  • JQuery Validate: only takes the first addMethod?

    - by Neuquino
    Hi, I need to add multiple custom validations to one form. I have 2 definitions of addMethod. But it only takes the first one... here is the code. $(document).ready(function() { $.validator.addMethod("badSelectionB",function(){ var comboValues = []; for(var i=0;i<6;i++){ var id="comision_B_"+(i+1); var comboValue=document.getElementById(id).value; if($.inArray(comboValue,comboValues) != 0){ comboValues.push(comboValue); }else{ return false; } } return true; },"Seleccione una única prioridad por comisión."); $.validator.addMethod("badSelectionA",function(){ var comboValues = []; for(var i=0;i<6;i++){ var id="comision_A_"+(i+1); var comboValue=document.getElementById(id).value; if($.inArray(comboValue,comboValues) != 0){ comboValues.push(comboValue); }else{ return false; } } return true; },"Seleccione una única prioridad por comisión."); $("#inscripcionForm").validate( { rules : { nombre : "required", apellido : "required", dni : { required: true, digits: true, }, mail : { required : true, email : true, }, comision_A_6: { badSelectionA:true, }, comision_B_6: { badSelectionB: true, } }, messages : { nombre : "Ingrese su nombre.", apellido : "Ingrese su apellido.", dni : { required: "Ingrese su dni.", digits: "Ingrese solo números.", }, mail : { required : "Ingrese su correo electrónico.", email: "El correo electrónico ingresado no es válido." } }, }); }); Do you have any clue of what is happening?

  • jquery get last ID of dynamic div

    - by Pjack
    Couldn't find an answer, but Im trying to get the last ID of the last div that was created on the page. The code I'm using doesn't seem to work using .last(). My syntax is probably wrong but I can't get it to show the ID. jQuery(document).ready(function() {jQuery("a.more_posts").live('click', function(event){ jQuery("div[id^='statuscontainer_']").last(); var id = parseInt(this.id.replace("statuscontainer_", "")); alert(id); }); });

  • Detecting whether user stayed after prompting onBeforeUnload

    - by Daniel Magliola
    In a web app I'm working on, I'm capturing onBeforeUnload to ask the user whether he really wants to exit. Now, if he decides to stay, there are a number of things I'd like to do. What I'm trying to figure out is that he actually chose to stay. I can of course declare a SetTimeout for "x" seconds, and if that fires, then it would mean the user is still there (because we didn't get unloaded). The problem is that the user can take any time to decide whether to stay or not... I was first hoping that while the dialog was showing, SetTimeout calls would not fire, so I could set a timeout for a short time and it'd only fire if the user chose to stay. However, timeouts do fire while the dialog is shown, so that doesn't work. Another idea I tried is capturing mouseMoves on the window/document. While the dialog is shown, mouseMoves indeed don't fire, except for one weird exception that really applies to my case, so that won't work either. Can anyone think of other way to do this? Thanks! (In case you're curious, the reason capturing mouseMove doesn't work is that I have an IFrame in my page, containing a site from another domain. If at the time of unloading the page, the focus is within the IFrame, while the dialog shows, then I get the MouseMove event firing ONCE when the mouse moves from inside the IFrame to the outside (at least in Firefox). That's probably a bug, but still, it's very likely that'll happen in our case, so I can't use this method).

  • AJAX Beginner: If then statement

    - by dassouki
    In menu.html, I have my menu items(a href links), let's call them, menu_1, menu_2, .... In map.js displays the contents of a map, it calls an API to display some layers and maps. I have a lot of maps to show but i only want to call the api once. Using AJAX, I was wondering if it's possible to have an if/then or select/case in my js, so that if menu_1 is clicked, then implement map_1 etc. without having the page to reload. The only way I thought I could do this is using Post/get .. so when you click on menu_1 it takes you to page.php?page_id=1 . JS will read that and display the map. I'm new to JS and AJAX so please feel free to butcher me

  • Change the content type of a pop up window.

    - by Oscar Reyes
    This question brought a new one: I have a html page and I need it to change the content type when the user press "save" button so the browser prompt to save the file to disk I've been doing this in the server side to offer "excel" versions of the page ( which is basically a html table ) <c:if test="${page.asExcelAction}"> <% response.setContentType("application/vnd.ms-excel"); %> What I'm trying to do now is to do the same, but in the client side with javacript but I can't manage to do it so. This is what I've got so far: <html> <head> <script> function saveAs(){ var sMarkup = document.getElementById('content').innerHTML; //var oNewDoc = document.open('application/vnd.ms-excel'); var oNewDoc = document.open('text/html'); oNewDoc.write( sMarkup ); oNewDoc.close(); } </script> </head> <body> <div id='content'> <table> <tr> <td>Stack</td> <td>Overflow</td> </tr> </table> </div> <input type="button" value="Save as" onClick="saveAs()"/> </body> </html>

I need to call this function reloadPage like this from js file reloadPage({param1:'First Parameter', param2:ID}); but it gives me an error Line: 341 Error: Object doesn't support this property or method Line 341 is reloadPage({param1:'First Parameter', param2:ID});. What can I do to run this function from outside the directory? I tried parent.reloadPage({param1:'First Parameter', param2:ID}); But that didnt work either.

  • Using a variable as identifier in a json array

    - by Robbert van den Bogerd
    Hi folks! I'm wondering if it is possible to use assigned variables as identifier in a json array. When I tried this, I was getting some unexpected results: (Code is simplified, parameters are passed in a different way) var parameter = 'animal'; var value = 'pony'; Util.urlAppendParameters (url, {parameter : value}); Util.urlAppendParameters = function(url, parameters) { for (var x in parameters) { alert(x); } } Now the alert popup says: 'parameter' instead of 'animal'. I know I could use a different method (creating an array and assigning every parameter on a new line), but I want to keep my code compact. So my question is: Is it possible to use a variable as an identifier in the json array, and if so, could you please tell me how? Thanks in advance!

  • Can I fire a Text Changed Event for an asp.net Text Box before it loses focus?

    - by Xaisoft
    I have an asp.net TextBox in which I want to check if the text entered into the TextBox is > 0. It works once I tab out or click out of the TextBox, but if I keep focus on the TextBox, it won't fire the Text Changed Event, so I have the following scenario, I want to enable something if and only if the TextBox.Text.Length = 0. Now, if I put my caret in the TextBox and delete all the characters and then leave the caret in the TextBox so it still has focus and take my mouse and click a button, it will not do what it was supposed to do because it never fired the Text Changed Event. How would something like this be handled?

  • Calling methods within same Javwscript class [Prototype]

    - by eldeejay
    I've created a class in Javscript using the prototype Class.Create complete with the initialize function and a few other functions. However, in one of my functions I want to reference another function in the same class, but cannot seem to get the syntax correct. e.g. var sampleClass = Class.create({ initialize: function(){ //do the init work here }, functionA: function(){ //do some more stuff here } functionB: function(){ //Do some stuff functionA() } } I've tried calling functionA() , this.functionA() but nothing works I just get errors. I know how to call the functions externally when the class has been instantiated, but not reference a function from within the class itself. Thanks

  • Assigning console.log to another object (Safari issue)

    - by Trevor Burnham
    I wanted to keep my logging statements as short as possible while preventing console from being accessed when it doesn't exist; I came up with the following solution: var _ = {}; if (console) { _.log = console.debug; } else { _.log = function() { } } To me, this seems quite elegant, and it works great in Firefox 3.6 (including preserving the line numbers that make console.debug more useful than console.log). But it doesn't work in Safari 4. (Haven't tested in other browsers yet.) If I follow the above with console.debug('A') _.log('B'); the first statement works fine in both browsers, but the second generates a "TypeError: Type Error" in Safari. Is this just a difference between how Firebug and the Safari Web Developer Tools implement console? If so, it is VERY annoying on Apple's part. (I get the same results in both browsers if I bind the console function to a prototype and then instantiate, rather than binding it directly to the object.) I could, of course, just call console.debug from an anonymous function assigned to _.log, but then I'd lose my line numbers. Any other ideas?

  • Closing a Dialog Box, Opening a New One and it is Grayed out (Colorbox)

    - by Scott Faisal
    $.fn.colorbox({width:"40%", inline:true,href:"#somediv", opacity:"0.50",transition:"none", height:"490px"}); On #somediv above I have a button that once clicked executes the following code: line#45 $.fn.colorbox({href:"http://www.facebook.com", width:"65%",height:"80%",iframe:true}); I see facebook.com however the overlay is grayed out. I even tried using the following code instead of line#45 : $(document).one('cbox_closed', function(){ setTimeout(function(){ $.fn.colorbox({href:"http://www.facebook.com", width:"65%",height:"80%", iframe:true});},2); }); Now all I see is a blank overlay. Any suggestion guys?

If I test for $products inside the function it does show data... but once it finishes I can't seem to get the data. var $products = new Array(); connection.query($sql, function(err, rows, fields) { if (err) throw err; for(i=0; i< rows.length; i++) { $products[rows[i].source_identifier] = "xyz"; } }); connection.end(); console.log($products); // Shows empty.
