jQuery/Packer/ActiveX Activation

[anonymous]

Background

Inserting an ActiveX control (i.e. flash movie, quicktime movie) with an external javascript (i.e. jQuery) should avoid the ugly grey box and having to  click to activate.

Bug

ActiveX controls inserted using the packed version of jQuery have the grey box and must be activated. See:  jQuery/Packer/ActiveX Bug for more info.

Solution

I've narrowed the problem down to the jQuery.clean method, which uses a temporary div's innerHTML to convert html strings into DOM elements. Doing the conversion from unpacked code fixes the problem, so I'd like to suggest adding a convert hook inside jQuery.clean (see below for patch).

Without the hook, the entire jQuery.clean method has to be overwritten. With the hook, the bug could then be fixed by overwriting jQuery.clean.convert from outside of the packed code (i.e. via a plugin, or by copying and pasting jQuery.clean.convert = function(html) {...} at the bottom of jquery-latest.packed.js).

clean: function(a) {
	var r = [];
	
+	if(!jQuery.clean.convert)
+		jQuery.clean.convert = function(html) {
+			var n = document.createElement('div');
+			div.innerHTML = html;
+			return n;
+		};

	jQuery.each( a, function(i,arg){
		if ( !arg ) return;

		if ( arg.constructor == Number )
			arg = arg.toString();
		
		 // Convert html string into DOM nodes
		if ( typeof arg == "string" ) {
			// Trim whitespace, otherwise indexOf won't work as expected
-			var s = jQuery.trim(arg), div = document.createElement("div"), tb = [];
+			var s = jQuery.trim(arg), div, tb = [];

			var wrap =
				 // option or optgroup
				!s.indexOf("<opt") &&
				[1, "<select>", "</select>"] ||
				
				(!s.indexOf("<thead") || !s.indexOf("<tbody") || !s.indexOf("<tfoot")) &&
				[1, "<table>", "</table>"] ||
				
				!s.indexOf("<tr") &&
				[2, "<table><tbody>", "</tbody></table>"] ||
				
			 	// <thead> matched above
				(!s.indexOf("<td") || !s.indexOf("<th")) &&
				[3, "<table><tbody><tr>", "</tr></tbody></table>"] ||
				
				[0,"",""];

			// Go to html and back, then peel off extra wrappers
-			div.innerHTML = wrap[1] + s + wrap[2];
+			div = jQuery.clean.convert(wrap[1] + s + wrap[2]);
			
			// Move to the right depth
			while ( wrap[0]-- )
				div = div.firstChild;
			
			// Remove IE's autoinserted <tbody> from table fragments
			if ( jQuery.browser.msie ) {
				
				// String was a <table>, *may* have spurious <tbody>
				if ( !s.indexOf("<table") && s.indexOf("<tbody") < 0 ) 
					tb = div.firstChild && div.firstChild.childNodes;
					
				// String was a bare <thead> or <tfoot>
				else if ( wrap[1] == "<table>" && s.indexOf("<tbody") < 0 )
					tb = div.childNodes;

				for ( var n = tb.length-1; n >= 0 ; --n )
					if ( jQuery.nodeName(tb[n], "tbody") && !tb[n].childNodes.length )
						tb[n].parentNode.removeChild(tb[n]);
				
			}
			
			arg = div.childNodes;
		}

		if ( arg.length === 0 )
			return;
		
		if ( arg[0] == undefined )
			r.push( arg );
		else
			r = jQuery.merge( r, arg );

	});

	return r;
},

I think you meant to do: n.innerHTML = html;

instead of: div.innerHTML = html;

Yes, you're right John :-)

Are there plans to integrate this bug fix into the core? It seems it would only use a very few bytes and would have the benefit of allowing the highly useful flash plugin to run on jquery unpatched.

I would like to know if this bug will be solved any time soon, as the jqUploader plugin relies on the nice jquery.flash.js plugin. It would be great, as stated above, not to have to patch jquery core in order for this to run.

thanks !

We now provide a minified version of jQuery - you should recommend that your users use that instead (if you want to avoid activation.)
