readystatechange event ist useable for AUDIO, see http://msdn.microsoft.com/en-us/library/hh772923(v=vs.85).aspx javascript runs only on client, sou you must use interface to catch state of an element its events like readystatechange-event

constructor of "ype "m" is function manager(){...} m = new constructor (...) m is a pointer ! e.g. new Function(...) creates a pointer of a function new Function() is a member of Javascript predefines types (predefined constructor) so manager() runs like new Function() ? function manager() { var anObject = {prop1: 1, prop2: 2}; // local var !!!! // does not exists after the end of constructor // use global var ! . . . return { getMyObject: function(){ return anObject; } // local function !!!! // does not exists after the end of constructor // use global var to save the pointer. }

format of image must be compatible with browsers. Don't forget mime type (.httaccess file in folder of images) e.g. .gif image/gif .png image/png reload a page (f5) do not reload complete: browser cache may be filled. To test complete loading of page please clear browser cache at first. order of parsing a HTML page: At first HEAD included Javascript and so on AFTER and at last BODY included Javascript. In HEAD do not take a reference at this momen at this BODY must be parsed e.g. document.body object is created AFTER HEAD !! do not use document.body in Head if this reference called before BODY created (parsed).

you mean that in pure HTML and JavaScript please use attribut TILE too (value of TITLE should be not hte same like value of ALT). try onmouseover for IE onmousedown Fires when the user clicks the object with either mouse button. onmouseenter Fires when the user moves the mouse pointer into the object. onmouseleave Fires when the user moves the mouse pointer outside the boundaries of the object. onmousemove Fires when the user moves the mouse over the object. onmouseout Fires when the user moves the mouse pointer outside the boundaries of the object. onmouseover Fires when the user moves the mouse pointer into the object. onmouseup Fires when the user releases a mouse button while the mouse is over the object. onmousewheel Fires when the wheel button is rotated. ALT alt Sets or retrieves a text alternative to the graphic. SRC src Sets or retrieves a URL to be loaded by the object. ---------------------------------------------------------------------------- var ImgUrlOnMouseover='http://www.html-5.com/images/click-me-hover.png'; var ImgUrlOnMouseout='http://www.html-5.com/images/click-me-normal.png'; function ImgOnMouseXXX(IDOfIMG,state) // state // true onmouseover or onmouseenter // false onmouseout { // params are unchecked var PointerOfIMG; var SrcOfIMG=ImgUrlOnMouseout; // normal var PointerOfIMG=document.getElementById(IDOfIMG); if(PointerOfIMG!=null) { if(state){SrcOfIMG=ImgUrlOnMouseover); PointerOfIMG.src=SrcOfIMG; // need time to request data of img // if you want check time state use readyState } } for IE readyState Property Internet Development Index -------------------------------------------------------------------------------- Retrieves a value that indicates the current state of the object.

check emailAddress emailAddress null pointer ? property .value exists ? range of value of .value ? HTML funktion document.getElementById() uses param during parsing of document so '<%=hfEmail.ClientID%>' must be a real ID or filled BEFORE parsing javascript. put javascript at end of body, no in head (head is parsed at first before body). .... what you want //--> </script></pre> // where is <pre>

var TrueArray=new Array // numbers only of correct inputs ( 2, // 1 so fist input is correct, 2 so second input is correct ... // false second input is correct ); var TrueArrayLength=TrueArray.length; insert function onkeypress or onmousewover ... what you want 2 foot tall function GetTrueFalse(NumberOfQuestion,NumberOfCorrectfInput) // NumberOfQuestion from 1 to TrueArrayLength // NumberOfCorrectfInput value of field of array at index pos NumberOfQuestion-1 { NumberOfQuestion--; if((NumberOfQuestion>=0) && (NumberOfQuestion0) && (NumberOfCorrectfInput<3)) // 1 or 2 { if(NumberOfCorrectfInput==TrueArray[NumberOfQuestion]) // got number of correct input ? { // correct e.g. alert("bingo!"); } else { // not correct e.g. alert("nope"); } } } } have fun.

Don't use doument.write() During parsing parts of document (e.g. HEAD-part before body) browser finds script inside of BODY (browser parses body part). In this case the body object is real exist. document.write in use of Internet Explorer may create an NEW BODY and new document. To append objects inside actual document - actual body - please use Javascript functions createElement() and appendElement(). var X01=document.createElement("IMG"); if(X01!=null) {var X02=document.body.appendChild(X01); if (X02!=null) { // X02 is pointer of created object inside body } }

IE String Object (literal) (JScript) Allows manipulation and formatting of text strings and determination and location of substrings within strings. String is not a collection and not array. Use operator + or method concat. To convert a JScript-string into array use method split. To convert a numeric value into String use method parseInt. Syntax newString = new String(["stringLiteral"]) Arguments newString Required. The variable name to which the String object is assigned. stringLiteral Optional. Any group of Unicode characters. Remarks String objects can be created implicitly using string literals. String objects created in this fashion (referred to as standard strings) are treated differently than String objects created using the new operator. All string literals share a common, global string object. If a property is added to a string literal, it is available to all standard string objects: var alpha, beta; alpha = "This is a string"; beta = "This is also a string"; alpha.test = 10; In the previous example, test is now defined for beta and all future string literals. In the following example, however, added properties are treated differently: var gamma, delta; gamma = new String("This is a string"); delta = new String("This is also a string"); gamma.test = 10; In this case, test is not defined for delta. Each String object declared as a new String object has its own set of members. This is the only case where String objects and string literals are handled differently.

Only one way function close is a pre-defined property of window object. Please use event bubbling of close() and window. Insert a new funktion that recives this event what you want (event handler). Prototyping of a function ... try it. events of window (IE) Event Description onactivate Fires when the object is set as the active element. onafterprint Fires on the object immediately after its associated document prints or previews for printing. onbeforedeactivate Fires immediately before the activeElement is changed from the current object to another object in the parent document. onbeforeprint Fires on the object before its associated document prints or previews for printing. onbeforeunload Fires prior to a page being unloaded. onblur Fires when the object loses the input focus. oncontrolselect Fires when the user is about to make a control selection of the object. ondeactivate Fires when the activeElement is changed from the current object to another object in the parent document. onerror Fires when an error occurs during object loading. onfocus Fires when the object receives focus. onhelp Fires when the user presses the F1 key while the browser is the active window. onload Fires immediately after the browser loads the object. onmove Fires when the object moves. onmoveend Fires when the object stops moving. onmovestart Fires when the object starts to move. onresize Fires when the size of the object is about to change. onresizeend Fires when the user finishes changing the dimensions of the object in a control selection. onresizestart Fires when the user begins to change the dimensions of the object in a control selection. onscroll Fires when the user repositions the scroll box in the scroll bar on the object. onunload Fires immediately before the object is unloaded. methods of window (IE) Method Description alert Displays a dialog box containing an application-defined message. attachEvent Binds the specified function to an event, so that the function gets called whenever the event fires on the object. blur Causes the element to lose focus and fires the onblur event. clearInterval Cancels the interval previously started using the setInterval method. clearTimeout Cancels a time-out that was set with the setTimeout method. close Closes the current browser window or HTML Application (HTA). confirm Displays a confirmation dialog box that contains an optional message as well as OK and Cancel buttons. createPopup Creates a popup wind

.id is a property of html element (html DOM), not of a function this is the pointer of an instance like html element inside of html DOM. document.getElementById('A1').AddEventListener("click",Display_Info,false); --> this is the pointer of document.getElementById('A1') param of Display_Info is not exists like pointer or id-string-value

playlist and player are not the same. playlist in xml format --> script for datas. player in e.g. Javascript --> script for actions in use of datas. So the end of a song --> e.g. inside of player in use of javascript function for timers (duration of song). Please take Google to ceck possible players and owned playlist formats. HTML 5 audio player is inside of every modern browser. Playlist data in different ways possible. E.g. JSon, oder Array, oder xml (in use of xml DOM) or pure html code. If you want see my webpage (twseiten.com) for HTML-5-player or BGSOUND-Player (older MS Internet Explorer). In use of plugins like Flash or Java other players possible inside of HTML-5-Webpage. visual studio2010 .... in use of MS Internet Explorer: This browser may be not compatible to other browsers (e.g. webkit-browser Firefox, Opera becomes a webkit browser). Other IDE .. Eclipse for Javascript AND webkit browser useable. Often browsers have an own GUI to edit and debug html- and javasvcript code. Often only for webkit. JavaScript Based Radio Player - see above of this entry in forum.

client and server connections - use JAVA (Oracle), not JavaScript.

Streamed data Please use a server for streaming. Adobe server is not freeware. Adobe Action Script is not compatible every time (non compatibles upgrades and not cheap). WebM (HTML-5-audio) can be streamed. Ogg-format too. Security of streaming: Maybe server an folder of audio data must be on same host. Javacript only client language. WebM-player (streamed WebM too) is a component of html-5-browsers. Flash not. Player controls in use of JavaScript - yes. I have a webpage (twseiten.com) - there e.g. client side html-5-player but NOT streamed data.
