Sending HTML content to a personalized directive

Question

Sending HTML content to a personalized directive

I am a beginner in Angular and I am attempting to streamline the process of creating tables with CRUD functionality for work.

For instance:

Here is an example declaration:

<custom-table datasource="persons" headers="headers">
        <custom-column header="header1" display-member=""/>
        <custom-column header="header2" display-member=""/>
</custom-table>

In this case, my custom-table directive returns a table element. The issue I am facing is that I need to access ALL columns to properly create both the header and body of the table, but I am unsure how to retrieve the columns passed as content within the directive... (I am aiming to minimize the use of jQuery as much as possible)

So far, I have only been able to read each column individually, but this approach does not allow me to construct the table correctly. My goal is to gather all column declarations, generate the table header, and utilize ng-repeat for the body.

If you're trying to access the content of your directive (such as column definitions), there are a few ways to do it. However, it's important to note that this involves more advanced usage of Angular and may not be the best approach:

1 - You can use the transclude function to compile the inner HTML. Within your directive's link function, you can receive the transcludeFn as the 5th argument. This allows you to compile the contents within your directive and use them as needed.

2 - Another option is to implement the compile function within your directive. This function will receive the HTML and you can query it to extract the inner HTML.

Instead of trying to retrieve the directive content, consider turning your table columns into directives themselves.

For inspiration on how to handle parent-child component relationships, take a look at how the angular-UI/bootstrap project implemented their tabs component and how they communicate with each other.

Instead of creating directives for this purpose, why not consider dynamically building the table when needed? Check out this codepen for an example.

<table>
  <thead>
    <tr>
      <th ng-repeat="value in table.data.headers">{{value}}</th>
    </tr>
  </thead>
  <tbody>
    <tr ng-repeat="item in table.data.body">
      <td ng-repeat="property in item">{{property}}</td>
    </tr>
  </tbody>
</table>
