如何启动PARENT jQuery函数？

Question

I'm trying to figure out how to launch a function from an iframe but the following example won't work, any ideas?

<input class='reply' onclick='parent.replytopost()' type='button' value='Reply' />

PARENT PAGE FUNCTION (In the body if that makes a difference):

<script>
  function replytopost(){
  alert("test");
  parent.document.getElementById('mainbar').innerHTML = "TEST";
  parent.document.getElementById('post_reply').show();
  }
</script>

Answer 1

This might become an issue with security-tightened browsers (such as Safari).

I ran against the same type of problem recently, and I'm now a happy user of window.postMessage .

You will still have to reference it using window.parent but this will prevent the vast majority of issues to happen.

Answer 2

Will window.opener work for you? I know it works from a parent to a newWindow. I don't know about iframe.

It works for me. Look here

Why do you call parent.* in non-iframe replytopost script?
