This is how my array is structured:
$scope.states = [{
"AB" : "Abia",
"AJ" : "Abuja",
"AN" : "Anambra"}];
Below is the HTML:
<select ng-options="state for state in states">
<option value=""></option>
</select>
Can someone guide me on how to correctly pass this data?
Your states is structured as an array containing a single object with state key/value pairs. Even though an object can be used with ng-options, it's unclear why an array is necessary. You can still reference the source object using "... in states[0]".
Additionally, ng-options mandates an ng-model to be included.
<select ng-model="selectedState"
ng-options="key as state for (key, state) in states[0]">
</select>
In the code snippet above, selectedState will be assigned the value of key (the abbreviation). It can also be assigned the value of state.
If the states array doesn't need to be a single-element array and instead directly represents the object, you can reference it as "...(key, state) in states" instead of ... in states[0]".
JavaScript:
const countries = {
"US" : "United States",
"CA" : "Canada",
"MX" : "Mexico"};
HTML:
<select ng-options="key as value for (key,value) in countries"></select>
