javascript - calling function from within same function -

-

i'm converting javascript code jquery , have come halt, heres code...
html:

<div id="text"></div>

javascript:

keywords = [ "one", "two", "three"] var allowed = true; function changetext ( ) {    if(allowed)    {       var keyword = keywords[ math.floor( math.random() * keywords.length ) ]       document.getelementbyid( "text" ).innerhtml = keyword;    }    settimeout( "changetext()", switchtime ); }  changetext();

jquery:

var changeallowed = true; $(document).ready(function changetext() {    if(changeallowed)    {       $("#text").fadeout(500);       var keyword = keywords[ math.floor( math.random() * keywords.length ) ];       $("#text").text(keyword).fadein(1000);    };    settimeout( "changetext()", 2000 ); }); changetext();

what should fade text out in new string (which on refresh) every 2 seconds or so, jquery effects working, seems settimeout() or i've not named function properly.

update

my first solution got out of synch when display queue got behind. here updated code uses callbacks timing right, along test fiddle:

var changeallowed = true; var keywords = ["test1", "test2", "test3", "test4", "test5"]; var hide = true;  var toggletextfade = function() {     if(changeallowed) {         var keyword =keywords[math.floor(math.random() * keywords.length)];          $("#text").text(keyword).fadein(1000,null,function(){             $("#text").fadeout(500,null,toggletextfade)});     }                };   $(document).ready(toggletextfade);

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
