can resolve your issue

You actually make it seem so easy with your presentation but I find
this topic to be really something that I think I would never understand.

It seems too complex and very broad for me.
I am looking forward for your next post, I’ll try to get
the hang of it!
