javascript iterator and generator

Question

I have written below code:

<script type="text/javascript">
function testGenerator()
{
yield "first";
document.write("step1");
yield "second";
document.write("step2");
yield "third";
 document.write("step3");
 }
 var g = testGenerator();
document.write(g.next());
document.write(g.next());
 </script>

My desired output: step1step2 But the above code show nothing on my html. Could any one help me to figure out what the mistake I have done here.

Thanks

yield is not supported in ES5. Generators will be available in ES6 (which probably takes a long time to be picked up by browsers...). — Felix Kling

Generators/iterators are currently only supported by Firefox, and to use them you need to change your script tag's type attribute to "text/javascript;version=1.7".
