  • AJAX: Problems returning multiple variables

    - by fwaokda
    First off sorry if I'm missing something simple just started working with AJAX today. I have an issue where I'm trying to get information from my database, but different records have different amounts of values. For instance, each record has a "features" column. In the features column I store a string. (ex: Feature1~Feature2~Feature3~Feature4... ) When I'm building the object I take apart the string and store all the features into an array. Some objects can have 1 feature others can have up to whatever. So... how do I return this values back to my ajax function from my php page? Below is my ajax function that I was trying and I'll provide a link with my php file. [ next.php : http://pastebin.com/SY74jV7X ] $("a#next").click(function() { $.ajax({ type : 'POST', url : 'next.php', dataType : 'json', data : { nextID : $("a#next").attr("rel") }, success : function ( data ) { var lastID = $("a#next").attr("rel"); var originID = $("a#next").attr("rev"); if(lastID == 1) { lastID = originID; } else { lastID--; } $("img#spotlight").attr("src",data.spotlightimage); $("div#showcase h1").text(data.title); $("div#showcase h2").text(data.subtitle); $("div#showcase p").text(data.description); $("a#next").attr("rel", lastID); for(var i=0; i < data.size; i++) { $("ul#features").append("<li>").text(data.feature+i).append("</li>"); } /* for(var j=1; j < data.picsize; j++) { $("div.thumbnails ul").append("<li>").text(data.image+j).append("</li>"); } */ }, error : function ( XMLHttpRequest, textStatus, errorThrown) { $("div#showcase h1").text("An error has occured: " + errorThrown); } }); });

  • Creating a pie chart for an app

    - by jhodgson4
    I'm developing an app which requires a pie chart to display a set number of modules. The modules need to be clickable, sending a value to the database for how many times the module has been clicked. The slices will change color etc depending on this database value. The slices will always be equal in size. All simple stuff. My question is what charting system would you use. I've been looking at google charts but I have no way of registering a value in a slice without changing its 'weight' in the chart. So ideally I would like to add data-stage="2" to each slice that I can access with a custom method. Also google charts seems quite heavy for what I need? Any advice would be greatly appreciated. Joe

  • Bootstrap-Switch options don't take effect

    - by Linda Keating
    I'm using Bootstrap-Switch and the documentation says that options can be passed as an object on initialization. enter link description here And here is a list of options: enter link description here So my code looks like this: var options = { onText: "Yes", onColor: 'primary', offColor: 'danger', offText: "No", animate: true, }; $("[name='radioGroup1']").bootstrapSwitch(options); And it all switch works fine, but none of the defaults are overwritten by the options. Anybody got any examples of how this might work? Thanks

  • color letters in a div

    - by Growler
    I've created a palindrome checker. I want to take it one step further and show the letters being compared as it is being checked. HTML: <p id="typing"></p> <input type="text" id="textBox" onkeyup="pal(this.value);" value="" /> <div id="response"></div> <hr> <div id="palindromeRun"></div> JS: To do this, I run the recursive check... Then if it is a palindrome, I run colorLetters(), which I'm trying to highlight in green each letter as it is being checked. Right now it is just rewriting palindromeRun's HTML with the first letter. I know this is because of the way I'm resetting its HTML. I don't know how to just grab the first and last letter, change only those letters' css, then increment i and j on the next setTimeout loop. var timeout2 = null; function pal (input) { var str = input.replace(/\s/g, ''); var str2 = str.replace(/\W/, ''); if (checkPal(str2, 0, str2.length-1)) { $("#textBox").css({"color" : "green"}); $("#response").html(input + " is a palindrome"); $("#palindromeRun").html(input); colorLetters(str2, 0, str2.length-1); } else { $("#textBox").css({"color" : "red"}); $("#response").html(input + " is not a palindrome"); } if (input.length <= 0) { $("#response").html(""); $("#textBox").css({"color" : "black"}); } } function checkPal (input, i, j) { if (input.length <= 1) { return false; } if (i === j || ((j-i) == 1 && input.charAt(i) === input.charAt(j))) { return true; } else { if (input.charAt(i).toLowerCase() === input.charAt(j).toLowerCase()) { return checkPal(input, ++i, --j); } else { return false; } } } function colorLetters(myinput, i, j) { if (timeout2 == null) { timeout2 = setTimeout(function () { console.log("called"); var firstLetter = $("#palindromeRun").html(myinput.charAt(i)) var secondLetter = $("#palindromeRun").html(myinput.charAt(j)) $(firstLetter).css({"color" : "red"}); $(secondLetter).css({"color" : "green"}); i++; j++; timeout2=null; }, 1000); } } Secondary: If possible, I'd just like to have it colors the letters as the user is typing... I realize this will require a setTimeout on each keyup, but also am not sure how to write this.

  • Javascript toggle using custom attributes

    - by Jacob
    Can't seem to get this to work for me, can anyone offer me some help? http://codepen.io/anon/pen/kABjC This should open and close a section of text based on click, it takes the ID # which is just a digit (1,2,3,4,etc) and using that id targets an id to open and close the section.

  • Want to set 'src' of script to my IP.

    - by Ozaki
    I have a script that links to the server I am hosting (IP can change) usually I would just use for links: var url ='http://' + window.location.hostname + 'end of url'; But in this case it isnt appearing to be so easy. I have tried: (1) $('#scriptid').attr('src', url); as well as: (2) var script = document.createElement( 'script' ); script.type = 'text/javascript'; script.src = url; $("#insert").append( script ); Now case (2) works loads the script runs the script. But when at the end of my script it hits the 'write data' it decides to replace the entire page with just the data. Any idea on how I can do this?

  • How do I avoid killing the native controls on a html5-video when i've started it programmaticly?

    - by Nils
    OK, so the deal is I've started making a little videoplayer, that works by clicking a div with an image, expanding the div and the image, and then exchanges the image with a html5-videotag. the code is as below. (It's very early on, so i know theres a lot that need improving, as in not using javascript to set styles and so on, but nevertheless, any insigts and tips are welcome, besides the answer to the main question) /*Begin Expander*/ var $videoplayer = $('<video width="640" height="360" preload="none" controls="" tabindex="0" style="position: relative;"><source type="video/mp4" src="/restalive/movies/big_buck_bunny.mp4"></source><source type="video/ogg" src="/restalive/movies/big_buck_bunny.ogv"></source></video>').appendTo('body'); $videoplayer.hide(); $(".ExpandVideo").each(function(i){ var $trigger = $(this); var $image = $trigger.find("img"); $image.css({ "width" : "100%" ,"height" : "auto" }) $trigger.css({ "display" : "block" ,"overflow" : "hidden" ,"width" : "200px" ,"float" : "left" }); $trigger.bind("click", function(e){ $trigger.animate({"width" : "640px"}, "fast", function(){ $image.replaceWith($videoplayer); $videoplayer.show(); $videoplayer.attr("id", "video" + i); var video = document.getElementById("video" + i); video.play(); }) }) }); However, the main problem is that when i've fired of the video like this (video.play()), the native controls stop working, i can no longer pause the video, even though the controls are there, and clickable, the video just starts playing immidiatley again when i trie to pause it. Which is a shame, because i want to use the native controls for simplicity.

  • Basic javascript function

    I have this function working <script type="text/javascript"> $(window).scroll(function() { if ($(window).scrollTop() == $(document).height() - $(window).height()) { $('div#loadmoreajaxloader').show(); $.ajax({ url: "loadmore.php?wall=<?php echo $wall; ?>&lastid=" + $(".postitem:last").attr("id"), success: function(html) { if (html) { $("#postswrapper").append(html); $('div#loadmoreajaxloader').hide(); } else { $('div#loadmoreajaxloader').html('<center><font color="white">No more posts to show.</font></center>'); } } }); } }); </script> But I need to have the same stuff happening (on IOS Devices), but instead of it happening when the browser reaches the loadmoreajaxeloader div, I simply need it to happen on an onclick event on a link. Thanks heaps. Tried to add code but didn't format so here it is http://pastebin.com/p2VUqZff

  • Display loading while webservice is running

    - by poseid
    On the initial request to a page, I trigger a webservice and want to display a loading message. When the page has finished loading, I want to remove the waiting message from screen, but display it again when a change event in a checkbox triggers an Ajax call with another loading message. This code is not behaving to the given spec: $(document).ready( $(function() { $('#loadingDiv').hide(); $('#productsDropDown') .change(function() { var prodValue = $(this).val(); $('#proddate').load('getpdate.php', {prod: prodValue }); }); $('#loadingDiv') .ajaxStart(function() { $(this).show(); }) .ajaxStop(function() { $(this).hide(); }) ; }); ); what am I doing wrong?

  • Good JavaScript engine for animating via Sprite Sheets (not in canvas)

    - by N. Taylor Mullen
    I've looked around a bit for a great JavaScript Sprite Sheet animator lib/engine but couldn't find any good ones so I thought I'd ask around =). What I'm looking for in the engine is: Animate an image in a non-canvas setting (ex: div via css or img tags) Control frame rate/animation speed Flags to loop or to animate once etc. Are there any engines like this out there? If not I can always make my own but then again, I don't want to re-invent the wheel =].

  • Not responding to events?

    - by Legend
    I currently have three Divs and only one of them is in focus at a given time. All of them line up in a film strip fashion. When I click a DIV not in focus, the current one moves to the left or right (depending on the direction) and the new one comes into focus. The divs can have content that has links. So my problem is that upon clicking on the divs not in focus, if I happen to click on a link, the event is captured. Is there anyway I can disable event detection for divs not in focus? What I am looking for is something like: if(div not in focus) disable all links if (div comes into focus) enable all links

  • Show content with fancybox like a Javascript Alert

    - by Ron Lens
    I try to show the content from a PHP-file in a fancybox but I can't handle it. Now it's the following situation: If a file permission problem occures a <div id="error"> is shown on the website. I'd like to have the content from <div id="error"> in fancybox. Everything I try I get the notice "The requested content cannot be loaded. Please try again later." That means the fancybox, it the file permission error occures, should be shown when the page is loading and not like usual shown when some events like click or mouseover. For example, if the error exists, the following content should be shown in the fancybox: <div style="width:100px; height:100px; background:#f00;"> <p>Failure</p> </div> This snippet is located in a file security_check.php. Now there are two possibilities. The 1st is to load the security_check.php directly into the fancybox or to put in the mentioned above snippet. So: how to load file contents into the fancybox?

  • Remember (persist) the filter, sort order and current page of jqGrid

    - by Jimbo
    My application users asked if it were possible for pages that contain a jqGrid to remember the filter, sort order and current page of the grid (because when they click a grid item to carry out a task and then go back to it they'd like it to be "as they left it") Cookies seem to be the way forward, but how to get the page to load these and set them in the grid before it makes its first data request is a little beyond me at this stage. Does anyone have any experience with this kind of thing with jqGrid? Thanks!

What can be wrong? P.S. - I need this return false statement, because I want to manipulate return data myself.
