  • clear input textbox value on load

    - by user544079
    I have the following form which is getting pre populated with values on load. I want to have empty input boxes on load using Javascript. However I do not have access to the <body> tag so <body onload="" will not work here. Is there any other way to clear the form fields on load? <form method="POST" action=""> <input name="username" id="user" value="" /><br /> <input name="pwd" id="pass" value="" /> <input type="submit" value="Go" /> </form>

  • What experience is the most valued in a programmer?

    - by Christo
    I've been coding application level software for a while now. I've had some experience with internet (server/client based) applications, but that has been fairly scant. The field doesn't scare although I know that experience can be almost be measured in gold. I see myself as a highly qualified and experienced programmer, but I also see my short comings in these fields. Does this count against me (and others like me?) and would this cut anyone from obtaining the shortlist or are there other factors which bear more weight?

  • SSRS 2005 Keep textbox and textfield together when page break occurs

    - by EKet
    Problem I don't have a details row or anything. I have simply a body and I dragged on textboxes for labeling textfields from my dataset. The problem is when one of the fields has too much data for the current page, it "page-breaks" at the start of the field leaving the textbox (label for the field) behind on the previous page. What I've tried Put the data field and the textbox label a) inside a rectangle - didn't work b) inside a list and the list inside a rectangle - didn't work c) inside a list with keep together property set to TRUE or FALSE - didn't work Question How would I group the textbox and the textfield so that regardless of where the pagebreak happens it includes its label?

  • Import orders file on magento enterprise 1.7 (product with customs options)

    - by wil
    Hello, We need to import some orders file on magento enterprise. In our file, products contains customs Options. We tried to make an extension but we have some problems to import Customs options. The import of standard product is successful but not for the product with customs options. For customs option, missing "info_buyRequest" valu in database. The technical support of magento we responded "the import process currently can't handle importing products with custom options". Magento use custom options when ordering a product with customs options on website. What features do magento use to fill in the fields "info_buyRequest" and "Product_options" when ordering? Have you see a extension pack for import file order with product contains customs options? Thanks for your help.

  • custom form with Drupal - CCK and simple module - what next?

    - by bert
    I have mastered creating custom data types and adding fields with CCK. Then I created and deployed a custom module with _form and _validate and _submit hooks. I am not happy with the amount of massaging required with css and permissions to make the form usable, but this is not my question. Now I would like to create a more sophisticated form with jquery to submit form and add content to page. I am at a bit of loss as how to get to this next level. I have been looking at tpl.php files, but this looks very rigid and more complicated as well. Can any provide a model or tutorial or point me in right direction.

  • Wrong intrepretation of some columns in ireport

    - by Purushotham
    Hi, I got a strange problem. I am using iReport 3.7.1 tool to create some reports. The Query Editor has one query. It shows all the data types of the fields in that query exactly same as the data types shown when I execute it using SQLYOG editor. The problem is here: One field data type is mismatched. I don't know the reason. SQLYOG says it is INTEGER whereas iReport Query Editor says its a long value. BTW The value that assigned to that filed is zero. Can anyone help ? I want to zero-in on this issue.

  • Java - JPA - @Version annotation

    - by Yatendra Goel
    I am new to JPA. I am cofused about the @Version annotation. How it works? I have googled it and found various answers whose extract is as follows: JPA uses a version field in your entities to detect concurrent modifications to the same datastore record. When the JPA runtime detects an attempt to concurrently modify the same record, it throws an exception to the transaction attempting to commit last. But still I am not sure how it works? ================================================================================== Also as from the following lines: You should consider version fields immutable. Changing the field value has undefined results. Does it mean that we should declare our version field as final

  • 600 tables in DDBB

    - by Michael
    Hi all, I'm a very young software architect. Now I'm working in a very large and I have to lead a group of developers to rewrite all the mortgage system of the bank. I'm looking at database tables and I realize that there is no any data model, neither documentation. The worst part is that there are about 1000 tables in dev environment, and like 600 in production. I trust more the production environment, but anyway, what can I do? I mean, I can suicide me or something, but is there any good reverse engineering tool, so at least I could get the schema definition with the relations between tables and comments extracted from the fields? Can you advice me something? Thanks in advance.

  • What is the best way to set default values in ActiveRecord?

    - by ryw
    What is the best way to set default value in ActiveRecord? I see a post from Pratik that describes an ugly, complicated chunk of code: http://m.onkey.org/2007/7/24/how-to-set-default-values-in-your-model class Item < ActiveRecord::Base def initialize_with_defaults(attrs = nil, &block) initialize_without_defaults(attrs) do setter = lambda { |key, value| self.send("#{key.to_s}=", value) unless !attrs.nil? && attrs.keys.map(&:to_s).include?(key.to_s) } setter.call('scheduler_type', 'hotseat') yield self if block_given? end end alias_method_chain :initialize, :defaults end YUCK! I have seen the following examples googling around: def initialize super self.status = ACTIVE unless self.status end and def after_initialize return unless new_record? self.status = ACTIVE end I've also seen people put it in their migration, but I'd rather see it defined in the model code. What's the best way to set default value for fields in ActiveRecord model?

  • How do I dynamically define an instance variable?

    - by Moses
    Hi everyone, I have two classes (class1 and class2) that just store data, no methods. I have a third class that has an instance variable that, depending on some user input, will be set to one of the two classes. So, in the third class I declare the variable generically as NSObject *aClass; and during runtime set it to whatever it should be. aClass = [[Class1 alloc] init]; // or aClass = [[Class2 alloc] init]; However, when I try to access fields from aClass NSString *str = aClass.field1; It gives me the error: request for member 'field1' in something not a structure or a union. Field1 is declared in both class1 and class2. When I try to cast aClass aClass = (Class1 *) aClass; it gives the same error. What am I doing wrong, is there a better way to do this?

  • MVC - Sanitizing data, where?

    - by dierre
    I'm using CakePHP but it's a question about the MVC pattern. I have in my form the input-text for the tags (separated by commas). To add the tags I've created a Tag model method that basically check if the tag exists and then add the new tag or just a new unit in the tag counter (the Tag model has these fields: id, name, slug, count). In the controller I explode the tags field and pass one tag at a time. The question is: where do I sanitize data? In the controller or in the model method? I think it should be in the controller because that's where I explode but in term of reusability I think I should sanitize data in the model. What do you think?

  • jQuery access each matched element from '.find' by an index

    - by GHarping
    Using jQuery's .find() method to return a set of elements, I am trying to access items in the returned set by their order in that set. For example, a table with two rows and in each row a select box and two text input fields, accessed with the following: $('table#tbl').find('tr.row').each(function(i) { }); To get the first element I would have thought I could use $('table#tbl').find('tr.row').each(function(i) { alert( $(this).find(':input').get(1).val() ); }); And variations of the above, but apparently this doesn't work. Could anyone suggest the correct method to access item x of n elements returned?

  • Using Linq to SQL change events with attribute-based mapping

    - by R Mene
    I'm writing a new ASP.NET MVC2 application using Linq to SQL. This application depends on an existing SQL database. I am using attribute-based mapping to map my database fields to my Linq to SQL entities. I also need to make use of Linq to SQL's On[Property]Changed methods so I can perform change-auditing of database tables within my application. Whereas the documentation explains how to do this when using Linq to SQL's ORM and dbml files (i.e. by writing partial classes), it is not clear how to do with when using attribute-based mapping or when using XML-based mapping. It would be very helpful if someone could describe how to do this.

  • How to display more things in admin.StackedInline

    - by FurtiveFelon
    Hi all, I have Article model and a Comment model. Comment is created in admin.py as admin.StackedInline, and it has several fields, notably content and lastUpdate. For lastUpdate, i have specified as follows: lastUpdate = models.DateTimeField('last update', auto_now=True). Understandably, lastUpdate is not displayed when i try to add new comment (or edit old ones). However, i would like it to display for older comments if possible, as a read only thing. Is there anyway of accomplishing that? Thanks a lot! Jason

  • Java - understanding servlets

    - by Trup
    I am working on a homework project that should implement a board game between 2 clients over an HttpServlet. I have couple of questions: 1) I read that HttpServlets must be stateless, however, for the sake of the game, I have to keep a lot of state(whose turn it is, the state of the board, etc). Do I have to keep this in the clients? Does the HttpServlet indeed have to be stateless, i.e. have no fields that track state? 2) I know that the clients will talk to the servlet via the doGet/doPost methods, but how can the servlet talk to the clients(for example, if player 1 just made a move and sent it to the servlet, the servlet has to tell client 2 what the move was). Thank you Also, if you can point me to a useful, simple example of a similar code online, I would be very grateful

  • Multithreading with STL container

    - by Steven
    I have an unordered map which stores a pointer of objects. I am not sure whether I am doing the correct thing to maintain the thread safety. typedef std::unordered_map<string, classA*>MAP1; MAP1 map1; pthread_mutex_lock(&mutexA) if(map1.find(id) != map1.end()) { pthread_mutex_unlock(&mutexA); //already exist, not adding items } else { classA* obj1 = new classA; map1[id] = obj1; obj1->obtainMutex(); //Should I create a mutex for each object so that I could obtain mutex when I am going to update fields for obj1? pthread_mutex_unlock(&mutexA); //release mutex for unordered_map so that other threads could access other object obj1->field1 = 1; performOperation(obj1); //takes some time obj1->releaseMutex(); //release mutex after updating obj1 }

  • How can I catch a change event from an HTML text field when a user clicks on a link after editing?

    - by Eric the Red
    Our webapp has a form with fields and values that change depending on values entered. Each time there is a change event on one of the form elements, we use an expensive AJAX call to update other elements on the page. This works great for selects, radio buttons and checkboxes. The issue comes in when a user adds content to a text field, and then clicks a link without taking the focus from the text field. The browser moves to a new page, and the contents of the text field are never saved. Is there an easy way to code around this? The AJAX call is too expensive to call with each key press. Here's an example of my Prototype code at the moment: $$('.productOption input.text').invoke('observe', 'change', saveChangeEvent);

  • ASP.NET/VB/SQL: trying to insert data, getting error "no value given for required parameters"

    I am pretty sure this is a basic syntax error, I am new at this and basically figuring things out by trial and error...

  • How to show raw_id value of a ManyToMany relation in the Django admin?

    - by luc
    Hello, I have an app using raw_id on both ForeignKeyField and ManyToManyField. The admin displays the value of the foreign key on the right of the edit box. Unfortunatey, it doesn't work with ManyToMany. I've checked the code and I think that it is the normal behavior. However I would like to know if someone has an easy tip to change this behavior? Thanks in advance Update: I've tried to subclass the ManyToManyRawIdWidget but I don't know how to say that the raw_id_fields should use my custom widget. formfield_overrides doesn't seem to work with raw_id fields

  • Controlling a browser from Python

    - by Noio
    I am looking for a way to control a browser from Python, i.e. fill out form fields and submit them, possibly call JS functions. I've looked around a bit, but as far as I could see PyWebKitGtk only lets you show the browser as a GUI element, not interface with it. Is there a way to do this easily? I wrote my program logic in Python, and I would hate to port it to JS. Besides that, even if I'd use pure JS "bookmarklets", those wouldn't be able to read/write to my local filesystem, would they? P.S. to quell your suspicions, I'm not trying to automatically fill out forum account creation forms or something similarly spammious, though the task is technically similar. I need to crawl/scrape sites for my research project.

  • Copy Paste is Disabled in Property Grid

    - by ofarooq
    Hi All, I have a FileNameEditor inside a property grid, which has a few entries like Main File : "C:\blah1" Sec File: "C:\blah2" and so on. My problem is that I cannot copy and paste from one property entry to another, and I cannot type in the fields manually as well. Is there a specific property that will enable editing inside the FileNameEditor. Example public class MyEditor : FileNameEditor { public override bool GetPaintValueSupported(ITypeDescriptorContext context) { return false; } public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value) { object e = base.EditValue(context, provider, value); if ((value as MyFileS) != null) { (value as MyFilesS).FileName = (String) e; } return e; } protected override void InitializeDialog(OpenFileDialog openFileDialog) { base.InitializeDialog(openFileDialog); } } Thanks

  • 'Recursive' LINQ calls

    - by Sir Psycho
    Hi, I'm trying to build an XML tree of some data with a parent child relationship, but in the same table. The two fields of importance are CompetitionID ParentCompetitionID Some data might be CompetitionID=1, ParentCompetitionID=null CompetitionID=2, ParentCompetitionID=1 CompetitionID=3, ParentCompetitionID=1 The broken query I have simply displays results in a flat format. Seeing that I'm working with XML, some sort of recursive functionality is required. I can do this using recursion, but would like to see the linq version. Any help appreciated. var results = from c1 in comps select new { c.CompetitionID, SubComps= from sc in comps.Where (c2 => c2.CompetitionID == c1.CompetitionID) select sc };
