JavaScript - The function will not execute any code inside its body

When I try to call my constructor function, it stops at the function definition in the debugger and never reaches the actual function body. Is there a common reason for this issue that I might be missing? Here is an example of the code:

myconstructor.js

function MyConstructor(optionalParam) { //this breakpoint gets hit
    var newobj = {}; //breakpoint never hit
    //code to check for null parameter
    //other code
};

main.js

var myConstructor = new MyConstructor();

I feel like I must be overlooking something obvious, but I can't seem to figure out what it is. Both Firefox/Firebug and Visual Studio do not show any errors or warnings.

Any help would be greatly appreciated!

Answer №1

It seems like your syntax is on point, and it's functioning within the text. Have you double-checked to ensure all script tags are properly closed?

<script src="myconstructor.js" type="text/javascript">

<script type="text/javascript">
  var myConstructor = new MyConstructor();
</script>

Unfortunately, this approach will not produce the desired outcome. If this isn't the issue, then I am unsure what else could be causing the problem.
