<title>Anchor element with onclick form submission and href to fragment</title>
<script src="/resources/testharness.js"></script>
<script src="/resources/testharnessreport.js"></script>
<!-- When an anchor element has an onclick handler which submits a form,
the anchor's navigation should occur instead of the form's navigation.
However, if the anchor has an href which is just a fragment like "#",
then the form should be submitted. Many sites rely on this behavior. -->
<iframe name="test"></iframe>
<form target="test" action="resources/form.html"></form>
<a id="anchor" target="test" onclick="document.forms[0].submit()">Test</a>
<script>
async_test(t => {
const iframe = document.querySelector('iframe');
iframe.onload = t.step_func(() => {
const anchor = document.getElementById('anchor');
anchor.href = '/#';
anchor.click();
window.onmessage = t.step_func(event => {
if (typeof event.data === 'string' && event.data.includes('navigation')) {
assert_equals(event.data, 'form navigation');
t.done();
