  • jQuery : how to determine that a div is scrolled down

    - by subtenante
    I have a div with defined height, and overflow:scroll;. Its content is too long so scrollbars appear. Now for the ichy part. Some of its inner HTML strangely appears all the time (to be precise, the footer of a table generated by the tableFilter plugin). I'd like to make this footer disappear when it is not needed (it actually appears out of the containing <div>'s border). I resolved to make it disappear but setting its z-index to -1000. But I want to make it appear when the containing <div> is totally scrolled down. How can I know the user has scrolled at the bottom ? Using the help from answers below, I used scrollTop attribute but the difference between scrollTop and innerHeight is the size of the scrollbar plus some unidentified delta. A scrollbar is 16 pixels high in most browsers under Windows, but I get a difference of 17 in Firefox and something like 20 in IE, where my <div> content's borders seems to be rendered bigger. A way (actually two ways...) to compute the scrollbar size has been given there.

  • Clearing a default value in a search box with jQuery

    - by james6848
    Hi, Can't seem to achieve this simple functionality! All I want is to clear a default search term in an input box when it is clicked. The following works up to a point but clears any other text entered, I would've thought resetting search_form_text should have solved this: search_form_text = $('#block-search-0 #edit-search-block-form-l').attr('value'); if (search_form_text == 'Enter search keywords here') { $('#block-search-0 #edit-search-block-form-l').click(function() { $('#block-search-0 #edit-search-block-form-l').attr('value', ''); search_form_text = ''; }); } Hmmmm... :)

  • Set the mouseover Attribute of a div using JQuery

    - by Abs
    Hello all, I would like to set an attribute for a div. I have done this: $('#row-img_1').onmouseover = function (){ alert('foo'); }; $('#row-img_2').onmouseout = function (){ alert('foo2'); }; However, the above has not worked, it does not alert when mouse is over or when it moves out. I have also tried the $('#row-img_1').attr(); and I could not get this to work either. I am aware that I should be using a more effective event handling system but my divs are dynamically generated. Plus this is a small project. ;) Thanks all for any help.

  • jQuery Syntax Question, pretty easy I think..

    - by Fuego DeBassi
    Hi all, question: <script type="text/javascript"> $(document).ready(function() { $(".module .caption").hide(); $(".module").hover(function() { $(this).find(".caption").slideDown(); },function() { $(this).find(".caption").slideUp(); }); }); </script> This snippet works great for my purposes, the only caveat is that I need the .module hover function to simultaneously add a class of "under" to all other ".caption"'s that are not $this, and then remove them when the hover ends. So basically I don't want the "module" that is hovered to get the class, I want it to do exactly what I am showing here...sliding .caption up and down on end hover, I just want all other ".caption"s to get the under class when any ".module" is hovered. Just hitting a dead end with what I have been trying, want to do it in the same function. Any ideas?

Am I doing something wrong? The PHP file does give me data when testing it directly.

  • Jquery JSON .each() doesnt work in Google Chrome

    - by Sheriffen
    I have a really simple chat application on a site which works pretty good. It requests by ajax like this: $.ajax({ url: "fetch/"+CHAT_SESSION_ID+"/"+LAST_MESSAGE_ID, dataType: "json", cache: false, success: function(data) { if (data.session_active == 0) { //If other chatter ended session alert("Session Ended"); } else { $.each(data.messages, function(i,msg){ alert(msg.message.Body); )}; } } }); and gets a json response that lookes like this: { "session_active": "1", "messages": [ {"message": {"MsgID": "100", "UserID": "1", "Body": "heyy"}}, ]} It works really well in at least FF and Saf but in Chrome it never gets past the .each! This is driving me nuts, have tried everything I've come across online for days but I can't seem to get it right. Please someone help! I can provide testserver if someone wants to firebug it themselves ;)

  • Calculate a div's height with jQuery - minus header and footer

    - by Dirty Bird Design
    I'm using a sticky footer (negative margin solution) and it works fine. What I need to do is calculate the window's height, subtract the known height of the header and footer then apply that number and use it for the height of the main wrapper div. CSS solutions cause other issues, is there a good way to do this? var h = window.height(); var k = 300; //header is 100px footer is 200px $('#wrap').height(h-k); rough idea, pls help.

    - by mike
    Hi, I'm trying to use next() to toggle a div. The problem is that the "trigger" is in a different div than the one I want to toggle. An example that works: $("span.trigger").click(function(){ $(this).next("div.task_description").slideToggle("fast"); }); <span class="trigger">The trigger</span> <div class="task_description "> some content </div> But the way I need the html setup is: <div> <span class="trigger">The trigger</span> </div> <div class="task_description "> some content </div> That doesn't work... any suggestions?

  • jquery + prepend text not working

    - by Tiago Teixeira
    Hello, I have this following code: $(".preview").find("#panel").each(function(i, val) { var x = "" + $(val).html(); $(x).find(".dmPageHeadline").prepend(" 1 - "); console.log($(x).html()); html += $(x).html(); }); This code iterates through all accordion panels, concatenates its content and add " 1 - " to the header ( class "dmPageHeadline" ). Probably it's a simple detail, but i cannot figure it out... this line $(x).find(".dmPageHeadline").prepend(" 1 - "); doesn't preprend the desired text. Anyone can point me out what is wrong here? Thank you very much and happy new year ! Teixeira

  • jQuery: I need something like ':visible' that works even if the parent is display=none

    - by Master Morality
    I have a list where elements are hidden for multiple reasons, each corresponding to a css class i.e: <style> .filteredOut { display: none; } .somethingElse { display : none; } ... </style> I want to apply alternating css classes via .filter(':even').addClass('even') but only to classes that are visible. The problem is that the parent is hidden when this happens so .filter(':visible') returns 0 elements. I need something like .filter(':visibileEventIfParentIsNot') Further more, I'd rather not have to call a function with this in it every time I call a function that changes what's visible in a list. This may be a pipe dream, but is there a way to do this ala live() or something similar? I'm open to off the wall ideas.

  • jQuery - Set min-height of div

    - by Kenny Bones
    This is probably really easy for most of you. But I'm in need of a small snippet that looks up the current height of a div (the div has a dynamic height based on the content inside it) and then set that value in the css class's min-height value. Basically what this means is that I want this container to have it's min-height to be the exact same value as it's current height. This is probably a quick one :)

  • Dynamic change of class of <TR> with Jquery

    - by Coronier
    Hi all, This is my first post, and first please forgive me for my poor english. I have a problem I really can't fix: I have a <table> of questions, the first question is visible (class:visible), the others are hidden (class:hidden) $(document).ready(function(){ $('.hidden').hide(); When people click on the first question, I want the second question to appear (and the first question to turn to grey, using a 'done' class). $('.visible:not(.done)').click(function(){ $(this).addClass('done'); $('.hidden:first').toggle(500).removeClass('hidden').addClass('visible'); }) The first question is now done (class:done) and the 2nd question should be the only one to react to a click(), and so on... But it doesn't work: the other <tr> appear only when I click on the 1st <tr>. Can someone give me a hand on this problem ? Thank you.

  • jquery specific show buttons on hover

    - by bob
    I have an application creating a bunch of divs through a loop. Each div has the class "product" so it looks like <div class="product"> !.....stuff here ....! <div class="show_on_hover">...buttons here... </div> </div> so there are about 12 of these same divs per page. I would like to hover over a specific one and show the specific "show_on_hover" div which is initially set to display:none. $('.product').hover(function() { $(.show_on_hover).show(); }, function () { $(.show_on_hover).hide(); } ); That is what I have so far but it will show ALL of the .show_on_hovers on the page so I am wondering how to get only the specific one you have moused over to show. This effect is seen on youtube when you mouseover any of the comments, and some comment tools pop up. Thanks!
