  • Prevent default on a click within a JQuery tabs in Google Chrome.

    - by Sydney
    I would like to prevent the default behaviour of a click on a link. I tried the return false; also javascript:void(0); in the href attribute but it doesn’t seem to work. It works fine in Firefox, but not in Chrome and IE. I have a single tab that loads via AJAX the content which is a simple link. <script type="text/javascript"> $(function() { $("#tabs").tabs({ ajaxOptions: { error: function(xhr, status, index, anchor) { $(anchor.hash).html("Couldn't load this tab. We'll try to fix this as soon as possible. If this wouldn't be a demo."); }, success: function() { alert('hello'); $('#lk').click(function() { alert('Click Me'); return false; }); } }, load: function(event, ui) { $('a', ui.panel).click(function() { $(ui.panel).load(this.href); return false; }); } }); }); </script> <body> <div id="tabs"> <ul> <li><a href="linkChild.htm">Link</a></li> </ul> </div> </body> The content of linkChild.htm is <a href="javascript:void(0)" id="lk">Click Me</a> So basically when the tab content is loaded with success, a click event is attached to the link “lk”. When I click on the link, the alert is displayed but then link disappears. I check the HTML and the element is actually removed from the DOM.

How can i write the query to getting the price value is 0. Thanks in advance for help.

  • Syntax error converting the nvarchar value to a column of data type int.

    - by Phil
    I have 1,2,3,4,5,6,7,8,9 stored as nvarchar inside Level in my db. I then have a dropdownlist with values 1,2,3,4,5,6,7,8,9. When a user makes a selection (i.e 1) (Level.SelectedValue.ToString). This builds an sql query via a param like this: "Select things From MBA_EOI Where level = 1" When I run the select I get the following error: Syntax error converting the nvarchar value '1,2,3,4,5,6,7,8,9' to a column of data type int. I was under the impression that I was dealing with an Nvarchar field and the selected value as string, where does the int conversion come in? p.s I have also tried Level.SelectedItem.ToString

  • How do I test if a property exists on a object before reading its value?

    - by Jeremy Rudd
    I'm attempting to read a property on a series of Sprites. This property may or may not be present on these objects, and may not even be declared, worse than being null. My code is: if (child["readable"] == true){ // this Sprite is activated for reading } And so Flash shows me: Error #1069: Property selectable not found on flash.display.Sprite and there is no default value. Is there a way to test if a property exists before reading its value? Something like: if (child.isProperty("readable") && child["readable"] == true){ // this Sprite is activated for reading }

  • can I auto update my uitextview from the value of the row of my uipickerview without pressing any se

    - by Wesley
    So I have a uipicker view, that I have managed to load some data from my db into. I would like to update a textview, which is right above the pickerview, with each changing of the row. Is that possible? If I don't have to, I would like to avoid pushing a button in order to show the respective text. Can I make it so that the value in the text field changes with the value of the rowselected in the pickerview, in real time? Any thoughts or code snippets would be appreciated. Thanks!

  • List of fonts installed by default in versions of Windows?

    - by Ricket
    I've been seeing more and more websites using fancy antialiased fonts. Every time I hit one, I think to myself "hmm, what web-safe font is that?" - but after looking at the CSS I typically find some font name in quotes, like "Palatino Linotype". Obviously not web-safe, but according to the Wikipedia article, "Palatino Linotype is shipped with Windows 2000 or later, and Microsoft Office Professional Edition 2003." So that covers what, 95% of users that might visit your website? And thanks to the power of CSS, the website can fallback to a similar generic font typename such as 'serif' for non-Windows users with a line like this: font: 16px/20px "Palatino Linotype", serif; Awesome! I want to start using fancy fonts! Is there a set of lists out there, of the fonts that are preinstalled by default in Windows 98, 2000, NT, ME, XP, 2003, etc., and maybe for the Mac OSX versions and various Linux distributions as well? It would be a great reference for picking web font faces! (if not, someone should compile it!) I had never before heard of Palatino Linotype and I want to know what other fonts have existed since old Windows versions that I've never known about!

  • Why wouldn't the default Control Adapter mappings work on Chrome or Safari?

    - by Deane
    I have confirmed that my Control Adapters are not triggering in Chrome and Safari. I've debugged, and the breakpoints inside the adapters just don't get hit in Chrome/Safari, when they work perfectly find in Firefox/IE. So, for Chrome/Safari, IIS is just ignoring the mapping. My AdapterMappings.browser file looks like this: <browsers> <browser refID="Default"> <controlAdapters> [...adapters here....] </controlAdapters> </browser> </browsers> This should provide mappings for all browsers, correct? I used the Charles proxy to check what user agents were being sent. They are: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.1.249.1064 Safari/532.5 Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/531.22.7 (KHTML, like Gecko) Version/4.0.5 Safari/531.22.7 Any idea why this would be? Everything I've read tells me that my browser mappings are correct? And, as I said this works for IE/Firefox, so I know my configuration is technically correct.

  • Why can't I store a float value - it's always zero!

    - by just_another_coder
    I have a view controller that is created by the app delegate - it's the first one shown in the app. In its interface I declare float lengthOfTime; I also set it as a property: @property (nonatomic) float lengthOfTime; And in it's implemetation: @synthesize lengthOfTime; In the class viewDidLoad method, I set the value: self.lengthOfTime = 3.0f; However, after this, the value is always zero. No errors, no compile warnings, nothing. Just zero. The class is instantiated, it is showing in the view, so I'm pretty sure it's not a nil reference. I've searched all over Google and can't figure it out. What's going on?!? :(

  • Find HTML based on partial attribute

    - by Kirean
    Is there a way with javascript (particularly jQuery) to find an element based on a partial attribute name? I am not looking for any of the selectors that find partial attribute values as referenced in these links: starts with [name^="value"] contains prefix [name|="value"] contains [name*="value"] contains word [name~="value"] ends with [name$="value"] equals [name="value"] not equal [name!="value"] starts with [name^="value"] but more something along the lines of <div data-api-src="some value"></div> <div data-api-myattr="foobar"></div> and $("[^data-api]").doSomething() to find any element that has an attribute that starts with "data-api".

  • How do I select an item out of a JavaScript array when I only know a value for one of the item's pro

    - by minus4
    I have the following JavaScript object: { "DPI": "66.8213457076566", "width": "563.341067", "editable": "True", "pricecat": "6", "numpages": "2", "height": "400", "page": [{ "filename": "999_9_1.jpg", "line": [{ "test": "test 1", lineid: 22 }, { "test": "test 2", lineid: 22 }, { "test": "test 3", lineid: 22 }, { "test": "test 4", lineid: 22 }, { "test": "blank", lineid: 22 }] }, { "filename": "999_9_2.jpg", "line": [] }] } I can do most things with lines like measurements.page[0].line[0].lineid; But what I am really stuck with is when I want to edit a specific line but I only have the lineid value available (for example 22) and not the line number in the array: measurements.page[0].line[WHAT DO I PUT HERE].test = "new changed value";

  • How do I get query string value from script path?

    - by TruMan1
    I am adding my Javsacript file in pages with different query strings in the script path like this: Page1: <script type="text/javascript" src="file.js?abc=123"></script> Page2: <script type="text/javascript" src="file.js?abc=456"></script> Page3: <script type="text/javascript" src="file.js?abc=789"></script> In my Javascript file, how can I get the value of the "abc" param? I tried using window.location for this, but that does not work. In case it helps, below is a function I use to find the value of a query string param: function getQuerystring(key, defaultValue) { if (defaultValue == null) defaultValue = ""; key = key.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]"); var regex = new RegExp("[\\?&]" + key + "=([^&#]*)"); var qs = regex.exec(window.location.href); if (qs == null) return defaultValue; else return qs[1]; }

  • Adding objects to LDAP via CGI

    - by musashiXXX
    I have a web form that collects information and submits it to a cgi that attempts to insert the data into LDAP. The problem is that I'm trying to use a variable with ::ldap::add and it's just not working. Here's the code: if {[string length env(QUERY_STRING)] != 0} { set handle [::ldap::connect localhost] set dn "cn=admin,dc=mycompany,dc=com" set pw "myPassword" ::ldap::bind $handle $dn $pw set dn "cn=[ncgi::value givenName] [ncgi::value sn],ou=people,dc=mycompany,dc=com" set formValues [ puts "cn {{[ncgi::value givenName] [ncgi::value sn]}}" puts "displayName [ncgi::value givenName] [ncgi::value sn]" foreach {key value} [ncgi::nvlist] { if {[string length $value] != 0} { puts "$key $value" } } puts "objectClass top" puts "objectClass person" puts "objectClass organizationalPerson" puts "objectClass inetOrgPerson" ] ::ldap::add $handle $dn { $formValues } ldap::unbind $handle } However, if I replace $formValues with the actual entries that I want to insert into LDAP, they get added just fine. I'm new to TCL so I wouldn't be surprised if there were some glaring errors in this snippet. Thanks in advance!

  • C++ iterators, default initialization and what to use as an uninitialized sentinel.

    - by Hassan Syed
    The Context I have a custom template container class put together from a map and vector. The map resolves a string to an ordinal, and the vector resolves an ordinal (only an initial string to ordinal lookup is done, future references are to the vector) to the entry. The entries are modified intrusively to contain a a bool "assigned" and an iterator_type which is a const_iterator to the container class's map. My container class will use RCF's serialization code (which models boost::serialization) to serialize my container classes to nodes in a network. Serializing iterator's is not possible, or a can of worms, and I can easily regenerate them onces the vectors and maps are serialized on the remote site. The Question I need to default initialize, and be able to test that the iterator has not been assigned to (if it is assigned it is valid, if not it is invalid). Since map iterators are not invalidated upon operations performed on it (unless of course items are removed :D) am I to assume that map<x,y>::end() is a valid sentinel (regardless of the state of the map -- i.e., it could be empty) to initialize to ? I will always have access to the parent map, I'm just unsure wheather end() is the same as the map contents change. I don't want to use another level of indirection (--i.e., boost::optional) to achieve my goal, I'd rather forego compiler checks to correct logic, but it would be nice if I didn't need to. Misc This question exists, but most of its content seems non-sense. Assigning a NULL to an iterator is invalid according to g++ and clang++. This is another similar question, but it focuses on the common use-cases of iterators, which generally tends to be using the iterator to iterate, ofcourse in this use-case the state of the container isn't meant to change whilst iteration is going on.

  • Integer output in Java method not same as pre-converted char value.

    - by David
    I'm trying to parse a simple text file in an integer method and then output an integer from such file so that other parts of the program can use it. For testing purposes it also displays the character value (9 in this case). The integer value for some reason is 57. I've also tried it with another part of the text file (which in that case should be 5, but is instead 53). After looking at an ASCII chart, I see that 57 is the ASCII version of the "symbol" 9 and that 53 is the ASCII version of the "symbol" 5. Is there any simple way I can fix this? I'm getting kind of frustrated as I'm a Java newbie (I've mostly only used FreePascal before this).

  • How to best fetch a cell value from excel using VSTO?

    - by Behrooz Karjooravary
    I am trying to get cells from excel into csharp but not sure what's the best variable type to read it into. If I make the variable a string and the cell value is a double I get a parse error. If I make the variable double then when the cell is a string it wont work. Here's the code I am running: try { string i = Globals.Sheet1.Cells[7, 7].Value; double num; if (i == null) return; if (double.TryParse(i, out num)) { . . . } } catch (Exception e) { MessageBox.Show(e.ToString()); }

  • Possible to capture the returned value from a Python list comprehension for use a condition?

    - by Joe
    I want to construct a value in a list comprehension, but also filter on that value. For example: [expensive_function(x) for x in generator where expensive_function(x) < 5] I want to avoid calling expensive_function twice per iteration. The generator may return an infinite series, and list comprehensions aren't lazily evaluated. So this wouldn't work: [y in [expensive_function(x) for x in generator where expensive_function(x)] where y < 5] I could write this another way, but it feels right for a list comprehension and I'm sure this is a common usage pattern (possible or not!).

  • Are all of the default scripts loaded by Magento really needed?

    - by pxl
    Here's a listing of all the scripts loaded by Magento by default: ../js/prototype/prototype.js //prototype library ../js/prototype/validation.js //don't know what this does ../js/scriptaculous/builder.js //don't know what this does ../js/scriptaculous/effects.js //base scriptaculous effects library? ../js/scriptaculous/dragdrop.js //component of scriptaculous effects ../js/scriptaculous/controls.js //not sure? ../js/scriptaculous/slider.js //more scriptaculous effects ../js/varien/js.js //don't know what this is ../js/varien/form.js //form validation scripts? ../js/varien/menu.js //menu/drop down menu scripts ../js/mage/translate.js //don't know what this does ../js/mage/cookies.js //don't know what this does these scripts total 316.8K of javascript... all in various states of being minified (for example, prototype.js isn't minified). So my first question: 1) Aside from prototype.js, are all of the others really that needed? and 2) What is the "correct" way to remove these scripts? Layout updates? Or hardcoded in templates? I want to make the loading of my magento site as light weight as possible. thanks!

  • How to get the first non-null value in Java?

    - by froadie
    Is there a Java equivalent of SQL's COALESCE function? That is, is there any way to return the first non-null value of several variables? e.g. Double a = null; Double b = 4.4; Double c = null; I want to somehow have a statement that will return the first non-null value of a, b, and c - in this case, it would return b, or 4.4. (Something like the sql method - return COALESCE(a,b,c)). I know that I can do it explicitly with something like: return a != null ? a : (b != null ? b : c) But I wondered if there was any built-in, accepted function to accomplish this.

  • SQL decimal conversion error

    - by jakesankey
    Hey, my app parses numerous txt files in a directory that are almost all formatted identically, then inserts the values into columns of my sql db. However, there are a few files that the app has come across where a value is 'blank' instead of '0.0', so the application fails stating that it cannot convert that value to numeric. Is there a way I could change the following code to say what says AND also add 'IF value is blank, then import 0.0 instead? foreach (SqlParameter parameter in insertCommand.Parameters) { parameter.Value = null; } string[] values = line.Split(new[] { ',' }); for (int i = 0; i < values.Length - 1; i++) { // if (i = "" || i = null) continue; SqlParameter param = insertCommand.Parameters[i]; if (param.DbType == DbType.Decimal) { decimal value; param.Value = decimal.TryParse(values[i], out value) ? value : 0; } else { param.Value = values[i]; } }

  • WinForms - DateTimePicker default month selection behavior for Server 2003 vs Server 2008?

    - by Mike Loux
    Good Afternoon! Has anybody else noticed a change in the default behavior of the "next" and "previous" month arrows in the standard WinForms DateTimePicker control? I have users running on both Windows Server 2003 and Windows Server 2008 R2, and they are reporting that on 2008 (and Vista/Win7), clicking the right or left arrows on the drop-down Calendar now selects the first day of the month rather than retaining the same day like 2003 (and XP) does. I have checked this out (I have a Win7 machine) and I have confirmed this behavior. I would prefer that the behavior remain consistent whenever possible. Does anybody know what causes this and if there is a way to get around this? Is there a way to trap the arrow-click event and force the resulting date to retain the original day rather than be reset to the first of the month? I thought about seeing if there was a way to hit-test the control on a MouseUp event and determine if the arrow buttons were clicked, and then override the month value being set, but I'm not sure if that is even possible. Can anybody provide some wisdom or insight? Thanks!
