JSON control if @currentfield is empty (2 answers)

PrimaryLink is to display a hyperlink based on the other 2 fields

PrimaryName
PrimaryURL
PrimaryLink

JSON for Column Formatting

{
   "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
   "elmType": "a",
   "txtContent": "[$PrimaryName]",
   "attributes": {
   "target": "_blank",
   "href": "[$PrimaryURL]"
    }
}

So if I enter a PrimaryName and a PrimaryURL, it would display the PrimaryName as a hyperlink in PrimaryLink to what was set in PrimaryURL. If I only put a PrimaryName in, it still displays a hyperlink that goes to the /list/AllItems.aspx

Is there a way where if I don't populate PrimaryURL, that it can only display PrimaryName text and no hyperlink?

Tried this from a post recommended in comments, but it leaves the whole column empty.

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
  "elmType": "a",
  "txtContent": "[$PrimaryName]",
  "attributes": {
    "target": "_blank",
    "href": "[$PrimaryURL]"
  }
    "style":{
        "display": "=if([$PrimaryURL]!='', 'block', 'none !important')"
    }
}

Use below JSON Code:

{
    "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
    "elmType": "div",
    "children": [
        {
            "elmType": "span",
            "txtContent": "[$PrimaryName]",
            "style": {
                "display": "=if([$PrimaryURL] != '', 'none', 'block')"
            }
        },
        {
            "elmType": "a",
            "txtContent": "[$PrimaryName]",
            "attributes": {
                "target": "_blank",
                "href": "[$PrimaryURL]"
            },
            "style": {
                "display": "=if([$PrimaryURL] != '', 'block', 'none')"
            }
        }
    ]
}

official documentation:

1. Use column formatting to customize SharePoint
2. Column formatting - Samples

Update from Comments:

1. In order to reference a column in JSON formatting it should be included in list view.
2. If you are adding the URL in PrimaryLink column and then adding the JSON in PrimaryName column then try below JSON:

{
    "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
    "elmType": "div",
    "children": [
        {
            "elmType": "span",
            "txtContent": "@currentField",
            "style": {
                "display": "=if([$PrimaryLink] != '', 'none', 'block')"
            }
        },
        {
            "elmType": "a",
            "txtContent": "@currentField",
            "attributes": {
                "target": "_blank",
                "href": "[$PrimaryLink]"
            },
            "style": {
                "display": "=if([$PrimaryLink] != '', 'block', 'none')"
            }
        }
    ]
}
