IE post to iframe in HTA opens a new window

问题

There are a lot of posts about this topic but most of them are because IE doesn't set the attribute name dynamically.

I'm having a different trouble: I post a form (created dynamically) with an iframe as target. The first time it works great. Then I do it for a second time and IE opens a new window with the result of form's submission. I'm pretty sure it has to do with security issues because: if I create a simple HTML file (instead of a HTA) it works great. Also, if I run the same file that doesn't work locally (http://local.host/test.hta) it works great.

Any clue of whats going on or how can I fix it? Sadly its legacy code and I can't avoid using HTA or iframes and form submiting.

Here its the simple code:

                    first = true;

                $("#frame").unbind("load");
                $("#frame").load(function(){

                    if (first) {
                        first = false;
                        $("#frame")[0].contentWindow.document.cookie  = "testCookie=dummyValue";
                        $("<form></form>")
                            .attr("target", "frame").attr("method", "POST").attr("action", url)
                            .css("display", "none")
                            .appendTo($(document.body))
                            .append('<input type="hidden" name="dummy" value="dummy" />')
                            .submit();
                        return;
                    }

                    // Other stuff

                });

                $("<form></form>")
                    .attr("target", "frame").attr("method", "POST").attr("action", url)
                    .css("display", "none")

                    .append('<input type="hidden" name="dummy" value="dummy" />')
                    .submit();

回答1:

You can try to use application="yes" attribute within iframe tag. Iframes without the said attribute are considered as unsafe in HTA, and all interaction between iframe and main window is blocked.
