  • Ordering z-indexes in an array

    - by Tom Gullen
    I have an array which looks something along the lines of resourceData[0][0] = "pic1.jpg"; resourceData[0][1] = 5; resourceData[1][0] = "pic2.jpg"; resourceData[1][1] = 2; resourceData[2][0] = "pic3.jpg"; resourceData[2][1] = 900; resourceData[3][0] = "pic4.jpg"; resourceData[3][1] = 1; The numeric represents the z-index of the image. Minimum z-index value is 1. Maximum (not really important) is 2000. I have all the rendering and setting z-indexes done fine. My question is, I want to have four functions: // Brings image to z front function bringToFront(resourceIndex) { // Set z-index to max + 1 resourceData[resourceIndex][1] = getBiggestZindex() + 1; // Change CSS property of image to bring to front $('#imgD' + resourceIndex).css("z-index", resourceData[resourceIndex][1]); } function bringUpOne(resourceIndex) { } function bringDownOne(resourceIndex) { } // Send to back z function sendToBack(resourceIndex) { } So given then index [3] (900 z): If we send it to the back, it will take the value 1, and [3] will have to go to 2, but that conflicts with [1] who has a 2 z-index so they need to go to three etc. Is there an easy programatical way of doing this because as soon as I start doing this it's going to get messy. It's important that the indexes of the array don't change. We can't sort the array unfortunately due to design. Update Thanks for answers, I'll post the functions here once they are written incase anyone comes across this in the future (note this code has zindex listed in [6]) // Send to back z function sendToBack(resourceIndex) { resourceData[resourceIndex][6] = 1; $('#imgD' + resourceIndex).css("z-index", 1); for (i = 0; i < resourceData.length; i++) { if (i != resourceIndex) { resourceData[i][6]++; $('#imgD' + i).css("z-index", resourceData[i][6]); } } }

  • 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.

  • one click, two 'click' event fired

    - by Toni Michel Caubet
    I just want to toggle some elements when a link is clicked: This is how i am trying (But i don't really think that it matters much for this question what's inside the event function callback): /* mostrar exceso de comentarios a peticion del usuario*/ $('.toggleComments').click(function(){ console.log('.toggleComments'); if($(this).parents('.helpContent').find('.commentHideble:visible').length > 0){ $(this).text('+ <?=get_texto_clave('show_old_comments')?>').removeClass('toggleCommentsActive').append(' ('+$(this).parents('.helpContent').find('.commentHideble:not:visible').length+'+)'); }else{ $(this).text('- <?=get_texto_clave('hide_old_comments')?>').addClass('toggleCommentsActive'); } $(this).parents('.helpContent').find('.commentHideble').slideToggle(100); }); I even tried a boolean but gave me same result /* mostrar exceso de comentarios a peticion del usuario*/ var ctoggle = false; $('.toggleComments').click(function(){ if(ctoggle == false){ ctoggle = true; console.log('.toggleComments'); if($(this).parents('.helpContent').find('.commentHideble:visible').length > 0){ $(this).text('+ <?=get_texto_clave('show_old_comments')?>').removeClass('toggleCommentsActive').append(' ('+$(this).parents('.helpContent').find('.commentHideble:not:visible').length+'+)'); }else{ $(this).text('- <?=get_texto_clave('hide_old_comments')?>').addClass('toggleCommentsActive'); } $(this).parents('.helpContent').find('.commentHideble').slideToggle(100); ctoggle = false; } }); Why the log is being fired twice by click?

  • Iterate over defined elements of a JS array

    - by sibidiba
    I'm using a JS array to Map IDs to actual elements, i.e. a key-value store. I would like to iterate over all elements. I tried several methods, but all have its caveats: for (var item in map) {...} Does iterates over all properties of the array, therefore it will include also functions and extensions to Array.prototype. For example someone dropping in the Prototype library in the future will brake existing code. var length = map.lenth; for (var i = 0; i < length; i++) { var item = map[i]; ... } does work but just like $.each(map, function(index, item) {...}); They iterate over the whole range of indexes 0..max(id) which has horrible drawbacks: var x = []; x[1]=1; x[10]=10; $.each(x, function(i,v) {console.log(i+": "+v);}); 0: undefined 1: 1 2: undefined 3: undefined 4: undefined 5: undefined 6: undefined 7: undefined 8: undefined 9: undefined 10: 10 Of course my IDs wont resemble a continuous sequence either. Moreover there can be huge gaps between them so skipping undefined in the latter case is unacceptable for performance reasons. How is it possible to safely iterate over only the defined elements of an array (in a way that works in all browsers and IE)?

  • Refactor: Javascript block

    - by Shpigford
    Need some help refactoring this code: $("span[rel=color_content]").ColorPicker({ onChange: function (hsb, hex, rg) { $("span[rel=color_content]").css('background-color', '#' + hex); } }); $("span[rel=color_link]").ColorPicker({ onChange: function (hsb, hex, rg) { $("span[rel=color_link]").css('background-color', '#' + hex); } }); $("span[rel=color_selected]").ColorPicker({ onChange: function (hsb, hex, rg) { $("span[rel=color_selected]").css('background-color', '#' + hex); } }); $("span[rel=color_page]").ColorPicker({ onChange: function (hsb, hex, rg) { $("span[rel=color_page]").css('background-color', '#' + hex); } }); $("span[rel=color_player]").ColorPicker({ onChange: function (hsb, hex, rg) { $("span[rel=color_player]").css('background-color', '#' + hex); } }); The only thing changing between each is the contents of the rel attribute.

    Hi, I am using facebox popup in one of my pages. I am having a button in the popup dialog. When I click that button the facebox popup should close (the same way it closes when we press outside the popup). How to do that? Also, I am doing some Ajax stuff when that button is being pressed so I cannot override the onClick event.

  • 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.

  • 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/

  • how to disable on click event

    - by user1819709
    function insertQuestion(form) { var x = "<img src='Images/plussigndisabled.jpg' width='30' height='30' alt='Look Up Previous Question' class='plusimage' name='plusbuttonrow'/><span id='plussignmsg'>(Click Plus Sign to look <br/> up Previous Questions)</span>" ; if (qnum == <?php echo (int)$_SESSION['textQuestion']; ?>) { $('#mainPlusbutton').replaceWith(x); } //append rows into a table code, not needed for this question } .... $('.plusimage').live('click', function() { plusbutton($(this)); }); function plusbutton(plus_id) { // Set global info plusbutton_clicked = plus_id; // Display an external page using an iframe var src = "previousquestions.php"; $.modal('<iframe src="' + src + '" style="border:0;width:100%;height:100%;">'); return false; } <form id="QandA" action="<?php echo htmlentities($action); ?>" method="post"> <table id="question"> <tr> <td colspan="2"> <a onclick="return plusbutton();"> <img src="Images/plussign.jpg" width="30" height="30" alt="Look Up Previous Question" class="plusimage" id="mainPlusbutton" name="plusbuttonrow"/> </a> <span id="plussignmsg">(Click Plus Sign to look up Previous Questions)</span> </td> </tr> </table> <table id="questionBtn" align="center"> <tr> <th> <input id="addQuestionBtn" name="addQuestion" type="button" value="Add Question" onClick="insertQuestion(this.form)" /> </th> </tr> </table> </form> In the code above I am able to replace an image with another image when the if statement is met. But my problem is that when the image is replaced, it does not disable the on click event. My question is that when the image is replaced, how do I disable the onclick event onclick="return plusbutton();? Could unbind click work in this situation. I don't want to use href=# because I don't want to include # at the end of the url

  • 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); }; }); });

  • 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
