javascript - Jquery returns a list using id selector -

-

i'm having trouble jquery , selectors using following code:

<div id="test"></div> console.log($('#test'));

this returns list [<div id=​"test">​</div>​] instead of single element.

this results on having write $('#test')[0] every operations instead of $('#test'). idea on why?

regards

jquery not return htmlelement, returns jquery object.

a jquery object contains collection of document object model (dom) elements have been created html string or selected document. since jquery methods use css selectors match elements document, set of elements in jquery object called set of "matched elements" or "selected elements"

the jquery object behaves array; has length property , elements in object can accessed numeric indices [0] [length-1]. note jquery object not javascript array object, not have methods of true array object such join(). http://api.jquery.com/types/#jquery

this example of composite design pattern

the composite pattern describes group of objects can treated in same way single instance of object can. implementing pattern allows treat both individual objects , compositions in uniform manner. in jquery, when we're accessing or performing actions on single dom element or group of dom elements, can treat both in uniform manner. http://www.addyosmani.com/resources/essentialjsdesignpatterns/book/#designpatternsjquery

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...
