What is the Attributes property used for in a HtmlTargetElement attribute

Question

The way an attribute is set on an asp.net core tag helper is as follows:

[HtmlTargetElement("test1",Attributes = "make",ParentTag = "myparent")]

I'm not understanding the syntax Attributes = "make"

I know Attributes is a string that gets passed into the constructor of HtmlTargetElement but what I don't get is the = "make" part. If this were the call list of the method I now that would mean make is the value if null is passed in but I don't understand it when it's on the call method side.

What is the Attributes property used for in a HtmlTargetElement attribute?

Answer 1

The HtmlTargetElement attribute is used to specify additional criteria for a TagHelper to use when determining a match. The Attributes property specifies that an html element must contain that value to match. The attribute:

[HtmlTargetElement("test1",Attributes = "make")]``

Would match the following element:

<test1 make></test1>

Also keep in mind that you can decorate a class with multiple [HtmlTargetElement] attributes to result in a logical-OR.
