  • Can't get ScrollTo to work with keyboard arrows

    - by adamwstl
    I'm trying to setup the Jquery plugin SerialScroll with Ariel's added keyboard controls. I'm calling these three JS files: serialScroll.js scrollTo.js keyboard.js (the keyboard control snippet) Html I'm trying to manipulate. Want it to jump from ind-photo to ind-photo on arrow left and right. <div id="photos"> <div class="ind-photo"><img src="2.jpg" /></div> <div class="ind-photo"><img src="3.jpg" /></div> </div> I can't get it to work at all. I know there are likely slight things that are going to be off, but this isn't working at all. Thanks in advance.

  • JS function returning another function

    - by Michael
    I want to understand about variables, that has been used in returning function. This is example code Prototype = {} Prototype.F = { bind: function() { var args = arguments, __method = args.shift(), object = args.shift(); return function() { return __method.apply(object, args.concat(arguments)); } } } function ObjectA() { ... this.addListener = Prototype.F.bind(this.eventSource.addListener, this.eventSource); ... } var a = ObjectA(); a.addListener(this); // assuming 'this' here will point to some window object As I understand the returning function in F() is not evaluated until it's called in the last line. It's ok to accept. So addListener will hold a function body containing 'apply'. But what I don't understand, when addListener is called, what kind of parameters it is going to have? particularly _method and args will always be uninitialized?

  • Faking Fixed Position in IE6

    - by Andrew
    I have a site that utilizes a bottom fixed position masthead here: http://www.entheospartners.com/newsite/ This setup works great in all browsers except IE6, which doesn't support fixed positioning in the least, so here's what I've done: When an IE6 user comes to the page, I make the determination if scrolling is necessary using this bit of code: var windowHeight = $(window).height(); var totalHeight = windowHeight - 100; // where 100 is the sum of the top nav height + footer height var contentHeight; if($('#subpage-content-small').length) { // main content div for a three column layout contentHeight = $('#subpage-content-small').height(); }; if($('#subpage-content-wide').length) { // main content div for a two column layout contentHeight = $('#subpage-content-wide').height(); }; if(contentHeight > totalHeight) { $('#container-container').css({ 'overflow-y' : "scroll", 'height' : totalHeight }); }; ...which calculates everything correctly, puts the scrollbars where they need to be (flush right), and sets them to the appropriate height. The problem is that the scrollbars don't move the content. I can't say that I've ever seen anything quite like this before, so I'm hoping someone else on here has. Thanks in advance! PS - Obviously, this needs to be looked at in IE6 for troubleshooting, which I know will be as painful for you as it is for me.

  • jQuery live() and stopPropagation() issue

    - by colourandcode
    I know that the live() event handles event bubbling different than all other jQuery events. jQuery recommends using 'return false', but in my case that doesn't work. The issue is: I have a DIV which contains an anchor tag. The DIV is bound using live(). Whenever I click the anchor tag inside this DIV it bubbles and calls the DIV's event. If I bind an event to that A tag which returns false it prevents the link from opening. Neither stopPropagation() or return false work in this case. Are there any other options? Ideally I'd like to keep the live() event around.

  • jQuery removing elements from DOM put still reporting as present

    - by RyanP13
    Hi, I have an address finder system whereby a user enters a postcode, if postcode is validated then an address list is returned and displayed, they then select an address line, the list dissappears and then the address line is split further into some form inputs. The issue i am facing is when they have been through the above process then cleared the postcode form field, hit the find address button and the address list re-appears. Event though the list and parent tr have been removed from the DOM it is still reporting it is present as length 1? My code is as follows: jQuery // when postcode validated display box var $addressList = $("div#selectAddress > ul").length; // if address list present show the address list if ($addressList != 0) { $("div#selectAddress").closest("tr").removeClass("hide"); } // address list hidden by default // if coming back to modify details then display address inputs var $customerAddress = $("form#detailsForm input[name*='customerAddress']"); var $addressInputs = $.cookies.get('cpqbAddressInputs'); if ($addressInputs) { if ($addressInputs == 'visible') { $($customerAddress).closest("tr").removeClass("hide"); } } else { $($customerAddress).closest("tr").addClass("hide"); } // Need to change form action URL to call post code web service $("input.findAddress").live('click', function(){ var $postCode = encodeURI($("input#customerPostcode").val()); if ($postCode != "") { var $formAction = "customerAction.do?searchAddress=searchAddress&custpc=" + $postCode; $("form#detailsForm").attr("action", $formAction); } else { alert($addressList);} }); // darker highlight when li is clicked // split address string into corresponding inputs $("div#selectAddress ul li").live('click', function(){ $(this).removeClass("addressHover"); //$("li.addressClick").removeClass("addressClick"); $(this).addClass("addressClick"); var $splitAddress = $(this).text().split(","); $($customerAddress).each(function(){ var $inputCount = $(this).index("form#detailsForm input[name*='customerAddress']"); $(this).val($splitAddress[$inputCount]); }); $($customerAddress).closest("tr").removeClass("hide"); $.cookies.set('cpqbAddressInputs', 'visible'); $(this).closest("tr").fadeOut(250, function() { $(this).remove(); }); });

  • Slider with keypress control bugs when keys pressed to quickly.

    - by Jaybuz
    Hello, I've made a slider that uses the left and right arrow keys to move the slide but when pressed to quickly it will bug a little and I was wondering if it's possible to limit the amount of presses in say a second. You can see it here: {link} $('#slider-nav div').click(function() { $('#slider-nav div').removeClass('selected').addClass(''); $('#slider-nav div:eq('+($.jcarousel.intval($(this).text())-1)+')').addClass('selected'); }) // Allow left and right keys to control slider $(document.documentElement).keypress(function(e) { var code = (e.keyCode ? e.keyCode : e.which); var direction = null; // handle cursor keys if (code == 37) { // left key direction = 'prev'; } else if (code == 39) { // right key direction = 'next'; } if (direction != null) { $('#slider-nav div.selected')[direction]().click(); } });

  • Do you know a date picker to quickly pick one day of the current week?

    - by Murmelschlurmel
    Most date pickers allow you to pick the date from a tine calendar or enter the date by hand. For example http://jqueryui.com/demos/datepicker/ This requires - two clicks (one to display the calendar and one to select the correct date) - good eyesight (usually the pop-up calendar is very small) - and good hand-eye coordination to pick the correct date in the tiny calendar with your mouse. That's no problem for power users, but a hassle for older people and computer beginners. I found a website with a different approach. It seems like their users mostly select dates of the current week. So they listed all the days of the week in a bar together with the weekday. The current day is marked in another color. There is a tiny calender icon on the right hand that opens up a regular date picker. That gives you access to all regular date picker functionality. Here is a screenshot: http://mite.yo.lk/assets/img/tour/de/zeiten-erfassen.png Do you know of any jquery plugin which has a similar feature? If not, do you any other plugin or widget which would help me speed up development ? Thank you!

  • How Do I Pass The Value (Not The Reference) of a JS Variable to a Function?

    - by ryan
    Here is a simplified version of something I'm trying to run: for (var i = 0; i < results.length; i++) { marker = results[i]; google.maps.event.addListener(marker, 'click', function() { change_selection(i); }); } but I'm finding that every listener uses the value of results.length (the value when the for loop terminates). How can I add listeners such that each uses the value of i at the time I add it, rather than the reference to i?

  • Need some help with onClick and an if/else issue...

    - by Adam
    I have a menu with seven items. If you click the first item, div one shows. If you click any other item (2 through 7) div two shows. That's what I'm looking to do. I'm new at all this but am pretty sure it's an if/else function, such that if I click on <a id="1">, show the first div, else show the second div. I suppose I can do a hide/show to get back to the first div. I'm going to keep poking around, but if I can't find it, any help is surely appreciated.

Now I see this solutions: Making flash (that I don't want to use) Create gif animation (and it will be big file size and quite bad quality)

  • Chrome: Dynamically created <style> tag does not have content?

    - by Shizhidi
    Hello. I encountered a weird problem when trying to write a cross-browser script. Basically my header looks like this <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> </head> Then in the body tag: <p id="hey">Hey</p> <input type="button" value="attachStyle" name="attachStyle" onclick="attachStyle();"></input> <script> function attachStyle() { var strVar=""; strVar += "<style type='text\/css'>#hey {border:5px solid red;}<\/script>"; $("head").append(strVar); } </script> The button works in Firefox, but not in Chrome. When I looked at the html DOM elements in the developer tool, the style tag was inserted but without content, like this: <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <style type='text/css'></script> </head> I'm curious as to what causes this? And how to create CSS style in a way that is cross-browser? Thanks!

  • How can I organize many results in a selectbox using php?

    - by zeckdude
    I have a select box that is part of a form. It is currently querying the addresses table and displaying the addresses into the select box. I plan on having up to 100 addresses. I'm looking for a solution where I can show all the states if the user clicks on the select box. Then if the user hovers over a state it will show all the addresses for that specific state. Then if the user clicks on an address, it will show that as the picked option in the select box. This is like a dropdown menu within a select box. Does anyone know where I can find a solution as this?

  • Using jsAnim.js

    - by mark
    I've been trying to set up a basic test animation using jsanim.js and using their example site to set up my html, css and js. However, I just can't figure it out (not a developer...designer!) and there isn't just a simple html, css, js file to download showing how to say animate a DIV left to right. The examples of how the library works are clear but I'm lacking something in the set up and looking at their source on the site is nuts...too much going on in there. Thanks to anyone with experience with jsAnim.js http://www.jsanim.com Best, Mark

  • Jquery: Is there some way to make val() return an empty string instead of 'undefined' for an empty list?

    - by Chris
    With Jquery, is there some way to make val() return an empty string instead of 'undefined' when called against an empty list of elements? E.g., I have this code: var x = $('#my-textbox-id').not('.watermark').val(); The idea is that I want to get the value of my textbox, but I want an empty string if it is currently showing the watermark (i don't want the watermark value!). The selector works, but i don't want 'undefined' - I want an empty string ''.
