  • Dependent checkbox, do you think this can be simplified more?

    - by Louie Miranda
    I have the following code which is working, I was wondering if this can simplified more. Demo: http://jsfiddle.net/TnpNV/8/ <form name="cbform"> <input type="checkbox" value="1" name="one" id="one" /> one<br /> <input type="checkbox" value="1" name="two" id="two" /> two </form>? <script> $('#one, #two').click(function(event) { var checked = $(this).is(':checked'); if (checked) { $('#one').attr('checked', true); $('#two').attr('checked', true); } else { $('#one').attr('checked', false); $('#two').attr('checked', false); } }); </script> It's basically a two checkbox that is dependent on each other. Jquery was used to check and uncheck them. Regards

  • Constant in Hibernate Mapping Files

    - by bertolami
    I would like to add a value object to a mapped class where one column is fixed depending of the class that contains the component. How can I do something like this? <component name="aComponent"> <property name="abc" column="cde"/> <property name="xyz" value="FIXED"/> </component> Unfortunatly, the value attribute does not exist. Is there another way to apply a constant value to property? Thanks in advance.

  • Context dependent validation

    - by Ole Lynge
    I would like to be able to validate an object in different contexts using DataAnnotations in .NET 4. For example: If I have a class with these annotated properties [Required] public string Name { get; set; } [Required] public string PhoneNumber { get; set; } [Required] public string Address { get; set; } I would like to be able to do something like bool namePhoneValid = Validator.TryValidateObject(entity, contextNamePhone, results1); bool allValid = Validator.TryValidateObject(entity, contextAll, results2); where contextNamePhone only validates Name and Phone, and contextAll validates all properties (Name, Phone and Address in this case). Is this possible? How should the validation context be constructed? Are there other/smarter ways to do this?

  • Handling hundreds of dependencies with ant

    - by Roberto
    Hi guys, I have to refactor an ant xml file. Basicly I have one big task that checkouts (using cvs) a lot of dependencies, build them, and then copy all the jar/wsdl generated by building them to a directory that I specify. If one dependency version changes, I have to change the name in at least 3 places on the xml file (cvs checkout, build, copy). What I'd like to have is just a single place where I can specify my dependencies name, without having to search & replace the dependency name through the code. One of the problems is that the cvs project could be /path1/path2/project with tag=v12 but then the jars generated by the single project build could be several with different names, so it seems to be a bit complicated. Do you have any idea on how I can get this done?

  • Text input for multi-valued attribute

    - by Sean
    I need to create an input form that will allow a user to enter any number of values for a particular attribute. I've tried several approaches, all of which seem to have various levels of failure. The latest model bean looks something like: public class Product { private String name; private String[] tags; ...accessors... } The input fields look something like: <h:inputText id="name" value="#{product.name}"></h:inputText> <h:inputText id="tag0" value="#{product.tag[0]}"></h:inputText> My plan was to allow the user is to use javascript to add additional form fields as needed. This type of setup gives me a 'Target Unreachable' error. What am I missing? I am using JSF 1.1 on WebSphere 6.1

  • Fulltext and composite indexes and how they affect the query

    - by Brett
    Just say I had a query as below.. SELECT name,category,address,city,state FROM table WHERE MATCH(name,subcategory,category,tag1) AGAINST('education') AND city='Oakland' AND state='CA' LIMIT 0, 10; ..and I had a fulltext index as name,subcategory,category,tag1 and a composite index as city,state; is this good enough for this query? Just wondering if something extra is needed when mixing additional AND's when making use of the fulltext index with the MATCH/AGAINST. Edit: What I am trying to understand is, what happens with the additional columns that are within the query but are not indexed in the chosen index (the fulltext index), the above example being city and state. How does MySQL now find the matching rows for these since it can't use two indexes (or can it?) - so, basically, I'm trying to understand how MySQL goes about finding the data optimally for the columns NOT in the chosen fulltext index and if there is anything I can or should do to optimize the query.

  • Java equivalent for database schema changes like South for Django?

    - by gerdemb
    I've been working on a Django project using South to track and manage database schema changes. I'm starting a new Java project using Google Web Toolkit and wonder if there is an equivalent tool. For those who don't know, here's what South does: Automatically recognize changes to my Python database models (add/delete columns, tables etc.) Automatically create SQL statements to apply those changes to my database Track the applied schema migrations and apply them in order Allow data migrations using Python code. For example, splitting a name field into a first-name and last-name field using the Python split() function I haven't decided on my Java ORM yet, but Hibernate looks like the most popular. For me, the ability to easily make database schema changes will be an important factor.

  • Layout form fields horizontally

    - by Don
    I'm using Ext JS 2.3.0 and have a bunch of fields contained within a FieldSet I'd like to have them laid out side-by-side instead, ideally with the label on top of the field instead of to the left of it. The relevant code is: var kpiFilterCombo = new Ext.form.ComboBox({ name: 'kpi', store: this.dashboardInst.servicesModel.getAvailableKPIsStore() }); var kpiLower = new Ext.form.TextField({ fieldLabel: "Lower", name: 'lowerBound' }); var kpiUpper = new Ext.form.TextField({ fieldLabel: "Higher", name: 'upperBound' }); var kpiFilterFieldset = new Ext.form.FieldSet({ title: locale['label.kpi.condition'], checkboxToggle: true, collapsed: true, autoHeight:true, items : [ kpiLower, kpiFilterCombo, kpiUpper, ] });

  • PHP Value Object auto create

    - by JonoB
    Assume that I have a class value object defined in php, where each variable in the class is defined. Something like: class UserVO { public $id; public $name; } I now have a function in another class, which is expecting an array ($data). function save_user($data) { //run code to save the user } How do I tell php that the $data parameter should be typed as a UserVO? I could then have code completion to do something like: $something = $data->id; //typed as UserVO.id $else = $data->name; //typed as UserVO.name I'm guessing something like the following, but this obviously doesnt work $my_var = $data as new userVO();

  • Filter objects within two seconds of one another using SQLAlchemy

    - by Arrieta
    Hello: I have two tables with a column 'date'. One holds (name, date) and the other holds (date, p1, p2). Given a name, I want to use the date in table 1 to query p1 and p2 from table two; the match should happen if date in table one is within two seconds of date in table two. How can you accomplish this using SQLAlchemy? I've tried (unsuccessfully) to use the between operator and with a clause like: td = datetime.timedelta(seconds=2) q = session.query(table1, table2).filter(table1.name=='my_name').\ filter(between(table1.date, table2.date - td, table2.date + td)) Any thoughts?

  • Jquery counting elements by class what is the best way to implement this?

    - by 133794m3r
    Ok what i'm trying to do is to count all of the elements in the current page with the same class and then i'm going to use it to be added onto a name for a input form. Basically i'm allowing users to click on an and then by doing so add another one for more of the same type of items. But i can't think of a way to count all of these simply with jquery/javascript. I was going to then name the item as something like name="whatever(total+1)", if anyone has a simple way to do this i'd be extremely grateful as javascript isn't exactly my native tongue and stack overflow usually has a ton of great answers and a great community so i'm hoping my query will not go unheard.

  • How is this inupt tag linking to another page?

    - by Matt
    Response.Write("<div><input type='submit' name='submit' value='Update Cart' /></div>") Response.Write("<div><input type='submit' name='submit' value='Shop More' /></div>") Response.Write("<div><input type='submit' name='submit' value='Checkout' /></div>") that is some example code from my teacher, but he hasn't answered my email in a couple days so I need some help. When you click the Update Cart button it just updates the cart page it's on, but when you click the Shop More button it links to Shop.aspx a different page, and the Checkout links to another page as well. I can't figure out how it is linking just from that code, anybody have any insights?

  • Nesting queries in SQL

    - by ZAX
    The goal of my query is to return the country name and its head of state if it's headofstate has a name starting with A, and the capital of the country has greater than 100,000 people utilizing a nested query. Here is my query: SELECT country.name as country, (SELECT country.headofstate from country where country.headofstate like 'A%') from country, city where city.population > 100000; I've tried reversing it, placing it in the where clause etc. I don't get nested queries. I'm just getting errors back, like subquery returns more than one row and such. If someone could help me out with how to order it, and explain why it needs to be a certain way, that'd be great.

  • Is there a performance gain from defining routes in app.yaml versus one large mapping in a WSGIAppli

    - by jgeewax
    Scenario 1 This involves using one "gateway" route in app.yaml and then choosing the RequestHandler in the WSGIApplication. app.yaml - url: /.* script: main.py main.py from google.appengine.ext import webapp class Page1(webapp.RequestHandler): def get(self): self.response.out.write("Page 1") class Page2(webapp.RequestHandler): def get(self): self.response.out.write("Page 2") application = webapp.WSGIApplication([ ('/page1/', Page1), ('/page2/', Page2), ], debug=True) def main(): wsgiref.handlers.CGIHandler().run(application) if __name__ == '__main__': main() Scenario 2: This involves defining two routes in app.yaml and then two separate scripts for each (page1.py and page2.py). app.yaml - url: /page1/ script: page1.py - url: /page2/ script: page2.py page1.py from google.appengine.ext import webapp class Page1(webapp.RequestHandler): def get(self): self.response.out.write("Page 1") application = webapp.WSGIApplication([ ('/page1/', Page1), ], debug=True) def main(): wsgiref.handlers.CGIHandler().run(application) if __name__ == '__main__': main() page2.py from google.appengine.ext import webapp class Page2(webapp.RequestHandler): def get(self): self.response.out.write("Page 2") application = webapp.WSGIApplication([ ('/page2/', Page2), ], debug=True) def main(): wsgiref.handlers.CGIHandler().run(application) if __name__ == '__main__': main() Question What are the benefits and drawbacks of each pattern? Is one much faster than the other?

  • What is @namespace field in C# class?

    - by MainMa
    Hi, I'm browsing the source code of StyleCop, and I found a curious thing: /// <summary> /// The namespace that the rule is contained within. /// </summary> private string @namespace; // [...] internal Rule(string name, string @namespace, string checkId, string context, bool warning) : this(name, @namespace, checkId, context, warning, string.Empty, null, true, false) { Param.Ignore(name, @namespace, checkId, context, warning); } What is this thing? Is it just a simple field where at-sign is used to indicate that it is a field, and not a namespace keyword? If so, may at-sign be used for any reserved word (for example @dynamic, @using, etc.)?

  • Why this java application print "true"?

    - by user292084
    This is my first Class Hello.java public class Hello { String name = ""; } This is my second Class Test1.java public class Test1 { public static void main(String[] args) { Hello h = new Hello(); Test1 t = new Test1(); t.build(h); System.out.println((h.name)); } void build(Hello h){ h.name = "me"; } } When I run Test1.java, it prints "me". I think I understand, because of "reference transfer". This is my third Class Test2.java public class Test2 { public static void main(String[] args) { Hello h = null; Test2 t = new Test2(); t.build(h); System.out.println(((h == null))); } void build(Hello h){ h = new Hello(); } } When I run Test2.java, it prints "true", why ? Is it "reference transfer" no longer? I am confused.
