Here is the structure of my HTML code:
<select class="form-control"
name="settings.provider"
id="settings.provider"
ng-model="settings.provider"
required>
<option value="" disabled selected>Select Provider</option>
<option value="thisProvider">thisProvider</option>
</select>
I am trying to programmatically select the option "thisProvider". How can I achieve this?
I attempted the following, but it did not work:
$scope.settings.provider = "thisProvider";
When your choices are not connected to an ng-repeat, you have the option to link each choice to a setting in the controller by utilizing ng-selected (https://docs.angularjs.org/api/ng/directive/ngSelected). Within the controller, you can create a boolean variable like $scope.thisProviderSelected for each choice and then set it to true for the choice you wish to be selected.
<select class="form-control" name="settings.provider" id="settings.provider"
ng-model="settings.provider" required>
<option value="" disabled selected>Select Provider</option>
<option value="thisProvider" ng-selected="thisProviderSelected">thisProvider</option>
</select>
An alternative approach would be to utilize ng-repeat and assign an isSelected property to each item in the list. This way, if the list is updated, any new items would automatically receive the appropriate selection status.
document.getElementById('settings.provider').value = 'thisProvider';<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<select class="form-control"
name="settings.provider"
id="settings.provider"
ng-model="settings.provider"
required>
<option value="" disabled>Select Provider</option>
<option value="thisProvider">thisProvider</option>
</select>Add Event Listener:
<a href="javascript:void(0);" onclick="selectItemByValue(document.getElementById('settings.provider'),2)">update</a>
Custom JavaScript Function:
function selectItemByValue(elmnt, value){
for(var i=0; i < elmnt.options.length; i++)
{
if(elmnt.options[i].value === value) {
elmnt.selectedIndex = i;
break;
}
}
}
Terminate the loop when the desired value is found.
var Person_ID = 2;
<a href="javascript:void(0);" onclick="document.getElementById('personlist').value=Person_ID;">update</a>
