  • Reiterate over a jQuery plugin's this.each()

    - by eth0
    Hi, I'm making a plugin and one of the options is a standard callback. I want the user to be able to re-run the jQuery plugin's this.each() which basically re-runs the plugin, for example; callback: function(){ // some code to rerun the plugin here after 10 seconds } I know I can do this like so: $(this).plugin_name(); but it won't contain any of the options I've specified. Any help would be appreciated.

  • How do I select only the 4th and higher LIs in each UL?

    - by KatieK
    For this XHTML: <ul class="collapse"> <li>One</li> <li>Two</li> <li>Three</li> <li>Four</li> <li>Five</li> </ul> <ul class="collapse"> <li>1</li> <li>2</li> <li>3</li> <li>4</li> </ul> Using jQuery, how do I select only the 4th and higher LIs in each UL? I've tried: $("ul.collapse li:gt(2)").css("color", "red"); But it selects the 4th and higher LIs in the whole document. "Four", "Five", and "1", "2", "3", "4" are red.

  • jquery ajax calls with scope safety

    - by acidzombie24
    My gut tells me that if i am on a laggy server and the user fires two events fast enough on the success function c will be the value of the most recent event causing func1 to use the wrong value. <--- This is a guess, i haven't proved it. Its a feeling. How do i ensure that i use the right value when calling func1? I prefer not to send c to the server and i dont know if or how to serialize the data and deserialize it back. How do i make this code safe? $('.blah').click(function (event) { var c = $(this).closest('.comment'); ... $.ajax({ url: "/u", type: "POST", dataType: "json", data: { ... }, success: function (data) { func1(c. data.blah);//here

  • Coffeescript getting proper scope from callback method

    - by pandabrand
    I've searched for this and can't seem to find an successful answer, I'm using a jQuerey ajax call and I can't get the response out to the callback. Here's my coffeescript code: initialize: (@blog, @posts) -> _url = @blog.url _simpleName = _url.substr 7, _url.length _avatarURL = exports.tumblrURL + _simpleName + 'avatar/128' $.ajax url: _avatarURL dataType: "jsonp" jsonp: "jsonp" (data, status) => handleData(data) handleData: (data) => console.log data @avatar = data Here's the compiled JS: Blog.prototype.initialize = function(blog, posts) { var _avatarURL, _simpleName, _url, _this = this; this.blog = blog; this.posts = posts; _url = this.blog.url; _simpleName = _url.substr(7, _url.length); _avatarURL = exports.tumblrURL + _simpleName + 'avatar/128'; return $.ajax({ url: _avatarURL, dataType: "jsonp", jsonp: "jsonp" }, function(data, status) { return handleData(data); }); }; Blog.prototype.handleData = function(data) { console.log(data); return this.avatar = data; }; I've tried a dozen variations and I can't figure out how to write this? Thanks.

  • How to pass a variable inside a jquery fonction $.each($("abc")...?

    - by Rock
    I'm trying to iterate a bunch of SELECT OPTION html drop-down fields and from the ones that are NOT empty, take the values and add a hidden field for a PAYPAL shopping cart. My problem is that for some reason, the variable "curitem" is not passed inside the each function and I can't add the hidden field like they should. All I get is "NaN" or "undefined". What PAYPAL expect is : item_name_1, item_name_2, etc. All numbers must iterate by +1. How can I do this? Thanks a bunch in advance var curitem; $.each($("select"), function(index, item) { var attname = $(this).attr("name"); var nom = $(this).attr("data-nom"); var prix = $(this).attr("data-val"); var partname = attname.substring(0, 1); var qte = $(this).val(); // i want all my <select option> items that the NAME start with "q" AND have a value selected if (partname == "q" && isNaN(qte) == false && qte > 0) { // item name var inp2 = document.createElement("input"); inp2.setAttribute("type", "hidden"); inp2.setAttribute("id", "item_name_"+curitem); inp2.setAttribute("name", "item_name_"+curitem); inp2.setAttribute("value", nom); // amount var inp3 = document.createElement("input"); inp3.setAttribute("type", "hidden"); inp3.setAttribute("id", "amount_"+curitem); inp3.setAttribute("name", "amount_"+curitem); inp3.setAttribute("value", prix); // qty var inp4 = document.createElement("input"); inp4.setAttribute("type", "hidden"); inp4.setAttribute("id", "quantity_"+curitem); inp4.setAttribute("name", "quantity_"+curitem); inp4.setAttribute("value", qte); // add hidden fields to form document.getElementById('payPalForm').appendChild(inp2); document.getElementById('payPalForm').appendChild(inp3); document.getElementById('payPalForm').appendChild(inp4); // item number curitem = curitem + 1; } });

  • Is there a way to have a dynamic google map that opens links in _blank?

    - by danieltalsky
    I came up with a good solution for a client showing a google map iFrame using the normal google maps embed. Only problem? They want the links inside the iFrame to open in a new window instead of there on the page. So, I used the static API to come up with a static image of a map and have that link to the google maps site with target="_blank". Great, but they don't get the pretty draggable map. Is there a way to do what I want using the google maps API? I'm reading the API documentation but without actually trying it I'm not sure if it can be done, and would love it if someone with some experience with the API can point me in the right direction or just tell me why it's WAY not worth the effort.

  • Which browsers support html5 offline storage?

    - by Marcin
    Essentially, I wanted to run a piece of demo code from W3c Offline Webapps page. It looks like that: var db = window.openDatabase("notes", "", "The Example Notes App!", 1048576); Firefox 3.5, IE8 and Chrome do not seem to get it. Is there anybody out there that actually wrote support for that? Or is this wishful thinking about 'the standard of the future'?

  • JQuery within a partial view not being called

    - by XN16
    I have a view that has some jQuery to load a partial view (via a button click) into a div in the view. This works without a problem. However within the partial view I have a very similar bit of jQuery that will load another partial view into a div in the first partial view, but this isn't working, it almost seems like the jQuery in the first partial view isn't being loaded. I have tried searching for solutions, but I haven't managed to find an answer. I have also re-created the jQuery function in a @Ajax.ActionLink which works fine, however I am trying to avoid the Microsoft helpers as I am trying to learn jQuery. Here is the first partial view which contains the jQuery that doesn't seem to work, it also contains the @Ajax.ActionLink that does work: @model MyProject.ViewModels.AddressIndexViewModel <script> $(".viewContacts").click(function () { $.ajax({ url: '@Url.Action("CustomerAddressContacts", "Customer")', type: 'POST', data: { addressID: $(this).attr('data-addressid') }, cache: false, success: function (result) { $("#customerAddressContactsPartial-" + $(this).attr('data-addressid')) .html(result); }, error: function () { alert("error"); } }); return false; }); </script> <table class="customers" style="width: 100%"> <tr> <th style="width: 25%"> Name </th> <th style="width: 25%"> Actions </th> </tr> </table> @foreach (Address item in Model.Addresses) { <table style="width: 100%; border-top: none"> <tr id="[email protected]"> <td style="width: 25%; border-top: none"> @Html.DisplayFor(modelItem => item.Name) </td> <td style="width: 25%; border-top: none"> <a href="#" class="viewContacts standardbutton" data-addressid="@item.AddressID">ContactsJQ</a> @Ajax.ActionLink("Contacts", "CustomerAddressContacts", "Customer", new { addressID = item.AddressID }, new AjaxOptions { UpdateTargetId = "customerAddressContactsPartial-" + @item.AddressID, HttpMethod = "POST" }, new { @class = "standardbutton"}) </td> </tr> </table> <div id="[email protected]"></div> } If someone could explain what I am doing wrong here and how to fix it then I would be very grateful. Thanks very much.

  • Google Chrome window.open height includes URL bar

    - by andyjeffries
    When we open a window using: window.open("/calendar",'calendar','width=950,height=576,titlebar=no,statusbar=no,menubar=no,resizable=no,scrollbars=no'); Firefox 3 and IE 7 open it to have a content area height of 576 plus the browser items (URL bar, status bar, etc). Chrome however opens it to have a total height of 576 meaning a scrollbar appears to the right of the content (and then the bottom because the width is now reduced). How can I get around this? It's for a heavy layout part of a web app so it's not just a matter of "let the user scroll", the client doesn't want that. Has anyone come across this? I don't mind browser sniffing and opening the window bigger, but I know that's yucky these days.

  • travesersing the dom with inexact parameters

    - by rashcroft23
    Hi, I want to grab the image src on a product page in a e commerce website. I'm writing this as a bookmarklet, so I'd like the code to work universally as possible. I've noticed that there are only two reoccurring factors in the product image tag among top e-commerce websites (amazon, bestbuy ect.): border=0 and 180<width&height<400. So how could I write a selector that would give me the srcof the first img element on the page with no border and width & height between 180 and 400 px? Or is there a better way of doing this? P.S. since I'm trying to keep the bookmarklet as light as possible, I don't want to use any libraries (jquery, yui etc)

  • jQuery $.each()-problem

    - by Volmar
    Hi, im making a wordpress plugin and i have a function where i import images, this is done with a $.each()-loop that calls a .load()-function every iteration. The load-function page the load-function calls is downloading the image and returns a number. The number is imported into a span-element. The source and destination Arrays is being imported from LI-elemnts of a hidden ULs. this way the user sees a counter counting from zero up to the total number of images being imported. You can se my jQuery code below: jQuery(document).ready(function($) { $('#mrc_imp_img').click(function(){ var dstA = []; var srcA = []; $("#mrc_dst li").each(function() { dstA.push($(this).text()) }); $("#mrc_src li").each(function() { srcA.push($(this).text()) }); $.each(srcA, function (i,v) { $('#mrc_imgimport span.fc').load('/wp-content/plugins/myplugin/imp.php?num='+i+'&dst='+dstA[i]+'&src='+srcA[i]); }); }); }); This works pretty good but sometimes it looks like the load function isn't updating the DOM as fast as it should because sometimes the numbers that the span is updated with is lower than the previous and almost everytime a lower number is replacing the last number in the end. How can i prevent this from happening and how can i make it hide '#mrc_imp_img' when the $.each-loop is ready?

  • What is XML good for and when should i be using it?

    - by Haroldo
    I'm curious, I've been developing pretty powerful websites/web apps, and I've never learnt XML, even odder I've never really felt the need to. It's not like Curl or Prepared Statements where before knowing what they did and how they worked I had a feeling 'there's got to be an easier way to do this!' or 'there's got to be something designed for this!'. Currently I work with MySQL and JSON and I don't have this feeling of 'I need to learn that' (XML), this must be wrong! I'm really interested to hear some compelling arguments for XML, and learn about things which it can do beter than JSON or MySQL (or some other aspect of web dev) and when i should be using it!

How can I test js in this situation. Or is there and brower that works without X11 installed like wget? Thanks.

  • jQuery selector - style values

    - by kender
    I got a series of divs like this: <div class="message" style="padding-left: 0px;">...</div> <div class="message" style="padding-left: 20px;">...</div> <div class="message" style="padding-left: 20px;">...</div> <div class="message" style="padding-left: 40px;">...</div> <div class="message" style="padding-left: 20px;">...</div> And I would like to make a selector that would get me the divs with padding greater then 20px. Would it be possible with just using jquery? Or I should modify my html tree and add some attribute that would distinguish those elemenents with high padding value?

  • jQuery: Any way to "refresh" event handlers?

    - by Legend
    I have two divs, one that holds some stuff and the other with all possible stuff. Clicking on one of the divs will transfer items to the other div. The code I came up with is: $("#holder > *").each(function() { $(this).click(function(e) { $(this).remove(); $("#bucket").append(this); }); }); $("#bucket > *").each(function() { $(this).click(function(e) { $(this).remove(); $("#holder").append(this); }); }); This one works perfectly, except that the event handlers need to be refreshed once I append or remove elements. What I mean is, if I first click on an element, it gets added to the other div, but if I click on this element again, nothing happens. I can do this manually but is there a better way to achieve this?
