I'm getting familiar with PhantomJS. But I can't get one thing. I have a page with a simple form:
<FORM action="save.php" enctype="multipart/form-data" method="GET" onSubmit="return doSubmit();">
    <INPUT name="test_data" type="text">
    <INPUT name="Submit" type="submit" value="Submit">
</FORM>
and a save.php just writes down the test_data value
so I'm doing this:
page.evaluate(function() {
    document.forms[0].test_data.value="555";
    doSubmit();
});
When rendering the page I see that text field is 555, but form isn't submitting and save.php didn't write down a test_data value. So doSubmit() is not executing, is it? doSubmit() is a simple validation step and a submit is supposed to load the next page.
So the question is: how can I execute a javascript code on the page, using PhantomJS?
