similar: Inserting objects into global scope in classic ASP / Javascript

---

Trying to get started with using javascript in classic ASP. Seem to be some “gotchas” with this though: can anyone with some experience in this tell me what’s up with the “Blah2” code ? Seems like it “should” work but there seems to be a problem with my use of “this”…

<script language="javascript" runat="server">

 var Blah = {};
 Blah.w = function(s){Response.write(s);}

 Blah.w('hello'); //this works...


 var Blah2 = function(){
     this.w = function(s){Response.write(s);} 
     //line above gives 'Object doesn't support this property or method'
     return this;
 }();

 Blah2.w('hello');

</script>

Thanks for any pointers

Answer 1

You need parens around your function

var Blah2 = (function(){
    this.w = function(s){Response.write(s);} 
    //line above gives 'Object doesn't support this property or method'
    return this;
}());

Also, this.w isn’t doing what you want. this is actually pointing to the global object right there. You want:

var Blah2 = (function(){
    return {w : function(s){ Response.write(s); }};
}());

Or

bar Blah2 = new (function(){
   ...
