Working in a view for a Document Library I enabled "inline-editing" and discovered that as any input-element receives focus the documents-ribbon-menu auto expands. This behavior is undesirable so my goal is to prevent the menu from auto expanding.

Through debugging I discovered suppressing window.SelectRibbonTab prevents this.

To resolve I created "test.aspx" so that when it is the current page the execution of window.SelectRibbonTab is suppressed, but all other page instances will remain unaffected. I attempted to pattern my override from these stack answers here & here but I'm unfamiliar with this concept and I am receiving a "Cannot assign to a function result" message.

Have a look at code below

window.SelectRibbonTab = function (obj) {
    if (location.pathname.search('test.aspx')=0) {
        return SelectRibbonTab.call(window, obj);

if (location.pathname.search('test.aspx') = 0) {

To this:

if (location.pathname.search('test.aspx') == 0) {

You are assigning zero to location.pathname.search('test.aspx'), not testing if it is zero.

Second part:

window.SelectRibbonTab = function (SelectRibbonTab) {
  return function ("Ribbon.Read", true) {
  if (location.pathname.search('test.aspx')==0) {
      return SelectRibbonTab.call(window, "Ribbon.Read", true);

I think this should work...I don't have a way to test it unfortunately.

FINAL Okay, so I finally figured it out :D

window.SelectRibbonTab = function (SelectRibbonTab) {
  return function (tabID, forced) {
  if (location.pathname.search('test.aspx')<0) {
      return SelectRibbonTab.call(window, tabID, forced);

Now, when you run the the function in the actual code (window.SelectRibbonTab("Ribbon.document")) I think it should run the custom function that you wrote (I hope).

  • Thank you - that resolved the Cannot assign to a function message however now I am receiving a SCRIPT5002: Function expected message. Commented Jun 24, 2014 at 13:02
  • Go into Firefox, and use the debugger to find the issue. It should tell you what is causing this error. Most likely, it is caused by a naming error, or type error.

  • Actually, I know what is causing this. I will write into my original answer to answer the second part

  • The idea behind this is that you are adding code onto the original function. So you are saying windows.SelectRibbonTab is now equal to the function that returns a constructor function, defining what action should be occuring.

  • I ran Second part: but received Expected Identifier message. I see where you're headed though ...I think I'm making a mess of the Closure, the method signature is function SelectRibbonTab(tabId, force) When watched tabId="Ribbon.Document" and force is omitted I can even execute SelectRibbonTab('Ribbon.Document') in the console causing the ribbon to auto-expand. But I'm not clear on how the parameters and method signature are expressed in the Closure. Thank you for your continued help. Commented Jun 24, 2014 at 14:39
