I wants to access server web page which data is continuously growing(streaming data), I want to buffered some of that data write it in responseText then again get next buffered data write it and so on (in AJAX).
View 3 RepliesI am going to use the server push
for streaming the data by keeping the connection open. At client side,
i am having the XMhttprequest object (i.e ActiveX object of IE). When
the data comes, onreadystatechange method get callback on state 3 but
it doesn't allow me to read the data from the object. It says 'The data
necessary to complete this operation is not yet available'. Is it
possible to read the streaming data from the XMLHttprequest object in
IE?
I know Mozilla supports to read the data, when the ready state is 3. In
Internet Explorer, how we can use the XMLhttp Active object to read the
streaming data.
I am playing with the XMLHTTPRequest method to perform client/server
transactions. I have it set up right now so that when readyState is 4,
it takes the XML and processes it. This works great until there is alot
of data. In that case, the user will have to wait for the data to come
back which may take a minute or so.
I don't want the user to have to wait. Is it possible for javascript to
periodically (while still receiving more data) stop and display what it
has received thus far? I guess this would be considered a type of
streaming.
In mozilla/firefox, I have read that I can use readyState 3 to run my
callback function every 4096 bytes. I can then take those 4K, parse
them, and then continue on. However I have also read that IE cannot do
this. Since I need this to work in IE, is there a workaround?
I have a project that I need to read some data from an XML file.
Something like:
However, since JS is a client side script so it can't read from client side, is there any alternate way to do this? I am thinking to create a "Data" class, and many "Data" objects, is this an elegant way to do it?
i am trying to read the data of a javascript variable using a php variable.
Code:
<script>
var fName = "first name";

for example there is site with address www.X.com, that has the price of some product:<div id="product1">price: 100$</div>now I wanna make site www.Y.com and then, I wanna read the price of product1 which is in the site www.X.comwe can read the value in the html site with javascript command like this:String s = document.getElementById("product1").valuebut how can we read this value in out of that site automatically?

View 2 Replies View RelatedI am working on a simple tool for my office.We have a very huge database with 5000 tables. All the tables, Columns and their attributes are stored in to excel sheet.
Tool I am designing is for mapping between front end and back end values. Now I will use an image (front end screen of our application) , when user clicks it, I need the HTML to access the excel sheet and display the back end field,the name of tables it can be found in and other data related to that field
Simply,I want to pull data from excel and display them differently for each different click. I want to pass the parameter on click and filter a column in excel with it and display the entire set of sheet with this criteria. Is this possible? or am I expecting too much

View 1 Replies View RelatedI have a streaming audio feature set up using a M3u file and a bunch of
MP3's: http://www.motorcityrock.com/mcr_radio/mcr_radio.html. When then
visitor clicks on the link the M3u kicks in and the songs play in the
pre-determined order. That works great, but everytime a visitor clicks the
link the songs start from the beginning. Is there a simple way (using
Javascript or?) to keep the M3u "running" in the background all the time so
that all visitors will hear the same song at the same time...just like a
traditional radio station?
Is it possible to stream XML data from a file using AJAX?
The xml file is constantly being updated by a backend program, I currently have a javascript that has a timer, every second it just runs a loadXML() function to return the XML data however having a few problems with the javascript tripping over itself.
Wondering if AJAX has streaming abilities?
Also, can someone please clarify for me, is the xml dom javascript, or ajax? As I have just read a ajax book that tells you to use xmldom to read xml data but im already doing that, with javascript, what is the difference?
I have just uplaoded my web page and I have having problems playing my files. The entire page works well on the hard drive but dosn't work after I upload it. I assume the problem must be to do with the streaming.

Do you know where the problem is? One thing that I must say is that the tutorial (where I took it from) worked with a wav-file, as you can see I work with a streaming file (asx-file).
I want to stream audio into a hidden frame and load, stop, and control
volume via JavaScript. I'm thinking w/ Windows Media Player.
i have a form with a 'name', 'date', 'type', 'style', 'color' and 'result' field.let's say the user inputs "jones" in the name field, "8/1/2011" in the date field, "new" in the type field, and 'modern' in the style field.i want the 'result' field to take a look at the 'name' field, and if the 'name' field has a particular text, let's say (in this case) "jones", the javascript code will then place the contents of 'date', 'type' and 'style' fields, along with hardwired text like "the information you are looking for is 'date', 'type' and 'style'" into the 'result' field.

View 3 Replies View RelatedI am using .ajax() to access cross-domain data using JSONP. Because I need to be able to cache the data I want to use a static name for thejsonpCallback function, so I have set the jsonpCallback option in the .ajax() request. However that appears to requires a global function whereas the auto generated function didn't (well maybe it did but that was all hidden from me).
I definitely need to be able to cache the results. Ideally I wouldn't have a global function handling the data. Is there another way to do this? If not what is the best practice way to go about using a global function these days and how do I provide it with the context of the object/module it was called from - which is where the data is needed?
Relatively new to jQuery but have a problem with getting data to display.Using a webform with 2 forms. User slects and inputs data into the first form, clicks a button then using jQuery .ajax submits the serialized data to a php script. The script processes the input into multiple paragraphs of text which is based on the input from the first form.The data is returned to the webpage and displayed in a text area (of the 2nd form) where the user can edit it to fine tune the wording. The 2 forms are displayed in different tabs so it is easy to move back and forward between the 2 forms.
The problem occurs when the user goes back to the first form and enters or selects different text and then click the submit button to generate a whole new text for insertion into the textarea on the second form. For certain fields the modified text is displayed.However if the whole of the text in the textarea is deleted, then the user clicks the submit button to re-generate the text content area then nothing at all is ever interted into the textarea. If have user alert to check that data is returned from the php handler and this text is correct. BUT when I click on the tab to see the textarea (id is "draftrec") there is no text inserted. The relevant function is below and the line that should insert the text into the textarea is:
$("textarea#draftrec").html(data).show();
//------------------------------------------------------
$("form#form1").submit(function(e){

I want to read a pre tag with xml. I am working client side. I have tried everything. The <title> tag gets lost with innerHTML(ok in FF only). I tried traversing the dom and putting in the tag names but the title tag is ignored. I am trying to syntax highlight this. Everything works if I do not use certain html tags. How do I get raw text from the pre? The text would come from one of two sources, a server or inputted into a textarea by the user. It is dynamically placed in the div tag and then processed.

This is working fine on itself. What is does is when I click a link it loads data into the following div. When done loading it slides out. But I want to change the appearance of the slide. I have tried to do that like this: $(this).show("slide", { direction: "down" }, 1000); But this doesn't work. When I check firebug it says the following: o.easing[this.options.easing || (o.easing.swing ? "swing" : "linear")] is not a function
