Question

I want to call a parent window JavaScript function from an iframe.

<script>
    function abc()
    {
        alert("sss");
    }
</script>

<iframe id="myFrame">
    <a onclick="abc();" href="#">Call Me</a>
</iframe>

Answer 1

<a onclick="parent.abc();" href="#" >Call Me </a>

See window.parent

Returns a reference to the parent of the current window or subframe.

If a window does not have a parent, its parent property is a reference to itself.

When a window is loaded in an <iframe>, <object>, or <frame>, its parent is the window with the element embedding the window.
