  • Javascript: regular expression

Please, see code below: var str = 'test ruby,ruby on rails,ruby,' var substr = 'ruby'; var reg = new RegExp(',' + substr + ',|^' + substr + ',', 'gi'); str.replace(reg, ','); //returns "test ruby,ruby on rails,"

  • jquery javascript error using $(...) selector

    - by waitinforatrain
    Hi, I'm migrating some old code to jquery: xmlHttp.onreadystatechange = function() { if (xmlHttp.readyState == 4) { $("#" + ajaxArea).html (xmlHttp.responseText); $("#" + ajaxArea).attr('title', 'Login'); $("#" + ajaxArea).dialog({ height : 140, modal : true }); } }; where ajaxArea is the ID of a DIV in the HTML. The dialog bit is basically adapted from the jQuery example here: http://jqueryui.com/demos/dialog/#modal All of it works fine up until the last line. Firefox throws an error that simply says "$(" for that line. Anyone know what might be causing this?

  • Trying to condense javascript into for loop

    - by rod
    I've got the following code that I am trying to condense to a for loop but am having no luck: $("#motion1-sub1-1").hover( function () { $("#motion1-sub1-1 div").show(); }, function () { $("#motion1-sub1-1 div").hide(); } ); $("#motion1-sub1-2").hover( function () { $("#motion1-sub1-2 div").show(); }, function () { $("#motion1-sub1-2 div").hide(); } ); $("#motion1-sub1-3").hover( function () { $("#motion1-sub1-3 div").show(); }, function () { $("#motion1-sub1-3 div").hide(); } ); $("#motion1-sub1-4").hover( function () { $("#motion1-sub1-4 div").show(); }, function () { $("#motion1-sub1-4 div").hide(); } ); $("#motion1-sub1-5").hover( function () { $("#motion1-sub1-5 div").show(); }, function () { $("#motion1-sub1-5 div").hide(); } ); Here's the for loop code that have to condense the above code: for (var i = 1; i <= 5; i++) { $("motion1-sub1-" + i).hover( function () { $("motion1-sub1-" + i + "div").show(); }, function () { $("motion1-sub1-" + i + "div").hide(); } ); }

  • getJSON and variable scope in javascript

    - by nillls
    Hi! In order to make function calls to our back-end php code we've implemented something called an ActionProxy like this: function ActionProxy(action, input, callback){ $.post("ActionProxy.php?method="+action, { data: input}, function(data, textStatus, XMLHttpRequest){ //return data.ResponseWhatever } }); The problem we're having is that using data outside the ActionProxy is impossible due to variable scope limitations (we assume), setting var res = data.ResponseWhatever or return data.ResponseWhatever is pretty futile. How would one handle these responses most appropriately so that functions calling the actionproxy can access the response values?

  • javascript pop-up menu help

    - by baiano
    I am working on a project similar to a table where the user will be able to add rows. Right now there is just one row type available but I would like to give the user the ability to select from a list without changing the layout of the page. So, I put together a menu that appears on mouseover of the 'add row' link and disappears on mouseout (with a slight delay and fade in/out) using mootools event listeners. It looks like: I am now trying to figure out an easy way to make it so that the list stays available when the user's mouse leaves the 'add a row' link to go to select an item from the list. I looked through various mootools add-ons and tutorial but didn't find anything all that helpful. Does anyone know of a good tutorial guide me through this or can otherwise point me in the right direction here?

    - by Luke101
    Here is the code I am working with: $(document).ready(function () { var TemplateEditor = function () { var GroupClassName = 'group'; var SelectedGroup = 0; var BindClicks = function () { $('.CriteriaSelections').unbind('click').click(function (event) { event.preventDefault(); if (fnIsTheClickedBoxaGroup($(this))) { TemplateEditor.GroupClicked(); } else { TemplateEditor.CriteriaClicked($(this), SelectedGroup); } }); $('.groupselected').unbind('click').click(function (event) { event.preventDefault(); SelectedGroup = $(this).attr('group-'.length); TemplateEditor.SelectGroup(SelectedGroup); }); } var fnGetGroupID = function (Obj) { if (fnIsTheClickedBoxaGroup(Obj) == true) { return null; } else { //Get parent which is the group var ObjParent = Obj.parent(); var GID = ObjParent.attr('id').substr('group-'.length); return GID; } } var fnIsTheClickedBoxaGroup = function (Obj) { var GetClass = Obj.attr('class'); if (GetClass == GroupClassName) { return true; } else { return false; } } return { Init: function () { BindClicks(); }, CriteriaClicked: function (Obj, GroupID) { $('<div>').attr({ id: '' }).addClass('selection').text(Obj).appendTo('#group-' + GroupID); }, GroupClicked: function () { }, SelectGroupClicked: function () { }, UpdateTargetPanel: function () { } }; } (); TemplateEditor.Init(); }); I am trying to access this variable: GroupClassName This variable is inside this function var fnIsTheClickedBoxaGroup = function (Obj) { var GetClass = Obj.attr('class'); if (GetClass == GroupClassName) { return true; } else { return false; } } When I run the program it says GroupClassName is undefined. Am I missing something here?

  • Javascript text Resize

    - by blackessej

  • Javascript How do I force a string + variable to be evaluated as a variable

    - by Craig Rinde
    Im not even sure how to word this and is probably why I am having trouble finding an answer in google. When the code is run currentCardRow will equal 1 therefore it should be cardSelected1 which is what is shown in the console.log. I need it to go a step further because cardSelected1 is a variable and I need it to evaluate show in the console log as Invitation. Invitation is an example of a variable for cardSelected1. I am not sure on what the correct syntax is to make this happen. var currentCardSelected = "cardSelected" + currentCardRow; Thanks for your help!

  • Javascript object encapsulation that tracks changes

    - by Raynos
    Is it possible to create an object container where changes can be tracked Said object is a complex nested object of data. (compliant with JSON). The wrapper allows you to get the object, and save changes, without specifically stating what the changes are Does there exist a design pattern for this kind of encapsulation Deep cloning is not an option since I'm trying to write a wrapper like this to avoid doing just that. The solution of serialization should only be considered if there are no other solutions. An example of use would be var foo = state.get(); // change state state.update(); // or state.save(); client.tell(state.recentChange()); A jsfiddle snippet might help : http://jsfiddle.net/Raynos/kzKEp/ It seems like implementing an internal hash to keep track of changes is the best option. [Edit] To clarify this is actaully done on node.js on the server. The only thing that changes is that the solution can be specific to the V8 implementation.

  • javascript location.hash refreshing in IE

    - by aepheus
    I need to modify the hash, remove it after certain processing takes place so that if the user refreshes they do not cause the process to run again. This works fine in FF, but it seems that IE is reloading every time I try to change the hash. I think it is related to other things that are loading on the page, though I am not certain. I have an iframe that loads (related to the process) as well as some scripts that are still being fetched in the parent window. I can't seem to figure out a good way to change the hash after all the loading completes. And, at the same time am not even positive that it is related to the loading. Any ideas on how to solve this?

  • Javascript: move the "view point" of the browser

    - by ArchJ
    I have a page with many out-of-bounds contents and since I set body{overflow:hidden}, they are not outside the viewport. So I want to attach a function to a button which would move the PoV of the browser so that the out-of-bounds contents would come into the viewport. What I can think of now is to set body{position:relative} and use jQuery to animate() the body instead. But in terms of performance, is there a better way to achieve that?
