Future plans for SA5 dynamic attributes

Smart options

• Force overwrite

• Overwrite only if non-blank ( coalesce )

Change to x: prefix

Currently we prefix attributes with x- however this convention is already used in Alpine JS. While this is unlikely to create conflicts, we'd like to avoid the possibility of confusion as well.

Binding to SA5 Simple Data Sources

x:attr:bind = ?query

? Use cases ??

Transformer Functions

Combine information from several sources and set it as a dynamic attribute value.

• Other attributes on this element

• Other attributes on other elements

• Static text

x:attr:transform = {{#abc}}def{{#ghi}}

This technique can also be adjusted to the target the parent element's attribute or immediate siblings.

Target Element	Attribute	InnerText	InnerHTML
	Here attr is an example attribute name we want to reference.
Current element attribute	{x:myval=#attr}}
Parent element attribute	{{^#attr}}
Prev sibling element attribute	{{<#attr}}
Next sibling element attribute	{{>#attr}}
Current element innerText
Specific named element	{{name.#attr}}	{{name.$}}	{{name.%}}

Examples

<div abc="123" ghi="456">789</div>

	Interpreted As	Resulting Value
12{{#abc}}	String "12" Attribute abc value	12123
{{#abc}}def{{#ghi}}	Attribute abc value String def Attribute ghi value	123def456

Removing Attributes After processing

Default false, but can enable this as a lib config option.

Prefix and Postfix

x:(attr):pre = ( value )

x:(attr):post = ( value )

Future;

x:(attr):format = ( value )

<img 
  x:src="image.jpg" 
  
  
  x:src:pre="https://cdn.example.com/" 
  x:src:post="?version=123">
  
  
  
  x:src:start
  x:src:end
  
  x:src:before
  x:src:after
  
  
  
  

Would result in;

<img src="https://cdn.example.com/img.jpg?version=123"> 

<img 
    src="image.jpg" 
    x:src:pre="https://cdn.example.com/" 
    x:src:post="?version=123"  
/>

Future;

<img 
    src="image.jpg" 
    x:src:pre="https://cdn.example.com/" 
    x:src:post="?version=123" 
    x:src:format="{x:pre:src}{src}{x:post:src}" 
    x:src:transform="funcName" 
/>

Calls a JS function on window.funcName, and passes the element. The function returns a value, which is then applied to the attribute.

Use cases;

• In a CMS-bound link, append #hash or ?query=foo data.

• Append classes to your class list without overwriting them

<div class="foo" x:post:class="bar"></div>

Result;

<div class="foo bar"></div>

Use cases;

<script> based transforms

Generate an attribute from a specially-typed script block within it, with the purpose being to;

• Easily mix static text and dynamic attributes

• Support larger strings, e.g. JSON chunks

• Resolve attribute content limitations in Webflow

  • Inability to include double-quotes " in content

• Resolve attribute name limitations in Webflow

Targeting can be parent, prev sibling or next sibling, or a target element(?) with an SA5 identifier

Supporting JSON chunks in the designer

" /x0022

Ideally design this so that it can also support Hyperflow processing.

Transforms

Learn more

Dynamic Attributes are likely to become a facet of a larger SA5 concept we'll call DOM Transforms. Transforms allow for broad changes to happen, and have a specific instructional paradigm;

• What to target, relative to the transform's position- useful for collection lists.

• What kind of transformation to do.

• The data needed for the transformation

For example

sa5:transform:attr

• Targeting

  • target

  • selector

  • attr

• Transform

  • transform = append | replace | prepend, etc

• Data

  • val = (value)

    • Typically a field embed. This would be HTML encoded

  • decode = html | none

  • encode

We're looking at adding

// Some code
<script type="sa5:transform:attr"
   target="closest"
   selector="'a'"
   transform="append"
   attr="href"   
   val="{{wf {&quot;path&quot;:&quot;name&quot;,&quot;type&quot;:&quot;PlainText&quot;\} }}"
   encode="querystring" 
   ></script>

// Some code
<script type="sa5:transform:attr"
   target="closest"
   selector="'a'"
   transform="append"
   attr="href"   
   val="{{wf {&quot;path&quot;:&quot;name&quot;,&quot;type&quot;:&quot;PlainText&quot;\} }}"
   encode="querystring" 
   ></script>
