  • How come $(this) is undefined after ajax call

    - by JohnnyQ
    I am doing an ajax request when an anchor tag is clicked with an ID set to href. Btw, this anchor tag is dynamically created. <a href="983" class="commentDeleteLink">delete</a> When the anchor tag is clicked the following code is executed: $('.commentDeleteLink').live('click', function(event) { event.preventDefault(); var result = confirm('Proceed?'); if ( result ) { $.ajax({ url: window.config.AJAX_REQUEST, type: "POST", data: { action : 'DELCOMMENT', comment : $('#commentText').val(), comment_id : $(this).attr('href') }, success: function(result) { alert($(this).attr('href')); //$(this).fadeOut(slow); } }); } }); When I tried to display $(this).attr('href') it says it's "undefined". What I really want to do is fadeOut the anchor tag but when I investigated the value of $(this) it is "undefined". What could be wrong with the snippet above?

  • Check if previous clicked value is inside an array

    - by Lelly
    I have a list with different categories. All the list item are clickable. I want the user to pick between 1 and 3 items. They can toggle their choice, but maximum is alway 3. So far, so good. Where it get tricky for me, is that I have some special categories that can't be combined with any others. When a user click on one of these, all the other categories deselect and they can't add any other, (these item have only 1 category selection possible) Exemple: Let's say "Car" is a special category. If they click on Car, everything else deselect, Car is selected, and they can't select anything else. BUT they can click again on Car to deselect it, and from there the logic start over. What's missing in my code is the part in bold just above this. My code: $j('.chooseCat li').on('click',function(){ var $this = $j(this); //list item clicked var catId = $this.children("a").attr("rel"); // list item id var specialCat = ['6','36','63']; if ($this.hasClass("selected")) { $this.removeClass("selected"); $j("#categorySuggestions p.error").hide("fast") } else { if( $j.inArray(catId, specialCat) !== -1 ) { $j('.chooseCat li').removeClass("selected"); $this.addClass("selected"); } else { if ($j('.chooseCat li.selected').length <= 2){ $this.addClass("selected"); } else { $j("#categorySuggestions p.error").show("fast").html("You cannot select any more categories"); } } } }); A working jsFiddle of where Iam at: http://jsfiddle.net/nfQum/9/

  • slidepanel/hover help

    - by Josh
    I'm trying to create a menu navigation system from the top of the page. I want it so when I hover over the link, it drops down (the link drops down; so it'd be as if there was a whole field being hidden beyond the 0px mark) with the related field. I've gotten it to work, somehow but it still isn't right. A few issues are: when I hover over .drop_slide and then if I choose to close it by hovering back over the .drop_slide it does as it's told, which is "slide, slide". I'm interested in rectifying this issue so it doesn't do that, however I just don't know how. The idea is to have multiple links in the .slide, so I need it to be constantly open while the user mouses over the other links. Should this be created in one field? If so, how would I do that with a drop down in mind? Am I approaching this completely wrong? Lol. Should I be researching into .animate? I've been looking at it actually, but I can't get anything to grow negatively. Say; marginTop: -85px or something. ANY help is appreciated, thanks! $(document).ready(function(){ function slide() { $("#panel").slideToggle("slow"); } $(".drop_slide").hover(slide, stop); $("#panel").hover(stop, slide); });

  • Dynamically choosing css property in animation

    - by paddywhack
    Hi, It seems a straightforward thing but I'm not having much success. I'm just implementing a simple animation moving a div left or up using animate() but I would like to be able to set the "top" and "left" css properties dynamically. I would like to use the same function rather than have to have two, one for "left" and one for "top". Here's some code which gives the idea. function test($element){ $element.click(function(){ var cssProperty; var direction = "left"; var moveTo = "100px"; if (direction === "top") { cssProperty = "top"; } else { cssProperty = "left"; } /*Using variable as CSS property - This doesn't work */ $(this).animate({ cssProperty: moveTo }, 1000); /*Using variable as the CSS Values - This does */ $(this).animate({ left: moveTo }, 1000); }); } Variables works on the css value side but not on the css selector side. Anyone have any suggestions? Thanks

  • Is it possible to exclude some elements from parsing when using regular expression and .replace()?

    - by Fletus Mefitis
    <script language="javascript"> $("div.post-content , .parsedsig").each(function(){ if($(this).html().indexOf("[/tabulaScriptum]") != -1) { pattern = /\[tabulaScriptum=(.*?)\]([^\[]*)\[\/tabulaScriptum\]/gi $(this).html($(this).html().replace(pattern, "<div class='tabulaScriptum'><div class='tabulaNomen'>$1</div><div class='tabulaImpleo'>$2</div></div>")) } }); </script> This script is working perfectly, except for one thing... I need not to replace [tabulaScriptum=][/tabulaScriptum] in certain elements. For example, I don't want to replace those "tags" in element that has class .code-box. Is it possible? Clarification: element .code-box is located within .post-content. Clarification #2: this script creates simple division spoiler. .tabulaScriptum is spoier's body, .tabulaNomen is spoiler's name and button which, in turn, reveals(or hides) .tabulaImpleo on click. Reveal\hide script is located in some other place, and I didn't post it here since it doesn't really matter. Clarification #3: http://jsfiddle.net/PRtsw/1/ fiddle.

    This question already has an answer here: remove objects from array by object property 3 answers I have two JavaScript objects: object_1 = [ {'value': '9:00', 'text':'9:00 am', 'eventtime':'09:00:00' }, {'value': '9:30', 'text':'9:30 am', 'eventtime':'09:30:00' }, {'value': '10:00', 'text':'10:00 am', 'eventtime':'10:00:00' }, {'value': '10:30', 'text':'10:30 am', 'eventtime':'10:30:00' }, {'value': '11:00', 'text':'11:00 am', 'eventtime':'11:00:00' }, {'value': '11:30', 'text':'11:30 am', 'eventtime':'11:30:00' }, ]; object_2 = [ {'eventtime': '10:30:00'}, {'eventtime': '11:00:00'} ]; I want to remove the object in object_1 which has the same eventtime value and store it in a new array/object .

  • Opposite of .find()

    - by Ben
    Is there an opposite of .find()? Where $('.myclass').except('#myid'); Would grab all elements with .myclass except the element with #myid. I know I could do $('.myclass[id=myid]') in this example, but seems like it would be helpful in other cases. Thanks

  • sequencing function calls in javascript - are callbacks the only way?

    - by tim
    I read through various threads like this one for example. But it really escapes me how to accomplish the following: I have 4 functions, and want them happen one after another in sequence. Notice they are in incorrect order, to get my point across. I want the result that will output "1, 2, 3, 4' function firstFunction(){ // some very time consuming asynchronous code... console.log('1'); } function thirdFunction(){ // definitely dont wanna do this until secondFunction is finished console.log('3'); } function secondFunction(){ // waits for firstFunction to be completed console.log('2'); } function fourthFunction(){ // last function, not executed until the other 3 are done. console.log('4'); } I tried to figure out callbacks but am getting lost :( Isn't there some simple way to do this? Like looping through an array...

  • Run function in current element by get short code inside

    - by happi
    In stead of adding an ID (IdAddMore) to run script inside ID(widget1) like that : <div class="widget" id="widget1"> <div class="content"> <div id="IdAddMore"></div> <script type='text/javascript'> $("#IdAddMore").selectme({ Numpost:3, Postyle : "Enter your style", }); </script> </div> </div> (widget is added automatically when I add more new widget, It means I can have widget3, widget10, ....Index(3,10..) is any and is not sorted.) Widget is a HTML/JS widget. I want run selectme by short code instead of repeating script in each widget. <div class="widget" id="widget1"> <div class="content"> [3][mystyle] </div> </div> <div class="widget" id="widget50"> <div class="content"> [4][yourstyle] </div> </div> ........... How can I write only script to catch short code in current element is added : I write script below but it does not work. Check for me, thanks your help. <script type='text/javascript'> var getdata = document.getElementsByClassName(".content").innerText || document.getElementById(".content").textContent; var thevalue = []; getdata.replace(/\[(.*?)\]/g, function(g0,g1){thevalue.push(g1);}); $(".widget").selectme({ Numpost:thevalue[0], Postyle: ""+thevalue[1]+"", }); </script>

  • Why isn't this button firing the anchor tag?

    - by Noor
    My idea is to press a button that takes me to a web page. I've created a thing that dynamically creates a button and an anchor tag. When the button is clicked, I want it to "click"/fire up the anchor tag.. I've uploaded a demo to my site, when you try it out just leave everything as it is. Click the first button then the add button right away.. then try to click the dynamically created button. Nothing happens, but if you watch the source you can find an anchor tag with the ID FL1000, I've set it up so that the anchor tag gets the ID from the value of the created button + 1000 just incase I need to use that ID.. Thanks guys... edit: this is optimized for google chrome, haven't tried it out with other browser.

  • How to return function in document ready?

    - by FatDogMark
    I don't know if it is possible to do this, like I have 2 js files. The first Js File: var news_pos, about_pos, services_pos, clients_pos; function define_pos(){ var $top_slides=$('#top_slides'), $mid_nav=$('#mid_nav'), $news_section=$('#section-1'); var fixed_height = $top_slides.height()+$mid_nav.height(); news_pos = fixed_height-20 ; about_pos = fixed_height+$news_section.height(); services_pos = fixed_height+$news_section.height()*2; clients_pos = fixed_height+$news_section.height()*3; } $(document).ready(function(){ var section_news = $('#section-1'), section_about = $('#section-2'), section_services = $('#section-3'), section_clients = $('#section-4'); setheight(); function setheight(){ var section_height=$(window).height()+200; $section_news.height(section_height); $section_about.height(section_height); $section_services.height(section_height); $section_clients.height(section_height); define_pos(); } }); The second JS File: $(document).ready(function(){ var nav = { '$btn1':$('#btn1'), '$btn2':$('#btn2'), '$btn3':$('#btn3'), '$btn4':$('#btn4'), '$btn5':$('#btn5'), myclick : function(){ myclicked(nav.$btn1,0); myclicked(nav.$btn2,news_pos); myclicked(nav.$btn3,about_pos); myclicked(nav.$btn4,services_pos); myclicked(nav.$btn5,clients_pos); function myclicked(j,k){ j.click(function(e) { e.preventDefault(); $('html,body').animate({scrollTop: k}, 1000); }); } //Is it right to do return{'myclick':myclick}, how to call? seems not logical } } nav.myclick(); // Here will not work because it say news_pos is undefined //if I use setTimeout(nav.myclick,1000), it will works but I want to run it right the when position is caculated. }); How do I pass the nav.myclick() function to the frist js file and put it in setheight() and under define_pos()? By the way writing codes right in stackoverflow is strange,press tab not really give you any spacing.

  • start javascript code with $(function, etc

    - by YAmikep
    I am studying Backbone and the todo example apps from http://todomvc.com/ I have noticed there are 3 severals ways of starting the code in the files: $(function() { // code here }); $(function( $ ) { // code here }); (function() { // code here }()); I do not understand the differences and when I should use one over the other. I also saw some people using this to start their code: $(document).ready(function(){ // code here }); From what I have seen, this is the full way of writing it right? In a more general way, should I always include my javascript code into something like that in each files? Thanks for your advice.
