Solution for : Select default option value from typescript angular

Problem

if i have this code :

<select ng-model='nrSelect' class='form-control'>                                                                
    <option value='47'>47</option>
    <option value='46'>46</option>
    <option value='45'>45</option>
</select>

How can I select the default value from typescript for example 45 ?

Solution

You can do this :

<select  class='form-control' 
        (change)="ChangingValue($event)" [value]='46'>
  <option value='47'>47</option>
  <option value='46'>46</option>
  <option value='45'>45</option>
</select>
