Internet Explorer 10隐藏按钮或阻止JavaScript工作？

Question

I'm not normally in a need to ask basic or vague JavaScript questions on SO, so pardon me if there is little details here - I'm not sure how to get more.

In the online user manual I'm maintaining, I'm adding custom buttons on each page to get a direct link to the current page (otherwise grabbing the URL just brings you to the home screen), as well as a few extra features. These buttons are added using Javascript, or rather they are already hidden in the HTML, are updated after an AJAX call and then displayed.

It has taken me a lot of work to get these working, in Firefox, Chrome, IE6, 7, 8, 9, I'm sure you know how these things go.

Now comes IE10 with yet another really weird behavior that I want to bang my head on the wall for. If you visit http://help.objectiflune.com/en/knowledgebase/ you will see those buttons on the right inside the main frame. They're grey and blue, top of the page.

So this first "welcome" page is fine, it works great, no issue. However, if you navigate to any sub page using the TOC on the left (such as Error Codes -> PlanetPress Design -> PlanetPress Design Error PXXXX), the buttons all disappear.

I've also noticed that if you get the URL for the page itself (inside the frame, again) and you open it in another tab, it first does not show them, but then refreshing the page makes the buttons appear.

I've tried using the F12 developper console, but it requires refreshing the page to show the console so I can`t use it in those new tabs. As for using within the whole frame system, it doesn't seem to be showing me any errors, nothing weird.

Again I'm sorry if this is an "it's not working" with no further technical details, but... there are none I know how to give.

UPDATE : For the specific code, please turn to http://help.objectiflune.com/common/scripts/olCommon.js , and look at the function starting at line 207 ( function buildMenu() ). this is the function that retrieves the information and displays the appropriate menus, such as $("#guidebuttons").show();

In ObjectifLune.css, #buttoncontainer has display: none . Navigating through the F12 window, the display of that object is none :

I would guess that somewhere in your JS, you're setting the display to block , but there's something wrong with that code in IE.
