  • jQuery: resizing element cuts off parent's background

    - by Justine
    Hi, I've been trying to recreate an effect from this tutorial: http://jqueryfordesigners.com/jquery-look-tim-van-damme/ Unfortunately, I want a background image underneath and because of the resize going on in JavaScript, it gets resized and cut off as well, like so: http://dev.gentlecode.net/dotme/index-sample.html - you can view source there to check the HTML, but basic structure looks like this: <div class="page"> <div class="container"> div.header ul.nav div.main </div> </div> Here is my jQuery code: $('ul.nav').each(function() { var $links = $(this).find('a'), panelIds = $links.map(function() { return this.hash; }).get().join(","), $panels = $(panelIds), $panelWrapper = $panels.filter(':first').parent(), delay = 500; $panels.hide(); $links.click(function() { var $link = $(this), link = (this); if ($link.is('.current')) { return; } $links.removeClass('current'); $link.addClass('current'); $panels.animate({ opacity : 0 }, delay); $panelWrapper.animate({ height: 0 }, delay, function() { var height = $panels.hide().filter(link.hash).show().css('opacity', 1).outerHeight(); $panelWrapper.animate({ height: height }, delay); }); }); var showtab = window.location.hash ? '[hash=' + window.location.hash + ']' : ':first'; $links.filter(showtab).click(); }); In this example, panelWrapper is a div.main and it gets resized to fit the content of tabs. The background is applied to the div.page but because its child is getting resized, it resizes as well, cutting off the background image. It's hard to explain so please look at the link above to see what I mean. I guess what I'm trying to ask is: is there a way to resize an element without resizing its parent? I tried setting height and min-height of .page to 100% and 101% but that didn't work. I tried making the background image fixed, but nada. It also happens if I add the background to the body or even html. Help?

    - by Gandalf StormCrow
    I'm trying to create this slider http://jqueryui.com/demos/slider/#rangemax Is it possible to parametrize the max value? For ex: $("#slider-range-max").slider({ range: "max", min: 1, max: maxValue, value: 2, slide: function(event, ui) { $("#amount").val(ui.value); } }); Is it possible to pass maxValue value, when I click on something? After its been initialized? Not on document ready function, but even after that?

  • What/Where are the Naming Rules for Controller actions in a Zend_Application App

    - by Alan Storm
    I've created a Zend_Application using the zf tool that's bundled with Zend Framework (1.96, if that matters) What at the rules for formatting action names and how those action names get translated into into URL paths, and where in the Framework codebase does this happen? I ask because I tried to create an action like public function createFooAction() { } and it wouldn't load with a URL like http://example.com/controller/createFoo BUT, the following did work public function createfooAction() { } http://example.com/controller/createfoo I also know non-alphanumeric characters get treated differently, and I'd like to know the base rules I'm dealing with.

  • Continuous Form, how to add/update records with external connection

    - by Mohgeroth
    EDIT After some more research I found that I cannot use a continuous form with an unbound form since it can only reference a single record at a time. Given that I've altered my question... I have a sample form that pulls out data to enter into a table as an intermediary. Initially the form is unbound and I open connections to two main recordsets. I set the listbox's recordset equal to one of them and the forms recordset equal to the other. The problem is that I cannot add records or update existing ones. Attempting to key into the fields does nothing almost as if the field was locked (Which it is not). Settings of the recordsets are OpenKeyset and LockPessimistic. Tables are not linked, they come from an outside access database seperate from this project and must remain that way. I am using an adodb connection to get the data. Could the separation of the data from the project be causing this? Sample Code from the Form Option Compare Database Option Explicit Private conn As CRobbers_Connections Private exception As CError_Trapping Private mClient_Translations As ADODB.Recordset Private mUnmatched_Clients As ADODB.Recordset Private mExcluded_Clients As ADODB.Recordset //Construction Private Sub Form_Open(Cancel As Integer) Set conn = New CRobbers_Connections Set exception = New CError_Trapping Set mClient_Translations = New ADODB.Recordset Set mUnmatched_Clients = New ADODB.Recordset Set mExcluded_Clients = New ADODB.Recordset mClient_Translations.Open "SELECT * FROM Client_Translation" _ , conn.RBRS_Conn, adOpenKeyset, adLockPessimistic mUnmatched_Clients.Open "SELECT DISTINCT(a.Client) as Client" _ & " FROM Master_Projections a " _ & " WHERE Client NOT IN ( " _ & " SELECT DISTINCT ClientID " _ & " FROM Client_Translation);" _ , conn.RBRS_Conn, adOpenKeyset, adLockPessimistic mExcluded_Clients.Open "SELECT * FROM Clients_Excluded" _ , conn.RBRS_Conn, adOpenKeyset, adLockPessimistic End Sub //Add new record to the client translations Private Sub cmdAddNew_Click() If lstUnconfirmed <> "" Then AddRecord End If End Sub Private Function AddRecord() With mClient_Translations .AddNew .Fields("ClientID") = Me.lstUnconfirmed .Fields("ClientAbbr") = Me.txtTmpShort .Fields("ClientName") = Me.txtTmpLong .Update End With UpdateRecords End Function Private Function UpdateRecords() Me.lstUnconfirmed.Requery End Function //Load events (After construction) Private Sub Form_Load() Set lstUnconfirmed.Recordset = mUnmatched_Clients //Link recordset into listbox Set Me.Recordset = mClient_Translations End Sub //Destruction method Private Sub Form_Close() Set conn = Nothing Set exception = Nothing Set lstUnconfirmed.Recordset = Nothing Set Me.Recordset = Nothing Set mUnmatched_Clients = Nothing Set mExcluded_Clients = Nothing Set mClient_Translations = Nothing End Sub

  • How do make my encryption algorithm encrypt more than 128 bits?

    - by Ranhiru
    OK, now I have coded for an implementation of AES-128 :) It is working fine. It takes in 128 bits, encrypts and returns 128 bits So how do i enhance my function so that it can handle more than 128 bits? How do i make the encryption algorithm handle larger strings? Can the same algorithm be used to encrypt files? :) The function definition is public byte[] Cipher(byte[] input) { }

  • Cepstral Analysis for pitch detection

    - by Ohmu
    Hi! I'm looking to extract pitches from a sound signal. Someone on IRC just explain to me how taking a double FFT achieves this. Specifically: take FFT take log of square of absolute value (can be done with lookup table) take another FFT take absolute value I am attempting this using vDSP I can't understand how I didn't come across this technique earlier. I did a lot of hunting and asking questions; several weeks worth. More to the point, I can't understand why I didn't think of it. I am attempting to achieve this with vDSP library. it looks as though it has functions to handle all of these tasks. However, I'm wondering about the accuracy of the final result. I have previously used a technique which scours the frequency bins of a single FFT for local maxima. when it encounters one, it uses a cunning technique (the change in phase since the last FFT) to more accurately place the actual peak within the bin. I am worried that this precision will be lost with this technique I'm presenting here. I guess the technique could be used after the second FFT to get the fundamental accurately. But it kind of looks like the information is lost in step 2. as this is a potentially tricky process, could someone with some experience just look over what I'm doing and check it for sanity? also, I've heard there is an alternative technique involving fitting a quadratic over neighbouring bins. Is this of comparable accuracy? if so, I would favour it, as it doesn't involve remembering bin phases. so questions: does this approach makes sense? Can it be improved? I'm a bit worried about And the log square component; there seems to be a vDSP function to do exactly that: vDSP_vdbcon however, there is no indication it precalculates a log-table -- I assume it doesn't, as the FFT function requires an explicit pre-calculation function to be called and passed into it. and this function doesn't. Is there some danger of harmonics being picked up? is there any cunning way of making vDSP pull out the maxima, biggest first? Can anyone point me towards some research or literature on this technique? the main question: is it accurate enough? Can the accuracy be improved? I have just been told by an expert that the accuracy IS INDEED not sufficient. Is this the end of the line? Pi PS I get SO annoyed (npi) when I want to create tags, but cannot. :| I have suggested to the maintainers that SO keep track of attempted tags, but I'm sure I was ignored. we need tags for vDSP, accelerate framework, cepstral analysis

  • Open link in new window with Jquery

    - by mtwallet
    Hi. I am trying to open a few links in a new window using Jquery rather than _blank so my html remains valid. My code looks like this: $(document).ready(function() { $('a[id="external-url"]').click(function(){ $(this).attr('target','_blank'); }); }); This works just fine except when the link is contained within html I have placed on the page using the Jquery load() method. Can anyone explain why and please help with a solution?

  • dijit/form/Select broken in Internet Explorer using Esri Javascript 3.7

    - by disuse
    After developing a web map app in Firefox, I tested my code in Internet Explorer (company standard) to discover that the dijit/form/Select is misbehaving using the latest Esri JavaScript v3.7. The issue I am seeing is that the Select will not update/change from the first option in the list when using v3.7. If I bump the version down to 3.6, it works as expected. I've tried IE browser modes from 7 to 10 and am experiencing the same behavior between all of them. Can someone confirm they are experiencing the same thing? Example in 3.7 - http://jsbin.com/aVIsApO/1/edit Example in 3.6 - http://jsbin.com/odIxETu/7/edit Codeblock var url = "http://services.arcgis.com/V6ZHFr6zdgNZuVG0/ArcGIS/rest/services/Street_Trees/FeatureServer/0"; var frmTrees; require([ "esri/tasks/query", "esri/tasks/QueryTask", "dojo/dom-construct", "dijit/form/Select", "dojo/parser", "dijit/registry", "dojo/on", "dojo/ready", "dojo/_base/connect", "dojo/domReady!" ], function( Query, QueryTask, domConstruct, Select, parser, registry, on, ready, connect ) { ready(function() { frmTrees = registry.byId("trees"); var qt = new QueryTask(url); var query = new Query(); query.where = "FID < 25"; query.orderByFields = ["qSpecies"]; query.returnGeometry = false; query.outFields = ["qSpecies", "TreeID"]; query.groupByFieldsForStatistics = ["qSpecies"]; //query.returnDistinctValues = true; qt.execute(query, function(results) { //var frm_domain_area = dom.byId("domain_area"); var testVals = {}; for (var i = 0; i < results.features.length; i++) { var id = results.features[i].attributes.TreeID; var desc = results.features[i].attributes.qSpecies; if (!testVals[id]) { testVals[id] = true; var selectElem = domConstruct.create("option",{ label: desc + " (" + id + ")", value: id }); frmTrees.addOption(selectElem); } } }); frmTrees.on("change", function() { console.debug(frmTrees.get("value")); }); }); });
