`Considering various factors to alter class pairings`

I have defined a few style classes in my stylesheet as shown below:

.left-align{
  /* some styles here */
}
.right-align{
  /* some styles here */
}
.validate-error{
  /* some styles here */
}

Depending on the type of data, I need to align the content either left or right. Additionally, I want to validate the data in the control and if validation fails, I need to append the validate-error class to the ng-class. I have researched various Stack Overflow threads, articles, and QA sites discussing multiple conditions in ng-class, but so far nothing has worked for my specific scenario. I have attempted the following based on the references:

ng-class="{!vm.validate()?'validate-error': vm.isNumericField?'right-align':'left-align'}"

However, this approach does not align the content to the right even when isNumericField is true if validate() returns false.

In summary, I need to apply the left-align or right-align class depending on the value of the isNumericField property, and include the validate-error class if validate() returns false.

"isNumericField?{'left-align':'right-align'} + 'validate-error':validate()"

If anyone knows of a way to achieve this, please let me know:

Answer №1

If you want to define a "map" using class names and boolean values, use the following syntax:

ng-class="{'validate-error': !vm.validate(), 'right-align': vm.isNumericField, 'left-align': !vm.isNumericField}"
