  • How do I clear the text contents of a div in javascript?

    - by Ben
    I'm temporarily adding contents to a div,tempDiv, and adding that to a link which is appended to a div, #contentHere, that's displayed. I need to clear the contents of tempDiv so that the links aren't appended to each other, creating a string of urls that don't link to anywhere. $(document).ready(function(){ $.getJSON("data.php", function(data){ for(i = 0; i < 5; i++){ $("#tempDiv").append(data.justIn[i].dataLink+ ' '); $("#contentHere").append("<a href=\"#tempDiv\">Click to go to the div link</a>"); //I need to clear the contents of tempDiv here } }); }); Solutions to clearing the temporary contents of the div as I go?

    $(document).ready(function () { $('#keywordframe').contents().find("#step12").html(''); $('#keywordframe').contents().find("#step12").html('11'); $('#keywordframe').contents().find("#step13").html(''); $('#keywordframe').contents().find("#step13").html('12'); $('#keywordframe').contents().find("#step14").html(''); $('#keywordframe').contents().find("#step14").html('13'); $('#keywordframe').contents().find("#step15").html(''); $('#keywordframe').contents().find("#step15").html('14'); }); I try to use the above code to change the content in an iframe, but it is not working. Unless I put alert(''); on top of $('#keywordframe').contents().find("#step12").html(''); if just will take effect. What is the reason for that, anyone could help?

  • How to get number of elements of a class before a certain element

    - by David Shaikh
    I want to know how many elements of a certain class appear in the DOM before an element that let's say has been clicked on. <html> <div class="a"> </div> <div class="b"> <div class="a"> </div> </div> <button>CLick me!</button> <div class="a"> </div> </html> So in the previous DOM tree if the element to be clicked is the button, and Im looking for divs with class "a" it should return 2, even though in the whole tree there are 3, but "before" the button there are only 2. How could I do that? Thanks

  • Calling a Function Based on a String Which Contains the Function Name

    - by Phonethics
    var foo1,foo2; switch (fn) { case "fade" : foo1 = "fadeOut"; foo2 = "fadeIn"; break; case "slide" : foo1 = "slideUp"; foo2 = "slideDown"; break; } eval("$('.cls1')." + foo1 + "();"); currentSlideIndex = currentSlideIndex + n; eval("$('.cls1')." + foo2 + "();"); Any better way to achieve this without using eval ? Im not a very big fan of using eval unless absolutely necessary.

  • Letting user carry on after three attempts

    - by sMilbz
    In my spelling game there is a grid that is populated with words. The words are hidden and the aim of the game is to spell the word that is highlighted with the aid of a sound and a picture. To highlight a word you press the "next" button. At the moment if you spell the word correctly it says "well done" and you can advance to the next word, but if you spell it incorrectly you have to keep attempting the word until it is complete. As the game is designed for children I do not think this is the best approach, so I would like to make it so you can advance after 3 incorrect attempts. I have played around with the script so much trying to put counters on incorrect attempts and then making the button active but cannot seem to get it to work. Can someone please help me? Here is the script for the button var noExist = $('td[data-word=' + listOfWords[rndWord].name + ']').hasClass('wordglow2'); if (noExist) { $('.minibutton').click(); } else { $('.minibutton').click('disable'); $("#mysoundclip").attr('src', listOfWords[rndWord].audio); audio.play(); $("#mypic").attr('src', listOfWords[rndWord].pic); pic.show(); } }); "wordglow2" is the style applied if the word is spelt correctly. Here is a fiddle to help understand... http://jsfiddle.net/smilburn/ZAfVZ/4/

  • RadGrid Ajax PopAlert

    - by user272671
    I have a situation where I need to, based on user selection and some server-side processing, display a message to allow user to choose to continue processing or cancel. I have a RadGrid populated with data from the database. When User adds a new item to the grid,I want to do some processing in the back end and then inform the user of what could result and give him/her the choice to continue and believe that a message box or modal popup/radalert is the best way to do it, but how do I create the message in the back end and then using a popup, display the message and block until user responds. How do I do it please?

  • IE 8 and text fading

    - by DMIL
    I have a problem with fading text in IE 8, 7 and 6 (obviously). The text has a black outline during the animation that completely ruins the effect. Is there a workaround? I've read a bunch of answers about this problem and none made sense. Please take a look at this simple jsFiddle http://jsfiddle.net/LhSK7/ in IE 8, and show me how to fix it if possible. Edit: screenshot of the problem: http://i43.tinypic.com/1z6h1th.png I thought it might be because of the VirtualBox, but all other browsers display it correctly in VirtualBox. Edit #2: the problem can sort of be solved by setting the background color of the element being faded, which while still pretty ugly in IE 8 and below, at least gets rid of the black outline.

  • Simple Sinatra Ajax Not Working

    - by proteantech
    I was trying make an AJAX call from a static file on my computer to a simple sinatra service. The ajax call was returning with an error and no details. The server logged no errors either. Another strange symptom was that the Origin in the request header was null. I turns out that you can't make cross domain ajax calls without a little extra effort. You can set the Access-Control-Allow-Origin header on your sinatra response to expose your service to external domains using a snippet like this: get '/hi' do response['Access-Control-Allow-Origin'] = '*' content_type 'text/plain' "Hello World" end There's also another header you can set to allow other HTTP Methods besides gets, Access-Control-Request-Method. You can find more information by searching around for CORS: Cross Origin Resource Sharing and the previously mentioned headers. Oh, and in case you want to do this in Rails as well you can do something like this in your controller: after_filter :set_access_control_headers def set_access_control_headers headers['Access-Control-Allow-Origin'] = '*' headers['Access-Control-Request-Method'] = '*' end

  • Tabs.url is undefined

    - by Notionwork
    I have no clue what I'm doing wrong here! This should be working I believe. I'm writing a chrome extension and this should get the current tab's url and set the html of #current-tab to the url (for testing purposes). The code successfully gets to the callback, but it says that tab.url is undefined when I put it in an alert box, and it does not put it's value in #current-tab. Here's the code I have: $('#get-tab').click(function(){ chrome.tabs.query({"active" : true}, function(tab){ for (var i = 0; i < tab.length; i++) { alert(tab.url); $('#current-tab').append(tab.url); }; }); });

  • I need a simple slideshow for images of different sizes

    - by Darryl Young
    I'm looking for a very basic slideshow which displays images of various sizes. For example, the first image could be a standard 800x600 but the next might be a taller portrait image and so on. The slideshow doesn't need to have any controls. The specification just states that the page will be black and in the centre there'll be the area where images will display. As far as I know, it will be very simple like this - www.jeffcutter.net. I'm limited on time here so I'm not able to look into writing a custom one or anything like that. I just need to get some images displaying like in the example. Thanks in advance, it's much appreciated. Have a great weekend! Regards.

  • How does Facebook codes their Cropping tool?

    - by Trip
    I ask this because I am currently trying to work out my own technique, and there are huge strategic hangups for the entire site when your begin this. Of them are: Using jCrop and rMagick, it takes up a huge amount of processing ( to which I have backgrounded ). Because I have it backgrounded, I must by ajax develop a feature that auto-updates every five seconds to check when the backgrounding is done. Has anyone accomplished this with their sites? If so, what are some creative techniques you came across to keep the processing streamline, and the users happy?

  • class selector refuses after append to body

    - by supersize
    I'm appending loads of divs in a wrapper: var cubes = [], allCubes = '', for(var i = 0; i < 380; i++) { var randomleft = Math.floor(Math.random()*Math.floor(Math.random()*1000)), randomtop = Math.floor(Math.random()*Math.floor(Math.random()*1000)); allCubes += '<div id="cube'+i+'" class="cube" style="position: absolute; border: 2px #000 solid; left: '+randomleft+'px; top: '+randomtop+'px; width: 9px; height: 9px; z-index: -1"></div>'; } $('#wrapper').append(allCubes); // performance for(var i = 0; i < 380; i++) { cubes.push($('#cube'+i)); } and then I would like to make them all draggable with jQueryUI and log their current position. var allc = $('.cube'); allc.draggable().on('mouseup', function(i) { allc.each(function() { var nleft = $(this).offset().left; var ntop = $(this).offset().top; console.log('cubes['+i+'].animate({ left:'+nleft+',top:'+ntop+'})'); }); }); Unfortunenately it does not work. They are neither draggable nor there comes up a log. Thanks

  • Best approach to update a control after an Ajax request?

    - by Cuga
    I have a webpage that fires off an Ajax request which stores some data to a database and I want to update the webpage so that the user can see their changes have been submitted. There are at least 3 ways I can think of accomplishing this: Immediately update the webpage with plain JavaScript by grabbing the contents of the user's inputted text and immediately inserting it where it belongs. Have the ajax call return the stored text as the response, grab the response, and then insert this text where it belongs on the page using JavaScript Have the ajax call return a flag (say, true for successful db write, false otherwise), and if the flag is true, use JavaScript to grab the user's contents from the input control and insert it where it belongs elsewhere on the page Or another method not mentioned...? I don't mean this to be subjective, I just don't know which would be the best method to apply. My instinct tells me to go with the third item (return a flag, then update the field). Is this the best way? Thanks

  • Javascript int variable from ASP.NET MVC Model data?

    - by Anders Svensson
    I need to get model data into a javascript variable and use it as an int to compare values. But I can only figure out how to get the model data as strings, otherwise the compiler complains. So how can I get the max and taskBudgetHours as int variables in the Javascript? <script type="text/javascript"> $(document).ready(function () { $("#taskForm").submit(function (e) { var taskBudgetHours = $('#BudgetHours').val(); var max = '<%: Model.Project.RemainingBudgetHours %>'; var test = 'test'; alert(taskBudgetHours); alert(max); if (taskBudgetHours <= max) { //This doesn't work, seems to treat it as strings... return true; } else { //Prevent the submit event and remain on the screen e.preventDefault(); alert('There are only ' + max + ' hours left of the project hours.'); return false; } }); return; }); </script>
