Coldfusion glassfish3/6/2023 The tag needs to be closed with the tag in order to tell the ColdFusion Server where to restart the loop. That variable is then output on the page each time the loop processes. These attributes tell the cfloop tag to loop over a section of code 10 times, and to place the current number of the loop in a variable called "my_index". In this case, the tag has been passed three attributes, for "index", "from", and "to". That is to say that additional parameters can be passed to a tag by adding attributes to it as a series of key/value pairs. Understood HTML and how tags worked, you could easily pick up the concept of ColdFusion tags and how they extended HTML with dynamic functionality.ĬFML tags, like HTML tags, have attributes. The original tag-based approach made ColdFusion an easy language to learn. A list of all of the CFML tags can be found at ColdFusion tags, much like HTML tags, are opened with an open angle (less than sign) and are closed with an end angle (greater than sign). In the beginning, ColdFusion borrowed this tag based approach to create CFML, the ColdFusion markup language. For example, is a start tag, is the closing tagĪnd so, HTML, in its most basic form, consists of tags, possibly with attributes, and possibly needing to be closed. An end tag is an html tag with a backslash before the name. Some tags need to be closed, with the use of an end tag. Some tags have attributes, such as the "charset" attribute of the tag in the example above. They have a tag name at the beginning such as body or title. Īs you can see, tags start an open angle (less than sign) and end with an end angle (greater than sign). Let’s look at the code for a very basic HTML5 document. Even the most modern version of HTML, HTML5 uses tags as it’s primary means of creating an HTML document. HTML’s primary construct to build web pages are called tags. Documents have a head, body, and footer, with portions of text and sections that are defined and organized. HTML by definition is a markup language that creates well structured documents. CSS was a fraction of what it is now and web-based scripting languages like Javascript were in their infancy. When ColdFusion was originally released by Allaire Corporation over 25 years ago, the web was not the dynamic experience it is today. Tags: One of the building blocks of CFML ColdFusion Tags Consult documentation for the version of ColdFusion you are coding against for compatibility. As such, please understand that there may be some limitations in older versions.As of the time of this writing, I will assume that new developers and new development will be utilizing ColdFusion 2021 or ColdFusion 2018. You are using a modern version of ColdFusion.You have little to no knowledge or experience building web based applications.AssumptionsĪrticles written in this series will assume a few things: This series is intended to help with that and provide a resource to developers who are just getting started with ColdFusion. We all started programming somewhere, and I believe there is a dearth of “basic training” available for ColdFusion newcomers. I don’t believe that ColdFusion is a dead or dying language, but I believe that bringing new developers into the fold starts with the basics. I’ve struggled with the reputation ColdFusion has, and I’ve watched the customer and developer base dwindle. I’ve been developing websites, applications, and software using ColdFusion for over 20 years.
