  • How to avoid nested functions when using AJAX?

    - by Fletcher Moore
    Sequential Asynchronous calls are gross. Is there a more readable solution? The problem is this is hard to follow: ajaxOne(function() { // do something ajaxTwo(function() { // do something ajaxThree() }); }); where the anonymous functions are callbacks that are called on server response. I'm using a third party API to make the AJAX calls, so I need a generic solution.

  • Expression Expected

    I cannot figure out what I'm doing wrong syntactically here: function PlaceOrder(button) { var isValid; if (buttonIsSelected()) { showsMessage(btn, "showTestMessage2); isValid = true; } else { Page_ClientValidate(); if (Page_IsValid) { showMessage(btn, "testMessage"); isValid = true; } } return isValid; // error happens here }

  • Using Jquery to slowly hide a div

    - by Pete Herbert Penito
    Hi everyone! I'm trying to make some code which finds if a div exists, and if it does then have it fade away slowly. I have this to determine whether or not the div exists if($('#error').length != 0) { $('#error').hide(500); } And that does work but only on a refresh, I've been attempting to put it in a timer like this: var refreshId = setInterval(function() { if($('#error').length != 0) { $('#error').hide(500); } }, 500); But its not getting rid of the innerHTML! I have some code which on hover alters the innerHTML of the error div so I can fill it up, but for some reason this isn't working, any advice would help! Thank you!

  • Remove Attributes onmouseover and onmouseout

    - by Abs
    Hello all, I am trying to make use of JQuery's remove attribute like this: $('#rom-img_1').removeAttr('mouseover'); $('#rom-img_2').removeAttr('mouseout'); However, it does not remove the effects of the events as the events are still triggered on mouseover and on mouseout. I have tried adding "on" before the events names too but JQuery doesn't use it like that. Why isn't this working and how can I remove those attributes. This is a bit of the HTML: <div onmouseout="$('#heart_401').css({'display':'none'});" onmouseover="$('#heart_401').css({'display':'block'});" id="row-img_11"></div> Thanks all for any help

  • Display latest date from a HTML attribute

    - by Tron
    I currently have several classes which contain a date inside an attribute. <div id="container"> <div class="date" date="19/11/2013"></div> <div class="date" date="06/11/2013"></div> </div> <div id="result"></div> What I would like to do, is find the latest date and display it on the page. So far, I've found the information in the attribute, checked that it doesn't exist in the array then and pushed it into an array. I'm not entirely sure of the best approach from here, but ideally i would like to find the latest date and then append it to the results container. $('.date').each(function () { var dateArray = []; var date = $(this).attr('date'); if ($.inArray(date, dateArray) == -1) { dateArray.push(date); } $('#result').append(dateArray); }); Any assistance on the above would be greatly appreciated. Thanks :)

  • JQGrid: Dynamically set a cell to uneditable based on content

    - by Shawn
    I'm having some issues getting some cells (with cellEdit: true) to be non-editable even though the column is set to editable. I've tried many ways, like beforeEditCell, formatters, etc. None seem to work. The closest I've got is by setting a formatter to the column that I'd like to be editable and then using setCell to set the 'not-editable-cell' class (snippet below). The first time you click the cell, it unfortunately goes into edit mode, but if you click elsewhere and try to re-edit the cell, it's successfully uneditable. I've also tried using the same snipped but inside of beforeEditCell, it successfully stops the cell from being edited but in turn 'freezes' the grid. You can no longer select any other cell. function noEditFormatter(cellValue, options, rowObject) { if (cellValue == 'test') jQuery("#grid").jqGrid('setCell', options.rowId, 'ColName', '', 'not-editable-cell'); return cellValue; } Any help would be much appreciated.

  • Firefox can not layout nested tables properly?

    - by ooplidi
    I want to implement a collapsible menu. I plan to use table component to simulate a menu, and nest a sub table into a table cell to simulate a sub menu. Below is my code, it works as expected in IE, Chrome and Safari, but it doesn't work well in Firefox: <html> <body> <div id="menu" style="position:absolute; left:150px; top:100px; z-index:1"> <table width="200px" height="90" border=1 cellpadding="0" cellspacing="0"> <tr> <td colspan=2>Money</td> </tr> <tr> <td colspan=2>Tool</td> </tr> <tr> <td>Food <table style="position:absolute; left:200px; top:60px; z-index:1" width="200px" height="60px" border="1" cellpadding="0" cellspacing="0"> <tr> <td>Cookie</td> </tr> <tr> <td>Fruit <table style="position:absolute; left:200px; top:30px; z-index:1" width="200px" height="60px" border="1" cellpadding="0" cellspacing="0"> <tr> <td>Apple</td> </tr> <tr> <td>Banana</td> </tr> </table> </td> </tr> </table> </td> </tr> </table> </div> </body> </html> It seems that Firefox think the "left" and "top" attribute for the level 3 menu is relative to the level 1 menu, so it layout the level 3 menu incorrectly. Other browsers will calculate the offset base on the level 2 menu, that works as expected. Is it a bug in Firefox? If so how can I work around it? I want my code to have the same behavior in all major browsers.

  • Call overidden method in Dojo

    - by nomind
    In dojo, one cannot call a overidden superclass method outside of the same method in the derived class (for which there is this.inherited(), other than that one can call using class_name.function_name.apply). This feature is no longer there because of some refactoring and dojo guys are not going to put it back because they are not convinced about a good enough case for this. Please read this mail thread for details. Isn't there a good enough case for this functionality? Why or why not?

  • An image cropper: How to prevent the default drag n' drop action?

    - by David Gore
    I am developing an image cropper and would like to ask you the following question: In order to prevent the default drag n' drop action when you press the left button on an image and keeping it pressed try to move the mouse, wouldn't it be cross-browser if to just use the picture as a background to a div box? Just like so: <div id="theDiv" style="background:url(pic.png) no-repeat;"></div> How do you think? Is it acceptable? Not too ugly? Or should be done with JS?

  • How do I scope variables properly in jQuery?

    - by safetycopy
    I'm working on a jQuery plugin, but am having some trouble getting my variables properly scoped. Here's an example from my code: (function($) { $.fn.ksana = function(userOptions) { var o = $.extend({}, $.fn.ksana.defaultOptions, userOptions); return this.each(function() { alert(rotate()); // o is not defined }); }; function rotate() { return Math.round(o.negRot + (Math.random() * (o.posRot - o.negRot))); }; $.fn.ksana.defaultOptions = { negRot: -20, posRot: 20 }; })(jQuery); I'm trying to get the private function rotate to be able to see the o variable, but it just keeps alerting 'o is not defined'. I'm not sure what I'm doing wrong.

  • Ajax response takes time and status is 503

    - by Suresh S
    guys, i have a html page where onclick of a button a ajax request is sent to server , the request calls a jsp page which runs an oracle procedure.The procedure runs the logic and places it in a temp table . once procedure is completed , the values are returned to the client by selecting values from tmp table. as the response is too late . the data is not received at the client side. solution: i tried to run the procedure in a separate thread using a ajax call. when the procedure is completed a global flag is set to indicate that the data is generated. if the response is 500 , a second ajax call invoked by timeout function after 10000 ms . the second call checks the global flag ,if true then reads from table and sends the response. if not again a timeout is set at the client side. this solution is not mature enough. , as the procedure may take long time to respond. please let me know a good solution for this problenm?

  • Ajax, not sending querystring data

    - by Tom Gullen
    var http = false; // Creates xmlhttp object if (navigator.appName == "Microsoft Internet Explorer") { http = new ActiveXObject("Microsoft.XMLHTTP"); } else { http = new XMLHttpRequest(); } http.onreadystatechange = function() { if (http.readyState == 4) { alert(http.responseText); } } // Functions to calculate optimum layout etc. function compute() { var statusSpan = document.getElementById("cwStatus"); document.getElementById("fader").style.display = ""; document.getElementById("computingWait").style.display = ""; statusSpan.innerHTML = "<b>Status:</b> Realigning sattelites" http.open("GET", "alg.aspx?cr=8&cc=7&sq=3,3", true); http.send(null); } This code sort of works, but the querystring data isn't being passed through. It keeps returning an ASPX error page which only happens when there is no querystring data. Thanks for any help

  • AngularJS Bind Attribute Presence

    - by Chuck
    I want to bind the presence of an attribute to a variable in AngularJS. Specifically, sandbox for an iframe. Say I have $myCtrl.allowJavascript as a variable, I want to do: <iframe src="..." sandbox /> Where the sandbox attribute is present when allowJavascript == false, and I want the sandbox attribute to disappear when allowJavascript == true. Does AngularJS have a mechanism for this? The closest thing I could find was here, which basically says "it will just work for certain attributes"--but not for sandbox.

  • jQuery code works in Firebug, but not on its own

    - by Ben
    I'm having quite the brainbuster of an issue right now. I am trying to change a link's hash tag at the end from "respond" to "comments" with jQuery. I have a simple script that should do this, however it does not work. The link does not change. However, Firebug shows no errors and when I run the code in Firebug's console, it works just as I intend. Why doesn't this work on its own? Does anybody have a solution, I'm at my wits edge with this one. (function ($) { $(document).ready(function() { $("a[href$='respond']").each(function() { $(this).attr("href", $(this).attr('href').replace("respond", "comments")); }); }); })(jQuery.noConflict()); Thanks so much, I know this might be a pain to test but I'm really thankful.
