  • JSTree select_node event and checkbox

    - by Ted Mosbey
    Hi there! I have a jstree in which I used the select_node event to toggle nodes(expand), and have therefore removed the toggle arrows in the tree since they look ugly and I've no need for them. Now I've added the checkbox plugin to use within the tree, but have found the select_node event is disabled when the plugin is active. How would I toggle my nodes with the checkbox plugin active, without re-adding the ugly toggle arrows? I could do it in the check/uncheck event, but I don't want to check/uncheck everytime I expand a node.

  • Patching this Code to apply dynamic (iPhone) background position

    - by Brian
    I posted a question previously that got off topic, I'm reposting with better code that I have VERIFIED is compatible with iPhone (it works with mine anyway!) I just want to apply background-position coordinates to the body element and call the script conditionally for iPhone, iPod, & iPad. Here's my conditional call for those devices: var deviceAgent = navigator.userAgent.toLowerCase(); var agentID = deviceAgent.match(/(iphone|ipod|ipad)/); if (agentID) { // do something } else { //do this } Now, I've found this excellent script that sets the "top: x" dynamically on the basis of scroll position. Everyone has told me (and ALL of the tutorials and Google search results as well) that it's impossible to set scroll position dynamically for iPhone because of the viewport issue. HOWEVER, they are wrong because if you scroll to the bottom of the page and view this javascript demo on iPhone, you can scroll and the <div style="background-position: fixed; top: x (variable)"></div> div DOES stay centered on iPhone. I really hope this question helps alot of people, I thought it was impossible, but it's NOT... I just need help stitching it together! The original code (you can test it on iPhone yourself) is here: http://stevenbenner.com/2010/04/calculate-page-size-and-view-port-position-in-javascript/ So I just need help getting the following code to apply the dynamic "background-position: 0 x" to the BODY tag where x is centered and relative to the viewport position. Also, needs to be nested inside the above code that is conditional for iPhone and similar devices. // Page Size and View Port Dimension Tools // http://stevenbenner.com/2010/04/calculate-page-size-and-view-port-position-in-javascript/ if (!sb_windowTools) { var sb_windowTools = new Object(); }; sb_windowTools = { scrollBarPadding: 17, // padding to assume for scroll bars // EXAMPLE METHODS // center an element in the viewport centerElementOnScreen: function(element) { var pageDimensions = this.updateDimensions(); element.style.top = ((this.pageDimensions.verticalOffset() + this.pageDimensions.windowHeight() / 2) - (this.scrollBarPadding + element.offsetHeight / 2)) + 'px'; element.style.left = ((this.pageDimensions.windowWidth() / 2) - (this.scrollBarPadding + element.offsetWidth / 2)) + 'px'; element.style.position = 'absolute'; }, // INFORMATION GETTERS // load the page size, view port position and vertical scroll offset updateDimensions: function() { this.updatePageSize(); this.updateWindowSize(); this.updateScrollOffset(); }, // load page size information updatePageSize: function() { // document dimensions var viewportWidth, viewportHeight; if (window.innerHeight && window.scrollMaxY) { viewportWidth = document.body.scrollWidth; viewportHeight = window.innerHeight + window.scrollMaxY; } else if (document.body.scrollHeight > document.body.offsetHeight) { // all but explorer mac viewportWidth = document.body.scrollWidth; viewportHeight = document.body.scrollHeight; } else { // explorer mac...would also work in explorer 6 strict, mozilla and safari viewportWidth = document.body.offsetWidth; viewportHeight = document.body.offsetHeight; }; this.pageSize = { viewportWidth: viewportWidth, viewportHeight: viewportHeight }; }, // load window size information updateWindowSize: function() { // view port dimensions var windowWidth, windowHeight; if (self.innerHeight) { // all except explorer windowWidth = self.innerWidth; windowHeight = self.innerHeight; } else if (document.documentElement && document.documentElement.clientHeight) { // explorer 6 strict mode windowWidth = document.documentElement.clientWidth; windowHeight = document.documentElement.clientHeight; } else if (document.body) { // other explorers windowWidth = document.body.clientWidth; windowHeight = document.body.clientHeight; }; this.windowSize = { windowWidth: windowWidth, windowHeight: windowHeight }; }, // load scroll offset information updateScrollOffset: function() { // viewport vertical scroll offset var horizontalOffset, verticalOffset; if (self.pageYOffset) { horizontalOffset = self.pageXOffset; verticalOffset = self.pageYOffset; } else if (document.documentElement && document.documentElement.scrollTop) { // Explorer 6 Strict horizontalOffset = document.documentElement.scrollLeft; verticalOffset = document.documentElement.scrollTop; } else if (document.body) { // all other Explorers horizontalOffset = document.body.scrollLeft; verticalOffset = document.body.scrollTop; }; this.scrollOffset = { horizontalOffset: horizontalOffset, verticalOffset: verticalOffset }; }, // INFORMATION CONTAINERS // raw data containers pageSize: {}, windowSize: {}, scrollOffset: {}, // combined dimensions object with bounding logic pageDimensions: { pageWidth: function() { return sb_windowTools.pageSize.viewportWidth > sb_windowTools.windowSize.windowWidth ? sb_windowTools.pageSize.viewportWidth : sb_windowTools.windowSize.windowWidth; }, pageHeight: function() { return sb_windowTools.pageSize.viewportHeight > sb_windowTools.windowSize.windowHeight ? sb_windowTools.pageSize.viewportHeight : sb_windowTools.windowSize.windowHeight; }, windowWidth: function() { return sb_windowTools.windowSize.windowWidth; }, windowHeight: function() { return sb_windowTools.windowSize.windowHeight; }, horizontalOffset: function() { return sb_windowTools.scrollOffset.horizontalOffset; }, verticalOffset: function() { return sb_windowTools.scrollOffset.verticalOffset; } } };

  • Load more function in Javascript

    - by erastusnjuki
    EDIT: This question was initially too general, I think. So What I really need is a very good tutorial on how to implement the Load More function on Safari for iPhone just like the Twitter website(mobile.twitter.com) does. Just a wordpress plugin won't really help. But if the plugin is well explained, like if it is wptouch, home(that also has this function) that can also do. I know that it doesn't really matter that it is being displayed on a mobile device, but the point I am stressing is that if such a function is well explained, then it will be up to me to know how to customize it to suit me. I am using a javascript function to load entries that come from the database dynamically, so that content opens in the same page (like with twitter(tweets feed) and facebook(news feed)). The php/html version(That opens a page in a new tab) is echo '<a href="http://'. $_SERVER['HTTP_HOST'] .'/'.$domain_page.'?form='.$form_id.'&page='.($page+1).'">Load more entries&rsaquo; </a>'; The javascript/ajax version: <div id="call_hv<?php echo md5($_SERVER['REQUEST_URI']); ?>" class="ajax-load-more"> <img id="spinner<?php echo md5($_SERVER['REQUEST_URI']); ?>" class="spin" src="<?php bloginfo('template_directory'); ?>/images/main-ajax-loader.gif" style="display:none" alt="" /> <a class="ajax" href="javascript:$ajax_hv('#spinner<?php echo md5($_SERVER['REQUEST_URI']); ?>').fadeIn(200); $ajax_hv('#ajaxentries_hv<?php echo md5($_SERVER['REQUEST_URI']); ?>').load('form='<? echo $form_id; ?>&page=<?php echo $page+1;?>', {}, function(){ $ajax_hv('#call_hv<?php echo md5($_SERVER['REQUEST_URI']); ?>').fadeOut();})">Load more entries... </a>

  • Dependent Dropdowns (Linked Selects) with single class (no other selectors)

    - by AJ
    I am trying to create multiple dependent dropdowns (selects) with a unique way. I want to restrict the use of selectors and want to achieve this by using a single class selectors on all SELECTs; by figuring out the SELECT that was changed by its index. Hence, the SELECT[i] that changed will change the SELECT[i+1] only (and not the previous ones like SELECT[i-1]). For html like this: <select class="someclass"> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="mercedes">Mercedes</option> <option value="audi">Audi</option> </select> <select class="someclass"> </select> <select class="someclass"> </select> where the SELECTs other than the first one will get something via AJAX. I see that the following Javascript gives me correct value of the correct SELECT and the value of i also corresponds to the correct SELECT. $(function() { $(".someclass").each(function(i) { $(this).change(function(x) { alert($(this).val() + i); }); }); }); Please note that I really want the minimum selector approach. I just cannot wrap my head around on how to approach this. Should I use Arrays? Like store all the SELECTS in an Array first and then select those? I believe that since the above code already passes the index i, there should be a way without Arrays also. Thanks a bunch. AJ

  • window.open() in an iPad on load of a frame does not work

    - by user278859
    I am trying to modify a site that uses "Morten's JavaScript Tree Menu" to display PDFs in a frames set using the Adobe Reader plug-in. On the iPad the frame is useless, so I want to open the PDF in a new tab. Not wanting to mess with the tree menu I thought I could use JavaScript in the web page being opened in the viewer frame to open a new tab with the PDF. I am using window.open() in $(document).ready(function() to open the pdf in the new tab. The problem is that window.open() does not want to work in the iPad. The body of the HTML normally looks like this... <body> <object data="MypdfFileName.pdf#toolbar=1&amp;navpanes=1&amp;scrollbar=0&amp;page=1&amp;view=FitH" type="application/pdf" width="100%" height="100%"> </object> </body> I changed it to only have a div like this... <body> <div class="myviewer" ></div> </body> Then used the following script... $(document).ready(function() { var isMobile = { Android : function() { return navigator.userAgent.match(/Android/i) ? true : false; }, BlackBerry : function() { return navigator.userAgent.match(/BlackBerry/i) ? true : false; }, iOS : function() { return navigator.userAgent.match(/iPhone|iPad|iPod/i) ? true : false; }, Windows : function() { return navigator.userAgent.match(/IEMobile/i) ? true : false; }, any : function() { return (isMobile.Android() || isMobile.BlackBerry() || isMobile.iOS() || isMobile.Windows()); } }; if(isMobile.any()) { var file = "MypdfFileName.pdf"; window.open(file); }else { var markup = "<object data='MypdfFileName.pdf#toolbar=1&amp;navpanes=1&amp;scrollbar=0&amp;page=1&amp;view=FitH' type='application/pdf' width='100%' height='100%'></object>"; $('.myviewer').append(markup); }; }); Everthing works except for window.open() on the iPad. If I switch things around widow.open() works fine on a computer. In another project I am using window.open() successfully on the iPad from an onclick function. I tried using a timer function. I also tried adding an onclick function to the div and posting a click event. In both cases they worked on a computer but not an iPad. I am stumped. I know it would make more sense to handle the ipad in the tree menu frame, but that code is so complex I can't figure out where to put/modify the onclick event. Is there a way to change the object so that it opens in a new tab? Is anyone familiar enough with Mortens Tree Menu code that can tell me how to channge the on click event so that it opens the pdf in a new tab instead of opening a page in the frame? Thanks

  • Problem with table resizing after automatically removing from jquery one column (this only happens i

    - by user297433
    Hi. I have a table with some columns. Something like this: tr1td1 one remove button tr1td2 one remove button ... The table has the size of the div#outer When I click remove button I remove with jquery the entire column . In Firefox everything's fine the table's columns resize to fill the div but in Internet Explorer the table's columns remain just as they are. It's like the browser doesn't refresh the css style. Because if I refresh the page the table looks just as it shoud be. Any ideas?

  • Unobstrusive pseudo-classes and attribute selectors emulation in IE

    - by Álvaro G. Vicario
    I'm trying to emulate some pseudo-classes and attribute selectors in Internet Explorer 6 and 7, such as :focus, :hover or [type=text]. So far, I've managed to add a class name to the affected elements: $("input, textarea, select") .hover(function(){ $(this).addClass("hover"); }, function(){ $(this).removeClass("hover"); }) .focus(function(){ $(this).addClass("focus"); }) .blur(function(){ $(this).removeClass("focus"); }); $("input[type=text]").each(function(){ $(this).addClass("text"); }); However, I'm still forced to duplicate selector in my style sheets: textarea:focus, textarea.focus{ } And, to make things worse, IE6 seems to ignore all the selectors when it finds an attribute: input[type=text], input.text{ /* IE6 ignores this */ } And, of course, IE6 ignores selectors with multiple classes: input.text.focus{ /* IE6 ignores this */ } So I'm likely to end up with this mess: input[type=text]{ /* Rules here */ } input.text{ /* Same rules again */ } input[type=text]:focus{ } input.text_and_focus{ } input.text_and_hover{ } input.text_and_focus_and_hover{ } My question: is there any way to read the rules or computed style defined for a CSS selector and apply it to certain elements, so I only need to maintain one set of standard CSS?

  • Events not registering after replaceWith

    - by strager
    When I replaceWith an element to bring one out of the DOM, then replaceWith it back in, events registered to it do not fire. I need to events to remain intact. Here's my Javascript: var replacement = $(document.createElement('span')); var original = $(this).replaceWith(replacement); replacement .css('background-color', 'green') .text('replacement for ' + $(this).text()) .click(function() { replacement.replaceWith(original); }); Live demo In the demo, when you click an element, it is replaced with another element using replaceWith. When you click the new element, that is replaced with the original element using replaceWith. However, the click handler does not work any more (where I would think it should).

  • "Intercepting" user input into text box and removing it

    - by James P
    I have a text box that I would like to do some validation on. At the moment I have this code: function updateChanger() { // Validate input var likeMessage = validateInput($("#like").val()); alert(likeMessage); } function validateInput(input) { input = input.replace(/[^a-zA-Z0-9:\(\/\)\s\.,!~]/g, ""); return input; } This successfully trims out unwanted characters in the likeMessage variable, but the character still gets entered into the text box. I would like to stop that from happening. I know it will have something to do with $("#like").val() but the only thing I can think of is just chopping off the end character from the text box value, would this suffice? Thanks for any help!

  • Javascript form validation events

    - by user307922
    Hi All, I am making a small form for a php app and had a question regarding javascript validation. What is the best event to run the javascript validation on the input value? Is it the "focusout" event? I used "focusout" to originally but it creates problems when the user hits enter while they are still focused on any particular field in the form. Should I run the js validation when the user clicks submit? Just looking for some advice. Thanks! Chuck

But the problem is, while i cross the li element with just a second, even the interval is calling, and showing the link. but i need to show only, if i stay inside 3sec and it need to hide there after, again i stay back 3sec. anything wrong with my code?, else any one give me the best suggestion? Thanks.
