How to call a function in an iframe from the parent page?

Ho开发者_JAVA百科w to call a function in an iframe from the parent page?

---

As long as the framed page is on the same domain (or on a sub-domain, and you're setting document.domain), you need to access the contentWindow property of the frame element. For example:

$("#myFrame")[0].contentWindow.myFunction();

// or, if jQuery hasn't made you lazy 
document.getElementById("myFrame").contentWindow.myFunction();

Most browsers also support contentDocument, but Internet Explorer doesn't. If your framed page is on a different domain then you'll get an Access Denied error.

$("iframe").each(function()
{
    $(this).one("load", function()
    {
        $(this)[0].contentWindow.myFunction();
    });
});

It is necessary to loaded iframe ;)

Do it like a pro:

$("#myFrame").prop('contentWindow').abc();

---

did you try?

top.frames['my_frame'].myFunc();

---

You can select the iFrame using its id

document.getElementById(iframeId).contentDocument

but I am not sure you can access its JavaScript, especially if child iFrame is from different domain
