  • NHibernate Entity code conversion from #C to VB.Net

    - by CoderRoller
    Hello and thanks for your help in advance. I am starting on the NHibernate world and i am experimenting with the NHibernate CookBook recipes, i am trying to set a base entity class for my entities and this is the C# code for this. I would like to know whats the VB.NET version so i can implement it in my sample project. This is the C# code: public abstract class Entity<TId> { public virtual TId Id { get; protected set; } public override bool Equals(object obj) { return Equals(obj as Entity<TId>); } private static bool IsTransient(Entity<TId> obj) { return obj != null && Equals(obj.Id, default(TId)); } private Type GetUnproxiedType() { return GetType(); } public virtual bool Equals(Entity<TId> other) { if (other == null) return false; if (ReferenceEquals(this, other)) return true; if (!IsTransient(this) && !IsTransient(other) && Equals(Id, other.Id)) { var otherType = other.GetUnproxiedType(); var thisType = GetUnproxiedType(); return thisType.IsAssignableFrom(otherType) || otherType.IsAssignableFrom(thisType); } return false; } public override int GetHashCode() { if (Equals(Id, default(TId))) return base.GetHashCode(); return Id.GetHashCode(); } } I tried using an online converter but puts a Nothing reference in place of default(TId) that doesn't seem right to me that's why I request for help: Private Shared Function IsTransient(obj As Entity(Of TId)) As Boolean Return obj IsNot Nothing AndAlso Equals(obj.Id, Nothing) End Function I Would appreciate the insight you may give me on the subject.

  • Using NHibernate's HQL to make a query with multiple inner joins

    - by Abu Dhabi
    The problem here consists of translating a statement written in LINQ to SQL syntax into the equivalent for NHibernate. The LINQ to SQL code looks like so: var whatevervar = from threads in context.THREADs join threadposts in context.THREADPOSTs on threads.thread_id equals threadposts.thread_id join posts1 in context.POSTs on threadposts.post_id equals posts1.post_id join users in context.USERs on posts1.user_id equals users.user_id orderby posts1.post_time where threads.thread_id == int.Parse(id) select new { threads.thread_topic, posts1.post_time, users.user_display_name, users.user_signature, users.user_avatar, posts1.post_body, posts1.post_topic }; It's essentially trying to grab a list of posts within a given forum thread. The best I've been able to come up with (with the help of the helpful users of this site) for NHibernate is: var whatevervar = session.CreateQuery("select t.Thread_topic, p.Post_time, " + "u.User_display_name, u.User_signature, " + "u.User_avatar, p.Post_body, p.Post_topic " + "from THREADPOST tp " + "inner join tp.Thread_ as t " + "inner join tp.Post_ as p " + "inner join p.User_ as u " + "where tp.Thread_ = :what") .SetParameter<THREAD>("what", threadid) .SetResultTransformer(Transformers.AliasToBean(typeof(MyDTO))) .List<MyDTO>(); But that doesn't parse well, complaining that the aliases for the joined tables are null references. MyDTO is a custom type for the output: public class MyDTO { public string thread_topic { get; set; } public DateTime post_time { get; set; } public string user_display_name { get; set; } public string user_signature { get; set; } public string user_avatar { get; set; } public string post_topic { get; set; } public string post_body { get; set; } } I'm out of ideas, and while doing this by direct SQL query is possible, I'd like to do it properly, without defeating the purpose of using an ORM. Thanks in advance! EDIT: The database looks like this: http://i41.tinypic.com/5agciu.jpg (Can't post images yet.)

  • Adding dynamic content with events in jquerymobile

    - by Christian Waidner
    Currently I'm stuck with a problem in jquerymobile: I'm adding items to a list dynamically and use enhanceWithin() in the end (so styling is correct). After this I like to add click-events for each list item but the problem is, that enhanceWithin runs asynchronous and so I always get the error message "cannot call methods on checkboxradio prior to initialization; attempted to call method 'refresh'" When I delay the event-adding-code it works perfectly. Does anyone have an idea if there is a enhanceWithin.done event or anything else I can use? HTML: ... <div id="shoppinglist">Loading list...</div> ... Javascript: function updateList() { var result = ""; $.each(shoppinglistItems, function (index, item) { result += '<label><input type="checkbox" ' + item.checked + ' id="item_' + item.id + '">' + item.name + '</label>\n'; }); $('#shoppinglist').html(result).enhanceWithin(); // Change-Events an die Checkboxen knoten $('input[id*=item_]').unbind('change').bind('change', function (event) { var itemid = $(this).attr('id'); itemid = (itemid.split('_'))[1]; // Nur die Zahl extrahieren // Passendes Item aus der Liste der Items suchen und checken $.each(shoppinglistItems, function (index, item) { if (item.id == itemid) { item.checked = "checked"; item.timestamp = moment().format("YYYYMMDDHHmmss"); } }); updateList(); }); }

  • Image resizing efficiency in C# and .NET 3.5

    - by Matthew Nichols
    I have written a web service to resize user uploaded images and all works correctly from a functional point of view, but it causes CPU usage to spike every time it is used. It is running on Windows Server 2008 64 bit. I have tried compiling to 32 and 64 bit and get about the same results. The heart of the service is this function: private Image CreateReducedImage(Image imgOrig, Size NewSize) { var newBM = new Bitmap(NewSize.Width, NewSize.Height); using (var newGrapics = Graphics.FromImage(newBM)) { newGrapics.CompositingQuality = CompositingQuality.HighSpeed; newGrapics.SmoothingMode = SmoothingMode.HighSpeed; newGrapics.InterpolationMode = InterpolationMode.HighQualityBicubic; newGrapics.DrawImage(imgOrig, new Rectangle(0, 0, NewSize.Width, NewSize.Height)); } return newBM; } I put a profiler on the service and it seemed to indicate the vast majority of the time is spent in the GDI+ library itself and there is not much to be gained in my code. Questions: Am I doing something glaringly inefficient in my code here? It seems to conform to the example I have seen. Are there gains to be had in using libraries other than GDI+? The benchmarks I have seen seem to indicate that GDI+ does well compare to other libraries but I didn't find enough of these to be confident. Are there gains to be had by using "unsafe code" blocks? Please let me know if I have not included enough of the code...I am happy to put as much up as requested but don't want to be obnoxious in the post.

  • Jquery - Setting form select-field "selected" value only works after refresh

    - by frequent
    Hi, I want to use a form select-field for users to select their country of residence, which shows the IP based country as default value (plus the IP address next to it); Location info (ipinfodb.com) is working. I'm passing "country" and "ip" to the function, which should modify select-field and ip adress Problem: IP adress works, but the select-field only updates after I hit refresh. Can someone tell me why? Here is the code: HTML <select name="setup_changeCountry" id="setup_changeCountry"> <option value="AL-Albania">Albanien</option> <option value="AD-Andorra">Andorra</option> <option value="AM-Armenia">Armenien</option> <option value="AU-Australia">Australien</option> ... </select> <div class="setup_IPInfo"> <span>Your IP</span> <span class="ipAdress"> -- ip --</span> </div> Javascript/Jquery function morph(country,ip) >> passed from function, called on DOMContentLoaded { var ipAdress = ip; $('.ipAdress').text(ipAdress); var countryForm = country; $('#setup_changeCountry option').each(function() { if ($(this).val().substr(0,2) == countryForm) { $(this).attr('selected', "true"); } }); } Thanks for any clues on how to fix this.

  • Why my jquery function is not firing on Firefox

    - by Cristian Boariu
    I have some trouble with some jquery method (for some checkboxes I want them to fire on checked/unchecked so I can do something then). This method works perfectly on Chrome and IE but not on latest FF. jQuery(function () { jQuery(':checkbox').change(function () { var counter = jQuery('.count').text(); var thisCheck = jQuery(this); if (thisCheck.is(':checked')) { counter++; //apply green color to the selected row jQuery(this).closest('tr').addClass('checked'); } else { counter--; //remove green color to the selected row jQuery(this).closest('tr').removeClass('checked'); } jQuery('.count').html(counter); //enable export button when there are selected emails to be exported if (counter > 0) { jQuery(".exportButton").removeAttr("disabled", ""); } else { jQuery(".exportButton").attr("disabled", "disabled"); } }); }); Basically it's simply not firing...Even with Debug is not catching the first line (function declare nor other lines too). If I move this javascript(without function declare) inside jQuery(document).ready(function ($) { all works nice on Firefox too... Yes, I do use jQuery.noConflict(); before jQuery(document).ready(function ($) { Do you know why this happens?

  • Change jQuery slider option dynamically based on window width

    - by Nathan
    I would like to change a jQuery option based on window width (on load as well as on resize). I've found solutions close to what I need, but I don't understand jQuery or javascript enough to customize them for my needs. Here's my jQuery code: <script type="text/javascript"> var tpj = jQuery; tpj.noConflict(); tpj(document).ready(function () { if (tpj.fn.cssOriginal != undefined) tpj.fn.css = tpj.fn.cssOriginal; tpj('#rev_slider_1_1').show().revolution({ delay: 5000, startwidth: 1920, startheight: 515, hideThumbs: 200, thumbWidth: 100, thumbHeight: 50, thumbAmount: 4, navigationType: "bullet", navigationArrows: "verticalcentered", navigationStyle: "navbar", touchenabled: "on", onHoverStop: "off", navOffsetHorizontal: 0, navOffsetVertical: 20, shadow: 0, fullWidth: "on" }); }); //ready </script> I want to change the startheight based on window width. If the window width is above 1280 I would like the value for the height to be 515, and if it is below 1280 I would like the height to be 615 and if the width is less than 480 make the height 715. With help from another post I am able to change the css I need using this script: $(window).on('load resize', function () { var w = $(window).width(); $("#rev_slider_1_1 #rev_slider_1_1_wrapper") .css('max-height', w > 1280 ? 515 : w > 480 ? 615 : 715); }); But I need to also change the jQuery startheight value on the fly. Can someone help? Thanks!

  • Ruby - RegEx problem or maybe another solution altogether

    - by r3nrut
    Ok the problem I'm having is that I have a block of javascript I've successfully scraped out of a websites source and now I have to sift through the js to get the specific values I'm looking for. Below is the chunk i'm needing to deal with. I need to find "flvFileName" and get all the file names listed. In this case its: trailer1,trailer2,trailer3. At first I started using regex to match the start and end tags and them match the file names and extract them to an array but the problem is that there isn't always 3 videos in the list. Could be 0, 1, 2, 3, 4 etc. So matching doesn't work. Any thoughts on a way to approach this that won't make me continue to abuse my laptop? ["", "\r\n", "\n", "\r\n function IgnoreEnter(e) {\r\n var code;\r\n if (!e) // IE\r\n {\r\n var e = window.event;\r\n }\r\n if (e.keyCode) {\r\n code = e.keyCode;\r\n }\r\n else if (e.which) // Firefox, Opera\r\n {\r\n code = e.which;\r\n }\r\n\r\n if (code == 13) {\r\n e.cancelBubble = true;\r\n e.returnValue = false;\r\n }\r\n }\r\n\r\n function ResetDefault() {\r\n __defaultFired = false;\r\n }\r\n", "", "\r\n// <![CDATA[\r\n$(doc).ready(function () { $('#VideoObject').flash({ swf: '/scinema/video.swf', height: 300, width: 480, hasVersion: 8, menu: false, wmode: 'transparent', bgcolor: '#000',flashvars: {flvFileName: 'trailer1,trailer2,trailer3', age: 'no', isForced: 'true'} }); });

  • JQuery/AJAX: Loading external DIVs using dynamic content

    - by ticallian
    I need to create a page that will load divs from an external page using Jquery and AJAX. I have come across a few good tutorials, but they are all based on static content, my links and content are generated by PHP. The main tutorial I am basing my code on is from: http://yensdesign.com/2008/12/how-to-load-content-via-ajax-in-jquery/ The exact function i need is as follows: Main page contains a permanent div listing some links containing a parameter. Upon click, link passes parameter to external page. External page filters recordset against parameter and populates div with results. The new div contains a new set of links with new parameters. The external div is loaded underneath the main pages first div. Process can then be repeated creating a chain of divs under each other. The last div in the chain will then direct to a new page collating all the previously used querystrings. I can handle all of the PHP work with populating the divs on the main and external pages. It's the JQuery and AJAX part i'm struggling with. $(document).ready(function(){ var sections = $('a[id^=link_]'); // Link that passes parameter to external page var content = $('div[id^=content_]'); // Where external div is loaded to sections.click(function(){ //load selected section switch(this.id){ case "div01": content.load("external.php?param=1 #section_div01"); break; case "div02": content.load("external.php?param=2 #section_div02"); break; } }); The problem I am having is getting JQuery to pass the dynamically generated parameters to the external page and then retrieve the new div. I can currently only do this with static links (As above).

  • Javascript get image height works in all browsers but firefox...please help?

    - by Calvin
    So I am fairly new to Javascript (a lot of experience in PHP), but I have this basic script that checks a link that redirects to a URL to see what the image height is. If it is a certain height then it adds one to a variable, otherwise nothing. I would easily do this in PHP but the images are on other servers and not my own so it doesn't work. Anyways, ehre is the script. Let me know if you have any tips. Works well and tested in Chrome, Safari, Opera, and IE. <script language='JavaScript'> window.onload = function() { var nstar = 0, urls = []; urls[0] = "http://optout.imiclk.com/cgi/nai_status.cgi?nocache="; urls[1] = "http://www.adbrite.com/mb/nai_optout_check.php?nocache="; urls[2] = "http://events.adchemy.com/visitor/auuid/nai-status?nocache="; function getImgSize(imgSrc){ var newImg = new Image(); newImg.src = imgSrc; return{height:newImg.height, width:newImg.width} } for(i=0,length=urls.length;i<length;i++){ if(getImgSize(urls[i]).height==43){nstar++;} } document.getElementById('tracknum').innerHTML = "<b>" + nstar + "</b>"; } </script>

  • (closed) nodejs responding an image (via pipe and response.end()) leads into strange behaviour

    - by johannesboyne
    What the Problem was: I had 2 different writeStreams! If WriteStram#1 is closed, the second should be closed too and then it all should be piped... BUT node is asynchronious so while one has been closed, the other one hasn't. Even the stream.end() was called... well you always should wait for the close event! thx guys for your help! I am at my wit's end. I used this code to pipe an image to my clients: req.pipe(fs.createReadStream(__dirname+'/imgen/cached_images/' + link).pipe(res)) it does work but sometimes the image is not transferred completely. But no error is thrown neither on client side (browser) nor on server side (node.js). My second try was var img = fs.readFileSync(__dirname+'/imgen/cached_images/' + link); res.writeHead(200, { 'Content-Type' : 'image/png' }); res.end(img, 'binary'); but it leads to the same strange behaviour... Does anyone got a clue for me? Regards! (abstracted code...) var http = require('http'); http.createServer(function (req, res) { Imgen.generateNew( 'virtualtwins/www_leonardocampus_de/overview/28', 'www.leonardocampus.de', 'overview', '28', null, [], [], function (link) { fs.stat(__dirname+'/imgen/cached_images/' + link, function(err, file_info) { if (err) { console.log('err', err); } console.log('file info', file_info.size); res.writeHead(200, 'image/png'); fs.createReadStream(__dirname+'/imgen/cached_images/' + link).pipe(res); }); } ); }).listen(13337, '127.0.0.1'); Imgen.generateNew just creates a new file, saves it to the disk and gives back the path (link)

  • What are the benefits of a classical structure over a prototyple one?

    - by Rixius
    I have only recently started programming significantly, and being completely self-taught, I unfortunately don't have the benefits of a detailed Computer science course. I've been reading a lot about JavaScript lately, and I'm trying to find the benefit in classes over the prototype nature of JavaScript. The question seems to be drawn down the middle of which one is better, and I want to see the classical side of it. When I look at the prototype example: var inst_a = { "X": 123, "Y": 321, add: function () { return this.X+this.Y; } }; document.write(inst_a.add()); And then the classical version function A(x,y){ this.X = x; this.Y = y; this.add = function(){ return this.X+this.Y; }; }; var inst_a = new A(123,321); document.write(inst_a.add()); I begun thinking about this because I'm looking at the new ecmascript revision 5 and a lot of people seem up in arms that they didn't add a Class system.

  • Trouble defining method for Javascript class definition.

    - by btoverdrive
    I'm somewhat new to object oriented programming in Javascript and I'm trying to build a handler object and library for a list of items I get back from an API call. Ideally, I'd like the library functions to be members of the handler class. I'm having trouble getting my class method to work however. I defined as part of the class bcObject the method getModifiedDateTime, but when I try to echo the result of the objects call to this method, I get this error: Error on line 44 position 26: Expected ';' this.getModifiedDateTime: function(epochtime) { which leads me to believe that I simply have a syntax issue with my method definition but I can't figure out where. response( { "items": [ {"id":711,"name":"Shuttle","lastModifiedDate":"1268426336727"}, {"id":754,"name":"Formula1","lastModifiedDate":"1270121717721"} ], "extraListItemsAttr1":"blah", "extraListItemsAttr2":"blah2" }); function response(MyObject) { bcObject = new bcObject(MyObject); thing = bcObject.getModifiedDateTime(bcObject.videoItem[0].lastModifiedDate); SOSE.Echo(thing); } function bcObject(listObject) { // define class members this.responseList = {}; this.videoCount = 0; this.videoItem = []; this.responseListError = ""; // instantiate members this.responseList = listObject; this.videoCount = listObject.items.length; // populate videoItem array for (i=0;i<this.videoCount;i++) { this.videoItem[i] = listObject.items[i]; } this.getModifiedDateTime: function(epochtime) { var dateStringOutput = ""; var myDate = new Date(epochtime); dateStringOutput = myDate.toLocaleString(); return dateStringOutput; }; }

  • How to convert a string to variable name

    - by p1xelarchitect
    I'm loading several external JSON files and want to check if they have been successfully cached before the the next screen is displayed. My strategy is to check the name of the array to see if it an object. My code works perfectly when I check only a single array and hard code the array name into my function. My question is: how can i make this dynamic? not dynamic: (this works) $("document").ready(){ checkJSON("nav_items"); } function checkJSON(){ if(typeof nav_items == "object"){ // success... } } dynamic: (this doesn't work) $("document").ready(){ checkJSON("nav_items"); checkJSON("foo_items"); checkJSON("bar_items"); } function checkJSON(item){ if(typeof item == "object"){ // success... } } here is the a larger context of my code: var loadAttempts = 0; var reloadTimer = false; $("document").ready(){ checkJSON("nav_items"); } function checkJSON(item){ loadAttempts++; //if nav_items exists if(typeof nav_items == "object"){ //if a timer is running, kill it if(reloadTimer != false){ clearInterval(reloadTimer); reloadTimer = false; } console.log("found!!"); console.log(nav_items[1]); loadAttempts = 0; //reset // load next screen.... } //if nav_items does not yet exist, try 5 times, then give up! else { //set a timer if(reloadTimer == false){ reloadTimer = setInterval(function(){checkJSON(nav_items)},300); console.log(item + " not found.

Their code is something like: class function TStudent.FirstNameOf(aLastName: string): string; var i : integer; begin for i := 0 to Length(studentsArray) - 1 do begin if studentsArray[i].LastName = aLastName then begin result := studentsArray[i].FirstName; Exit; end; end; result := 'no match was found'; end; class function TStudent.LastNameOf(aFirstName: string): string; var i : integer; begin for i := 0 to Length(studentsArray) - 1 do begin if studentsArray[i].FirstName = aFirstName then begin result := studentsArray[i].LastName; Exit; end; end; result := 'no match was found'; end; My question is how can I avoid writing almost same code twice. Is there any way to pass the property as parameter of the functions.

  • Deleted array value still showing up on foreach loop in AS3 (bug in flash?)

    - by nexus
    It took me many hours to narrow down a problem in some code to this reproducible error, which seems to me like a bug in AVM2. Can anyone shed light on why this is occurring or how to fix it? When the value at index 1 is deleted and a value is subsequently set at index 0, the non-existent (undefined) value at index 1 will now show up in a foreach loop. I have only been able to produce this outcome with index 1 and 0 (not any other n and n-1). Run this code: package { import flash.display.Sprite; public class Main extends Sprite { public function Main():void { var bar : Array = new Array(6); out(bar); //proper behavior trace("bar[1] = 1", bar[1] = 1); out(bar); //proper behavior trace("delete bar[1]", delete bar[1]); out(bar); //proper behavior trace("bar[4] = 4", bar[4] = 4); out(bar); //for each loop will now iterate over the undefined position at index 1 trace("bar[0] = 0", bar[0] = 0); out(bar); trace("bar[3] = 3", bar[3] = 3); out(bar); } private function out(bar:Array):void { trace(bar); for each(var i : * in bar) { trace(i); } } } } It will give this output: ,,,,, bar[1] = 1 1 ,1,,,, 1 delete bar[1] true ,,,,, bar[4] = 4 4 ,,,,4, 4 bar[0] = 0 0 0,,,,4, 0 undefined 4 bar[3] = 3 3 0,,,3,4, 0 undefined 4 3

  • Java servlet's request parameter's name set to entire json object

    - by Geren White
    I'm sending a json object through ajax to a java servlet. The json object is key-value type with three keys that point to arrays and a key that points to a single string. I build it in javascript like this: var jsonObject = {"arrayOne": arrayOne, "arrayTwo": arrayTwo, "arrayThree": arrThree, "string": stringVar}; I then send it to a java servlet using ajax as follows: httpRequest.open('POST', url, true); httpRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); httpRequest.setRequestHeader("Connection", "close"); var jsonString = jsonObject.toJSONString(); httpRequest.send(jsonString); This will send the string to my servlet, but It isn't showing as I expect it to. The whole json string gets set to the name of one of my request's parameters. So in my servlet if I do request.getParameterNames(); It will return an enumeration with one of the table entries' key's to be the entire object contents. I may be mistaken, but my thought was that it should set each key to a different parameter name. So I should have 4 parameters, arrayOne, arrayTwo, arrayThree, and string. Am I doing something wrong or is my thinking off here? Any help is appreciated. Thanks

  • Refactoring two methods down to one

    - by bflemi3
    I have two methods that almost do the same thing. They get a List<XmlNode> based on state OR state and schoolType and then return a distinct, ordered IEnumerable<KeyValuePair<string,string>>. I know they can be refactored but I'm struggling to determine what type the parameter should be for the linq statement in the return of the method (the last line of each method). I thank you for your help in advance. private IEnumerable<KeyValuePair<string, string>> getAreaDropDownDataSource() { StateInfoXmlDocument stateInfoXmlDocument = new StateInfoXmlDocument(); string schoolTypeXmlPath = string.Format(STATE_AND_SCHOOL_TYPE_XML_PATH, StateOfInterest, ConnectionsLearningSchoolType); var schoolNodes = new List<XmlNode>(stateInfoXmlDocument.SelectNodes(schoolTypeXmlPath).Cast<XmlNode>()); return schoolNodes.Select(x => new KeyValuePair<string, string>(x.Attributes["idLocation"].Value, x.Value)).OrderBy(x => x.Key).Distinct(); } private IEnumerable<KeyValuePair<string, string>> getStateOfInterestDropDownDataSource() { StateInfoXmlDocument stateInfoXmlDocument = new StateInfoXmlDocument(); string schoolTypeXmlPath = string.Format(SCHOOL_TYPE_XML_PATH, ConnectionsLearningSchoolType); var schoolNodes = new List<XmlNode>(stateInfoXmlDocument.SelectNodes(schoolTypeXmlPath).Cast<XmlNode>()); return schoolNodes.Select(x => new KeyValuePair<string, string>(x.Attributes["stateCode"].Value, x.Attributes["stateName"].Value)).OrderBy(x => x.Key).Distinct(); }

  • Using LINQ, need help splitting a byte array on data received from Silverlight sockets

    - by gcadmes
    The message packats received contains multiple messages deliniated by a header=0xFD and a footer=0xFE // sample message packet with three // different size messages List<byte> receiveBuffer = new List<byte>(); receiveBuffer.AddRange(new byte[] { 0xFD, 1, 2, 0xFE, 0xFD, 1, 2, 3, 4, 5, 6, 7, 8, 0xFE, 0xFD, 33, 65, 25, 44, 0xFE}); // note: this sample code is without synchronization, // statements, error handling...etc. while (receiveBuffer.Count > 0) { var bytesInRange = receiveBuffer.TakeWhile(n => n != 0xFE); foreach (var n in bytesInRange) Console.WriteLine(n); // process message.. // 1) remove bytes read from receive buffer // 2) construct message object... // 3) etc... receiveBuffer.RemoveRange(0, bytesInRange.Count()); } As you can see, (including header/footer) the first message in this message packet contains 4 bytes, and the 2nd message contains 10 bytes,a and the 3rd message contains 6 bytes. In the while loop, I was expecting the TakeWhile to add the bytes that did not equal the footer part of the message. Note: Since I am removing the bytes after reading them, the header can always be expected to be at position '0'. I searched examples for splitting byte arrays, but non demonstrated splitting on arrays of unknown and fluctuating sizes. Any help will be greatly appreciated. thanks much!

  • Why ajax doesn't work unless I refresh or use location.href?

    - by Connor Tang
    I am working on a html project, which will eventually package by Phonegap. So I am trying to encode the data from html form to JSON format, then use ajax send to a php file resides on server, and receive the response to do something else. Now I use <a href='login.html'> in my index.html to open the login page. In my login page, I have this <script> $(document).ready(function(e) { $('#loginform').submit(function(){ var jData = { "email": $('#emailLogin').val(), "password": $('#Password').val()}; $.ajax({ url: 'PHP/login.php', type:'POST', data: jData, dataType: 'json', async: false, error: function(xhr,status){ //reload(); location.href='index.html'; alert('Wrong email and password'); }, success: function(data){ if(data[1] == 1){ var Id_user = data[0]; location.href='loginSuccess.html'; } } }); }); }); </script> to send my data to server. But I found that it won't work, it's still in the login page. I tried to enter data and submit again, it's still nothing happen. Until I refresh the login page and enter data again, it can give an error message or go to the loginsuccess page. However, when I use <script> function loadLogin(){ location.href='login.html'; } </script> to open the login page, everything works well. So what cause this? How can I modify this piece of code to make it better?
