  • Global javascript variable not accessible in jquery change event

    - by Dan
    I have to be missing something simple, but I'm really not sure what. I'm not a JS veteran, so this may be an easy answer - sure hope so :). I have a button that, when clicked, gets JSON data. When a drop-down is changed, I check to see if there is data, if there is, I want to clear it out as the drop-down indicates what data to retrieve when the button is clicked The Code: var selected, $locDialog; var locations = []; $(function() { // Save the selected Name selected = $("#selected option:selected").val(); // Setup Dialog for Locations $locDialog = $('#location-dialog').dialog({ autoOpen: false }); // If user changes the selected // 1. Prompt for confirmation // 2. If users confirms, clear data $('#selected').change(function() { if (locations) { var confirmed = confirm("Oh Rly?"); if (confirmed) { // Clear data var locations; } } }); // When user clicks "Location" Button.. $('.loc-select button').click(function() { if (!locations) { $.getJSON("/Controller/JSONAction", { selectedId: selected, pageNum: 1, pageSize: 100 }, function(data) { locations = data; $.each(locations, function(index, loc) { var $tr = $('<tr/>') .append($('<td/>') .append('<input type="checkbox" name="TEST-'+index+'" value="'+loc.Id+'"/>')) .append('<td>' + loc.Name + '</td>'); $("#location-dialog table tbody").append($tr); }); }); } $locDialog.dialog('open'); return false; }); }); Here's the thing, Inside the .click(...) callback, I can see locations is []. Now, when I am in the .change(...) callback, I see locations is undefined. Any help/insight, as always, is appreciated!

  • jQuery: one-liner for removing all children but one

    - by user1352530
    HTML code is: <li> <a href="#" /> <ul> <li> <a href="#"/> </li> </ul> </li> I want to delete any node under $(this) = li that is not a link. If there are more than one link, just the first one is saved, and if there are links inside the ul tag, they are not included because they are descendants and no childrens. Something like this (I am cloning and outputting html): $(this).clone().remove('not(a:first)').html(); //Assuming remove looks for "a" as a first child Does not work, so I try with this: $(this).clone().children().remove('not(a:first)').parent().html(); Does not work so I try with this: $(this).clone().remove('not(>a:first)').html(); I need the original element as a reference after removal for chaining more operations EDIT: Ok! Second one works with a little syntax correction as some appointed (:not( instead of not() but I would like to know if there is any other solution similar to the third line so I don't have to do children().remove().parent(). Thank you!

  • jQuery arange li order base on #ID

    - by Mircea
    Hi, I have the following code: <ul> <li id="project_25">Proj Something</li> <li id="project_26">Proj Blah</li> <li id="project_27">Proj Else</li> <li id="project_31">Proj More</li> ... </ul> Is there a way to arrange these LIs, reverse their order, based on the LI ID? Something like: <ul> <li id="project_31">Proj More</li> <li id="project_27">Proj Else</li> <li id="project_26">Proj Blah</li> <li id="project_25">Proj Something</li> ... </ul> Thank you.

  • Parsing XML with jQuery

    - by Jamie
    I've used this: $(document).ready(function () { $.ajax({ type: "GET", url: "http://domain.com/languages.php", dataType: "xml", success: xmlParser }); }); function xmlParser(xml) { $('#load').fadeOut(); $(xml).find("result").each(function () { $(".main").append('' + $(this).find("language").text() + ''); $(".lang").fadeIn(1000); }); } I used a local XML file on my computer, it works fine, but when I change the URL to an website, it just keeps loading all the time... How do I get this to work?

  • New to javascript, why is jQuery such a beast?

    - by gnucom
    Hey Everyone, I'm new to javascript (functional programming is okay for me, though) and I am wondering how jQuery got away with some of the design decisions they made. Is it just too much work to fix now or what? For instance, there seems use of strange symbols in strings when accessing elements in the DOM or weird function definitions for $, that are forcing me to check references every other time I want to get some basic data. Can someone point me to a learning source where I can learn all of these nuances of jQuery (jQuery's examples just don't cut it, they're too spread out)? Maybe someone has a super good reference site/pdf for jQuery? Thanks

  • How do I make the "back button" work with jQuery hide/show functions?

    - by Walker
    I'm looking for a way to append text to the url with jQuery so that the back button is not broken when a user loads new content with jQuery. For example, I have a three step form - the first step is (www.xyz.com/form-1). When the user clicks next step, jQuery slides in the next page. I would like that page to be (www.xyz.com/form-2). I know websites like hypem.com do this, I'm just looking for an elegant way to handle it.

  • Not able to send POST request through jQuery Ajax

    - by Amit
    Hi, I was trying to send an ajax request as POST request. But when i verified it on httpFox on firefox, the request is sent as GET. I tried pbht $.ajax() and $.post(). Many had a query regarding the same and had missed the "type" in $.ajax(), but even if i mention the type as "POST", the request will be of type GET. Here is my code: $('.test').click(function(){ alert("clicked"); $.ajax({ type: "POST", url: "www.testsite.com", data: "name=John&location=Boston", success: function(msg){ alert( "Data Saved: " + msg ); } }); }); Any idea why it happens?

  • Stop setInterval within jQuery plugin

    - by Romelus
    I am trying to wrap up a plugin that I am writing but am stumped on a very trivial problem that I cant seem to find a solution for. I have tracked down almost every forum and related problem discussion. Any ways here is what I want to happen, my plugin has a timer that I would like the user to be able to handle its termination. (function ($) { ... var defaults = { callback : function(){}, crossfadeTime : 1000, easing : 'linear', running : 'true', // Here is where I would like the user to send a parameter // to invoke a different result. i.e. 'false' => clearing // the timer. Such as... var timer = setInterval(function(){ // Do Something; },3000); if(defaults.running == 'false'){ clearInterval(timer); }

  • jquery waiting until function is done

    - by matthewsteiner
    So, I set the closing function for simple modal as follows: $.modal.defaults.onClose = function (dialog) { $.validationEngine.closePrompt(".formError",true); dialog.data.fadeOut('slow', function () {}); dialog.container.fadeOut('slow', function () {}); dialog.overlay.fadeOut('slow', function () { $.modal.close(); }); } The line where the validationengine closes prompts basically just makes some divs disappear. The problem is that I don't want things to start fading out until closePrompt() is complete. Is there a way to do that? Is the only way with a "callback"? I don't think it has that built in to the function. Any other way to do it?

  • jquery .show("slide") options (WITH PICS!!)

    - by Micky Fokken
    Here's my code. It slides in from the left. <script> $('#goalHS').click(function() { $('div[id^="div-detailed-goal"]').show("slide"); }); $("#redline").click(function() { $('div[id^="div-detailed-goal"]').fadeOut("slow"); }); </script> Instead of fading in from the left, I want a red line to be drawn and then have the DIV slide in from the top. How can I get it to do the following? Horizontal red line grows out from center. --- Red line finishes growing: Content slides in from underneath red line. COntent does NOT show above red line: c. content, content, content d. content, content, content Content finishes sliding in. Awesomeness ensues! a. content, content, content b. content, content, content c. content, content, content d. content, content, content I've tried 4 different ways, and I've tried using other js plugin libraries, but I'm not quite that advanced to figure it out.

  • DOMAIN REDIRECT PROBLEM WITH JQUERY / JAVASCRIPT

    - by GiovanniDema
    Hi guys, first time here. I got a strange problem. I have a fullscreen image scaler javascript (as GOTOCHINA website) that works very well on my website. Then, I purchased a domain redirect pointing on my website and when redirecting suddenly internet explorer 7 and internet explorer 8 give me this error Messagge: is not a valid argument. Line: 34 Char: 17 URI: http://*****/scaler.js The script is var db=document.body; var imag=document.getElementById('wallpaper'); var dbsize={}; var imgsrc=imag.src; var keyStop=function(e){ var e=window.event||e||{}; var tag=e.target.tagName.toLowerCase(); if(tag!='textarea'&&!(tag=='input'&&(e.target.type=='text'||e.target.type=='password'))){ if(e.keyCode==32||e.keyCode==39||e.keyCode==40){ if(e.preventDefault)e.preventDefault(); else e.returnValue=false; } } } if(this.addEventListener)window.addEventListener('keydown',keyStop,false); else window.attachEvent('onkeydown',keyStop); setInterval(function(){ window.scrollTo(0,0); if(imag.complete){ if(db.clientWidth!=dbsize.w||db.clientHeight!=dbsize.h||imag.src!=imgsrc){ imgsrc=imag.src; var dbsizew=db.clientWidth; var dbsizeh=db.clientHeight; var newwidth=Math.round(dbsizeh*(imag.offsetWidth/imag.offsetHeight)); var nextvar=dbsizewnewwidth?dbsizew:newwidth; imag.style.width=nextvar+'px'; } } },300); In other words when i open the official website everything's working correctly. When i open redirect domain pointing on official website... the previous error appears. The line is exactly this - imag.style.width=nextvar+'px'; Thanks in advance Giovanni

  • jquery javascript module architecture on a website

    I want to write a module on one html site - I will never leave the site I think about two possible concurrent basic approaches: We go into the module by use only a specific function (with specific params - everything which will happen, happen there - logic, exception handling etc) We go in by using one handler-fct, which manages some kind of action & a dataArray (depending on the action also fcts will be called - but not directly maybe for exception handling) So what you prefer?!
