"Using ng-click to access values from other elements in AngularJS

Can someone help me retrieve the value of an input field when a button is clicked?

Here is my controller code:

app.controller('MainCtrl', function($scope) {
  $scope.test = function(val) {
    alert(val);
  }
});

This is my HTML snippet:

<body ng-controller="MainCtrl">
    <input type="text" id="inputText">
    <button type="button" ng-click="test(document.getElementById('inputText').value)">Test</button>
</body>

When I click the button, 'undefined' appears in the alert. Can anyone guide me on how to make this work in Angular?

Answer №1

Utilizing ng-model on the specified input

<input type="text" id="inputText" ng-model="myInput">
<button type="button" ng-click="test(myInput)">Test</button>

Answer №2

When you rearrange the elements in this way

<input type="text" id="inputText" ng-model="myInput">

<button type="button" ng-click="test(myInput)">Test<//button>

You may find that you are unable to retrieve the value of myInput. This situation can appear confusing! One possible reason for this issue is if your button is placed within a div container.
