Enable Save in IE9 mode

Wouldn’t it be nice to use html5 and css3 in SharePoint? No problems, there is actually v5 master out there, created by Kyle Schaefer. Or just use h5ml5 and css3 right away in your webparts and pages. But there is a big problem. It doesn’t work in IE9–. One of the issues (even listed by Kyle) is that “save” doesn’t work in modal dialogs where Rich Text Editor is used. Especialy it is for modal dialogs.

The problem is not IE9, neither html5 and css3. After some digging in javascript code which is shipped with SharePoint I found out that the problem is some legacy javascript code which is not supported by IE9 but in IE8– (and compatibility mode).

When we set IE9 mode in IE9 Dev Tools (F12) and go to Tasks list and try to create a task, we’ll get an error:

It is RTE_GetEditorIFrame from init.js:

function RTE_GetEditorIFrame(strBaseElementID)
{ULSopi:;
	var ifmEditor=null;
	var doc=document;
	if ((null !=doc.frames) && (doc.frames.length==0) && (doc.parentWindow.parent !=null))
	{
		doc=doc.parentWindow.parent.document;
	}
	if ((null !=doc.frames) && (doc.frames.length > 0))
	{
		var ifmContainer=doc.getElementById(RTE_GetEditorIFrameID(strBaseElementID));
		if (ifmContainer !=null)
		{
			ifmEditor=doc.frames(RTE_GetEditorIFrameID(strBaseElementID));
		}
	}
	return ifmEditor;
}

So it is document.frames(“…”), not the usual document.frames[“…”]. What is that VB-style about?

Okay, the reason why this error isn’t raised in other browsers is just because this weird code isn’t run (Try to set break point there in Chrome or Firefox). And that’s why you never see Rich Text Editor toolbar in EditForm.aspx in Chrome and Firefox. To prove this, try to remove the Rich Text Column in your list. Then you can use “Save” button again, with IE9 mode!

Now we know the reason. How can we solve it. To do so we must find out where javascript defines whether to run or not Rich Text Editor toolbar.

First RTE_GetEditorIframe is invoked by RTE_ConvertTextAreaToRichEdit which is invoked by an inline script directly from NewForm.aspx:

if (browseris.ie5up 
  && (browseris.win32 || browseris.win64bit) 
    && !IsAccessibilityFeatureEnabled()){
    RTE_ConvertTextAreaToRichEdit("ctl00_m_g_0a9abd43_19a2_461e_b46f_6a1ae22a7ff1_ctl00_ctl05_ctl06_ctl00_ctl00_ctl04_ctl00_ctl00_TextField"
      , true, false, "", "1044", null, true, null, null, null
        ,"Compatible", "\u002ft001",null,null,null,null);
    }
else{
  document.write(" <br /><span class=\"ms-formdescription\"><a href='javascript:HelpWindowKey(\"nsrichtext\")'>Klikk her for hjelp med å legge til grunnleggende HTML-formatering.</a></span> <br />");
};

So there it is where the fishy code is invoked. Okay how can we intervene here to enable Save button? All solutions are based on disabling the bad code which is used to “convert” textarea to RichEdit.

1. Solution number one override RTE_ConvertTextAreaToRichEdit, just in style:

function RTE_ConvertTextAreaToRichEdit() {};

2. Solution number two: override IsAccessibilityFeatureEnabled, or this one:

function SetIsAccessibilityFeatureEnabled(f)
{ULSA13:;
	if (f)
		document.cookie="WSS_AccessibilityFeature=true;path=/;";
	else
		document.cookie="WSS_AccessibilityFeature=false;path=/;";
	var hiddenAnchor=document.getElementById("HiddenAnchor");
	var event;
	if (browseris.ie)
		event={ "srcElement" : hiddenAnchor , "fakeEvent" : 1, "enableStatus" : f};
	else
		event={ "target" : hiddenAnchor , "fakeEvent" : 1, "enableStatus" : f};
	if (hiddenAnchor==null || hiddenAnchor.onclick==null)
		return;
	hiddenAnchor.onclick(event);	
}

So to fool Accessibility, just set your own cookie: document.cookie=”WSS_AccessibilityFeature=true;path=/;”. But: don’t do that. It is really bad idea. Many features will stop working.

3. Solution number three is to override browseris. browseris is a browser which holds the information about the browser, simple. Here is how it is defined in init.js:

function Browseris () {ULSA13:;
	var agt=navigator.userAgent.toLowerCase();
	this.osver=1.0;
	if (agt)
	{
		var stOSVer=agt.substring(agt.indexOf("windows ")+11);
		this.osver=parseFloat(stOSVer);
	}
	this.major=parseInt(navigator.appVersion);
	this.nav=((agt.indexOf('mozilla')!=-1)&&((agt.indexOf('spoofer')==-1) && (agt.indexOf('compatible')==-1)));
	this.nav6=this.nav && (this.major==5);
	this.nav6up=this.nav && (this.major >=5);
	this.nav7up=false;
	if (this.nav6up)
	{
		var navIdx=agt.indexOf("netscape/");
		if (navIdx >=0 )
			this.nav7up=parseInt(agt.substring(navIdx+9)) >=7;
	}
	this.ie=(agt.indexOf("msie")!=-1);
	this.aol=this.ie && agt.indexOf(" aol ")!=-1;
	if (this.ie)
		{
		var stIEVer=agt.substring(agt.indexOf("msie ")+5);
		this.iever=parseInt(stIEVer);
		this.verIEFull=parseFloat(stIEVer);
		}
	else
		this.iever=0;
	this.ie4up=this.ie && (this.major >=4);
	this.ie5up=this.ie && (this.iever >=5);
	this.ie55up=this.ie && (this.verIEFull >=5.5);
	this.ie6up=this.ie && (this.iever >=6);
	this.ie7down=this.ie && (this.iever =7);
	this.ie8standard=this.ie && document.documentMode && (document.documentMode==8);
	this.winnt=((agt.indexOf("winnt")!=-1)||(agt.indexOf("windows nt")!=-1));
	this.win32=((this.major >=4) && (navigator.platform=="Win32")) ||
		(agt.indexOf("win32")!=-1) || (agt.indexOf("32bit")!=-1);
	this.win64bit=(agt.indexOf("win64")!=-1);
		this.win=this.winnt || this.win32 || this.win64bit;
	this.mac=(agt.indexOf("mac")!=-1);
	this.w3c=this.nav6up;
	this.safari=(agt.indexOf("webkit")!=-1);
	this.safari125up=false;
	this.safari3up=false;
	if (this.safari && this.major >=5)
	{
		var navIdx=agt.indexOf("webkit/");
		if (navIdx >=0)
			this.safari125up=parseInt(agt.substring(navIdx+7)) >=125;
		var verIdx=agt.indexOf("version/");
		if (verIdx >=0)
	            this.safari3up=parseInt(agt.substring(verIdx+8)) >=3;
	}
	this.firefox=this.nav && (agt.indexOf("firefox") !=-1);
	this.firefox3up=false;
	this.firefox36up=false;
	if (this.firefox && this.major >=5)
	{
	    var ffVerIdx=agt.indexOf("firefox/");
	    if (ffVerIdx >=0)
	    {
		var firefoxVStr=agt.substring(ffVerIdx+8);
	        this.firefox3up=parseInt(firefoxVStr) >=3;
		this.firefox36up=parseFloat(firefoxVStr) >=3.6;
	    }
	}
}
var browseris=new Browseris();
var bis=browseris;

So to fool this, just set:

 var browseris = {};

But you have to do it after init.js, so wrap into ExecuteOrDelayUntilScriptLoaded:

ExecuteOrDelayUntilScriptLoaded(function() { 
  var browseris = {}; 
}, "init.js");

After that you can press Save button. You’ll lose the Rich Text Editor, but you’ll have the nice features from CSS3.

DISCLAIMER: It is just an exploration lab. There is no warranty that it will work across the whole site. Don’t ever do such things things at home!

css3 fixers

If you just want to use css3 in your design and still use team functionality, take a look on pie.htc, jQuery.corner or iecss3.

 

Update 2015-09-16 Other Related Issues

Recently me and my colleague had to fix this issue again in SharePoint 2010. What we found was failing select elements (Choice field or Lookup field) in forms. There are some js functions that do not run in other web browsers rather than in IE in IE9 mode. All fail because of the inability of getting custom html element attributes.


//This is an override of FilterChoice (in core.js)
//We override this line: var strOpts=ctrl.choices; -> var strOpts=ctrl.getAttribute("choices");
//The reason is that this does not work in IE9 mode
//Don't forget this workaround. It might lead to other problems
function FilterChoice_new(opt, ctrl, strVal, filterVal) {
   var i;
   var cOpt=0;
   var bSelected=false;
   var strHtml="";
   var strId=opt.id;

   var strMatchVal="";

   var rgopt=strOpts.split("|");
   var x=AbsLeft(ctrl);
   var y=AbsTop(ctrl)+ctrl.offsetHeight;
   var elmWorkspace=document.getElementById("s4-workspace");
   if(elmWorkspace)
                                y -=AbsTop(elmWorkspace);
