  • Read from values from hidden field values in Jquery?

    - by James123
    Last two nights I am struggle with below code. The problem is I need to remember expanded (or) collapsed toggles sections and on page reload I have show them as is expanded (or) collapsed. $(function() { $('tr.subCategory') .css("cursor", "pointer") .attr("title", "Click to expand/collapse") .click(function() { $(this).siblings('.RegText').toggle(); }); $('tr[@class^=RegText]').hide().children('td'); }) I found small solution in another forum like this. Storing ".subCategory" id values in hidden field in commas-seperated values. In Asp.net page: <input id="myVisibleRows" type="hidden" value="<% response.write(myVisibleRowsSavedValue) %" /> In .js: var idsStr = $(#myVisibleRows).val(); Now My question is: How to store multiple values (.subCategory id) in hidden field when I click on toggle?. also How to parse them back and iterate them get ids and show toggles?. I am very very new to jQuery. Please some one help me out from this.

  • Should I convert data arrays to objects in PHP in a CouchDB/Ajax app?

    - by karlthorwald
    I find myself converting between array and object all the time in PHP application that uses couchDB and Ajax. Of course I am also converting objects to JSON and back (for sometimes couchdb but mostly Ajax), but this is not so much disturbing my workflow. At the present I have php objects that are returned by the CouchDB modules I use and on the other hand I have the old habbit to return arrays like array("error"="not found","data"=$dataObj) from my functions. This leads to a mixed occurence of real php objects and nested arrays and I cast with (object) or (array) if necessary. The worst thing is that I know more or less by heart what a function returns, but not what type (array or object), so I often run into type errors. My plan is now to always cast arrays to objects before returning from a function. Of course this implies a lot of refactoring. Is this the right way to go? What about the conversion overhead? Other ideas or tips?

  • PHP using count() with array

    - by seb
    Hi there, Im trying to get the amount of elements in an array using the count() function, the result is a bit puzzling to me, considere the following example. Assume that the user ID provided is wrong, and therefore had no matches, wouldnt then the result of the count function be 0? yet it is 1. can you explain to me why? thanks $q = mysql_query("select password from users where user_name = '" . $userID . "'"); $check = mysql_fetch_array($q); $result = count($check); echo "RESULT:" . $result;

  • Is it possible to access JSON properties with relative syntax when using JSON defined functions?

    - by Justin Vincent
    // JavaScript JSON var myCode = { message : "Hello World", helloWorld : function() { alert(this.message); } }; myCode.helloWorld(); The above JavaScript code will alert 'undefined'. To make it work for real the code would need to look like the following... (note the literal path to myCode.message) // JavaScript JSON var myCode = { message : "Hello World", helloWorld : function() { alert(myCode.message); } }; myCode.helloWorld(); My question is... if I declare functions using json in this way, is there some "relative" way to get access to myCode.message or is it only possible to do so using the literal namespace path myCode.message?

  • What is an alternative to eval in this situation?

    - by CppLearner
    Many of my view functions do similar things. For the most part, they reverse to a different views upon clicking a button / a text link. So I wrote a helper function render_reverse def render_reverse(f, args): # args are all string type return eval('reverse(' + f + ', ' + args + ')' ) eval is a bad practice, and is pretty slow. It takes 3 seconds to start redirecting, whereas calling reverse directly takes less than 1 second to start redirecting. What alternative do I have? By the way, the function above doesn't work properly. I was modelling after this line (which works) eval('reverse("homepage", args=["abcdefg"])') Thanks.

  • Replacing Text in a Toggled Anchor with JQuery

    - by willmcneilly
    Hi I'm trying to change the text in an anchor on toggle. I'm doing this way at the moment but have found that once the anchor markup has replaced the toggle no longer works. Can someone please explain why this is happening and a solution? Many thanks. $('a#toggleHeader').toggle(function() { $('#header-wrapper').slideUp(); $(this).replaceWith('< href=\"#\" id="toggleHeader">Show Header</>'); //Note:I've move the anchor because I can only post one anchor as a new user },function(){ $('#header-wrapper').slideDown(); $(this).replaceWith('<a href=\"#\" id="toggleHeader">Hide Header</a>'); });

  • Composite pattern in C++ problem

    - by annouk
    Hello! I have to work with an application in C++ similar to a phone book: the class Agenda with an STL list of Contacts.Regarding the contacts hierarchy,there is a base-class named Contact(an abstract one),and the derived classes Friend and Acquaintance(the types of contact). These classes have,for instance, a virtual method called getName,which returns the name of the contact. Now I must implement the Composite pattern by adding another type of contact,Company(being derived from Contact),which also contains a collection of Contacts(an STL list as well),that can be either of the "leaf" type(Friends or Acquaintances),or they can be Companies as well. Therefore,Company is the Compound type. The question is: how and where can I implement an STL find_if to search the contact with a given name(via getName function or suggest me smth else) both among the "leaf"-type Contact and inside the Company collection? In other words,how do I traverse the tree in order to find possible matches there too,using an uniform function definition? I hope I was pretty clear...

  • jquery integrate form parameter in one object

    - by jesse
    There are many forms in my page. I want to merge them in one object and submit them in one object. But I find serializeArray() or serialize() do not match my request, the serializeArray function will generate a array object and serialize is used by get model, it is not an object. is there a jquery or local function can merge them in one object. I have one solution but it is not perfect, loop the array object generated by serializeArray, use $.extend to merge them in one object. is there a better method? kindly help, thanks.

  • Simple Search and Replace use of Regular Expression

    - by nunos
    So, I am adapting some code I found online to suit my needs. However, my set_pixel function has two more parameters. Since there are lots of calls to this function even doing a quick paste over would be very tedious. So, I thought this would be a good time for me to learn some simple regular expressions. So, I have calls of this type: set_pixel(arg1, arg2); which I want to change to something like: set_pixel(arg1, arg2, arg3, arg4); Note: arg1 and and 2 should be preserved, whereas arg3 and arg4 are most of the time the same. How can I achieve this?

  • Jquery .html replacer just empties my selector, what's wrong!?

    - by jphenow
    $("#autoNames").html(function (index, html) { var begin = "<script language='javascript' type='text/javascript'> var names = ["; var end = String('];' + '<' + '/' + 'script' + '>'); var result = begin.concat(jsonService, end); $("#autoNames").html(result); return false; }); I can't figure out for the life of me why this doesn't work. I've gotten the html function to work before, but for some reason this just leaves my autoNames tag empty... and i've called an alert() on the result variable and things exist in that string... any clues? Thanks

  • ASP.NET - How can I cache user details for the duration of their visit?

    - by rockinthesixstring
    I've built a Repository that gets user details Public Function GetUserByOpenID(ByVal openid As String) As User Implements IUserRepository.GetUserByOpenID Dim user = (From u In dc.Users Where u.OpenID = openid Select u).FirstOrDefault Return user End Function And I'd like to be able to pull those details down IF the user is logged in AND IF the cached data is null. What is the best way to create a User object that contains all of the users details, and persist it across the entire site for the duration of their visit? I Was trying this in my Global.asax, but I'm not really happy using Session variables. I'd rather have a single object with all the details inside. Private Sub BaseGlobal_AcquireRequestState(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.AcquireRequestState If Session("UserName") Is Nothing AndAlso User.Identity.IsAuthenticated Then Dim repo As UrbanNow.Core.IUserRepository = New UrbanNow.Core.UserRepository Dim _user As New UrbanNow.Core.User _user = repo.GetUserByOpenID(User.Identity.Name) Session("UserName") = _user.UserName() Session("UserID") = _user.ID End If End Sub

  • Millionth number in the serie 2 3 4 6 9 13 19 28 42 63 ... ?

    - by HH
    It takes about minute to achieve 3000 in my comp but I need to know the millionth number in the serie. The definition is recursive so I cannot see any shortcuts except to calculate everything before the millionth number. How can you fast calculate millionth number in the serie? Serie Def n_{i+1} = \floor{ 3/2 * n_{i} } and n_{0}=2. Interestingly, only one site list the serie according to Goolge: this one. Too slow Bash code #!/bin/bash function serie { n=$( echo "3/2*$n" | bc -l | tr '\n' ' ' | sed -e 's@\\@@g' -e 's@ @@g' ); # bc gives \ at very large numbers, sed-tr for it n=$( echo $n/1 | bc ) #DUMMY FLOOR func } n=2 nth=1 while [ true ]; #$nth -lt 500 ]; do serie $n # n gets new value in the function throught global value echo $nth $n nth=$( echo $nth + 1 | bc ) #n++ done

  • jquery for loop on click image swap

    - by user2939914
    I've created a for loop of images. I would like each image to swap with another image on click individually. Here's the jQuery I've written so far: for ( var i = 1; i < 50; i++) { $('article').append('<div class="ps-block" id="' + i + '"><img src="img/bw/' + i + 'bw.png"></div>'); } $('img').click(function() { var imgid = $(this).attr('id'); $(this).attr("src", "img/color/" + imgid + ".png"); }); I also attempted to use this code inside the for loop after the append, but i ends up returning 50 every time you click since the loop has already ran: $('img[src="img/bw/' + i + 'bw.png"]').click(function() { $(this).attr("src", "img/color/" + this.id + ".png"); }); Thanks!

  • auto_inline - inadequate documentation

    - by Mick
    I want to disable inlining for a particular function. What the compiler does for everything else should be as specified in the project properties. I found a page on a forum which suggested the following: #pragma auto_inline(off) void func() { } #pragma auto_inline() The author suggested that calling auto_inline() with no arguments will set the compiler to revert to doing whatever the default action was before the call to auto_inline(off). Can anyone confirm that this works for visual studio 2008? I ask because the VS2008 documentation makes no mention at all of what happens if you call this function with no arguments.

Code: $(function() { $('#text1').hide(); $('#select2').on('change', function(event) { var opt = this.options[ this.selectedIndex ]; var picked_blue = $(opt).text().match(/Blue/i); if(picked_blue) { $('#text1').show(); } else { $('#text1').hide(); } }); }); But what I also need to add is to display something else if any other item from dropdown menu is selected.

  • Use jQuery to match variable text?

    - by VUELA
    Hello! I have a sidebar navigation that lists blog entry titles down the side of the page. I am trying to write some jquery that will check the text in the title of the current full blog entry page and match it with the corresponding title in the sidebar navigation so that I can apply a class to style for an active state link ... but I'm not quite getting it! Here is the link to an example page: http://ncw-commercial.com/property-listings/eastpoint-plaza-lot.html, and below is my current code. I have also tried using :contains but could not figure out how to get that to work with a variable rather than direct text. $('.single-journal-entry-wrapper .journal-entry .title').each(function(){ var activeTitle = $(this).text(); $(".feedburnerFeedBlock .headline a").filter(function(index) { return $(this).text() == "activeTitle"; }).parent().addClass("activeTitle"); });

  • IE8 is still caching my requests even with mathrandom.

    - by Ozaki
    TLDR IE is still caching my requests even with Math.random() included in the URL. So I added math random onto the end of my url: var MYKMLURL = 'http://' + host + 'data/pattern?key='+ Math.random(); I also added math random onto my function param: window.setTimeout(RefreshPatternData, 1000, MYKMLLAYER); function RefreshPatternData(layer) { layer.loaded = false; layer.setVisibility(true); layer.refresh({ force: true, params: { 'key': Math.random()} }); setTimeout(RefreshPatternData, 30000, MYKMLLAYER); } So the request appears as http://host/data/pattern?key=35678652545 etc. It changes everytime the request is made. It works in Firefox & Chrome & Safari etc. But IE8 is still caching the data and not updating my layer. Any ideas as to why this might be occuring?

  • jQuery animate slidding background image using mouse position wont stop... just keeps going

    I have a neat little jQuery script I am working on. Goal: parent div with overflow hidden holds a larger div with image. When I move the mouse to the left or right of the parent div, the div with image changes margin-left to move left or right. Problem is... if I move the mouse out of the parent div (left or right), the image keeps going. I need the image to stop when the mouse is not on the inside left or right edge of the parent div.
