Tips for removing a class with ng-class when a value is empty or evaluates to nothing

I'm facing an issue with a class I've created called .lines-hover. My goal is to remove this class when the values in the td elements are empty.

For reference, take a look at this example:

If you observe closely, on some of the lines, such as Money Line, when it's empty, the .lines-hover class changes to false. I want to achieve this using ng-class, but being new to Angular, I found the examples in their documentation a bit confusing.

HTML:

<td class="lines-hover">
 <a href="javascript:void(0);" >
  <span ng-hide="row.noTotal">
   {{:: row.total.type}}{{:: row.total.spread}}({{:: row.total.moneyLine}})
  </span>
 </a>
</td>

CSS:

.lines-hover:hover {
  background: #3B3F45;
  a {
   color: #fff;
   text-decoration: none;
 }
}

Answer №1

If you want to apply styling based on the truthiness of row.noTotal, then you can utilize the ngClass directive in Angular:

<td ng-class="{'lines-hover': !row.noTotal}">
    <a href="javascript:void(0);">
        <span ng-hide="row.noTotal">
            {{:: row.total.type}}{{:: row.total.spread}}({{:: row.total.moneyLine}})
        </span>
    </a>
</td>
