Currently, I have a scenario where there are two select boxes. The selection in one box acts as a filter for the other box. In some cases, this filter results in only one option left in the list. I am exploring options to automatically select that lone option if it is the only one available.
If my explanation is unclear, I can provide an example for better understanding.
Your assistance is greatly appreciated.
While this question doesn't pertain to Angular, I can provide a solution using jQuery:
var totalItems=$('#myselect').children('option').length;
if(totalItems == 1) {
$("#myselect option:first").attr('selected','selected'); // selecting the first option
}
If you are aware of the value, you can select based on it: $('[name=myselect]').val( 3 ); // Choosing a value of 3
You can also choose based on text.
