  • AJAX Closures and targeting 'this'

    - by Nick Lowman
    In the code example below the success callback function logs 'input#04.update' four times rather than each individual input, which makes sense seeing how closures work but how would I go about targeting each individual input using this. <input type="text" name="" id="01" class="update"> <input type="text" name="" id="02" class="update"> <input type="text" name="" id="03" class="update"> <input type="text" name="" id="04" class="update"> function updateFields(){ $('input.update').each(function(){ $this = $(this); $.ajax({ data: 'id=' + this.id, success: function(resp){ console.log($this); $this.val(resp) } }); }); }

    - by sharataka
    When the user clicks on a button in the form associated with it's image, I'd like the image to disappear on success. I'm having trouble implementing this. Any advice? <script type="text/javascript"> $(document).ready(function() { $(".removebutton").submit(function(event){ event.preventDefault(); $.ajax({ type:"POST", url:"/munch_video/", data: { 'video_id': $('.video_id', this).val(), // from form 'playlist': $('.playlist').val(), // from form 'add_remove': $('.add_remove').val(), // from form }, success: function(message){ alert(message); $('.span8').removeClass('.video_id', this); } }); return false; }); }); </script> <div class = "span8" style = "width: 900px;"> <!-- wrapper div --> <div class='wrapper huluDotCom'> <!-- image --> <div class="image" style="position: relative; left: 0; top: 0;"> <a href = "/partners/Business/huluDotCom"> <img src = "/huluDotCom.png"> </a> <!-- munchbutton div --> <div class='munchbutton'> <form method='post' action = '/munch_video/ ' class = 'removebutton'><div style='display:none'><input type='hidden' name='csrfmiddlewaretoken' value='dKrS8NzqPWFLM6u8wJrAeid4nGw1avGK' /></div> <input type="hidden" value="Channel" class = "playlist"/> <input type="hidden" value="huluDotCom" class = "video_id"/> <input type="hidden" value="remove_video" class = "add_remove"/> <input type='submit' class="btn btn-danger" value='Remove from plate'/> </form> </div> <!-- end munchbutton div --> </div> <!-- end image div --> </div> <!-- end wrapper div --> <!-- wrapper div --> <div class='wrapper TheEllenShow'> <!-- image --> <div class="image" style="position: relative; left: 0; top: 0;"> <a href = "/partners/Business/TheEllenShow"> <img src = "/TheEllenShow.png"> </a> <!-- munchbutton div --> <div class='munchbutton'> <form method='post' action = '/munch_video/ ' class = 'removebutton'><div style='display:none'><input type='hidden' name='csrfmiddlewaretoken' value='dKrS8NzqPWFLM6u8wJrAeid4nGw1avGK' /></div> <input type="hidden" value="Channel" class = "playlist"/> <input type="hidden" value="TheEllenShow" class = "video_id"/> <input type="hidden" value="remove_video" class = "add_remove"/> <input type='submit' class="btn btn-danger" value='Remove from plate'/> </form> </div> <!-- end munchbutton div --> </div> <!-- end image div --> </div> <!-- end wrapper div --> </div>

  • How to clear a textbox based on a checkbox using Javascript

    - by LoftyWofty
    I am trying to code in javascript (to avoid validation triggers at the server) to clear a text box if the checkbox associated with it is unchecked. I have this code ... <input type="checkbox" id="chkOTHER" onclick="document.getElementById('txtOtherFlag').value='';" /> <asp:TextBox ID="txtOtherFlag" runat="server" AutoPostBack="True" CausesValidation="True" ValidationGroup="ValidationGroup1"></asp:TextBox> The problem is the Javascript inside the checkbox is not triggering to remove the value in the text box. Even if this worked, it's incorrect as it would blank out the text box every time the checkbox is triggered whether it is checked or not. I need to resolve this in the client side only. Thank you

  • How to determine which enemy is hit and destroy it alone

    - by Jon Ferriter
    http://jsfiddle.net/5DB6K/ I have this game being made where you shoot enemies from the sides of the screen. I've got the bullets moving and being removed when they reach the end of the screen (if they didn't hit any enemy) and removing the enemy when they collide with it. //------------collision----------------// if(shot === true){ bulletY = $('.bullet').position().top + 2; bulletX = $('.bullet').position().left + 2; $('.enemy').each(function(){ if($('.enemy').hasClass('smallEnemy')){ enemyY = $(this).position().top + 7; enemyX = $(this).position().left + 7; if(Math.abs(bulletY - enemyY) <= 9 && Math.abs(bulletX - enemyX) <=9){ $(this).remove(); score = score + 40; bulletDestroy(); } } }); } However, the bullet destroys every enemy if the collision check is right which isn't what I want. I want to check if the enemy has the class of either smallEnemy, medEnemy, or lrgEnemy and then do the collision check which is what I thought I had but it doesn't seem to work. Also, the game starts to lag the more and more time goes on. Would anyone know the reason for that?

  • Do i need a hashtag in Javascript to pass as a Div

    - by Mike
    How do i insert this php DivSomething into Javascript? Since Javascript needs a hashtag to recognize that as a div. Is there a way to tell JS that this is a Div or there's other better way to do it? Any help would be very much appreciated. <script> /*How do i insert a var DivSomething into JS with a hashtag */ /* DivSomething is php dynamic. It returns a Div. It can be #Div1, #Div2, #Div3... */ var DivSomething = '<?php echo $Highlight; ?>' $(function() { $('#MouseHere').hover(function() { $('#' + DivSomething).css('background-color', '#ffffff'); }, function() { // on mouseout, reset the background colour $('#' + DivSomething).css('background-color', ''); </script>

  • Making an element draggable?

    - by user246114
    Hi, I'm trying to make an element draggable, like so: var element = $("<li id='test'>Hello</li>"); element.appendTo("#panelParent"); element.draggable("enable"); element.draggable("option", "connectToSortable", '#panelTarget'); element.draggable("option", "helper", 'clone'); element.draggable("option", "revert", 'invalid'); nothing happens when I try dragging this element. It works fine though if I embed the object in the page beforehand instead of trying to dynamically create the element. Any idea what I'm missing? For example, this works: $(function() { $("#test").draggable({ connectToSortable: '#panelTarget', helper: 'clone', revert: 'invalid' }); }); <ul> <li id='test'>Hello</li> </ul> Thanks

  • How to submit the correct div elements (not the div that's hidden)?

    - by user356651
    Hello, I have the following code working fine but the problem is that it always submits the first div (article) even though it's hidden. My question is how do I submit the form and the elements in the form in the div that's shown? (if I select Music radiobutton, I want to submit the input elements of the Music Div not the Article div. Thanks. $(document).ready(function(){ $("input[name$='itemlist']").click(function() { var selection = $(this).val(); $("div.box").hide(); $("#"+selection).show(); }); }); <!--radio buttons--> <div id="articleselection"><input name="itemlist" type="radio" value="article" /> Article/Book </div> <div id="musicselection"><input name="itemlist" type="radio" value="music" /> Music</div> <!--article div starts--> <div id="article" class="box"> <table class="fieldgroup"> <tr><td>Journal Title: <input id="JournalTitle" name="JournalTitle" type="text" size="60" class="f-name" tabindex="1" value="JournalTitle"> </table> <table class="fieldgroup"> <tr><td>Article Author: <input id="ArticleAuthor" name="ArticleAuthor" type="text" size="40" class="f-name" tabindex="2" value="<"ArticleAuthor"></td></tr> </table> </div> <!--music div starts--> <div id="music" class="box"> <table class="fieldgroup"> <tr><td>Music Title: <input id="Music Title" name="Music Title" type="text" size="60" class="f-name" tabindex="1" value="Music Title"> </table> <table class="fieldgroup"> <tr><td> Music Author: <input id="MusicAuthor" name="Music Author" type="text" size="40" class="f-name" tabindex="2" value="<"MusicAuthor"></td></tr> </table> </div>

  • Disable form submission via Enter key on only _some fields

    - by justSteve
    I want to retain the conventional 'form submits when i press Enter' behavior because users are familiar with. But by reflex, they often hit enter when they finish with a text input box - but before they are actually done with the complete form. I'd like to hijack the Enter key only when then focus is on a certain class of input. Looking Related Questions this looks like what I'm looking for: if (document.addEventListener) { document.getElementById('strip').addEventListener('keypress',HandleKeyPress,false); } else { document.getElementById('strip').onkeypress = HandleKeyPress; } but the if (document.addEventListener) { is unfamiliar.

  • Same function on multiple div classes doesn't work

    - by Sebass van Boxel
    I'm doing something terribly wrong and just can't find the solution for it. Situation: I've got a number of products with a number of quotes per product. Those quote automatically scroll in a div. If the scroll reaches the last quote is scroll back to the first one. What works: The function basically works when it's applied on 1 div, but when applied on multiple div it doesn't scroll back to the first one or keeps scrolling endlessly. This is the function i've written for this: function quoteSlide(divname){ $total = ($(divname+" > div").size()) $width = $total * 160; $(divname).css('width', ($width)); console.log ($totalleft *-1); if ($width - 160 > $totalleft *-1){ $currentleft = $(divname).css('left'); $step = -160; $totalleft = parseInt($currentleft)+$step; }else{ $totalleft = 0; } $(divname).animate(     { left: $totalleft }, // what we are animating     'slow', // how fast we are animating     'swing', // the type of easing     function() { // the callback }); } It's being executed by something like: quoteSlide('#quotecontainer_1'); in combination with a setInterval so it keeps scrolling automatically. This is the jsFiddle where it goes wrong (So applied on more than 1 div) http://jsfiddle.net/FsrbZ/. This is the jsFiddle where everything goes okay. (applied on 1 div) When changing the following: quoteSlide('#quotecontainer_1'); quoteSlide('#quotecontainer_2'); setInterval(function() { quoteSlide('#quotecontainer_1'); quoteSlide('#quotecontainer_2'); }, 3400);? to quoteSlide('#quotecontainer_1'); setInterval(function() { quoteSlide('#quotecontainer_1'); }, 3400);? it does work... but only on 1 quotecontainer.

  • Search box inside a div. Django

    - by Juliette Dupuis
    In my django app I display a list of elements (friends name) thanks to a loop: <div> {% for friend in group %} <p>{{ friend.name }} <p> {% endfor %} </div> I would like to create a search box on the top of my list in order to be able to find only the friends the user wants. I would like the search bar does not need to click to send the request (an example is the Airtime searchbox on top of the facebook friends list). I have absolutely no idea on how to do that, and I'm looking for hints or tips to start. Thank you very much for your help.

  • Function to get the font and calculate the width of the string not working on first instance

    - by user3627265
    I'm trying to calculate the width of the string based on the font style and size. The user will provide the string, the font style and the font size, and then after giving all the data the user will hit the submit button and the function will trigger. Basically this script works but only when the submit button is hit twice or the font is selected twice,. I mean if you selec DNBlock as a font, it will not work for first time, but the second time you hit submit, it will then work. I'm not sure where is the problem here, but when I used the default font style like Arial, times new roman etc it works perfectly fine. Any Idea on this? I suspected that the font style is not being rendered by the script or something. Correct me if I'm wrong. Thanks //Repeat String String.prototype.repeat = function( num ) { return new Array( num + 1 ).join( this ); } //Calculate the width of string String.prototype.textWidth = function() { var fntStyle = document.getElementById("fntStyle").value; if(fntStyle == "1") { var fs = "DNBlock"; } else if(fntStyle == "2") { var fs = "DNBlockDotted"; } else if(fntStyle == "3") { var fs = "DNCursiveClassic"; } else if(fntStyle == "4") { var fs = "DNCursiveDotted"; } else if(fntStyle == "5") { var fs = "FoundationCursiveDots-Regul"; } var f = document.getElementById("fntSize").value.concat('px ', fs), o = $('<div>' + this + '</div>') .css({'position': 'absolute', 'float': 'left', 'white-space': 'nowrap', 'visibility': 'hidden', 'font': f}) .appendTo($('body')), w = o.width(); o.remove(); return w; } //Trigger the event $("#handwriting_gen").submit(function () { var rptNO = parseInt($('#rptNO').val()); $("[name='txtLine[]']").each(function(){ alert(this.value.repeat(rptNO).textWidth()); if(this.value.repeat(rptNO).textWidth() > 1000) { $(this).focus(); $(this).css({"background-color":"#f6d9d4"}).siblings('span.errorMsg').text('Text is too long.'); event.preventDefault(); } }); });
