  • Sorting issues in flexigrid with "json" data

    - by John Sieber
    I'm currently using flexigrid to display data in a current project, but am running into issues with its ability to properly sort certain columns that contain dates or numbers. The data is being sent from a ColdFusion CFC that selects the appropriate data and then delivers it in the proper "json" format. As the date/time stamps and other fields containing numbers are sent as "strings" they do not sort properly in the data grid. Is this a limitation of Flexigrid or am I sending the data improperly to Flexigrid? I can provide examples of my code if that is helpful.

  • optimized search using ajax and keypress

    - by ooo
    i have the following code as i want to search a database as a user is typing into a textbox. This code below works fine but it seems a little inefficient as if a user is typing really fast, i am potentially doing many more searches than necessary. So if a user is typing in "sailing" i am searching on "sail", "saili", "sailin", and "sailing" i wanted to see if there was a way to detect any particular time between keypresses so only search if user stops typing for 500 milliseconds or something like this. is there a best practices for something like this? $('#searchString').keypress(function(e) { if (e.keyCode == 13) { var url = '/Tracker/Search/' + $("#searchString").val(); $.get(url, function(data) { $('div#results').html(data); $('#results').show(); }); } else { var existingString = $("#searchString").val(); if (existingString.length > 2) { var url = '/Tracker/Search/' + existingString; $.get(url, function(data) { $('div#results').html(data); $('#results').show(); }); } }

    - by raffaello123
    I tried maaaany script but every time I get stuck in something bad. My goal is to create rounded boxes for links. You can see an example of I'm talking about here in the read more link (effects not necessary). Very common I know, but I want to make it work in eeeevery browsers at least safari, FF, chrome and most important IE7+ (IE6 not necessary...). The script that took me closest to the solution is Cornerz but I can't fix a very bad issue on IE8. Does anybody knows a way to get rid of this or to achieve my goal? Thank you I appreciate every support. Cheers

  • How to call a set of variables functions based on class on a group of elements

    - by user1547007
    I have the following html code: <i class="small ele class1"></i> <i class="medium ele class1"></i> <i class="large ele class1"></i> <div class="clear"></div> <i class="small ele class2"></i> <i class="medium ele class2"></i> <i class="large ele class2"></i> <div class="clear"></div> <i class="small ele class3"></i> <i class="medium ele class3"></i> <i class="large ele class3"></i> <div class="clear"></div> <i class="small ele class4"></i> <i class="medium ele class4"></i> <i class="large ele class4"></i>? And my javascript looks like so: var resize = function(face, s) { var bb = face.getBBox(); console.log(bb); var w = bb.width; var h = bb.height; var max = w; if (h > max) { max = h; } var scale = s / max; var ox = -bb.x+((max-w)/2); var oy = -bb.y+((max-h)/2); console.log(s+' '+h+' '+bb.y); face.attr({ "transform": "s" + scale + "," + scale + ",0,0" + "t" + ox + "," + oy }); } $('.ele').each(function() { var s = $(this).innerWidth(); var paper = Raphael($(this)[0], s, s); var face = $(this).hasClass("class1") ? class1Generator(paper) : class4Generator(paper); /*switch (true) { case $(this).hasClass('class1'): class1Generator(paper); break; case $(this).hasClass('class2'): class2Generator(paper) break; case $(this).hasClass('class3'): class3Generator(paper) break; case $(this).hasClass('class4'): class4Generator(paper) break; }*/ resize(face, s); }); my question is, how could I make this line of code more scalable? I tried using a switch but The script below is calling two functions if one of the elements has a class, but what If i have 10 classes? I don't think is the best solution I created a jsFiddle http://jsfiddle.net/7uUgz/6/ //var face = $(this).hasClass("awesome") ? awesomeGenerator(paper) : awfulGenerator(paper);

  • How do I upload a file when I know the client's filepath?

    - by GJTorikian
    I'm interested in the way Sonic Living detects your iTunes library XML file. It prompts the user to approve its actions, then automatically uploads the XML file based on the client OS (and assuming the default installation path of iTunes). How the heck does it do that? None of the upload libraries I've looked at have this feature. They all assume that a user will click "Select file..." then browse around for the right thing to upload.

  • Best way of showing more results with javascript/css

    - by Ricardo Neves
    I'm developing a website and i'm having troubles showing the search results to the user the way I want. Basically, after the user search, the page makes a couple of ajax requests and as soon as a response arrive it appends the info to a specific element on my page. Each results is shown as a line... The problem is that in most case there are going to be more than 1000 results and this would make the page have a large scroll. My idea was to show only the first 15 results and when the user clicks "show more" the element would expand and show the next 15 results and so on... This would be easier to do if the website wasn't responsive, but because it is I can't find the proper way of implementing what I want without lowering the website perfomance. I have "2 ideas": The first is by using something like #element .div:nth-child(-n+15) on my css and figure a way of changing the "15" to how much results I want to show... I don't know if this can be done. Is it possible to call css rules with parameters? Maybe with less css? The second option is probably a bad option if i don't want to lower the website performance. Using javascript I would check if there is a specific css class(like .show-15 .show30 .show45) and add that class to my element and if it don't exist, create it somehow.. Any help would be appreciated.

  • How to filter using a dropdown in Knockout

    - by user517406
    I have just started using Knockout and I want to filter my data that I am displaying in my UI by selecting an item from a dropdown. I have got so far, but I cannot get the selected value from my dropdown yet, and then after that I need to actually filter the data displayed based upon that value. Here is my code so far : @model Models.Fixture @{ ViewBag.Title = "Fixtures"; Layout = "~/Areas/Development/Views/Shared/_Layout.cshtml"; } @Scripts.Render("~/bundles/jqueryval") <script type="text/javascript" src="@Url.Content("~/Scripts/knockout-2.1.0.js")"></script> <script type="text/javascript"> function FixturesViewModel() { var self = this; var baseUri = '@ViewBag.ApiUrl'; self.fixtures = ko.observableArray(); self.teams = ko.observableArray(); self.update = function (fixture) { $.ajax({ type: "PUT", url: baseUri + '/' + fixture.Id, data: fixture }); }; self.sortByAwayTeamScore = function () { this.fixtures.sort(function(a, b) { return a.AwayTeamScore < b.AwayTeamScore ? -1 : 1; }); }; self.select = function (team) { }; $.getJSON("/api/fixture", self.fixtures); $.getJSON("/api/team", self.teams); } $(document).ready(function () { ko.applyBindings(new FixturesViewModel()); }); </script> <div class="content"> <div> <table><tr><td><select data-bind="options: teams, optionsText: 'TeamName', optionsCaption: 'Select...', optionsValue: 'TeamId', click: $root.select"> </select></td></tr></table> <table class="details ui-widget-content"> <thead> <tr><td>FixtureId</td><td>Season</td><td>Week</td><td>AwayTeam</td><td><a id="header" data-bind='click: sortByAwayTeamScore'>AwayTeamScore</a></td><td>HomeTeam</td><td>HomeTeamScore</td></tr> </thead> <tbody data-bind="foreach: fixtures"> <tr> <td><span data-bind="text: $data.Id"></span></td> <td><span data-bind="text: $data.Season"></span></td> <td><span data-bind="text: $data.Week"></span></td> <td><span data-bind="text: $data.AwayTeamName"></span></td> <td><input type="text" data-bind="value: $data.AwayTeamScore"/></td> <td><span data-bind="text: $data.HomeTeamName"></span></td> <td><input type="text" data-bind="value: $data.HomeTeamScore"/></td> <td><input type="button" value="Update" data-bind="click: $root.update"/></td> </tr> </tbody> </table> </div> </div> Can anybody please advise on this?

  • How to make technical training session useful and successful for trainee?

    - by metal-gear-solid
    Are these suggestions good to give for a successful training session? Practice time should be always given immediate after technical training? usually after receiving any technical session about any new thing we do routine work. If we don't do practice just after training, later when we do any work related to that training then we feel we need training again. So if we are getting training today and will not use it for some period of time (15 -30 -60 days) then the training is of no use, as it is at the wrong time. I.e. We will forget many things Any other suggestions which i should give? I'm trainee not trainer. What suggestion should i give to trainer/organizer?

  • css override not working?

    - by Karin
    I have three tabs that change styles when clicked. class="active" gives the tab the same background as the tab content, while class="inactive" has another color. My problem is the text on the tabs, something's weird with the CSS. The default state of class="active" looks as it should, while the inactive tabs are underlined even though my CSS says text-decoration: none !important; and the clicked active tab text becomes extra bold (or maybe it's a shadow). Please look at my fiddle: http://jsfiddle.net/m8wQM/170/

  • jqGrid: Is it possible to commit a cell change when tabbing off instead of pressing Enter?

    - by The Matt
    I have a simple in-line edit in my grid, and I want to commit the change when the user tabs off the textbox. The default behavior of jqGrid forces the user to press 'Enter' to commit the change, but this is non-intuitive for our users. onSelectRow: function(id) { $(gridCoreGroups).editRow(id, true, undefined, function(response) { alert("hello world"); } } I've worked my way through the events provided, but they all happen as a result of the user pressing 'Enter', which I want to avoid. Is there something I can wire up that would trigger an action when the user tabs off this cell?

  • Why does this php/ajax query fail?

    - by Ashley Brown
    I'm ajaxing over to this php file. $a = 'old'; $b = 'new'; if ($_POST['info-type'] == $a || $b) { $info = $_POST['info-type']; $query = "SELECT * FROM `tld` WHERE type = '".$var."'"; } $query = "SELECT * FROM `tld` "; $result = mysqli_query($link,$query); while($row = mysqli_fetch_assoc($result)) { echo '<div>'.$row['something'].'</div>'; } The data posted is either 'all' 'new' or 'old'. If i send the data as either new or old, the script works and outputs as expected. If the posted data is neither new or old but all instead, it fails and don't show any errors or respond anything back. (I've monitored via dev tools aswell) So, I tried this if ($_POST['info-type'] == $a || $b) { $info = $_POST['info-type']; $var = "SELECT * FROM `tld` WHERE type = '".$var."'"; } elseif ($_POST['info-type'] == 'all'){ $query = "SELECT * FROM `tld` "; } But the script still fails. If i fully remove the IF statements and use the query without the WHERE clause like it is after the elseif, it works?

  • Cascading dropdowns

    - by SnowJim
    Hi! I am working with cascading dropdowns in MVC. It appears that I will not be able to easily create dropdowns on demand, instead I will have to add the dropdowns before sending it to the client. This is how I am doing it right now: In the aspx page <%: Html.DropDownListFor(model => model.ModelViewAd.Category1, Model.ModelViewAd.Category1List, "-- Välj kategori --")%> <%: Html.DropDownListFor(model => model.ModelViewAd.Category2, Model.ModelViewAd.Category2List, "-- Välj kategori --")%> <%: Html.DropDownListFor(model => model.ModelViewAd.Category3, Model.ModelViewAd.Category3List, "-- Välj kategori --")%> <%: Html.DropDownListFor(model => model.ModelViewAd.Category4, Model.ModelViewAd.Category4List, "-- Välj kategori --")%> This is rendered like this : <select id="ModelViewAd_Category1" name="ModelViewAd.Category1"> <option value="">-- V&#228;lj kategori --</option> <option value="10">Fordon</option> <option value="15">F&#246;r hemmet</option> <option value="17">Bostad</option> </select> <select id="ModelViewAd_Category2" name="ModelViewAd.Category2"> <option value="">-- V&#228;lj kategori --</option> </select> <select id="ModelViewAd_Category3" name="ModelViewAd.Category3"> <option value="">-- V&#228;lj kategori --</option> </select> <select id="ModelViewAd_Category4" name="ModelViewAd.Category4"> <option value="">-- V&#228;lj kategori --</option> </select> This is what the script on the page looks like: <script type="text/javascript"> $(function () { $("select#ModelViewAd_Category1").change(function () { var id = $(this).val(); var urlAction = "/AdCategory/GetCategoriesByParent1/" + id; $.getJSON(urlAction, { id: id }, function (data) { $("#ModelViewAd_Category2").addItems(data.d); }); }); $("select#ModelViewAd_Category2").change(function () { var id = $(this).val(); var urlAction = "/AdCategory/GetCategoriesByParent1/" + id; $.getJSON(urlAction, { id: id }, function (data) { $("#ModelViewAd_Category3").addItems(data.d); }); }); $("select#ModelViewAd_Category3").change(function () { var id = $(this).val(); var urlAction = "/AdCategory/GetCategoriesByParent1/" + id; $.getJSON(urlAction, { id: id }, function (data) { $("#ModelViewAd_Category4").addItems(data.d); }); }); }); </script> And then I have an included file that contains this: $.fn.clearSelect = function () { return this.each(function () { if (this.tagName == 'SELECT') this.options.length = 0; }); } $.fn.addItems = function (data) { return this.clearSelect().each(function () { if (this.tagName == 'SELECT') { var dropdownList = this; $.each(data, function (index, optionData) { var option = new Option(optionData.Text, optionData.Value); if ($.browser.msie) { dropdownList.add(option); } else { dropdownList.add(option, null); } if ($(this).children().size() < 2) { $(this).hide(); } else { $(this).show(); } }); } }); } The problem I now have is that I need to hide the dropdowns that do not contain any options or only contain one option. This should be checked when doing a call to the service as well as when the page is sent to the client ("POSTBACK"). What I need is : 4 Dropdowns Only the first dropdown is visible when first entering the page. When selecting an option from dropdown1 the dropdown2 will be populated and so on If there is only 1 option then the dropdown should be hidden If all 4 dropdowns are set and the end-user changes dropdown1, then dropdown2 should be reloaded and the rest be hidden If the user has selected some of the dropdowns (say 1, 2 and 3) and hit submit and the page is not accepted on the server side (not valid) the dropdowns should be set exactly as when the user clicked the submit button when the page returns to the user. Any suggestions on this?

  • Prevent Cookies From Being Sent on AJAX Request

    - by user340571
    Hello everyone, I have a web service that I invoke from script but that does not need any information stored in cookies. Anytime I make a request to the service, the cookie is sent along with it. I understand that by default cookies are sent with HTTP request, but is there any way at all to overwrite that behavior and not send the cookie? In a nutshell, I am issuing my request like this: $.ajax({ type: "POST", cache: false, url: url, data: data, contentType: "application/json; charset=utf-8", dataType: "json", success: function(response) { successFunc(response); }, error: function(xhr) { errorFunc(xhr); } });

  • Showing div based on filled form field

    - by Fabio
    I have this script where I use a slider to show some elements of a form. So far so good. The way I'm doing it is by having a slider (can't use a multistep form since it uses a plugin not allowing multistep forms, plus some graphic behaviors) and a button that goes to the next slider. So now I need that button (not part of the form) to show only if a certain field is filled. I tried teh following, but it's not working, I assume some error but can't figure what. My code is as follows: $('#clientname').change(function() { var clientVal = $("input").val() == ''; $(".next").hide(); if ($('#clientname').val() != '').show(); else $('.next').hide(); }); and the html as follows: <div class="b40-right"> <h3>The Basics</h3> <div class="label"> Your Name (required)</div> <div class="inputes"> <span class="wpcf7-form-control-wrap your-name"><input id="clientname" type="text" name="your-name" value="" class="wpcf7-form-control wpcf7-text wpcf7-validates-as-required" size="40" /></span> </div> <div class="label">Your Email (required)</div> <div class="inputes"> <span class="wpcf7-form-control-wrap your-email"><input type="text" name="your-email" value="" class="wpcf7-form-control wpcf7-text wpcf7-email wpcf7-validates-as-required wpcf7-validates-as-email" size="40" /></span> </div> <div class="label">Type of Business</div> <div class="inputes"> <span class="wpcf7-form-control-wrap type-of-business"><textarea name="type-of-business" class="wpcf7-form-control wpcf7-textarea" cols="40" rows="10"></textarea></span> </div> </div> <a class="next" href="javascript:stepcarousel.stepBy('mygallery2', 1)"><img id="nextbut1" src="<?php bloginfo('template_directory'); ?>/images/next.png" alt="" /></a> any help on what am I doing wrong? Is there a better approach/solution? (I'm not a programmer as you may figure) Thank you in advance!

  • Randomly Position A Div

    - by Connie
    I'm looking for a way to randomly position a div anywhere on a page (ONCE per load). I'm currently programming a PHP-based fantasy pet simulation game. One of the uncommon items on the game is a "Four Leaf Clover." Currently, users gain "Four Leaf Clovers" through random distribution - but I would like to change that (it's not interactive enough!). What I Am Trying To Do: The idea is to make users search for these "Four Leaf Clovers" by randomly placing this image anywhere on the page: (my rendition of a four leaf clover) I'd like to do this using a Java/Ajax script that generates a div, and then places it anywhere on the page. And does not move it once it's been placed, until the page is reloaded. I've tried so many Google searches, and the closest thing that I've found so far is this (click), from this question. But, removing the .fadein, .delay, and .fadeout stopped the script from working entirely. I'm not by any means a pro with Ajax. Is what I'm trying to do even possible?
