  • jQuery UI Element vs Dojo (Dijit) Form Element

    - by Muers
    Dojo seems to have a useful feature in that it can setup event handlers and default options, etc for Dijit.form elements as it is inserting it into the DOM. For example, Dojo: var slider = new dijit.form.HorizontalSlider({ name: sliderContainerId+'_slider', value: sliderValue, minimum: sliderMax, maximum: sliderMin, onChange: function(value){ // some event handling logic } }, sliderContainerId); However, the jQuery UI Slider traditionally is applied to DOM elements that already exist: $( sliderContainerId ).slider({ value:100, min: 0, max: 500, step: 50, slide: function( event, ui ) { $( "#amount" ).val( "$" + ui.value ); } }); I need to be able to 'programmatically' create new Sliders (and other form elements), but I'm not sure how that could be achieved with the way jQuery is structured? Maybe I'm missing something obvious here.... MTIA

  • Returning JSON object from an ASP.NET page

    - by Emin
    Hi, In my particular situation, I have couple of solutions to my problem. I want to find out which one is more feasible. In this case, I can also achieve my goal by returning a JSON object from my server side code, however, I do not know how it is done and what is the best way of doing it. First off, I don't need a full aspx page as I only need a response returned from code. So, do I use web services? handler? or is there any other specific way you people do this? Is this solution feasible? do I build the JSON string using the StringBuilder class and inject that string into the target aspx page? are there any precautions? or things that I should be aware of? I appreciate your ideas. Regards, Kemal ------------UPDATE !------------ Suppose I have a JSON object in my userlist.aspx page. which then I use it with jQuery... {"menu": { "id": "color1", "value": "color", "popup": { "menuitem": [ {"value": "Red"}, {"value": "Green"}, {"value": "Yellow"} ] } }} // example taken from the json.org/example page now when I want to add a new menuitem from my aspx page, what do I do... I think this way my question is more specific... Lets assume I create a new string in my aspx code, as such "{"value": "Blue"}. Now how do I inject this into the already existing itemlist in the target page? or is this not the correct approach to this kind of situation? if not how else can it be achieved? Also if I wanted to fire a jquery event when a new item is added to this list, how is this achieved?

  • Objective-C Passing a variable to another IBAction

    - by StuR
    This works fine: NSString *myVariable; - (IBAction) doFirstAction { myVariable = @"123456789"; } - (IBAction) doSecondAction { NSLog(@"%@",myVariable); } However, if I do this (substituting the @"123456789" for some code which returns the same value ie "123456789") I cannot access the value in doSecondAction. NSString *myVariable; - (IBAction) doFirstAction { myVariable = [imageNode getAttributeName:@"value"]; } - (IBAction) doSecondAction { NSLog(@"%@",myVariable); } Any clue as to why I cant access myVariable outside of doFirstAction?

  • How can I use Linq to create an array of dictionaries from XML?

    - by Duke
    Given the following XML structure: <courses> <course> <title>foo</title> <description>bar</description> </course> ... </courses> How could I create an array of dictionaries such that each dictionary contains all the element/value pairs within a course? What I have right now generates an array whose elements contain a single key/value dictionary for each element/value pair in a course: XElement x = XElement.Parse("...xml string..."); var foo = (from n in x.Elements() select n) .Elements().ToDictionary(y => y.Name, y => y.Value); Produces: [0] => {[course, foo]} [1] => {[description, bar]} What I'd like is this: [0] => {[course, foo], [description, bar]}

  • Why is the Objective-C Boolean data type defined as a signed char?

    - by EddieCatflap
    Something that has piqued my interest is Objective-C's BOOL type definition. Why is it defined as a signed char (which could cause unexpected behaviour if a value greater than 1 byte in length is assigned to it) rather than as an int, as C does (much less margin for error: a zero value is false, a non-zero value is true)? The only reason I can think of is the Objective-C designers micro-optimising storage because the char will use less memory than the int. Please can someone enlighten me?

  • Magento layout related basic Questions ?

    - by user197992
    Here is what I think about Magento (plz correct me if I am wrong ) 1)Each module has its own layout.xml stored in /interface/theme/layouts/ folder. 2)Magento loads all these layouts for current theme and creates a big xml file. Now what I am confused at . a)If magento loads /default/default/ (interface & theme) then why all the templates & layouts are inside base/default/ ?? b)what if I create my module name “page” inside my namespace “Jason” i.e Jason_Page , now what will happen to blocks in layout files which are named c)Since all the layouts are loaded and merged into one big xml file , then what happen to all those reference blocks which have same name attribute and are inside “Default” handle tag ? e.g d)what is Local.xml layout for and its use ?? e)wats the relation ship between a module name foo , and its layout name foo.xml ? What will happen to layout.xml if two modules with same name exist in diff namespace ? Thanks in advance .

  • C# Type Casting at Runtimefor Array.SetValue

    - by sprocketonline
    I'm trying to create an array using reflection, and insert values into it. I'm trying to do this for many different types so would like a createAndFillArray function capable of this : Type t1 = typeof(A); Type t2 = typeof(B); double exampleA = 22.5; int exampleB = 43; Array arrA = createAndFillArray(t1, exampleA); Array arrB = createAndFillArray(t2, exampleB); private Array createAndFillArray(Type t, object val){ Array arr = Array.CreateInstance( t, 1); //length 1 in this example only, real-world is of variable length. arr.SetValue( val, 0 ); //this causes the following error: "System.InvalidCastException : Object cannot be stored in an array of this type." return arr; } with the class A being as follows: public class A{ public A(){} private double val; public double Value{ get{ return val; } set{ this.val = value; } } public static implicit operator A(double d){ A a = new A(); a.Value = d; return a; } } and class B being very similar, but with int: public class B{ public B(){} private double val; public double Value{ get{ return val; } set{ this.val = value; } } public static implicit operator B(double d){ B b = new B(); b.Value = d; return b; } } I hoped that the implicit operator would have ensured that the double be converted to class A, or the int to class B, and the error avoided; but this is obviously not so. The above is used in a custom deserialization class, which takes data from a custom data format and fills in the corresponding .Net object properties. I'm doing this via reflection and at runtime, so I think both are unavoidable. I'm targeting the C# 2.0 framework. I've dozens, if not hundreds, of classes similar to A and B, so would prefer to find a solution which improved on the createAndFillArray method rather than a solution which altered these classes.

  • persist values/variables from page to page

    - by Todd
    Hello, I'm wondering if there's another solution to my problem, that's considered more the Sharepoint way. FIrstly, my site is an Internet site, not Intranet. The problem is, all I'm trying to do is save values/variables from page to page in Sharepoint. I know the issue with Session Variables, but this seems to be the only way I can see to accomplish this. I know there are webparts that can store this value, but am I wrong in thinking this won't be persisted from page to page? Basically, I'll be extending the Content Query Web Part to dynamically filter it's results based off of a variable/value. The user chooses their 'area' from a dropdown, and the CQWP in the site will change and query results based off of this value (It will be a provincial structure as it is a Canadian site, so if someone chooses the province 'Ontario', this value is saved in a global variable, and these extended CQWP that are throughout the site, will get this value, and query lists flagged as Ontario). Is Session variables the only solution? Thanks everyone!

  • MySQL select one field from table WHERE condition is in multiple rows

    - by Alex
    Tried to find the answer, but still couldn't.. The table is as follows: id, keyword, value 1 display 15.6 1 harddrive 320 1 ram 3 So what i need is something like this.. Select an id from this table where (keyword="display" and value="15.6") AND (keyword="harddrive" and value="320") There's also a possibility that there will be 3 or 4 such keyword conditions which should result into returning one id (one row) It seems there's something to deal with UNION but i didn't use it before so i can't figure it out Thanks in advance

  • JQuery JEditable stay in edit mode on error

    - by Justin
    I'm successfully using jeditable to submit via a function using jQuery.ajax and the async : false option , but am having an issue aborting if an error is returned. How can I get the edit box to stay activated and / or revert back to the original value if there are errors? I'm returning http status codes. so something like async : false .ajax submit here... if (xhr.status == 200) { return value; else { alert ('returned error'); // keep edit box activated but available for another try, or revert back to original value } I tried not returning a value from the function, which keeps the edit box activated and ready for another submit, but then the ESC key doesn't work anymore and if I click outside the edit area, the edit box stays. Thanks in advance!

  • append versus resize for numpy array

    - by Abruzzo Forte e Gentile
    Hi all I would like to append a value at the end of my numpy.array. I saw numpy.append function but this performs an exact copy of the original array adding at last my new value. I would like to avoid copies since my arrays are big. I am using resize method and then set the last index available to the new value. Can you confirm that resize is the best way to append a value at the end? Is it not moving memory around someway? Thanks AFG oldSize = myArray,shape(0) myArray.resize( oldSize + 1 ) myArray[oldSize] = newValue

  • 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

  • jQuery - Form input return confirm to delete

    - by bruno
    hello guys. I struggled a lot before posting here :) now, I want to replace my default javascript confirmation for deleting a file. I saw a lot of examples here, but no example with form input. Now I have his form: <form action="delete.php" method="post"> <input type="hidden" name="id" value="<{$pid}>" /> <input type="hidden" name="picture" value="<{$lang_del_pic}>" /> <input type="image" src="<{xoImgUrl}>img/del-icon.gif" width="16" height="16" align="bottom" border="0" alt="Delete media" name="pictured" value="<{$lang_del_pic}>" onclick="javascript: return confirm('<{$lang_confirm_del}>');" /> </form> Now, I did everything, I have this div: <div id="dialog-confirm" title="Empty the recycle bin?"> <p><span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 20px 0;"></span>These items will be permanently deleted and cannot be recovered. Are you sure?</p> </div> this javascript: <script type="text/javascript"> $(document).ready(function() { $("#dialog").dialog({ autoOpen: false, modal: true }); }); $(".confirmLink").click(function(e) { e.preventDefault(); var targetUrl = $(this).attr("href"); $("#dialog").dialog({ buttons : { "Confirm" : function() { window.location.href = targetUrl; }, "Cancel" : function() { $(this).dialog("close"); } } }); $("#dialog").dialog("open"); }); </script> and this new form: <form name="dialog-confirm" id="dialog-confirm" method="post"> <input type="hidden" name="id" value="<{$pid}>" /> <input type="hidden" name="picture" value="<{$lang_del_pic}>" /> <input type="image" src="<{xoImgUrl}>img/del-icon.gif" width="16" height="16" align="bottom" border="0" alt="Delete media" name="pictured" value="" id="opener" /> </form> On press, I call successfuly the jQuery modal diolog, and everything works, but somehow, when I press 'delete all' the script tells me - "the script is called without the necessary parameters" Now I guess I am failig to send the pic ID to be deleted with the jQuery, .. but do not know how to fix it. Any ideas ?

  • Transient variables are not captured properly on form submission

    - by Kalpana
    My User entity class have several member variables (e.g. String firstName) which are persisted and some transient variables (e.g. transient boolean selected) which are not. I have used the transient variable to capture a checkbox selection, but invariably the value never gets set and procesed properly until I set another bean value along with it. i.e. If User has firstName (mapped to a text field) and selected (mapped to a checkbox) If I just selected the value doesn't seem to be set on an update If I had selected the checkbox and the firstName field, the "selected" value is captured properly Can anyone tell me why this is happening?

  • Is there programming language with better approach for switch's break statements ?

    - by Vitaly Polonetsky
    It's the same syntax in a way too many languages: switch (someValue) { case OPTION_ONE: case OPTION_LIKE_ONE: case OPTION_ONE_SIMILAR: doSomeStuff1(); break; // EXIT the switch case OPTION_TWO_WITH_PRE_ACTION: doPreActionStuff2(); // the default is to CONTINUE to next case case OPTION_TWO: doSomeStuff2(); break; // EXIT the switch case OPTION_THREE: doSomeStuff3(); break; // EXIT the switch } Now all you know that break statements are required, because the switch will continue to the next case when break statement is missing. We have an example of that with OPTION_LIKE_ONE, OPTION_ONE_SIMILAR and OPTION_TWO_WITH_PRE_ACTION. The problem is that we only need this "skip to next case" very very very rarely. And very often we put break at the end of case. It very easy for a beginner to forget about it. And one of my C teachers even explained it to us as if it was a bug in C language (don't want to talk about it :) I would like to ask if there are any other languages that I don't know of (or forgot about) that handle switch/case like this: switch (someValue) { case OPTION_ONE: continue; // CONTINUE to next case case OPTION_LIKE_ONE: continue; // CONTINUE to next case case OPTION_ONE_SIMILAR: doSomeStuff1(); // the default is to EXIT the switch case OPTION_TWO_WITH_PRE_ACTION: doPreActionStuff2(); continue; // CONTINUE to next case case OPTION_TWO: doSomeStuff2(); // the default is to EXIT the switch case OPTION_THREE: doSomeStuff3(); // the default is to EXIT the switch } The second question: is there any historical meaning to why it is like this in C? May be continue to next case was used far more often than we use it these days ?
