  • jQuery .html not writing span on page load, rights the span on ajax response

    - by pedalpete
    I've got a bit of a calendar I'm building with events that go beyond the boundary of one day. I've got a graph which shows how many events are running concurrently. In order to graph out the events which go into another day, I look for hours24, and run an extra bit of code. jQuery('li#hour'+placeGroup+'_'+schedDay2+'_'+thisHour,nextDay).data('count', numStaff).html(''+printHour+''+numEvents+' scheduled').css('height',numEvents*5+'px'); The code is working, the li items are being found, proper height is the css is being applied, data is set, which I've checked by running alert(jQuery('li#hour'+placeGroup+'_'+schedDay2+'_'+thisHour,nextDay).data('count')); right after the pervious bit of code. The only thing that isn't being done is the .html(add span) stuff. I run this code in two places. Once when the page loads, and once when an action is taken which changes the number of events via an ajax response. The li DOM object I'm writting to is created before the script is run, and the height is being applied, but not the span, and only on page load. Any ideas on this one? I'm stumped.

  • Dynamic expression tree how to

    - by Savvas Sopiadis
    Hello everybody! Implemented a generic repository with several Methods. One of those is this: public IEnumerable<T> Find(Expression<Func<T, bool>> where) { return _objectSet.Where(where); } Given to be it is easy to call this like this: Expression<Func<Culture, bool>> whereClause = c => c.CultureId > 4 ; return cultureRepository.Find(whereClause).AsQueryable(); But now i see (realize) that this kind of quering is "limiting only to one criteria". What i would like to do is this: in the above example c is of type Culture. Culture has several properties like CultureId, Name, Displayname,... How would i express the following: CultureId 4 and Name.contains('de') and in another execution Name.contains('us') and Displayname.contains('ca') and .... Those queries should be created dynamically. I had a look in Expression trees (as i thought this to be a solution to my problem - btw i never used them before) but i cannot find anything which points to my requirement. How can this be costructed? Thanks in advance

  • Private member vector of vector dynamic memory allocation

    - by Geoffroy
    Hello, I'm new to C++ (I learned programming with Fortran), and I would like to allocate dynamically the memory for a multidimensional table. This table is a private member variable : class theclass{ public: void setdim(void); private: std::vector < std::vector <int> > thetable; } I would like to set the dimension of thetable with the function setdim(). void theclass::setdim(void){ this->thetable.assign(1000,std::vector <int> (2000)); } I have no problem compiling this program, but as I execute it, I've got a segmentation fault. The strange thing for me is that this piece (see under) of code does exactly what I want, except that it doesn't uses the private member variable of my class : std::vector < std::vector < int > > thetable; thetable.assign(1000,std::vector <int> (2000)); By the way, I have no trouble if thetable is a 1D vector. In theclass : std::vector < int > thetable; and if in setdim : this->thetable.assign(1000,2); So my question is : why is there such a difference with "assign" between thetable and this-thetable for a 2D vector? And how should I do to do what I want? Thank-you for your help, Best regards, -- Geoffroy

I do not really want to dispaly this button where the table is empty. So at least if the table is populated by nly one record i want that button being displayed. How should i deal in this case. Thanks.

  • Passing arguments and values from HTML to jQuery (events)

    - by Jaroslav Moravec
    What is the practice to pass arguments from HTML to jQuery events function. For example getting id of row from db: <tr class="jq_killMe" id="thisItemId-id"> ... </tr> and jQuery: $(".jq_killMe").click(function () { var tmp = $(this).attr('id).split("-"); var id = tmp[0] // ... } What's the best practise, if I want to pass more than one argument? Is it better not to use jQuery? For example: <tr onclick="killMe('id')"> ... </tr> I didn't find the answer on my question, I will be glad even for links. Thanks. Edit (pre solution) So you suggested two methods to do that: Add custom attributes to element (XHTML) Use attribute ID and parse it by regex Attribute data-* attributes in HTML5 Use hidden children elements I like first solution, but... I would like to (I have to (employer)) produce valid code. Here is a nice question and answers: http://stackoverflow.com/questions/994856/so-what-if-custom-html-attributes-arent-valid-xhtml And the second is not so pretty as the first, but valid. So the compromise is... The third is the solution for future, but here is a lot of CMS where we have to use XHTML or HTML4. (And HTML5 is the long process)

  • PHP Dynamic include based on current file path

    - by Adrian M.
    Hello, I want to find a method to include some files based on the current file path.. for example: I have "website.com/templates/name1/index.php", this "index.php should be a unique file that I will use in many different directories on different depths, so I want to make the code universal so I don't need to change anything inside this file.. So if this "index.php" is located in "website.com/templates/name1/index.php" than it should include the file located here: "website.com/content/templates/name1/content.php" another example: "website.com/templates/name2/index.php" than it should include the file located here: "website.com/content/templates/name2/content.php" Also I want to overrun "*Warning: include_once() [function.include-once]: http:// wrapper is disabled in the server configuration by allow_url_include=0*" kind of error.. because is disabled and unsafe.. Is there a way to achieve this? Thank you!

  • How to make the value of one select box drive the options of a second select box

    - by Ben McCormack
    I want to make an HTML form with 2 select boxes. The selected option in the first select box should drive the options in the second select box. I would like to solve this dynamically on the client (using javascript or jQuery) rather than having to submit data to the server. For example, let's say I have the following Menu Categories and Menu Items: Sandwiches Turkey Ham Bacon Sides Mac 'n Cheese Mashed Potatoes Drinks Coca Cola Sprite Sweetwater 420 I would have two select boxes, named Menu Category and Items, respectively. When the user selects Sandwiches in the Menu Category box, the options in the Items box will only show Sandwich options. I'm stuck as how I might approach this. Once I filter out the 2nd list one time, how do I "find" the list options once I change my menu category in the 1st list? Also, if I'm thinking in SQL, I would have a key in the 1st box that would be used to link to the data in the 2nd box. However, I can't see where I have room for a "key" element in the 2nd box. How could this problem be solved with a combination of jQuery or plain javascript?

  • Error implementing Dynamic Tab with ListView within each Tab - Tabs don't show up

    - by Jon
    I am trying to create a dyanmic tab application that has tabs on the left for each type of Food (e.g. Pasta, Dairy, etc. including those dynamically defined by user) and for each tab, have a listview connected to a SQLite database that updates. This is in the onCreate method: setContentView(R.layout.foodCabinet_layout); dbHelper = new FoodStorageDBHelper(this); dbHelper.open(); Cursor foodTypes = dbHelper.getAllFoodTypes(); ArrayList<String> typeOfFood = new ArrayList<String>(); typeOfFoods.add(foodTypes.getString(1)); while(foodTypes.moveToNext()){ typeOfFoods.add(foodTypes.getString(1)); } final TabHost tbh = (TabHost)findViewById(R.id.food_tabhost_cabinet); tbh.setup(); for(final String s : typeOfFood){ TabSpec nts = tbh.newTabSpec(s); nts.setIndicator(s.replace('_', ' ')); nts.setContent(new TabHost.TabContentFactory(){ public View createTabContent(String tag) { ListView foodCabinetLV = new ListView(FoodCabinet.this); Cursor mCursor = dbHelper.getAllFoodsWithType(s); // Create an array to specify the fields we want to display in the list (only TITLE) String[] from = new String[]{FoodStorageDBHelper.KEY_NAME, FoodStorageDBHelper.KEY_YEAR,FoodStorageDBHelper.KEY_RANK}; // and an array of the fields we want to bind those fields to (in this case just text1) int[] to = new int[]{R.id.childname,R.id.childyear,R.id.childrank}; // Now create a simple cursor adapter and set it to display SimpleCursorAdapter notes = new SimpleCursorAdapter(FoodCabinet.this, R.layout.food_row, mCursor, from, to); foodCabinetLV.setAdapter(notes); startManagingCursor(mCursor); foodCabinetLV.setOnItemClickListener( new AdapterView.OnItemClickListener() { public void onItemClick(AdapterView arg0, View arg1, int arg2, long arg3) { Intent i = new Intent(); i.setClass(arg0.getContext(), EditFoodDialog.class); i.putExtra(FoodStorageDBHelper.KEY_ROWID, Long.toString(arg3)); startActivityForResult(i, LoadFoodOrganizer.ACTIVITY_EDIT); } }); return foodCabinetLV; } }); } For some reason, it doesn't show anything... it's a blank screen. Any help would be very much appreciated. Let me know! Thanks! Jon

  • managing html rich text selections

    - by swami
    Hi, I am writing a component for a web app which will display some html, and let me capture and manipulate the selection boundaries (of the text selected by the user). I have done this successfully (for Mozilla) with a simple div element using window.getSelection(). However, the browser selection API is different for IE. If I were to use a textarea instead (for interacting with the selection api), is there a uniform API across the browsers? Then I would need to overlay a DIV on top of this to display the styled text, and presumably I'd need to manage the cursor etc... Basically I want a rich text editor - but without editing. Does anyone have any advice on the best way to go about this, which is quick, simple and cross browser compatible. I don't want to spend ages reinventing the wheel... (If anyone's interested - this is for an online xml editor. I capture the users selection on a html version of the xml doc and then send the selection offsets info to the server, where the real xml doc gets marked up). Kind Regards Swami

  • Dynamic classloading fails on runtime

    - by Henrik Paul
    I have the following snippet of java code: final Class<?> junitCoreClass = AccessController.doPrivileged( new PrivilegedAction<URLClassLoader>() { @Override public URLClassLoader run() { return new URLClassLoader(new URL[] { junitJarUrl }); } }).loadClass("org.junit.runner.JUnitCore"); System.out.println(junitCoreClass.getName()); final JUnitCore junitCore = (JUnitCore) junitCoreClass.newInstance(); This compiles fine. But when I try to run it, something weird happens; a java.lang.NoClassDefFoundError is thrown on that last line, referring to the class just loaded. The weird part is, the println prints the exact class name. I checked that if I keep the reference as an Object and manipulate it only through reflection, everything's fine, so the offending piece of code must be the explicit cast. Can someone explain to me why this happens, and also tell me how I can achieve what I'm trying to do?

  • html select execute javascript onload

    - by portoalet
    I am using HTML select onchange event to fire another javascript function func1. This html select is written into a form element, which are dynamically generated when users click on a button. The problem is how can I fire the javascript func1 when the dynamically generated form is first shown ? I am thinking of something along the line of on_first_show event for form ? Here is the snippet. I couldnt get the alert('don') to work either (the one just after div) var sPopupContents = "<div ><script type='text/javascript'>alert('don');</script> </div>"; // this javascript is not executed ? I cant get the alert. sPopupContents += "<form name='theform' >"; sPopupContents += "<select name='theselect' onchange='alert(2);"; sPopupContents += "func1()>'"; sPopupContents += "<option value='0' selected='selected'>Value1</option><option value='1'>Value2</option><br/>"; sPopupContents += "</form>";

  • Looking for a good Dynamic Imaging Solution

    - by user151289
    I work for a small E-Commerce shop and we are looking for a process that will handle resizing our product images dynamically. Currently our designers take high resolution photos, either provided by the manufactures or created in house, and alter them to fit various pages on our site. The designers are constantly resizing, cropping, altering compression levels, etc., of each product photo to fit the needs of the business. Being that our product line is updated frequently, this becomes a monotonous task. Abobe Scene7 does exactly what we are looking to do and the images are served up from a CDN. Unfortunately we found it to be too expensive. I'm curious to learn how others handle this process at their organizations. Does anyone know of any good 3rd party tools or other SAAS providers that can handle performing some basic image manipulation and serving them on the fly?

  • Inconsistent table width when hideing/showing a set of columns

    - by Salman A. Kagzi
    I have got a an HTML table of around 40+ columns. To make this table fit in the screen and have the data in a re presentable format we have section in this table. i.e. there are some column that are always visible and the remainder a made visible when s specific radio button (describing a section) is selected. Each radio button is associated to different number of columns. We show/hide a column by setting/removing "display:none" style in all the cell under that column. This all works Just fine. Now the real problem is with the width of the columns in this table. I cant use fixed with with pixel settings. I have tried using the percentage setting by giving 50% to the always visible part and rest 50% is divided between the column in a section. But I am unable to get a fixed behavior i.e. the size of the table columns across IE & FF. Some columns are just right while some are really huge. How can I get the table to give consistent column width across browsers?

  • Preserve HTML font-size when iPhone orientation changes from portrait to landscape

Right now, I have the hyperlink font size spec'ed to 14px, but when switching to landscape, it blows way up to like 20px. I want the font-size to stay the same.

  • Dynamic loading a class in java with a different package name

    - by C. Ross
    Is it possible to load a class in Java and 'fake' the package name/canonical name of a class? I tried doing this, the obvious way, but I get a "class name doesn't match" message in a ClassDefNotFoundException. The reason I'm doing this is I'm trying to load an API that was written in the default package so that I can use it directly without using reflection. The code will compile against the class in a folder structure representing the package and a package name import. ie: ./com/DefaultPackageClass.class // ... import com.DefaultPackageClass; import java.util.Vector; // ... My current code is as follows: public Class loadClass(String name) throws ClassNotFoundException { if(!CLASS_NAME.equals(name)) return super.loadClass(name); try { URL myUrl = new URL(fileUrl); URLConnection connection = myUrl.openConnection(); InputStream input = connection.getInputStream(); ByteArrayOutputStream buffer = new ByteArrayOutputStream(); int data = input.read(); while(data != -1){ buffer.write(data); data = input.read(); } input.close(); byte[] classData = buffer.toByteArray(); return defineClass(CLASS_NAME, classData, 0, classData.length); } catch (MalformedURLException e) { throw new UndeclaredThrowableException(e); } catch (IOException e) { throw new UndeclaredThrowableException(e); } }

  • Dynamic/Generic ViewModelBase?

    - by Shimmy
    I am learning MVVM now and I understand few things (more than but few are here..): Does every model potentially exposed (thru a VM) to the View is having a VM? For example, if I have a Contact and Address entity and each contact has an Addresses (many) property, does it mean I have to create a ContactViewModel and an AddressViewModel etc.? Do I have to redeclare all the properties of the Model again in the ViewModel (i.e. FirstName, LastName blah blah)? why not have a ViewModelBase and the ContactViewMode will be a subclass of ViewModelBase accessing the Entity's properties itself? and if this is a bad idea that the View has access to the entity (please explain why), then why not have the ViewModelBase be a DynamicObject (view the Dictionary example @ the link page), so I don't have to redeclare all the properties and validation over and over in the two tiers (M & VM) - because really, the View is anyway accessing the ViewModel's fields via reflection anyway. I think MVVM was the hardest technology I've ever learned. it doesn't have out-the-box support and there are to many frameworks and methods to achieve it, and in the other hand there is no arranged way to learn it (as MVC for instance), learning MVVM means browsing and surfing around trying to figure out what's better. Bottom line, what I mean by this section is please go and vote to MSFT to add MVVM support in the BCL and generators for VMs and Vs according to the Ms. Thanks
