  • How to simulate a close() in facebox

    - by Bragaadeesh
    Hi, I am using facebox popup in one of my pages. I am having a button in the popup dialog. When I click that button the facebox popup should close (the same way it closes when we press outside the popup). How to do that? Also, I am doing some Ajax stuff when that button is being pressed so I cannot override the onClick event.

  • callback on a variable which is inside a .each() loop

    - by Stoic
    I have this function, which is doing an asynchronous call to FB.api method. Now, i am looping over some data and capturing result of the above method call successfully. However, I am using a .each loop and I really can not figure out how to place my callback in this method, so that the outer method is only executed once. Here are the functions I am using: ask_for_perms($(this).val(),function(result) { $('#some-div').html('<a onclick = "get_perms(result);" >get perms</a>'); }); function ask_for_perms(perms_requested,cb) { var request = []; $.each(perms_requested,function(i,permission) { FB.api({ method: 'users.hasAppPermission', ext_perm: permission }, function(response) { if (response == 0) request.push(permission); request.join(','); cb(request); // cb is called many times here. }); }); } I am trying to return the request string from ask_for_perms function. Can anyone suggest me on where to place a proper callback to ask_for_perms. Right now, however, it works for me, but the callback is being called many times since it is inside a for loop. referencing: returning a variable from the callback of a function

  • Remove class when move to next menu item

    - by danit
    I have a simple nav made up of the following HTML; <div class="inner"> <div class="button"><img class="portal" src="images/portalbutton.png" /></div> <a href="#"><div class="prod_description">&nbsp;</div></a> </div> There are a number of items (All set to float left along side each other) to make up a nav bar. When I hover over .button and/or .prod_description I want the .inner <div> to have the class .hover added to it. This is so I can set a background image around the whole thing (Kind of like highlighting the nav item). I only then want to remove .hover when another .button or .prod_description is hovered over, in which case this nav item takes the .hover class.

  • validation before ajax form submission

    - by ZX12R
    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. Here is what my code looks like <% remote_form_for :customer, :update =>"uxScreenLoaderDiv", :url => {:action => "login", :controller => "site"}, :html => {:id => "uxLoginForm"}, :onsubmit => "validateForm(event)" do |f| %> User name : <%= f.text_field "uxUserName", :class => "TextBox", :style => "width:100px;" %>&nbsp;* &nbsp;Password : <%= f.password_field "uxPassword", :class => "TextBox", :style => "width:100px;" %>&nbsp;* <%= f.submit "Go!", :class => "Button-Simple", :id => "uxSubmitButton" %> <% end %> the javascript function is simple as follows function validateForm(event){ return false; //event.preventDefault(); }

  • Intercept click event on a button, ask for confirmation, then proceed

    - by Blankman
    Based on a variable SomeCondition, I need to intercept a click event on a button, and ask for confirmation, if they say ok, proceed, otherwise ignore click. So something like: if(SomeCondition) { // disable click on button var isOk = window.confirm("Are you sure?"); if(isOk) { $("#button1").click(); } } Note: button1 has already been wired up with a click event via javascript from an external .js file that I can't change. I don't know what the click event was bound too, so I have to disable the click if SomeCondition is true, then ask for confirmation, then continue with the click.

  • Short snippet summarizing a webpage?

    - by Legend
    Is there a clean way of grabbing the first few lines of a given link that summarizes that link? I have seen this being done in some online bookmarking applications but have no clue on how they were implemented. For instance, if I give this link, I should be able to get a summary which is roughly like: I'll admit it, I was intimidated by MapReduce. I'd tried to read explanations of it, but even the wonderful Joel Spolsky left me scratching my head. So I plowed ahead trying to build decent pipelines to process massive amounts of data Nothing complex at first sight but grabbing these is the challenging part. Just the first few lines of the actual post should be fine. Should I just use a raw approach of grabbing the entire html and parsing the meta tags or something fancy like that (which obviously and unfortunately is not generalizable to every link out there) or is there a smarter way to achieve this? Any suggestions? Update: I just found InstaPaper do this but am not sure if it is getting the information from RSS feeds or some other way.

  • How do I make different texts to appear in after clicking x-times?

    - by Sebastian Lindén
    I want to show some text within a class for each click but keep the clicky-class. Shortly, if you click 2 times, you will get a div-text "You clicked two times", you will still be able to click a third time, then you will get "You clicked three times", until the fifth time when everything will hide. Is there any simpel way to do this? I tried with this but couldn't get it to work. var clicks = 0; $('.clicky').on('click', function() { clicks++; if(clicks >= 3) { $(this).add($('.background')).add($('.hello')); } else(clicks >= 5) { $(this).add($('.background')).hide(); } });? http://jsfiddle.net/sLAzY/ This is a working example of the hide function. Hope you understand what I mean Have a nice day!

Is there a simple way to retrieve it?

  • Ideas on limiting content to single printed page?

    - by James Skidmore
    I have 5-6 text areas that users fill out in a template (a couple of columns, basically a newsletter format). I'm needing to limit their content to one printed page, but I'm having a hard time coming up with practical solutions. The printed format (margin, font size, etc.) will be the same for all users, as it's printed from a central source. I've had a couple of ideas, but all of them seem rather unreliable and difficult to implement: Determine height of content using JavaScript and estimate the number of printed pages from that. The problem with this is that browser font sizes can vary, it's only a rough estimate (pixels to inches), etc. Limit the number of characters. This is problematic because there are various text fields, certain characters (like M) take up more space than others (like I), and line breaks obviously count for much more. What ideas do you all have? I appreciate your help!

  • 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 }); });

  • Returning two or more values from a function

    - by cf_PhillipSenn
    I need to return multiple values from a ColdFusion function in an ajax callback function. Here's what I've got: $('input[name="StateName"]').live('change', function() { var StateID = $(this).parents('tr').attr('id'); var StateName = $(this).val(); $.ajax({ url: 'Remote/State.cfc' ,type: "POST" ,data: { 'method': 'UpdateStateName' ,'StateID': StateID ,'StateName': StateName } ,success: function(result){ if (isNaN(result)) { $('#msg').text(result).addClass('err'); } else { $('#' + result + ' input[name="StateName"]').addClass('changed'); }; } ,error: function(msg){ $('#msg').text('Connection error').addClass('err'); } }); }); If I trap a database error, then the success callback is fired, and the result is Not a Number (It is in fact, the text of the error message). I need the function to also pass back other values. One might be the primary key of the row that caused the error. Another might be the old StateName, so that I can refresh the old value on the screen so that the client will know absolutely for sure that their change did not take effect. I guess I'm breaking the rule of atomicity here and need to fix that, because I'm using result as both the primary key of the row that was updated, or it's the error message if the update fails. I need to return both the primary key and the error message.

  • Wait for function to finish before executing the rest

    - by Wurlitzer
    When the user refreshes the page, defaultView() is called, which loads some UI elements. $.address.change() should execute when defaultView() has finished, but this doesn't happen all the time. $.address.change() cannot be in the success: callback, as it's used by the application to track URL changes. defaultView(); function defaultView() { $('#tout').fadeOut('normal', function() { $.ajax({ url: "functions.php", type: "GET", data: "defaultview=true", async: false, success: function (response) { $('#tout').html(response).fadeIn('normal'); } }); }); } $.address.change(function(hash) { hash = hash.value; getPage(hash); }); I'm at a loss as to how to make $.address.change() wait for defaultView() to finish. Any help would be appreciated.

  • how to .call() on the unnamed function in javascript?

    - by Anonymous
    Let's suppose I have button #click, And suppose I bind the on click event as follows: $('#click').click(function(){ alert('own you'+'whatever'+$(this).attr('href')); }); But I want this to refer to some other element, let's say #ahref. If it was a named function I would simply refer it by name: foo.call('#ahref'); How could I use .call() though, if the function is called inline and does not have a name?
