  • jQuery make child div visible on hover (on effective li element only, not parent!)

    - by Dennis
    I've already tried all of the existing posts related to this, but they doesn't work as I want it... The HTML: <ol class="sortable"> <li> <div> <a href="#">Start Page</a> <div class="li_options"> <a href="#"><img src="img/icons/small_add.png" /></a> <a href="#" onClick="[..]"><img src="img/icons/small_remove.png" /></a> </div> <div class="clear"></div> </div> <ol> <li> <div> <a href="#">Sub Seite</a> <div class="li_options"> <a href="#"><img src="img/icons/small_add.png" /></a> <a href="#" onClick="[..]"><img src="img/icons/small_remove.png" /></a> </div> <div class="clear"></div> </div> <ol> <li> <div> <a href="#">Sub Sub Seite</a> <div class="li_options"> <a href="#"><img src="img/icons/small_add.png" /></a> <a href="#" onClick="[..]"><img src="img/icons/small_remove.png" /></a> </div> <div class="clear"></div> </div> </li> </ol> </li> </ol> </li> <div class="clear"></div> This should look like this: Start Page Sub Page Sub Page I want the div.li_options which is set for every li element to be shown only on hovering element. I know, that the parent's li is also being "hovered" on hovering child elements, but I don't those "li_options" to be displayed. The best solution so far: $(document).ready(function() { $('.sortable li').mouseover(function() { $(this).children().children('.li_options').show(); }).mouseout(function() { $(this).children().children('.li_options').hide(); }); }); But with this, parents aren't being excluded... I don't know how to point on them, because there can be endless levels. Do you know how to get this working?

  • jQuery: How do I pass a value into an Ajax call?

    - by Legend
    I am updating some div as follows: for(var i = 0; i < data.length; i++) { var query = base_url + data[i]; $.ajax({ url: query, type: 'GET', dataType: 'jsonp', timeout: 2000, error: function() { self.html("Network Error"); }, success: function(json) { $("#li" + i).html("<img src='" + json.result.list[0].url + "' />") } }); } The value of i does not work inside the ajax call. I am trying to pass the value of i so that it can attach the element to the proper div. Can someone help me out?

  • Speed up a web service for auto complete and avoid too many method calls.

    - by jphenow
    So I've got my jquery autocomplete 'working,' but its a little fidgety since I call the webservice method each time a keydown() fires so I get lots of methods hanging and sometimes to get the "auto" to work I have to type it out and backspace a bit because i'm assuming it got its return value a little slow. I've limited the query results to 8 to mininmize time. Is there anything i can do to make this a little snappier? This thing seems near useless if I don't get it a little more responsive. javascript $("#clientAutoNames").keydown(function () { $.ajax({ type: "POST", url: "WebService.asmx/LoadData", data: "{'input':" + JSON.stringify($("#clientAutoNames").val()) + "}", contentType: "application/json; charset=utf-8", dataType: "json", success: function (data) { if (data.d != null) { var serviceScript = data.d; } $("#autoNames").html(serviceScript); $('#clientAutoNames').autocomplete({ minLength: 2, source: autoNames, delay: 100, focus: function (event, ui) { $('#project').val(ui.item.label); return false; }, select: function (event, ui) { $('#clientAutoNames').val(ui.item.label); $('#projectid').val(ui.item.value); $('#project-description').html(ui.item.desc); pkey = $('#project-id').val; return false; } }) .data("autocomplete")._renderItem = function (ul, item) { return $("<li></li>") .data("item.autocomplete", item) .append("<a>" + item.label + "<br>" + item.desc + "</a>") .appendTo(ul); } } }); }); WebService.asmx <WebMethod()> _ Public Function LoadData(ByVal input As String) As String Dim result As String = "<script>var autoNames = [" Dim sqlOut As Data.SqlClient.SqlDataReader Dim connstring As String = *Datasource* Dim strSql As String = "SELECT TOP 2 * FROM v_Clients WHERE (SearchName Like '" + input + "%') ORDER BY SearchName" Dim cnn As Data.SqlClient.SqlConnection = New Data.SqlClient.SqlConnection(connstring) Dim cmd As Data.SqlClient.SqlCommand = New Data.SqlClient.SqlCommand(strSql, cnn) cnn.Open() sqlOut = cmd.ExecuteReader() Dim c As Integer = 0 While sqlOut.Read() result = result + "{" result = result + "value: '" + sqlOut("ContactID").ToString() + "'," result = result + "label: '" + sqlOut("SearchName").ToString() + "'," 'result = result + "desc: '" + title + " from " + company + "'," result = result + "}," End While result = result + "];</script>" sqlOut.Close() cnn.Close() Return result End Function I'm sure I'm just going about this slightly wrong or not doing a better balance of calls or something. Greatly appreciated!

  • jquery element not defined, but it used to skip it...

    - by pfunc
    I recently transferred a site to a new host. Reloaded everything, and the javascript that worked fine before is breaking at an element it can't find. $('#emailForm') is not defined. Now, the #emailform isn't on the page, but it wasn't before either, and JS used to skip this and it would just work. Not sure why this is happening. Any clues?

  • jQuery: Adding li element only if it not already there?

    - by Legend
    I am constructing an <li> element like this: var element = $("<li></li>") .html(mHTML) .attr('id', "elemid"); I am trying to add this element to a <ul> element only if it doesn't already exist. Any ideas on how to do this? Am I supposed to use contains() to see if the ul element contain the html and then decide? For instance, <ul id="elemul"> <li id="elemli1">Element 1</li> <li id="elemli2">Element 2</li> <li id="elemli3">Element 3</li> </ul> If I try adding Element 1, it should not add it. What should I do if its a longer string (not really long but about 150 characters). Do I go about using hashmaps?

  • How do I change the curosr during a jQuery synchronous browser blocking POST?

    - by Tommy
    $.ajax({ url: "/cgi-bin/stats.exe", method: "post", async: false, data: { refresh: "a41" } }); Using ajax post synchronously - "async: false". While it blocks the browser during the active request, what is the most efficient way to change the cursor to the hourglass or display a wait .gif? Perhaps set the cursor as it enters this function then change it back in the success or complete function? Any advice is appreciated. Thank You.

  • What's the best way to call jQuery scripts, in HTML/PHP template, or seperate js file?

    - by j-man86
    StackOverflow is telling me this is a subjective question, but I think it's a matter of fact! I have a number of scripts that I'm using on different parts of my site. In terms of making fewer http requests, I know it's better to combine all of these scripts into one .js file. However, isn't a waste of time for a page to call a .js full of 10 or 15 different functions when it's only using one? The other method I am using is to use PHP conditional statements... <?php if( is_page() ) { > $(document).ready(function(){ ... }); <?php } ?> What's the best method or comination of these methods?

I have short listed Flex, JSF[apache trinidad], html5, gwt these technologies. None of them provide timeline charts on their own. I am looking at other options such as using third party libraries.

  • jquery XML .html() instead of .text() is not displaying?

    - by Xtian
    I can't seem to figure out this problem. I am trying to get xml to render html tags. The problem I am having using .text() will display but not recognize any html tags. If I use .html() or just call var long2 = $(this).find('long'); nothing will show up in Safari or IE. I have xml paragraph I have text in here that needs bold tags or tags which is why i need html tags in the xml to be recognized. Code: $(document).ready(function(){ $.ajax({ type: "GET", url: "xml/sites.xml", dataType: "xml", success: function(xml) { $(xml).find('site').each(function(){ var id = $(this).attr('id'); var title = $(this).find('title').text(); var Class = $(this).find('class').text(); $('<div class="'+Class+'" id="link_'+id+'"></div>').html('<p class="title">'+title+'</p>').appendTo('#page-wrap'); $(this).find('desc').each(function(){ var url = $(this).find('url').text(); var long = $(this).find('long').text(); $('<div class="long"></div>').html(long).appendTo('#link_'+id); $('#link_'+id).append('<a href="http://'+url+'">'+url+'</a>'); var long2 = $(this).find('long'); $('<div class="long2"></div>').html(long2).appendTo('#link_'+id); }); }); } });

  • jQuery Ajax loads URL multiple times, how do I unbind/rebind properly?

    - by gmoz22
    I load a SELECT element via Ajax (list of brands), get its selected value (brand id) and load another SELECT via another Ajax URL (list of templates for currently selected brand). Here's my code: $(document).ready( function() { // DO NOT cache Ajax calls $.ajaxSetup ({ cache: false }); // loader var ajax_load = "Loading..."; // Brands List URL var loadBrandUrl = "getBrandsList.php"; // Templates List URL var loadTemplateUrl = "getTemplatesList.php"; $("#brandslistSelect").html(ajax_load).load(loadBrandUrl) .ajaxComplete(function(){ // Brands select loaded /* Load Templates SELECT the first time since no .change() has happened */ var selectedBrand = $("#brandslistSelect option:selected").attr("value"); // get the value console.log(selectedBrand); // Log selected brand to console // get Templates select, commented for now since it does an infinite loop // $("#templateslistSelect").html(ajax_load).load(loadTemplateUrl, { BrandId: selectedBrand } ); /* End initial load template */ /* On interaction with the Brands SELECT */ $("#brandslistSelect").change(function () { // on interaction with select selectedBrand = $("#brandslistSelect option:selected").attr("value"); // get the value // get Templates SELECT $("#templateslistSelect").html(ajax_load).load(loadTemplateUrl, { BrandId: selectedBrand } ) }); /* End interaction with the Brands SELECT */ }); }); It returns selectedBrand in the console 3 times : selectedBrand = undefined selectedBrand = undefined selectedBrand = 101 Now, if I uncomment the following line, same output as above but it also loads the templates URL indefinitely : // $("#templateslistSelect").html(ajax_load).load(loadTemplateUrl, { BrandId: selectedBrand } ); Any idea how I could modify this code to make it work as intended? Thanks for your help stackOverflow community!

  • How do I bind the Overlay Tool for new Ajax elements in Jquery?

    - by Hooman Ahmadi
    Hi, I'm using: echo $javascript->link('tools.overlay-1.0.4', false); which is initialized with: $(".overlay_popup").overlay({ expose: '#000000', close: '.close_overlay', finish: { top: 'center', left: 'center', absolute: false } }); I call the overlay popup box like this: echo $html->link( "add part", array('controller'=>'garage_parts', 'action'=>'addfrompartlist', $gcar['GarageCar']['id'], $gcar['GarageCar']['car_id']), array('class'=>'js-ajax overlay_popup', 'id'=>'add_part_overlay', 'rel'=>'.overlay_container') ); This all works fine and dandy, however I have an ajax function that dynamically adds the "add part" hyperlink button shown above and I have no idea how to bind this new button to the overlay. Normally, I would use something like this: $(".overlay_popup").bind("click", function(){... but this didn't work for the overlay. Any ideas on how I can successfully do this?

    - by DavidR
    I have a function. I pass to it an object with a list of questions and answers. I generate a random number from a range equal to the number of questions in the object. The script check to see if that question has been asked, and if not, it asks it, the correct answer is then passed to a variable correct. I want to give 4 possible answers, each one randomly selected from the list of possible answers. I have this. I just want to know what is the best way to ensure that the correct answer is placed in the list. So far, this is what I have: it puts four answers into four targeted boxes.
