Setting existing value as default in Select dropdown - angularjs

Question

I have a drop down which contains the following values
<select class="form-control">
<option value="critical">Critical</option>
<option value="high">High</option>
<option value="medium">Medium</option>
<option value="low">Low</option>
</select>
Because of this in drop-down the value is always selected to "Critical"
In my scope i have defined the values of severity per drop-down. How do i select that ?
For example say the value is "High". How do i set the default value to high and not critical

Answer 1

You'll need to define at object within your scope and bind it to the ng-model of your select.
Script
$scope.form = {
"severity": "high"
};
HTML
<select class="form-control" ng-model="form.severity">
<option value="critical">Critical</option>
<option value="high">High</option>
<option value="medium">Medium</option>
<option value="low">Low</option>
</select>

Answer 2

There are a couple of ways to select an option with angular:
1- Bind it to a model and set the model:
<select class="form-control" ng-model="myValue">
And
$scope.myValue = 'medium';
2- You can set it in a directive by jQuery or JS:
$("#yourselectid").val('low');
