The Ultimate Guide To Iframe Tag In Salesforce

Sharing is caring!

Tags in Salesforce are words or short phrases that you can align with your Salesforce records to describe and organize your Salesforce data in a personalized way. You can utilize Salesforce tags to group records from various objects by a standard topic or usage, and then use those tags to search and gather information quickly.

Introduction To VisualForce Tags

VisualForce tags provide developers a more powerful way to build high-quality applications and customize the Salesforce user interface. VisualForce comprises a collection of XML markup tags. These tags are also known as Components. 

Like VisualForce, there are many other development languages like JSP, ASP.NET that consist of tags, serving as a container to the structure data returned by the controller. And the class is written in Apex. VisualForce tags are easy to use when compared with .net. 

Advantages of VisualForce

  1. VisualForce follows the Model View Controller (MVC) development style.
  2. VisualForce editor Panel is available at the bottom of the page for each VisualForce page.
  3. VisualForce consists of a large number of built-in components.
  4. VisualForce can also be integrated with HTML, CSS, Ajax, jQuery.

Types of VisualForce tags

A single VisualForce page is required to be wrapped inside a single page component tag. This component supports HTML pass-through attributes using the “HTML-” prefix. 

Pass-through attributes are attached to the generated <html> tag.

VisualForce Tags are divided into the following categories:

  • Input tags.
  • Output tags.
  • Select tags.
  • Form tags.
  • Page tags.
  • Action tags.
  • Style tags.

What is the Iframe Tag in Salesforce?

 The Iframe is the tag that can be used to display another document using the current HTML document.

                      title=”W3Schools Free Online Web Tutorials”>

         </iframe>
