This OLCC programming example page demonstrates getting a list of isomers from PubChem using JavaScript.
It does this by starting a search and polling the server every second until it is complete. But see also how to avoid polling using PubChem "fast" methods.

Press the "test" button to evaluate the JavaScript in the textarea below.
Feel free to modify the JavaScript and press test again.
