  • Gaining Reference to the Dialog from Dialog content

    - by coffeeaddict
    Here's my scenario: I've got a div on Page A. When an event happens (whatever I define, a click, whatever), I do a div.Dialog, set its properties and open it The data inside is returned from an async .ajax call that grabs the data from a url and appends it to the div by calling div.html(data) inside the .ajax callback, so it's essentially loading a PageB by getting the data (content) and appending it to the div that's calling the dialog("open")...nothing special here I don't think. My question: In Page B, how do I reference the dialog so I can do some things to it? For instance in Page B's content that I received back from that .ajax call and added to the div via .html(data), there is a button and when clicked I need to close the dialog. Right now my buttons are not working because one of them closes out the dialog and the other should redirect to a new page but both do not work now because I have no reference to the dialog that it's in to manipulate it.

  • backbonejs remove anomaly concept

    - by user1537158
    I was building a small app for adding and deleting li from ul using Backbonejs.One of the SO members cymen helped me code it, using that i tailored the code a little.currently if i add one element and delete , it works , but the second time i add an element (to ul) and go to delete it , i get Uncaught TypeError: Cannot call method 'remove' of undefined Pasting my code here , HTML : <input type="text" id="name"> <button id="add">Add</button> <ul id="mylist"></ul> JS: $(function(){ var myCollection = Backbone.Collection.extend(); var myView = Backbone.View.extend({ el:$('body'), tagName:'li', initialize : function(e){ this.collection.bind("add",this.render,this); this.collection.bind("remove",this.render,this); }, events:{ 'click #add' : 'addfoo' }, addfoo : function(){ var myname= $('#name').val(); $('#name').val(''); this.collection.add({name:myname}); }, render : function(){ $('#mylist').empty(); this.collection.each(function(model){ console.log("myView"); var remove = new myRemoveView({model:model}); remove.render(); }); } }); var myRemoveView = Backbone.View.extend({ el:$('body'), events:{ 'click .button':'removeFoo' }, removeFoo : function(){ console.log("here"); this.model.collection.remove(this.model); }, render : function(){ console.log("second view"); $('#mylist').append('<li>'+this.model.get('name') + "<button class='button'>"+"delete"+"</button></li>"); return; } }); var view = new myView({collection: new myCollection()}); }); Two things i did not understand : i) in the removeFoo function , we write this.model.collection.remove(this.model) shouldnt this have been this.collection.model.remove , something of that sort ? ii) i add a li to ul , then i delete it , when i add another li (appending to ul works perfect) but this time when i go to delete it throws me the above error : Uncaught TypeError :cannot call method 'remove' of undefined can you please help me figure out these 2 doubts in my code , btw SO member cymen's code works like a charm only my tailored code (above) is giving me errors.

  • Is there away to load a page only once with AJAX?

    - by digitup
    I have an AJAX call to load a function once the page is loaded, the function opens a lightbox a like frame with some data. The issue is that if I click on close (lightbox frame), the page loads again and again loading the frame so the use never reaches the page under the layer of frame since the frame load on infinite loop. The Ajax is repeating calling the function I guess but I would like to load the frame once and when the user clicks X (close) he may return to the original page. $(document).ready(function(){ var city = $('#citycode').html(); $.ajax({ //when page is loaded, fire the following function success: function(){ //the function to be fired located in the page in seperate file openX(city + //some other parameters); }}); }); Any tips?

  • Ordering z-indexes in an array

    - by Tom Gullen
    I have an array which looks something along the lines of resourceData[0][0] = "pic1.jpg"; resourceData[0][1] = 5; resourceData[1][0] = "pic2.jpg"; resourceData[1][1] = 2; resourceData[2][0] = "pic3.jpg"; resourceData[2][1] = 900; resourceData[3][0] = "pic4.jpg"; resourceData[3][1] = 1; The numeric represents the z-index of the image. Minimum z-index value is 1. Maximum (not really important) is 2000. I have all the rendering and setting z-indexes done fine. My question is, I want to have four functions: // Brings image to z front function bringToFront(resourceIndex) { // Set z-index to max + 1 resourceData[resourceIndex][1] = getBiggestZindex() + 1; // Change CSS property of image to bring to front $('#imgD' + resourceIndex).css("z-index", resourceData[resourceIndex][1]); } function bringUpOne(resourceIndex) { } function bringDownOne(resourceIndex) { } // Send to back z function sendToBack(resourceIndex) { } So given then index [3] (900 z): If we send it to the back, it will take the value 1, and [3] will have to go to 2, but that conflicts with [1] who has a 2 z-index so they need to go to three etc. Is there an easy programatical way of doing this because as soon as I start doing this it's going to get messy. It's important that the indexes of the array don't change. We can't sort the array unfortunately due to design. Update Thanks for answers, I'll post the functions here once they are written incase anyone comes across this in the future (note this code has zindex listed in [6]) // Send to back z function sendToBack(resourceIndex) { resourceData[resourceIndex][6] = 1; $('#imgD' + resourceIndex).css("z-index", 1); for (i = 0; i < resourceData.length; i++) { if (i != resourceIndex) { resourceData[i][6]++; $('#imgD' + i).css("z-index", resourceData[i][6]); } } }

  • JavaScript Show/Hide as Filters to list of divs

    - by deconspray
    Looking to create Javascript that acts like a filter on a list of divs. For instance, here's the intended markup... <a href="#" onclick="">Filter Item 1</a> <a href="#" onclick="">Filter Item 2</a> <a href="#" onclick="">Filter Item 3</a> <a href="#" onclick="">Filter Item 4</a> <a href="#" onclick="">Filter Item 5</a> <div class="1">Item 1</div> <div class="1">Item 1</div> <div class="2">Item 2</div> <div class="3">Item 3</div> <div class="1">Item 1</div> <div class="4">Item 4</div> <div class="4">Item 4</div> <div class="1">Item 1</div> <div class="5">Item 5</div> I want to be able to click on the link for Item 1, and show only Item 1 divs and hide all other divs, click the link of Item 2, and show only Item 2 divs and hide all other divs and so on. I've seen several similar scripts but nothing that seemingly turns divs matching the class on/off in this manner. TIA.

  • Why does setting document.domain require me to set it in all popups and iframes too?

    - by Chris
    I'm using a long-polling iframe solution for a chat script. Unfortunately, this requires me to set document.domain='yourdomain.com' in the iframe and main document, because the iframe is a subdomain call. The huge problem is...now all my other scripts that use popups and iframes are broken. They now require me to put document.domain in them too. It does fix it, but this is not an ideal solution at all. Is there another way around this problem?

  • Bind two images together to be dragged

    - by Ryan Beaulieu
    I'm looking for some help with a script to drag two images together at once. I currently have a script that allows me to drag thumbnail images into a collection bin to be saved later. However, some of my thumbnails have an image positioned over the top of them to represent these thumbnail images as "unknown" plants. I was wondering if someone could point me in the right direction as to how I would go about binding these two images together to be dragged. Here is my code: $(document).ready(function() { var limit = 16; var counter = 0; $("#mainBin1, #mainBin2, #mainBin3, #mainBin4, #mainBin5, #bin_One_Hd, #bin_Two_Hd, #bin_Three_Hd, #bin_Four_Hd, #bin_Five_Hd").droppable({ accept: ".selector, .plant_Unknown", drop: function(event, ui) { counter++; if (counter == limit) { $(this).droppable("disable"); } $(this).append($(ui.draggable).clone()); $("#cbOptions").show(); $(".item").draggable({ containment: "parent", grid: [72,72], }); } }); $(".selector").draggable({ helper: "clone", revert: "invalid", revertDuration: 700, opacity: 0.75, }); $(".plant_Unknown").draggable({ helper: "clone", revert: "invalid", revertDuration: 700, opacity: 0.75, }); }); Any help would be greatly appreciated. Thanks. EDIT: Website

  • How to call split(token) on a string that does not contain the token without causing an error?

    - by Vorinowsky
    I have two types of strings as the IDs of elements in my HTML markup: Dates: "april-23" "march-20" and season names: "springtime" "winter" The dates have a dash separating the month and the day. The seasons are a single word with no other tokens. I want to assign the month or the season to a new variable called: time_of_year If I do this: var time_of_year = $(this).attr("id").split('-')[0]; It will work on the months but if I call it on a season name which does not contain the token, will it generate an error? What's the safe way to do this?

  • focusout not triggering when clicking on another selector with a click

    - by Sean
    I have 2 divs that each have clicks bound to them. when you click on a div a form is displayed (in another div) that allows you to set properties specific to the div that is clicked. I'm using focusout to save the properties to a data object. everything is working perfectly except when i click on the other div. it seems that the click handler on the other div cancels out the focusout of the form field. Has anyone else experienced this? is so what is the proper way to overcome this?

  • How to make this JavaScript much faster?

    - by Ralph
    Still trying to answer this question, and I think I finally found a solution, but it runs too slow. var $div = $('<div>') .css({ 'border': '1px solid red', 'position': 'absolute', 'z-index': '65535' }) .appendTo('body'); $('body *').live('mousemove', function(e) { var topElement = null; $('body *').each(function() { if(this == $div[0]) return true; var $elem = $(this); var pos = $elem.offset(); var width = $elem.width(); var height = $elem.height(); if(e.pageX > pos.left && e.pageY > pos.top && e.pageX < (pos.left + width) && e.pageY < (pos.top + height)) { var zIndex = document.defaultView.getComputedStyle(this, null).getPropertyValue('z-index'); if(zIndex == 'auto') zIndex = $elem.parents().length; if(topElement == null || zIndex > topElement.zIndex) { topElement = { 'node': $elem, 'zIndex': zIndex }; } } }); if(topElement != null ) { var $elem = topElement.node; $div.offset($elem.offset()).width($elem.width()).height($elem.height()); } }); It basically loops through all the elements on the page and finds the top-most element beneath the cursor. Is there maybe some way I could use a quad-tree or something and segment the page so the loop runs faster?

  • Alert user when they hit the browser back button - with good reson

    - by Dirty Bird Design
    I know this borders on the taboo here, and please don't reply with "you should never do this etc" I have a very long form in a wizard, some users are too used to using the browsers back and forward buttons that they use those instead of the "Back" and "Next" buttons on the form wizard. If they hit the browsers back button they lose all of their form data which is a pain in the ass, since form is so long. Is it possible to display an alert that when will have a "take me out of here" and a "cancel" button so if they hit cancel it will cancel the function of the back button? Thanks!
