  • Jquery Dynamic fancy box

    - by MrThomas
    Loading fancybox from Jquery how can I retrieve the contents of a div ID on a page and not the whole page. This is my code so fare which gets me the whole page: $(function() { $(".style_image a").live('click', function(event) { $(".style_image a").fancybox(); return false; }); }); I have also tried the following with no success: $(function() { $(".style_image a").live('click', function(event) { $(".style_image a" + "#show_style").fancybox(); return false; }); }); I'm not sure how this is done as there is little info on the fancy box docs. I wish this to be done dynamically not inline.

  • Jquery forms plugin problem

    - by Dudul
    I have the following: $(document).ready(function(){ // bind 'myForm' and provide a simple callback function $('#form').ajaxForm(function() { alert("Works!!!"); }); }); The problem is that when I dynamically add the form to the HTML the script is not working. If the form is there from the beginning the form is submitted with Ajax and works as expected. What is the problem here?

    I have a controller insert action: <AcceptVerbs(HttpVerbs.Post)> _ Function InsertObject(<Bind(Exclude:="Id")> <ModelBinder(GetType(CustomModelBinder))> ByVal object As SomeObject) As ActionResult End Function And i have a CustomModelBinder class with a BindModel implementation: Public Function BindModel( _ ByVal controllerContext As System.Web.Mvc.ControllerContext, _ ByVal bindingContext As System.Web.Mvc.ModelBindingContext) As Object Implements System.Web.Mvc.IModelBinder.BindModel For Each s In HttpContext.Current.Request.Form.Keys HttpContext.Current.Response.Write(s & ": " & HttpContext.Current.Request.Form(s) & "<br />") Next HttpContext.Current.Response.End() End Function As you can see I have a controllerContext and a ModelBindingContext available.

  • Can functions like sin() be redefined, in Fortran, C or Java?

    - by EOL
    Can a mathematical function like sin() be redefined, in Fortran, C or Java code, while preserving the default behavior of other mathematical functions like cos()? Or can another function named sin() but that accepts different argument types be defined in addition to the built-in sin()? I am interested in general features of these languages (I am thinking of applications like the implementation of non-usual number algebras). I tried to define a sin() function in a Fortran 95 program, but the intrinsic sin() function was called instead… Is there a way around this? what about C and Java?

  • HTML form never calls Javascript

    - by user1205577
    I have a set of radio buttons defined in HTML like so: <input type="radio" name="group" id="rad1" value="rad1" onClick="doStuff(this.id)">Option 1<br> <input type="radio" name="group" id="rad2" value="rad2" onClick="doStuff(this.id)">Option 2<br> Just before the </body> tag, I have the following JavaScript behavior defined: <script type="text/javascript"> /*<![CDATA[*/ function doStuff(var id){ alert("Doing stuff!"); } /*]]>*/ </script> When I run the program, the page loads as expected in my browser window and the radio buttons allow me to click them. The doStuff() function, however, is never called (I validated this using breakpoints as well). I also tried the following just to see if inline made the difference, but it seems the JavaScript is never called at all: <script type="text/javascript"> /*<![CDATA[*/ alert("JavaScript called!"); main(); function main(){ var group = document.getElementsByName('group'); for(var i=0; i<group.length; i++){ group[i].onclick = function(){ doStuff(this.id); }; } } /*]]>*/ </script> My question is, is there something special I need to do using HTML and JavaScript in this context? My question is not whether I should be using inline function calls or whether this is your favorite way to write code.

  • HQL 'parsename' equivalent

    - by jaume
    I've discovered PARSENAME function as a good choice to order IP address stored in Database. Here there is an example. My issue is I'm using Hibernate with named queries in a xml mapping file and I am trying to avoid the use of session.createSQLQuery(..) function. I'm wondering if exists any PARSENAME equivalent function for HQL queries. I'm searching for it and cannot find anything. Many thanks.

  • PHPUnit test for error thrown with wrong argument type

    - by Spencer Mark
    I'm just starting with PHPUnit and am ok with all assert* methods, but can't figure out how to test for error thrown when the wrong argument is provided to the method - say hinted with array like so: public function(array $list) { } and then tested with null as argument. Could someone please provide an example of how to test for this sort of errors? I've checked quite a few posts on stackoverflow, but couldn't find the answer to this specific issue. Edit Ok - just to give you an idea of what I'm testing - here's the ArrayHelper::removeIfValueIsEmpty() method: public static function removeIfValueIsEmpty(array $array) { if (empty($array)) { return array(); } return array_filter($array, function($value) { return !Helper::isEmpty($value); }); } and now test: class ArrayHelperTest extends PHPUnit_Framework_TestCase { public function testRemoveIfValueIsEmpty() { $this->assertEmpty( \Cmd\Helper\ArrayHelper::removeIfValueIsEmpty(null), '\Cmd\Helper\ArrayHelper::removeIfValueIsEmpty method failed (checking with null as argument)' ); } } This throws an error: PHPUnit_Framework_Error : Argument 1 passed to Cmd\Helper\ArrayHelper::removeIfValueIsEmpty() must be of the type array, null given

  • Microsoft JScript runtime error Object doesn't support this property or method

    - by Darxval
    So i am trying to call this function in my javascript but it gives me the error of "Microsoft JScript runtime error Object doesn't support this property or method" and i cant figure out why. It is occuring when trying to call hmacObj.getHMAC. This is from the jsSHA website: http://jssha.sourceforge.net/ to use the hmac-sha1 algorithm encryption. Thank you! hmacObj = new jsSHA(signature_base_string,"HEX"); signature = hmacObj.getHMAC("hgkghk","HEX","SHA-1","HEX"); Above this i have copied the code from sha.js snippet: function jsSHA(srcString, inputFormat) { /* * Configurable variables. Defaults typically work */ jsSHA.charSize = 8; // Number of Bits Per character (8 for ASCII, 16 for Unicode) jsSHA.b64pad = ""; // base-64 pad character. "=" for strict RFC compliance jsSHA.hexCase = 0; // hex output format. 0 - lowercase; 1 - uppercase var sha1 = null; var sha224 = null; The function it is calling (inside of the jsSHA function) (snippet) this.getHMAC = function (key, inputFormat, variant, outputFormat) { var formatFunc = null; var keyToUse = null; var blockByteSize = null; var blockBitSize = null; var keyWithIPad = []; var keyWithOPad = []; var lastArrayIndex = null; var retVal = null; var keyBinLen = null; var hashBitSize = null; // Validate the output format selection switch (outputFormat) { case "HEX": formatFunc = binb2hex; break; case "B64": formatFunc = binb2b64; break; default: return "FORMAT NOT RECOGNIZED"; }

  • What is the best practice for including jQuery ext functions?

    - by Metropolis
    Hey everyone, Currently I have a file that I named JQuery.ext.js which I am including in all of my pages. Inside this file I have numerous functions that do things like the following, (function($) { /** * Checks to see is the value inside ele is blank * @param message string The message that needs to be displayed if the element is blank * @return bool */ $.fn.isEmpty = function(message) { var b_IsEmpty = false; //Loop through all elements this.each(function() { //Check to see if an empty value is found if($(this).val().length <= 0) { //If message is not blank if(message) { alert(message); $(this).focus().select(); } b_IsEmpty = true; return false; } return true; }); //Return false if the evaluation failed, otherwise return the jquery object so we can reuse it return (b_IsEmpty) ? true : false; }; /** * Checks to see if the value inside ele is numbers only * @param message string The message that needs to be displayed if the element is not numeric * @return bool */ $.fn.isNumeric = function(message) { var expression = /^[0-9]+$/; var b_IsNumeric = true; //Loop through elements checking each one this.each( function() { //Check to see if this value is not numeric if(!$(this).val().match(expression) && $(this).val().length > 0) { //If message is not blank if(message) { alert(message); $(this).focus().select(); } b_IsNumeric = false; } return b_IsNumeric; }); return b_IsNumeric; }; })(jQuery); Is there another way to do this? or is this the way most people do it? Thanks for any help, Metropolis

  • GUnload is null or undefined using Directions Service

    - by user1677756
    I'm getting an error using Google Maps API V3 that I don't understand. My initial map displays just fine, but when I try to get directions, I get the following two errors: Error: The value of the property 'GUnload' is null or undefined, not a Function object Error: Unable to get value of the property 'setDirections': object is null or undefined I'm not using GUnload anywhere, so I don't understand why I'm getting that error. As far as the second error is concerned, it's as if something is wrong with the Directions service. Here is my code: var directionsDisplay; var directionsService = new google.maps.DirectionsService(); var map; function initialize(address) { directionsDisplay = new google.maps.DirectionsRenderer(); var geocoder = new google.maps.Geocoder(); var latlng = new google.maps.LatLng(42.733963, -84.565501); var mapOptions = { center: latlng, zoom: 15, mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions); geocoder.geocode({ 'address': address }, function (results, status) { if (status == google.maps.GeocoderStatus.OK) { map.setCenter(results[0].geometry.location); var marker = new google.maps.Marker({ map: map, position: results[0].geometry.location }); } else { alert("Geocode was not successful for the following reason: " + status); } }); directionsDisplay.setMap(map); } function getDirections(start, end) { var request = { origin:start, destination:end, travelMode: google.maps.TravelMode.DRIVING }; directionsService.route(request, function(result, status) { if (status == google.maps.DirectionsStatus.OK) { directionsDisplay.setDirections(result); } else { alert("Directions cannot be displayed for the following reason: " + status); } }); } I'm not very savvy with javascript, so I could have made some sort of error there. I appreciate any help I can get.

Why is that? Is it because I can't send more than 1 request? openSend("time.php", "Time"); openSend("date1.php", "Date1"); If I can't, how could I achieve 3 requests with only one invocation?

  • Show iPad keyboard on select, focus or always (jQuery)

    - by Ryan
    I have a web app that is using jQuery to replace the RETURN key with TAB so that when I user presses return the form is not submitted but rather the cursor moves to the next text field. This works in all browsers but only 1/2 works on the iPad. On the iPad the next field is highlighted but the keyboard is hidden. How can I keep the keyboard visible or force it somehow? Here's my code (thanks to http://thinksimply.com/blog/jquery-enter-tab): function checkForEnter (event) { if (event.keyCode == 13) { currentBoxNumber = textboxes.index(this); if (textboxes[currentBoxNumber + 1] != null) { nextBox = textboxes[currentBoxNumber + 1] nextBox.focus(); nextBox.select(); event.preventDefault(); return false; } } } Drupal.behaviors.formFields = function(context) { $('input[type="text"]').focus(function() { $(this).removeClass("idleField").addClass("focusField"); }); $('input[type="text"]').blur(function() { $(this).removeClass("focusField").addClass("idleField"); }); // replaces the enter/return key function with tab textboxes = $("input.form-text"); if ($.browser.mozilla) { $(textboxes).keypress (checkForEnter); } else { $(textboxes).keydown (checkForEnter); } };

  • is it possible to write a program which prints its own source code utilizing a "sequence-generating-

    - by guest
    is it possible to write a program which prints its own source code utilizing a "sequence-generating-function"? what i call a sequence-generating-function is simply a function which returns a value out of a specific interval (i.e. printable ascii-charecters (32-126)). the point now is, that this generated sequence should be the programs own source-code. as you see, implementing a function which returns an arbitrary sequence is really trivial, but since the returned sequence must contain the implementation of the function itself it is a highly non-trivial task. this is how such a program (and its corresponding output) could look like #include <stdio.h> int fun(int x) { ins1; ins2; ins3; . . . return y; } int main(void) { int i; for ( i=0; i<size of the program; i++ ) { printf("%c", fun(i)); } return 0; } i personally think it is not possible, but since i don't know very much about the underlying matter i posted my thoughts here. i'm really looking forward to hear some opinions!

  • Facebook - generating fb tag in Jquery - not working

    - by Gublooo
    Hey guys Kind of stuck here - I have this functionality on my site where I display 10 user comments along with their photo and when a user clicks on "More" - using Jquery more results are fetched from DB and the results are displayed via string generated in the Jquery method. This is a shortened version of my Jquery function $(".more_swipes").live('click',function() { var profile_id = 'profile-user_id; ?'; $.getJSON("/profile/more-swipes", { user_id: profile_id},function(swipes) { $.each(swipes, function(i,data){ newcomment="<div"; newcomment +="<fb:profile-pic uid='"+data.fb_userid+"' linked='false'/"; newcomment +="Name="+data.user_name+"-Comment="+data.comment; $("#moreswipes").append(newcomment); }); }); return false; }); Here as you can see I'm using the tag <fb:profile-pic uid='"+data.fb_userid+"' linked='false'/ Now when more results get displayed, the profile pic of the user is not getting displayed - when I look at the source code - this is how the fb tag looks when its generated thru Jquery <fb:profile-pic uid="222222" linked="false" height="50" width="50" Whereas the FB tags not generated thru the Jquery code look like <fb:profile-pic uid="222222" linked="false" height="50" width="50" class="FB_profile_pic <fb_profile_pic_rendered FB_ElementReady" style="width:px;height:50px" <img src="http://profile.atk......2025.jpg" alt="User Name" title="User Name" style="width:px;height:50px" class="FB_profile_pic"/ </fb:profile-pic So when I add it as a String in JQuery function - facebook is not identifying it and executing it Any idea how to fix this Thanks a bunch

  • Dynamic upsert in postgresql

    I have this upsert function that allows me to modify the fill_rate column of a row.

Extra bonus points if there is a way to modify the function to take a column and a table.

  • Dynamic Select boxes page load

    Hello, I have a dynamic chained select box that I am attempting to show the value of on a page load. In my chained select box, it will default to the first option within the select box on page load, could anyone provide assitance? I stumbled upon this thread, but I can't seem to translate what they are doing with that answer to my language of CF. Dynamic chained drop downs on page refresh Here is the JS script I am using. function dynamicSelect(id1, id2) { // Feature test to see if there is enough W3C DOM support if (document.getElementById && document.getElementsByTagName) { // Obtain references to both select boxes var sel1 = document.getElementById(id1); var sel2 = document.getElementById(id2); // Clone the dynamic select box var clone = sel2.cloneNode(true); // Obtain references to all cloned options var clonedOptions = clone.getElementsByTagName("option"); // Onload init: call a generic function to display the related options in the dynamic select box refreshDynamicSelectOptions(sel1, sel2, clonedOptions); // Onchange of the main select box: call a generic function to display the related options in the dynamic select box sel1.onchange = function() { refreshDynamicSelectOptions(sel1, sel2, clonedOptions); } } } function refreshDynamicSelectOptions(sel1, sel2, clonedOptions) { // Delete all options of the dynamic select box while (sel2.options.length) { sel2.remove(0); } // Create regular expression objects for "select" and the value of the selected option of the main select box as class names var pattern1 = /( |^)(select)( |$)/; var pattern2 = new RegExp("( |^)(" + sel1.options[sel1.selectedIndex].value + ")( |$)"); // Iterate through all cloned options for (var i = 0; i < clonedOptions.length; i++) { // If the classname of a cloned option either equals "select" or equals the value of the selected option of the main select box if (clonedOptions[i].className.match(pattern1) || clonedOptions[i].className.match(pattern2)) { // Clone the option from the hidden option pool and append it to the dynamic select box sel2.appendChild(clonedOptions[i].cloneNode(true)); } } } Thanks so much for any assistance
