JScript vs VBScript

Hi all I've been using TestComplete for a few years now and have been writing scripted tests in VBScript and have to say that I've never encountered any problems with doing so (at least no issu...

    Hi Stephen,



    This is interesting... I never ran into your issue because all our application (VS C++) elements that respond to wText return a String.



    With the following test code:



    function someString() {

      this.type = "someString";

    }


    someString.prototype.getString = function (){

        return new Object("aString for class " + this.type);

      }



    function TestStringVar()

    {

      var aStringObject = new someString();

      var anObject = new Object("someOtherString");

     

      Log.Message(aStringObject.getString()); 

      Log.Message(aStringObject.getString().toLowerCase()); 

      Log.Message(aStringObject.toString());

     

      // This raises the exception that triggered this thread

      //Log.Message(aStringObject.toLowerCase());

      

      Log.Message(anObject.toLowerCase()); 

      Log.Message(anObject.toString());

      Log.Message(anObject);

     

    }



    And with your code, I can reasonnably assume that if textBox.wText.toLowerCase() doesn't work, textBox.wText.toString().toLowerCase() will.



    Sincerely

Couple of points to make here:



I've been writing Javascript for 15 years or so and I can probably count the number of times I've genuinely needed to use new String(), new Array(), new Object(), etc on the fingers of one hand. 



new String() isn't used to initialise a string value, it's to create an object which inherits from the String prototype, to which you can attach new properties and methods.





Another thing is that the .toString() method of your text object may be a method of that object in its original development language, not the similarly name javascript method.



For instance, in a Java SWT application there may be fields that contain Java strings, which appear to have text values but javascript can only interpret the object's OleValue property as a string. The Object Browser is your friend here.





Lastly, if you like the terseness of LCase, simply declare a function to do the equivalent, rather than writing out the conversion long-hand every time.
