  • button onclick not working

    - by nsw1475
    I have a javascript where I need to hide (and eventually show) some text by clicking a button. However, when I click the button, it does not call the function specified in the onclick parameter, and so nothing happens. Here is my source code: <script type="text/javascript"> $(document).ready(function(){ var tip = 1; $(".tip1").hide(); $(".tip2").hide(); switch (tip) { case 1: $(".tip1").show(); break; case 2: $(".tip2").show(); break; } function nextTip() { $(".tip1").hide(); return; } }); </script> <br/> <div id='bg_container' style='background-image: url("<?=$PICS?>trackingpage_middle.jpg")' > <img style='z-index:-1;' width='737px' src='<?=$PICS?>trackingpage_top.jpg'> <div id='main_container' > <form> <input type="button" onClick="nextTip()" value = "Next Tip" /> </form> <div class="tip1"> ... and so on.

    - by Nik
    I have worked out how to fade an element in: Click here to view the page If you click on the heading Posture 1 : Standing Deep Breathing : you will notice the element fades in as it should. If you now click on posture 2 you will see the element fades in below posture 1. I need to be able to swap posture 1 with posture 2. I have a total of 26 postures that all have images that need to fade in and then be swapped with another image when another heading is clicked. $(document).ready(function(){ $('#section_Q_01,#section_Q_02').hide(); $('h5.trigger#Q_01').click(function(){ $('#section_Q_01').fadeIn(2000) ; }); $('h5.trigger#Q_02').click(function(){ $('#section_Q_02').fadeIn(5000) ; }); }); and the html <div id="section_Q_01" class="01"> <div class="pics"> <img src="../images/multi/poses/pose1/Pranayama._01.jpg"/> <img src="../images/multi/poses/pose1/Pranayama._02.jpg"/> <img src="../images/multi/poses/pose1/Pranayama._03.jpg"/> </div> </div> <div id="section_Q_02" class="02"> <div class="pics"> <img src="../images/multi/poses/pose2/Half_Moon_Pose_04.jpg" /> <img src="../images/multi/poses/pose2/Backward_Bending_05.jpg" /> <img src="../images/multi/poses/pose2/Hands_to_Feet_Pose_06.jpg" /> </div> </div> I need to be able to swap a total of 26 elements #section_Q_01 - #section_Q_26 Any help appreciated

  • python recursive iteration exceeding limit for tree implementation

    - by user3698027
    I'm implementing a tree dynamically in python. I have defined a class like this... class nodeobject(): def __init__(self,presentnode=None,parent=None): self.currentNode = presentnode self.parentNode = parent self.childs = [] I have a function which gets possible childs for every node from a pool def findchildren(node, childs): # No need to write the whole function on how it gets childs Now I have a recursive function that starts with the head node (no parent) and moves down the chain recursively for every node (base case being the last node having no children) def tree(dad,children): for child in children: childobject = nodeobject(child,dad) dad.childs.append(childobject) newchilds = findchildren(child, children) if len(newchilds) == 0: lastchild = nodeobject(newchilds,childobject) childobject.childs.append(lastchild) loopchild = copy.deepcopy(lastchild) while loopchild.parentNode != None: print "last child" else: tree(childobject,newchilds) The tree formation works for certain number of inputs only. Once the pool gets bigger, it results into "MAXIMUM RECURSION DEPTH EXCEEDED" I have tried setting the recursion limit with set.recursionlimit() and it doesn't work. THe program crashes. I want to implement a stack for recursion, can someone please help, I have gone no where even after trying for a long time ?? Also, is there any other way to fix this other than stack ?

  • How to use clearInterval() and then make changes to the DOM?

    - by George D.
    I have this code and the problem I have is that I want to stop the loop and then replace the text 'Done!' that comes from the sms-loader.php script with the "textnew" string. Problem is that the loop occurs one more time so the text in the div.checkstatus field is again replaced by the calling php script. The strange thing is that I see the log message and again I get a new (and final) request, although the ordering is the opposite (first stop then replace text()) in my script. I need to understand why this is happening. $(document).ready(function() { var interval = ""; $('.checkstatus').each(function(){ var msgid = $(this).data('msg') $this = $(this), hid = $this.data('history'), textnew = '<a href="sms-dstatus.php?id='+msgid+'&sid=' +hid+ '&amp;keepThis=true&amp;TB_iframe=true&amp;height=430&amp;width=770" title="Delivery Status" class="thickbox"><img src="../template/icons/supermini/chart_curve.png" alt="status" width="16" height="16" /></a>'; interval = setInterval(function() { $this.load('../pages/sms-loader.php?id='+msgid); // stop the loop if($this.text()=='Done!'){ // stop it clearInterval(interval); console.log(textnew); this.html(textnew); /// this line is the problem } }, 5000); // 5 secs }); });

  • Manipulating original elements with qTip

    - by pjotr
    I have a bunch of divs on my page and each of them has only the class attribute. In the divs there are some spans, which are set up to display a tooltip with the help of qTip. The tooltip should contain three items: Up: anchor, which should move the OuterDiv up (probably something like this: move up/down in jquery) Down: anchor, which should move the OuterDiv down Delete: anchor, which should remove the calling OuterDiv My code so far: <body> <div class="OuterDiv"> <div class="InnerDiv"> <span class="Position">Position 1</span> </div> </div> <div class="OuterDiv"> <div class="InnerDiv"> <span class="Position">Position 2</span> </div> </div> </body> And scripts: $(document).ready(function () { var qTipContent = '<a href="javascript:void(0)" onclick="">&uarr;</a>&nbsp;&nbsp;&nbsp;'; qTipContent = qTipContent + '<a href="javascript:void(0)" onclick="">&darr;</a>&nbsp;&nbsp;&nbsp;'; qTipContent = qTipContent + '<a href="javascript:void(0)" onclick="">X</a>'; $('.Position').each(function () { $(this).qtip({ content: qTipContent, hide: { fixed: true } }) }); }); How should the onclick function in the qTip content look like?

  • Strange compiler complaint when using similar code

    - by Jason
    For a project, I have to ask the user for a file name, and I'm reading it in character by character using getchar. From the main, I call the function char *coursename= introPrint(); //start off to print the usage directions and get the first bit of input. That function is defined as char *introPrint(){ int size= 20; int c; int length=0; char buffer[size]; //instructions printout, cut for brevity //get coursename from user and return it while ( (c=getchar()) != EOF && (c != '\n') ){ buffer[length++]= c; if (length==size-1) break; } buffer[length]=0; return buffer; } This is basically identical code I wrote to ask the user for input, replace the character echo with asterisks, then print out the results. Here, though, I'm getting a function returns address of local variable warning for the return statement. So why am I getting no warnings from the other program, but trigger one for this code?

  • Pipelining String in Powershell

    - by ChvyVele
    I'm trying to make a simple PowerShell function to have a Linux-style ssh command. Such as: ssh username@url I'm using plink to do this, and this is the function I have written: function ssh { param($usernameAndServer) $myArray = $usernameAndServer.Split("@") $myArray[0] | C:\plink.exe -ssh $myArray[1] } If entered correctly by the user, $myArray[0] is the username and $myArray[1] is the URL. Thus, it connects to the URL and when you're prompted for a username, the username is streamed in using the pipeline. Everything works perfectly, except the pipeline keeps feeding the username ($myArray[0]) and it is entered as the password over and over. Example: PS C:\Users\Mike> ssh xxxxx@yyyyy login as: xxxxx@yyyyy's password: Access denied xxxxx@yyyyy's password: Access denied xxxxx@yyyyy's password: Access denied xxxxx@yyyyy's password: Access denied xxxxx@yyyy's password: Access denied xxxxx@yyyyy's password: FATAL ERROR: Server sent disconnect message type 2 (protocol error): "Too many authentication failures for xxxxx" Where the username has been substituted with xxxxx and the URL has been substituted with yyyyy. Basically, I need to find out how to stop the script from piping in the username ($myArray[0]) after it has been entered once. Any ideas? I've looked all over the internet for a solution and haven't found anything.

  • How can I post an array of string to ASP.NET MVC Controller without a form?

    - by rodbv
    Hi there, I am creating a small app to teach myself ASP.NET MVC and JQuery, and one of the pages is a list of items in which some can be selected. Then I would like to press a button and send a List (or something equivalent) to my controller containing the ids of the items that were selected, using JQuery's Post function. I managed to get an array with the ids of the elements that were selected, and now I want to post that. One way I could do this is to have a dummy form in my page, with a hidden value, and then set the hidden value with the selected items, and post that form; this looks crufty, though. Is there a cleaner way to achieve this, by sending the array directly to the controller? I've tried a few different things but it looks like the controller can't map the data it's receiving. Here's the code so far: function generateList(selectedValues) { var s = { values: selectedValues //selectedValues is an array of string }; $.post("/Home/GenerateList", $.toJSON(s), function() { alert("back") }, "json"); } And then my Controller looks like this public ActionResult GenerateList(List<string> values) { //do something } All I managed to get is a "null" in the controller parameter... Any tips?

  • Display a summary of form element values before submit

    - by Dirty Bird Design
    Using jquery formtowizard.js with an ajax submit. I want the last step of the form to display a summary of all form fields that were filled out. I can get it to work in isolated test cases, but not in full use. Form <form id="Commission" method="post" action="PHP/CommissionsSubmit.php"> <fieldset id="Initial"> <legend>Enter Your Information</legend> <ul> <li> <label for="FName">First Name*</label><input type="text" name="FName" id="FName"> </li> //repeat many li's </ul> </fieldset> <fieldset> <legend>Second Step</legend> //more li's </fieldset> <fieldset> <legend>Confirmation</legend> <span id="CFName"></span> </fieldset> </form> the jquery to get "#CFName" value $('#FName').keyup(function() { $('#CFName').val($(this).val()); }); I can't get the value to appear in the span "#CFName"... Could this have to do with the "serialize" function or anything going on with my $ajax submit function? its happening before submit... Please help! I apologize, but I've gone back and forth with "#CFName" being a span and an input, using .val and .html respectively

  • Why is textbox.focus throwing the lostfocus event?

    - by cost
    I've seen a few similar questions on SO but nothing that seems to actually address the issue. Here's a simplified version of the function. Private Sub Check_Quantity(sender As System.Object, e As System.Windows.RoutedEventArgs) _ Handles textbox_quantity.LostFocus Dim worked As Boolean = Integer.TryParse(textbox_quantity.Text, quantity) If Not worked Then MsgBox("Enter a valid number for the quantity") textbox_quantity.Focus() textbox_quantity.SelectAll() quantity = 0 End If End Sub It's important to note that this is WPF. What I want to do is very simple. When someone finishes with the textbox the program checks that what they entered is a number. If it does it sticks this in an integer. If not, it tells them to fix it and keeps the focus on the textbox. The issue is a few things, but what it comes down to is this function runs in an infinite loop. This same function works fine in WinForms, but not in WPF. On some other questions people have said that the messagebox appearing causes focus to be lost, but in testing this isn't true. It still loops regardless of if the messagebox is called or not. The problem is the call to textbox_quantity.Focus(). Without that it works fine. Regardless of whether it's there or not though, focus is not set to the textbox, though textbox_quantity.Focus() still returns a value of true. Any thought of what's going on and maybe how I could fix it?

  • validation before ajax form submission

    How do i introduce validation before remote_form_for submits? I have javascript function called validateForm(). I am able to call it before the AJAX request process. I tried to use return false and event.preventDefault. But there seems to be no effect.

  • jquery ui dialog open multiple dialog boxes using the same class on the button and the content div

    - by MichaelAntoni
    Hello there, i want to open multiple dialog boxes by using the same class on both the button and the content div. The below works but only for the first time. jQuery('.helpDialog').hide(); jQuery('.helpButton').click(function() { jQuery(this).next('.helpDialog').dialog({ autoOpen: true, title: 'Help', width: 500, height: 300, position: [180,10], draggable: true, resizable: false, modal: false }); return false; }); we know the reason for this http://blog.nemikor.com/2009/04/08/basic-usage-of-the-jquery-ui-dialog/ "the second call is ignored because the dialog has already been instantiated on that element." But when i fix that problem by trying the code below, the dialog box no longer opens. Can anyone help? Thanks in advance jQuery('.helpDialog').hide(); jQuery(function() { jQuery('.helpDialog').dialog({ autoOpen: false, modal: true, title: 'Info', width: 600, height: 400, position: [200,0], draggable: false }); }); jQuery('.helpButton').click(function() { jQuery(this).next('.helpDialog').dialog('open'); return false; });

  • How can I run some common code from both (a) scheduled via Windows Task & (b) manually from within W

    - by Greg
    Hi, QUESTION - How can I run some common code from both (a) scheduled via Windows Task & (b) manually from within WinForms app? BACKGROUND: This follows on from the http://stackoverflow.com/questions/2489999/how-can-i-schedule-tasks-in-a-winforms-app thread REQUIREMENTS C# .NETv3.5 project using VS2008 There is an existing function which I want to run both (a) manually from within the WinForms application, and (b) scheduled via Windows Task. APPROACHES So what I'm trying to understand is what options are there to make this work eg Is it possible for a windows task to trigger a function to run within a running/existing WinForms application? (doesn't sound solid I guess) Split code out into two projects and duplicate for both console application that the task manager would run AND code that the winforms app would run Create a common library and re-use this for both the above-mentioned projects in the bullet above Create a service with an interface that both the task manager can access plus the winforms app can manage Actually each of these approaches sounds quite messy/complex - would be really nice to drop back to have the code only once within the one project in VS2008, the only reason I ask about this is I need to have a scheduling function and the suggestion has been to use http://taskscheduler.codeplex.com/ as the means to do this, which takes the scheduling out of my VS2008 project... thanks

  • Flex/Flash: Don't show 'bar' cursor when dragging over a TextField/TextArea?

    - by David Wolever
    As the title suggests, how can I prevent the "bar" cursor from appearing when I click-and-drag over a TextField? For example, consider this interaction: I'd like to prevent the cursor changing to the "bar" in step "2". How can I do that? I've tried fiddling with the selectable flag: protected static function fixMouseOverAfordance(field:TextField):void { var iOwnClick:Boolean = false; function handleMouseOver(event:MouseEvent):void { if (event.buttonDown) { field.selectable = iOwnClick; } else { field.selectable = true; iOwnClick = false; } } field.addEventListener(MouseEvent.MOUSE_OVER, handleMouseOver, false, EventPriority.CURSOR_MANAGEMENT+1); field.addEventListener(MouseEvent.ROLL_OVER, handleMouseOver, false, EventPriority.CURSOR_MANAGEMENT+1); field.addEventListener(MouseEvent.MOUSE_MOVE, handleMouseOver, false, EventPriority.CURSOR_MANAGEMENT+1); field.addEventListener(MouseEvent.MOUSE_DOWN, function(event:MouseEvent):void { iOwnClick = true; field.selectable = true; }); } But the "bar" cursor still appears the first time the mouse is moved over the text field (however, after it has been moved out then moved back in, it does the right thing).

  • how to solve a weired swig python c++ interfacing type error

  • Where to add an overloaded operator for the tr1::array?

    - by phlipsy
    Since I need to add an operator& for the std::tr1::array<bool, N> I wrote the following lines template<std::size_t N> std::tr1::array<bool, N> operator& (const std::tr1::array<bool, N>& a, const std::tr1::array<bool, N>& b) { std::tr1::array<bool, N> result; std::transform(a.begin(), a.end(), b.begin(), result.begin(), std::logical_and<bool>()); return result; } Now I don't know in which namespace I've to put this function. I considered the std namespace as a restricted area. Only total specialization and overloaded function templates are allowed to be added by the user. Putting it into the global namespace isn't "allowed" either in order to prevent pollution of the global namespace and clashes with other declarations. And finally putting this function into the namespace of the project doesn't work since the compiler won't find it there. What had I best do? I don't want to write a new array class putted into the project namespace. Because in this case the compiler would find the right namespace via argument dependent name lookup. Or is this the only possible way because writing a new operator for existing classes means extending their interfaces and this isn't allowed either for standard classes?

  • Alert and if changes behaviour dom copying

    - by lowkey
    Hi guys! Tried to make a little old school ajax (iframe-javascript) script. A bit of mootools is used for DOM navigation Description: HTML: 1 iframe called "buffer" 1 div called "display" JAVASCRIPT: (short: copy iframe content into a div on the page) 1) onLoad on iframe triggers handler(), a counter makes sure it only run once (this is because otherwise firefox will go into feedback loop. What i think happens: iframe on load handler() copyBuffer change src of iframe , and firefox takes that as an onload again) 2) copybuffer() is called, it sets src of iframe then copies iframe content into div, then erases iframe content THE CODE: count=0; function handler(){ if (count==0){ copyBuffer(); count++; } } function copyBuffer(){ $('buffer').set('src','http://www.somelink.com/'); if (window.frames['buffer'] && $('display') ) { $('display').innerHTML = window.frames['buffer'].document.body.innerHTML; window.frames['buffer'].document.body.innerHTML=""; } } problems: QUESTION 1) nothing happens, the content is not loaded into the div. But if i either: A) remove the counter and let the script run in a feedback loop: the content is suddenly copied into the div, but off course there is a feedback loop going on, you can see it keeps loading in the status bar. OR B) insert an alert in the copyBuffer function. The content is copied, without the feedback loop. why does this happen? QUESTION 2) The If wrapped around the copying code i got from a source on the internet. I am not sure what it does? If i remove it the code does not work in: Safari and Chrome. Many thanks in advance!

  • Jquery ajax ($.ajax) not working on chrome. please help

    - by racky
    Hi, I need a little help to figure out why the following code does not work on google chrome 5/windows xp. It works well on all other browsers (IE, FF, Safri, Opera etc). Can someone shed some light around this? /* AJAX Request */ jq("#a-post-request").unbind("click").bind("click", function(e){ //jq("#loading").css({"display":"block"}); jq.ajax({ url: "search_data_table.html", type: "get", cache: false, error: function(){alert ("No data found for your search.");}, success: function(data){ jq("#search-results-table tbody").empty().append(data); jq("#search-results").css({"display":"block"}); jq("#search-results-table").trigger("update"); // this one is for the table sorter plugin // set sorting column and direction, this will sort on the first column. var sorting = [[0,0]];// this one is for the table sorter plugin // sort on the first column . jq("#search-results-table").trigger("sorton",[sorting]);// this one is for the table sorter plugin e.preventDefault(); } }); }); Many thanks, Racky
