Get selected value in dropdown list using JavaScript

If you have a select element that looks like this:
test1test2test3

Running this code:
var e = document.getElementById(“ddlViewBy”);
var strUser = e.value;

Would make strUser be 2. If what you actually want is test2, then do this:
var e = document.getElementById(“ddlViewBy”);
var strUser = e.options[e.selectedIndex].text;

Which would make strUser be test2

Plain JavaScript:
var e = document.getElementById(“elementId”);
var value = e.options[e.selectedIndex].value;
var text = e.options[e.selectedIndex].text;

jQuery:
$(“#elementId :selected”).text(); // The text content of the selected option
$(“#elementId :selected”).val(); // The value of the selected option

AngularJS: (http://jsfiddle.net/qk5wwyct):
// HTML

Text: {{selectItem.text}}

Value: {{selectItem.value}}

// JavaScript
$scope.items = [{
value: ‘item_1_id’,
text: ‘Item 1’
}, {
value: ‘item_2_id’,
text: ‘Item 2’
}];
