AngularJS: Get selected Text and Value of HTML Select DropDownList using ng-change
The below HTML Markup consists of an HTML DIV to which ng-app and ng-controller AngularJS directives have been assigned.
Note: If you want to learn more about these directives, please refer my article Introduction to AngularJS.
The HTML DIV consists of an HTML Select DropDownList which will be populated from JSON array using ng-options directive.
Note: If you want to learn more on how to populate HTML Select DropDownList using ng-options directive, please refer my article Populate HTML Select using ng-options.
The HTML Select DropDownList has been assigned ng-change directive. When an option is selected in HTML Select DropDownList then the GetValue function of the Controller gets called.
Inside the function, first the selected Value is fetched from the ng-model attribute and the selected Text is fetched from the JSON array using jQuery grep function.
Finally the selected Text and Value is displayed using JavaScript alert message box.
Note: If you want to learn more on displaying JavaScript alert with AngularJS, please refer my article AngularJS: Display (Show) JavaScript Alert box.
