Obtain various Angular.js controllers for multiple <td> elements within a single <tr> tag

I am attempting to include multiple angular controllers within the same tr tag. However, I am facing an issue with Chrome rewriting the table and not allowing any element between tr and td in the HTML hierarchy.

Currently, I have different colors representing different controllers to call. You can see the visual representation of my goal in the table image below: https://i.sstatic.net/MnfSD.png

While I could use a global controller or multiple div elements with fixed width, it is preferred to use a single tr table. Here is a snippet of the code:

<table>
    <tr>
        <div ng-controller="testController">
            <td>{{testcontrollerscopevalue}}</td> <!-- empty when displayed -->
            <td>{{testcontrollerscopevalue2}}</td> <!-- empty when displayed -->
            <td>{{testcontrollerscopevalue3}}</td> <!-- empty when displayed -->
        </div>
        <div ng-controller="testController2"> 
            <td>{{testcontroller2scopevalue}}</td> <!-- empty when displayed -->
        </div>
    </tr>
</table>

Below is a working example for reference:

 <table ng-controller="testController">
        <tr>
            <td>{{testcontrollerscopevalue}}</td> <!-- set when displayed-->
        </tr>
    </table>

In the generated HTML by Chrome:

<body>
<div ng-controller="testController"></div>
<div ng-controller="testController2"></div>
<table>
    <tbody>
    <tr>
        <td>{{testcontrollerscopevalue}}</td> <!-- out of scope-->
        <td>{{testcontrollerscopevalue2}}</td> <!-- out of scope-->
        <td>{{testcontrollerscopevalue3}}</td> <!-- out of scope-->
        <td>{{testcontroller2scopevalue1}}</td> <!-- out of scope-->
    </tr>
    </tbody>
</table>

 <table ng-controller="testController">
        <tbody>
        <tr>
            <td>{{testcontrollerscopevalue}}</td> <!-- set -->
        </tr>
        </tbody>
    </table>

If there is a way to achieve this using a different tag instead of div, or if you have any suggestions, I would greatly appreciate your help. Thank you!

Answer №1

After an in-depth discussion in the online conversation, it became clear that utilizing the ControllerAs Syntax and nesting the <table> element within multiple <div> elements, each containing specific controller logic, would be most beneficial in this scenario.

I proposed a solution similar to the following code snippet:

<div ng-controller="testController as tc">
  <div ng-controller="testController2 as tc2">
    <table>
      <tbody>
        <tr>
          <td>{{tc1.testcontrollervalue}}</td>
          <td>{{tc1.testcontrollervalue2}}</td>
          <td>{{tc1.testcontrollervalue3}}</td>
          <td>{{tc2.testcontroller2value1}}</td>
        </tr>
      </tbody>
    </table>
  </div>
</div>

In order for this approach to be effective, it is crucial that your variables are transformed into properties of the controller rather than properties of $scope.

var tc1 = this; //consistent reference to controller object
SomeService.get(function(data) {
  tc1.someProperty = data;
});

Answer №2

To achieve this, simply use the following code:

<td ng-controller="testController2">{{testcontrollerscopevalue}}</td>

In case you insist on including a div:

<td><div ng-controller="testController2">{{testcontrollerscopevalue}}</div></td>
