Executing a function in a parent frame

Copy linkTweet thisAlerts:
Aug 06.2006

Okay, so here’s the deal. I have an iFrame on my page and I want it to make the parent frame execute a function as if the parent frame was executing it. The problem is I can’t simply go parent.doIt(), because all that does is execute the doIt() function in the current iFrame. Any suggestions? I tried parent.eval(“doIt()”), but that didn’t seem to work either. I’ve considered creating events and then artificially firing them on the parent frame, but this sounds complicated as it’s different for IE and for Firefox, so I want to avoid that if possible.

TIA.

<a href="#" target="parent" onclcik="doIt()">

@nanodeathauthorAug 06.2006 — Well, two things with that. First, the doIt() function is actually in an external .js file (which [I]is[/I] linked by the parent frame), and secondly, I don't want this in a link, I just want it to be able to execute normally between two <script> tags.

@konithomimoAug 07.2006 — The link was simply an example, but in your case, you can either place the script directly into the parent frame page, or you can do:

parent.doIt();

@nanodeathauthorAug 08.2006 — So...does anyone have any other ideas for this? Like I said, calling parent.doIt() doesn't call doIt in the parent frame, but rather executes the doIt() function in the current frame...not what I want :-/

Embed it in the link where the target is the parent.

<a href="javascript:parent.doIt();" target="parent">

The doIt() function will be the one defined in the parent and any output from it will be directed to the parent.

If you are trying to do something weird like manipulate elements in the parent frame via your doIt function, then the only answere I can think of is to modify the doIt() code so that you refer to the parent elements in it explicitly , example: parent.document.getElementById(...

@nanodeathauthorAug 08.2006 — Alright...thanks...I can't have this stuff in a link though, since it has to just execute, not get clicked on. I'll figure something out.

@BrownBearAug 09.2006 — There are 2 ways I can think of:

1. IE specific:

parent.execScript("myfunction()","javascript")

  • 2. I tested it in IE and Firefox, it seems to work:

    parent.location.href="javascript:void(myfunction())"
    • Copy linkTweet thisAlerts:
    @nanodeathauthorAug 09.2006 — Alright, thanks muchly. That second idea hadn't occurred to me and seems like it would work (since it's basically like a force link, after all).

    @BrownBearAug 09.2006 — actually, I have not tried it, but if you would have a hidden image or div, you van assign ="javascript:void(myfunction())" as src for image or background image url for div - don't see why it should not work

    • [/QUOTE]    BUT - If myfunction() has a getElementById("mydivid") instruction in it, will it get the value of mydivid that resides in the parent, or the one which may, or may not, exist in the current frame?

    can you please provide a code for case? I am trying to figure out why "parent." not working for you.

    I attached files with testing of different methods of access. take a look at it.
