Question

How can i determine first row of html table using angular?

I can think of a few hacky ways, but for example below in my doSomething method, how can i determine the rowIndex?

        <tr ng-repeat="a in mydata">
            <td><b>{{doSomething(mydata.name)}}</b></td>
            <td>{{age}}</td>
            <td>hello</td>
        </tr>

html
angularjs

Answer 1

ng-repeat provides properties $first, $index, $middle, and $last. Since in the title question you asked about the first row, you could pass $first as a boolean:

<tr ng-repeat="a in mydata">
    <td><b>{{doSomething($first)}}</b></td>
    <td>{{a.age}}</td>
    <td>hello</td>
</tr>

Answer 2

AngularJS automatically includes the magic $index in an ng-repeat. So you can get the row number like so:

<tr ng-repeat="a in mydata">
  <td><b>{{doSomething($index)}}</b></td>
  <td>{{a.name}}</td>
  <td>{{a.age}}</td>
</tr>
