Question

Here are the steps to pass the selected dropdown value to ng-repeat for ordering:

I have a dropdown box with options for filtering data in an ng-repeat by different criteria. How can I pass the selected value from the dropdown to the ng-repeat orderby?

Here is my dropdown:

<select name='filter_range' id='filter_range' onchange='filter()'>
    <option value='mrplow'> MRP Low To High</option>
    <option value='mrphigh'> MRP High To Low </option>
    <option value='qtyhigh'> Qty Low To High </option>
    <option value='qtylow'> Qty High To Low </option>
</select>

Using AngularJS:

<div ng-app="myApp" ng-controller="MyController"> 
    <div ng-repeat="grp_val in sample | orderBy:selectedValue">
        <label>{{grp_val.product}}</label><br>
    </div>
</div>

How can I dynamically set the orderBy value to the one selected in the dropdown?

Let me demonstrate an example that closely resembles your issue:

    const fruits = ['apple', 'banana', 'cherry'];
    console.log(fruits.sort()); // Output: ["apple", "banana", "cherry"]

<script src="https://cdn.jsdelivr.net/npm/vue@2.6.14/dist/vue.min.js"></script>
<div id="app">
  <p>Original Array: {{fruits}}</p>
  <p>Sorted Array: {{sortedFruits}}</p>
</div>

<script>
new Vue({
  el: '#app',
  data: {
    fruits: ['apple', 'cherry', 'banana']
  },
  computed: {
    sortedFruits() {
      return this.fruits.sort();
    }
  }
});
</script>

If the data you are working with contains properties like "mrp" and "qty", this solution should help resolve your issue:

<select ng-model='orderProp' name='filter_range' id='filter_range'   onchange='filter()'>
    <option value='mrp'> MRP Low To High</option>
    <option value='-mrp'> MRP High To Low </option>
    <option value='qty'> Qty Low To High </option>
    <option value='-qty'> Qty High To Low </option>
</select>

<div ng-app="myApp" ng-controller="MyController"> 
    <div  ng-repeat = "grp_val in sample | orderBy: orderProp"
        <label>{{grp_val.product}}</label><br>
    </div>
</div>

Make sure to adjust the option values of your select box based on the properties of your "sample" object, then connect the select box value to "orderProp" which will be used in the ng-repeat directive with the orderBy filter.
