Create new Object From Variable in JavaScript

 / Published in: JavaScript


This example of code allows you to create a new object in javascript (using simple inheritance) such that the class of the object is defined from a variable. After creating the object you may use it for your purposes.

  1. <script type="text/javascript">
  2. var className = "PluginClass";
  3. // get a reference to the class object itself
  4. // (we've assumed the class is defined in a global scope)
  5. var myclass = window[className];
  6. // now you have a reference to the object, the new keyword will work:
  7. var inst = new myclass();
  8. // now call to the required method of your class
  9. // alert(inst.validate("4111111111111111", "visa"));
  10. </script>
