• How to select the first property with unknown name and first item from array in JSON

  - by Oscar Godson

  I actually have two questions, both are probably simple, but for some odd reason I cant figure it out... I've worked with JSON 100s of times before too! but here is the JSON in question: {"69256":{ "streaminfo":{ "stream_ID":"1025", "sourceowner_ID":"2", "sourceowner_avatar":"http:\/\/content.nozzlmedia.com\/images\/sourceowner_avatar2.jpg", "sourceownertype_ID":"1", "stream_name":"Twitter", "streamtype":"Social media" "appsarray":[] }, "item":{ "headline":"Charboy", "main_image":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg", "summary":"ate a tomato and avocado for dinner...", "nozzl_captured":"2010-05-12 23:02:12", "geoarray":[{ "state":"OR", "county":"Multnomah", "city":"Portland", "neighborhood":"Downtown", "zip":"97205", "street":"462 SW 11th Ave", "latitude":"45.5219", "longitude":"-122.682" }], "full_content":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.", "body_text":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.", "author_name":"Charboy", "author_avatar":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg", "fulltext_url":"http:\/\/twitter.com\/charboy\/statuses\/13889868936", "leftovers":{ "twitter_id":"tag:search.twitter.com,2005:13889868936", "date":"2010-05-13T02:59:59Z", "location":"iPhone: 45.521866,-122.682262" }, "wordarray":{ "0":"ate", "1":"tomato", "2":"avocado", "3":"dinner", "4":"tonight", "5":"tasty", "6":"foods", "7":"just", "8":"enjoyable", "9":"Charboy", "11":"Twitter", "13":"state:OR", "14":"county:Multnomah, OR", "15":"city:Portland, OR", "16":"neighborhood:Downtown", "17":"zip:97205" } } } } Question 1: How do I loop through each item (69256) when the number is random? e.g. item 1 is 123, item2 is 646? Like, for example, a normal JSON feed would have something like: {'item':{'blah':'lorem'},'item':{'blah':'ipsum'}} the JS would be like console.log(item.blah) to return lorem then ipsum in a loop How do I do it when i dont know the first item of the object? Question 2: How do I select items from the geoarray object? I tried: json.test.item.geoarray.latitude and json.test.item.geoarray['latitude']

• is JsonP working with Opera, Chrome & Safari ?

  - by Tom

  Hi, On a web site that I am building , when you log in (because the database is on an other server), I use json padding to check if the user as the right credentials. It's working flawlessly (ie7,ie8 & FF), until I tried it on chrome, safari & opera where it's a complete disaster. $.ajax({ type: "GET", dataType: "jsonp", url: "http://someurl.com", data: aRequestData, cache: false, error: function (XMLHttpRequest, textStatus, errorThrown) { // typically only one of textStatus or errorThrown // will have info alert("Error occured textStatus=" + textStatus + " errorThrown=" + errorThrown); }, success: function(data) { alert('success'); } }); Plain and simple and it works in browser window, however, to my big surprise it did not work in chrome, safari & opera, never got to the success alert. Does anyone know how to solve this issue? Thanks.

• How can you tell if an HTML dropdown is displaying the list of options

  - by Ross Goddard

  Is there a way to determine if a given drop down is currently active and displaying it's list of options? I am currently binding to the mousedown event of the dropdown and populating the options when the user clicks on it. Unfortunately the mousedown event fires when the user selects the option as well. If I can determine if the drop down is already displaying it's options, then I can skip populating the options.

• getjson and servers

  - by gheil.apl

  Is getJSON only useful for those who control a server? Is there any other alternative for getting data from a file? i tried $.getJSON("good.json", function(data){ out=out+"good.json: "+data + ","; }); where good.json = {"a":"1","b":"2"} and got a result of 'null' for data. These all are valid JSON files, and all give null when used in the above: good.htm assoc.json assoc.js stub.json stub.js test.js test.txt and all get a null result... The above is in an interactive setting at http://jsbin.com/dbJSON/8/edit the output (of null) is to be had by clicking 'output'.

• JavaScript check field value based on variable value

  - by Nikita Sumeiko

  I have an anchor like this: <a href="#" rel="1 4 7 18 ">Anchor</a> Where 'rel' attribute values are ids of some items. Than I have a form with an input, where user should type an id and click submit button. On submit button click I need to check the value of input like this: var value = $('a').attr('rel'); if ( value == '1' || value == '4' || value == '7' || value == '18') { // however I need the line above are created dynamically based on 'value' var alert('The id exists'); return false; } else { return true; } So, the question is how to create a line below dynamically based on anchor 'rel' attribute values?! This is the line: if ( value == '1' || value == '4' || value == '7' || value == '18') {

• Problem in loading cities using JSON

  - by Saravanan I M

  I am using Geonames for loading the cities using JSON. Geonames data i imported into my database. I am using MS SQL 2008 Server. I display a dropdown for country select. Once the user select the country. I am loading all the cities into the autocomplete textbox. I am facing a delay in the getJSON method. Also it seems like executing asynchronous. So before getting all the data my autocompelte is getting filled. Below is my complete script. I think i have some problem in the loop. Please advice me what i am doing wrong in my code. $(document).ready(function () { $("#ShowLoad").hide(); //Hook onto the MakeID list's onchange event $("#Country").change(function () { findcities = []; $("#ShowLoad").show(); $("#HomeTown").unautocomplete(); var url = '<%= Url.Content("~/") %>' + "Location/GetCitiesCountByCountry/" + $("#Country").val(); $.getJSON(url, null, function (data) { var total = data; if (total > 0) { var pageTotal = Math.ceil(total / 1000); var isFilled = false; for (var i = 0; i < pageTotal; i++) { var skip = i == 1 ? 0 : (i * 1000) - 1000; var url = '<%= Url.Content("~/") %>' + "Location/GetCitiesByCountry/" + $("#Country").val() + "?skip=" + skip; //alert(i); $.getJSON(url, null, function (data) { $.each(data.Cities, function (index, optionData) { if ($("#Country").val() == "US") { findcities.push(optionData.asciiname + "," + optionData.admin1_code); } else { findcities.push(optionData.asciiname); } }); if (i == pageTotal) { //alert(findcities); $("#ShowLoad").hide(); $("#HomeTown").focus().autocomplete(findcities); } }); } $("#HomeTown").setOptions({ max: 100000 }); } }); }).change(); });

• CodeIgniter - Post multiple arrays to controller

  - by Bobe

  I have a dynamically generated form that allows users to enter new data and edit existing data. When the form is submitted, it collates the input values and groups them according to whether they are new or not, the former being denoted by class="new-entry". So the function generates two arrays: updateData and insertData. Both arrays are of similar formats: [ 0: { 'id' = 1, 'value' = foo }, 1: { 'id' = 1, 'value' = 'bar' }, etc... ] I am combining them into a new array object to send via ajax to the controller: var postData = { 'update_data': updateData, 'insert_data': insertData }; Then in the ajax call: $.post(url, postData, function() { // some code }); However, in the controller, doing print_r($this->input->post()) or print_r($_POST) as a test only returns Array(). Even $this->input->post('update_data') returns nothing. How can I retrieve these arrays in the controller?

• MVC Rendered Partial, how to get partial/view model in main model post to controller

  - by user1475788

  I have a text file and when users upload the file, the controller action method parses that file using state machine and uses a generic list to store some values. I pass this back to the view in the form of an IEnumerable. Within my main view, based on this ienumerable list I render a partail view to iterate items and display labels and a textarea. Users could add their input in the text area. When the users hit the save button this ienumrable list from the partial view rendered is null. so please advice any solutions. here is my main view @model RunLog.Domain.Entities.RunLogEntry @{ ViewBag.Title = "Create"; Layout = "~/Views/Shared/_Layout.cshtml"; } @using (Html.BeginForm("Create", "RunLogEntry", FormMethod.Post, new { enctype = "multipart/form-data" })) { <div id="inputTestExceptions" style="display: none;"> <table class="grid" style="width: 450px; margin: 3px 3px 3px 3px;"> <thead> <tr> <th> Exception String </th> <th> Comment </th> </tr> </thead> <tbody> @if (Model.TestExceptions != null) { foreach (var p in Model.TestExceptions) { Html.RenderPartial("RunLogTestExceptionSummary", p); } } </tbody> </table> </div> } partial view as follows: @model RunLog.Domain.Entities.RunLogEntryTestExceptionDisplay <tr> <td> @Model.TestException@ </td> <td>@Html.TextAreaFor(Model.Comment, new { style = "width: 200px; height: 80px;" }) </td> </tr> Controller action [HttpPost] public ActionResult Create(RunLogEntry runLogEntry, String ServiceRequest, string Hour, string Minute, string AMPM, string submit, IEnumerable<HttpPostedFileBase> file, String AssayPerformanceIssues1, IEnumerable<RunLogEntryTestExceptionDisplay> models) { } The problem is test exceptions which contains exception string and comment is comming back null.

• Javascript Mouseover bubbling from children

  - by Nicky De Maeyer

  Ive got the following html setup: <div id="div1"> <div id="content1">blaat</div> <div id="content1">blaat2</div> </div> it is styled so you can NOT hover div1 without hovering one of the other 2 divs. Now i've got a mouseout on div1. The problem is that my div1.mouseout gets triggered when i move from content1 to content2, because their mouseouts are bubbling. and the event's target, currentTarget or relatedTarget properties are never div1, since it is never hovered directly... I've been searching mad for this, but I can only find articles and solutions for problems who are the reverse of what I need. It seems trivial but I can't get it to work... The mouseout of div1 should ONLY get triggered when the mouse leaves div1. One of the possibilities would be to set some data on mouse enter and mouseleave, but I'm convinced this should work out of the box, since it is just a mouseout... EDIT: bar.mouseleave(function(e) { if ($(e.currentTarget).attr('id') == bar.attr('id')) { bar.css('top', '-'+contentOuterHeight+'px'); $('#floatable-bar #floatable-bar-tabs span').removeClass('active'); } }); changed the mouseout to mouseleave and the code worked...

• Why does a checkbox's "checked" attribute return the opposite of it's actual value on click event?

  - by Kappers

  I've got the following HTML <li><input type="checkbox" /><label>This is the label!</label></li> I bound a click event to the li, and let the click event bubble up to the li before doing anything else. $('li').each(function(i){ var item = $(this); var checkbox = $("input[type='checkbox']", item); item.bind('click', function(e){ var isChecked = checkbox.is(':checked'); console.log(isChecked); e.stopPropagation(); }); }); Starting with an unchecked checkbox, when the click event fires, isChecked returns true when I click on the checkbox, but returns false when I click on the label or li. Does anyone know why?

• Javascript array of href's

  - by Jason

  Hi, I am trying to create an array with different href's to then attach to 5 separate elements. This is my code: var link = new Array('link1', 'link2', 'link3', 'link4', 'link5'); $(document.createElement("li")) .attr('class',options.numericId + (i+1)) .html('<a rel='+ i +' href=\"page.php# + 'link'\">'+ '</a>') .appendTo($("."+ options.numericId)) As you can see I am trying to append these items from the array to the end of my page so each link will take the user to a different section of the page. But i have not been able to do this. Is there a way to to create elements with different links? I am new to javascript so I am sorry if this doesn't make a whole lot of sense. If anyone is confused by what i am asking here I can try to clarify if I get some feedback. Any solutions would be greatly appreciated. Thanks, jason

• Google Maps: How does Trulia create their custom InfoWIndows?

  - by NickT

  I really like how Trulia.com has created their custom Google Map InfoWindows. What I like in particular about Trulia's implementation of the InfoWindow is: Extends beyond the map border: Google Maps InfoWindows are contained within the map border whereas Trulia's seems to be able to float on-top of the map Always displays InfoWindow near map Center: Google Maps InfoWindows always display the InfoWindow above the marker whereas Trulia InfoWindows always display the InfoWindow as close the center of the map as possible. For example, if the map marker icon is on the top of the map near the border, the Trulia InfoWindow is displayed below the map marker icon InfoWindow is displayed on mouse hover (not 'click'): With the default Google Maps InfoWindow, you have to 'click' the map marker icon to display the InfoWindow whereas Trulia InfoWindows are display simply by hovering over the map marker icon. I found the PdMarker, which is a 3rd party extension for Google Map InfoWindows that accomplishes most of the above bullets but not all. 1) It does not extend beyond the map border, 2) it does not work with Google Maps API version 3 (only version 2). Anyone know how Trulia is accomplishing their InfoWindow-like implementation on Google Maps API v3?
