  • Unsure how to design JavaScript / jQuery functionality which uses XML to create HTML objects

    - by Jack Roscoe
    Hi, I'm using JavScript and jQuery to read an XML document and subsequently use the information from the XML to create HTML objects. The main 'C' nodes in the XML document all have a type attribute, and depending on the type I want to run a function which will create a new html object using the other attributes assigned to that particular 'C' node node. Currently, I have a for loop which extracts each 'C' node from the XML and also it's attributes (e.g. width, height, x, y). Also inside the for loop, I have an if statement which checks the 'type' attribute of the current 'C' node being processed, and depending on the type it will run a different function which will then create a new HTML object with the attributes which have been drawn from the XML. The problem is that there may be more than one 'C' node of the same type, so for example when I'm creating the function that will run when a 'C' node of 'type=1' is detected, I cannot use the 'var p = document.createElement('p')' because if a 'C' node of the same type comes up later in the loop it will clash and override that element with that variable that has just been created. I'm not really sure how to approach this? Here is my entire script. If you need me to elaborate on any parts please ask, I'm sure it's not written in the nicest possible way: var arrayIds = new Array(); $(document).ready(function(){ $.ajax({ type: "GET", url: "question.xml", dataType: "xml", success: function(xml) { $(xml).find("C").each(function(){ arrayIds.push($(this).attr('ID')); }); var svgTag = document.createElement('SVG'); // Create question type objects function ctyp3(x,y,width,height,baC) { alert('test'); var r = document.createElement('rect'); r.x = x; r.y = y; r.width = width; r.height = height; r.fillcolor = baC; svgTag.appendChild(r); } // Extract question data from XML var questions = []; for (j=0; j<arrayIds.length; j++) { $(xml).find("C[ID='" + arrayIds[j] + "']").each(function(){ // pass values questions[j] = { typ: $(this).attr('typ'), width: $(this).find("I").attr('wid'), height: $(this).find("I").attr('hei'), x: $(this).find("I").attr('x'), y: $(this).find("I").attr('x'), baC: $(this).find("I").attr('baC'), boC: $(this).find("I").attr('boC'), boW: $(this).find("I").attr('boW') } alert($(this).attr('typ')); if ($(this).attr('typ') == '3') { ctyp3(x,y,width,height,baC); // alert('pass'); } else { // Add here // alert('fail'); } }); } } }); });

  • JavaEE: Question about design

    - by Harry Pham
    I have a JSF page that will create a new Comment. I have the managed bean of that page to be RequestScoped managed bean. @ManagedBean(name="PostComment") @RequestScoped public class PostComment { private Comment comment = null; @ManagedProperty(value="#{A}") private A a; //A is a ViewScoped Bean @ManagedProperty(value="#{B}") private B b; //B is a ViewScoped Bean @PostConstruct public void init(){ comment = new Comment(); } // setters and getters for comment and all the managed property variable public void postComment(String location){ //persist the new comment ... if(location.equals("A")){ //update the comment list on page A }else if(location.equals("B")){ //update the comment list on page B } } } As you can see from the code above, 2 ViewScoped bean A and B will both use method postComment(), and getter getComment() from bean PostComment. The problem I am having right now is that, if I am on A, constructor of A will load, but it will also load constructor of bean B. This make my page load twice as slow. What would be the best way to solve this problem?

  • JPA entity design / cannot delete entity

    - by timaschew
    I though its simple what I want, but I cannot find any solution for my problem. I'm using playframework 1.2.3 and it's using Hibernate as JPA. So I think playframework has nothing to do with the problem. I have some classes (I omit the nonrelevant fields) public class User { ... } public class Task { public DataContainer dataContainer; } public class DataContainer { public Session session; public User user; } public class Session { ... } So I have association from Task to DataContainer and from DataContainer to Sesssion and the DataContainer belongs to a User. The DataContainers can have always the same User, but the Session have to be different for each instance. And the DataContainer of a Task have also to be different in each instance. A DataContainer can have a Sesesion or not (it's optinal). I use only unidirectional assoc. It should be sufficient. In other words: Every Task must has one DataContainer. Every DataContainer must has one/the same User and can have one Session. To create a DB schema I use JPA annotations: @Entity public class User extends Model { ... } @Entity public class Task extends Model { @OneToOne(optional = false, cascade = CascadeType.ALL) public DataContainer dataContainer; } @Entity public class DataContainer extends Model { @OneToOne(optional = true, cascade = CascadeType.ALL) public Session session; @ManyToOne(optional = false, cascade = CascadeType.ALL) public User user; } @Entity public class Session extends Model { ... } BTW: Model is a play class and provides the primary id as long type. When I create some for each entity a object and 'connect them', I mean the associations, it works fine. But when I try to delete a Session, I get a constraint violation exception, because a DataContainer still refers to the Session I want to delete. I want that the Session (field) of the DataContainer will be set to null respectively the foreign key (session_id) should be unset in the database. This will be okay, because its optional. I don't know, I think I have multiple problems. Am I using the right annotation @OneToOne ? I found on the internet some additional annotation and attributes: @JoinColumn and a mappedBy attribute for the inverse relationship. But I don't have it, because its not bidirectional. Or is a bidirectional assoc. essentially? Another try was to use @OnDelete(action = OnDeleteAction.CASCADE) the the contraint changed from NO ACTIONs when update or delete to: ADD CONSTRAINT fk4745c17e6a46a56 FOREIGN KEY (session_id) REFERENCES annotation_session (id) MATCH SIMPLE ON UPDATE NO ACTION ON DELETE CASCADE; But in this case, when I delete a session, the DataContainer and User is deleted. That's wrong for me. EDIT: I'm using postgresql 9, the jdbc stuff is included in play, my only db config is db=postgres://app:app@localhost:5432/app

  • Time until Members added to Group Policy is Replicated

    - by Kyle Brandt
    If I have a group policy, and add a group/user/machine etc to that group policy, how long is it until all domain controllers have that change in effect? This is a Windows 2003 Domain set up with controllers at different geographic locations (Each with a different L3 network). I realize it probably depends, but how do I figure out how long it generally takes for my given setup? Also, is there an event I can check to see if it has a reached a particular domain controller?

  • FTP upload stalls at same point every time on FileZilla

    - by John
    On two different FTP accounts, I am having problems uploading files. I can login and see the contents of the dir, and start an upload. Using Filezilla the transfer seems to always stall at either 0.9% or 1.2% (always those two numbers) and may simply hang, or keep restarting and then again stop at the same point. WindowsXP FTP is not great but I get similar types of problems there... it starts uploading and after a short while I get a timeout error. FTP used to work fine, and I don't know if it's these accounts in particular (both have the same service provider although purchased on opposite sides of the world) or if "FTP is broken on my PC"... can that even happen?!

    - by Nayn

  • How do I design this link table?

    - by Soo
    Ok SO, I have a user table and want to define groups of users together. The best solution I have for this is to create three database tables as follows: UserTable user_id user_name UserGroupLink group_id member_id GroupInfo group_id group_name This method keeps the member and group information separate. This is just my way of thinking. Is there a better way to do this? Also, what is a good naming convention for tables that link two other tables?

  • Design considerations for a multi-language web application

    - by gAMBOOKa
    I was asked by an interviewer today how I would implement Arabic as a second language into a PHP web application. I talked about choosing a unicode encoding for the database and the front-end, and designing RTL friendly user interface modules. And he didn't seem too happy with the answer. I don't really know anything about multi-lingual systems, how would you have answered that question?

  • Huge HDD response time in Resource monitor

    - by Mille
    Just bought all parts for a computer and put it together and installed a fresh version of windows 7. After a while, when using the computer it gets very slow, and even closing down windows can take several minutes. I started to look in the resource monitor and though I found the answer watching my hdd. The thing is that the hdd completes all tests in Seagate's SeaTools for Windows successfully. Which makes me doubt on the problem and weather I can send it in to get an replacement. Suggestions on what it could be and what I can do about it? Here a screenshoot from the resource monitor:

  • External stereo receiver and speakers on desktop PC work during test but no other time

    - by Debbie
    I have a desktop PC running Windows 7. I have connected an external stereo receiver and speakers to it and everything works fine when I test it in the Realtek Audio Sound through the control panel. However, when I play a video or an audio CD, the stereo speakers do not work. I have line in, line out, and speakers connected to the receiver. I have been through the configure speakers portion also. Is there someplace else I need to configure?

  • Creating a folder named after the current date and time

    I'm trying to create a powershell script that creates a new folder with the current date (formatted as yyyy-MM-dd) as a name. Here's what I have so far: PS C:\Users\me\Desktop> powershell.exe -command "new-item ($(get-location) + (Get-Date).year + "-" + (Get-Date).month + "-" + (Get-Date).day) -type directo ry" Die Benennung "C:\Users\me\Desktop" wurde nicht als Name eines Cmdlet, ein er Funktion, einer Skriptdatei oder eines ausführbaren Programms erkannt. Überp rüfen Sie die Schreibweise des Namens, oder ob der Pfad korrekt ist (sofern ent halten), und wiederholen Sie den Vorgang.

  • script to count the occurence of the particular string in the given time interval

    - by pruthvi
    We are trying to write a script "sendemail.sh" to count the number of occurrence of a particular string in a log file "SendEmail.log" within the given interval. We have a log file. In that we are searching for a pattern "ReqInputMsgLog" and need to count the number of times it occurred in the given period for eg: from "2014-08-19 11:30" to "2014-08-19 11:34". And our script look like this: #!/bin/sh enterdate=$1 echo $enterdate enddate=$2 enterdate1=`date +%s -d $enterdate +"%Y-%m-%d %H:%M"` echo $enterdate1 enddate1=`date +%s -d $enddate +"%Y-%m-%d %H:%M"` echo $enddate count=0 cat SendEmail.log | grep "ReqInputMsgLog" | awk -F "[" '{print $3}' | awk -F "," '{print $1}' > /con/scripts_server/file.txt for line in `cat /con/scripts_server/file.txt` do logdate=`echo $line | awk -F : '{print $1":"$2}'` if [[ $logdate < $enddate1 ]]; then count=`expr $count + 1` fi done echo $count But when we are trying to execute the script by the below command its not showing the proper count. ./sendemail.sh "2014-08-19 11:30" "2014-08-19 11:34" Log file is very big one. Small chunk has been posted here.

  • Looking for examples of good IDEs to analyze for Form/Report design

    - by Paul Sasik
    I am working on a basic form/report designer. Some of the features i'm looking to implement are: Single or multiple selection of objects Alignment of objects (when several are selected) Same-sizing of objects (when several are selected) Moving/dragging of selected object(s) Selected object resizing in eight directions (using object grips) For features and look-and-feel I've analyzed and used a mixture of ideas from: MS Visual Studio 200x (most useful so far) Visio Crystal Reports My question is: Have I overlooked some other IDEs that provide these kinds of features that are better and user-friendlier examples of what to do than others i've looked at? (They don't have to be Microsoft products. That's just what i have ready access to.)

  • Challenging question find if there is an element repeating himself n/k times

    - by gleb-pendler
    here how it's goes: You have an array size n and a constant k (whatever) you can assume the the array of int type tho it kind be of whatever type but just for the clearane let assume it's an integer. Describe an algorithm that finds if there is an element/s that repeat itself at least n/k times... if there is return one - do it in linear time running O(n) Imortent: now the catch do this algorithm or even pseuo-code using a constant usage of memory and running over the array only TWICE!!!

  • Choosing design method for ladder-like word game.

    - by owca
    I'm trying to build a simple application, with the finished program looking like this : I will also have to implement two different GUI layouts for this. Now I'm trying to figure out the best method to perform this task. My professor told me to introduce Element class with 4 states : - empty - invisible (used in GridLayout) - first letter - other letter I've thought about following solutions (by List I mean any sort of Collection) : 1. Element is a single letter, and each line is Element[]. Game class will be array of arrays Element[]. I guess that's the dumbest way, and the validation might be troublesome. 2. Like previously but Line is a List of Element. Game is an array of Lines. 3. Like previously but Game is a List of Lines. Which one should I choose ? Or maybe do you have better ideas ? What collection would be best if to use one ?
