  • div:hover is affecting all elements below

    - by Jesse
    Here is a sample fiddle: http://jsfiddle.net/K2zyU/4/ The problem I am experiencing is that the main navigation hover is applying to the sub navigation items. If for example, I were to move the list above the main navigation div the hover works as I would expect? I'm unsure of what I'm missing / doing wrong in this case. <div class="main">MAIN NAV<div> <ul class="sub"> <li>SUB NAV 1</li> <li>SUB NAV 2</li> <li>SUB NAV 3</li> <li>SUB NAV 4</li> <li>SUB NAV 5</li> <li>SUB NAV 6</li> </ul> .main:hover, .sub li:hover { color: black; background-color: #f3ffff; opacity: .6; }

  • How to make this JavaScript much faster?

    - by Ralph
    Still trying to answer this question, and I think I finally found a solution, but it runs too slow. var $div = $('<div>') .css({ 'border': '1px solid red', 'position': 'absolute', 'z-index': '65535' }) .appendTo('body'); $('body *').live('mousemove', function(e) { var topElement = null; $('body *').each(function() { if(this == $div[0]) return true; var $elem = $(this); var pos = $elem.offset(); var width = $elem.width(); var height = $elem.height(); if(e.pageX > pos.left && e.pageY > pos.top && e.pageX < (pos.left + width) && e.pageY < (pos.top + height)) { var zIndex = document.defaultView.getComputedStyle(this, null).getPropertyValue('z-index'); if(zIndex == 'auto') zIndex = $elem.parents().length; if(topElement == null || zIndex > topElement.zIndex) { topElement = { 'node': $elem, 'zIndex': zIndex }; } } }); if(topElement != null ) { var $elem = topElement.node; $div.offset($elem.offset()).width($elem.width()).height($elem.height()); } }); It basically loops through all the elements on the page and finds the top-most element beneath the cursor. Is there maybe some way I could use a quad-tree or something and segment the page so the loop runs faster?

    - by Bragaadeesh
    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.

  • Why do spaces appear in my string?

    - by Abs
    Hello all, I have this function below which returns all IDs of checked boxes on my page seperated by a comma. It works great but the problem is, it seems to put a lot of white space after each checkbox ID. I can't seem to figure out why? /*Returns selected checkbox ID in string seperated by comma */ function get_selected_chkbox(){ var checked_string = ''; $('#report_table').find("input[type='checkbox']").each(function(){ if(this.checked){ checked_string = checked_string + this.id + ','; } }); alert(checked_string);//test1 ,test2 , return checked_string; } Thanks all for any help

  • No results are returned when using Flickr JSON request

    - by Martijn1981
    I'm still fairly new to AJAX and I'm experimenting with Twitter and Flickr. Twitter is working fine so far, but I've run into some issues with the Flickr API. I'm getting no results back. The URL seems to be working fine and I'm pointing to the right object containing the array ('items'). Can anybody tell me what I'm doing wrong please? Thanks! $('#show_pictures').click(function(e){ e.preventDefault(); $.ajax({ url: 'http://api.flickr.com/services/feeds/photos_public.gne?format=json&jsoncallback=?&tags=home', dataType: 'jsonp', success: function(data) { $.each(data.items, function(i, item){ $('<div></div>') .hide() .append('<h1>'+item.title+'</h1>') .append('<img src="'+item.media.m+'" >') .append('<p>'+item.description+'</p>') .appendTo('#results') .fadeIn(); }) }, error: function(data) { alert('Something went wrong!'); } }); });

  • 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?

  • 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?

  • Insert something .after a set of elements if the first in the set has a certain class.

    - by Adripants
    I would like to add a label AFTER a group of radio inputs IF the first has a certain class <label>Has the strategy and all of it's relevant background documents been uploaded</label> <label for="Radio1"><input type="radio" name="uploaded" class="required cat1" id="Radio1">Yes</label> <label for="Radio2"><input type="radio" name="uploaded" id="Radio2">No</label> Radio1 has the class, but I'd like to insert a label after the last (in this case Radio2) I thought I could use this: $('input[type="radio"].cat1').siblings('input:last').after('<label>Hi!</label>'); But it doesn't work. Can you pick what I am doing wrong?

  • Script that replaces strings doesn't work on some sites

    - by groovy354
    I've created a simple Chrome extension that seeks for certain strings using regex and replaces matches with predefined text. It works well on most websites, but somehow the script doesn't take effect on, for example, Lifehacker (like this page http://lifehacker.com/5939740/five-best-audio-editing-applications?popular=true ). The code is: $('p, h1, h2, h3, span, .content, .post-body').each(function(){ //do something with $(this) }); Any ideas why is Lifehacker's site resistant to my script?

  • jqGrid: Is it possible to commit a cell change when tabbing off instead of pressing Enter?

    - by The Matt
    I have a simple in-line edit in my grid, and I want to commit the change when the user tabs off the textbox. The default behavior of jqGrid forces the user to press 'Enter' to commit the change, but this is non-intuitive for our users. onSelectRow: function(id) { $(gridCoreGroups).editRow(id, true, undefined, function(response) { alert("hello world"); } } I've worked my way through the events provided, but they all happen as a result of the user pressing 'Enter', which I want to avoid. Is there something I can wire up that would trigger an action when the user tabs off this cell?

  • Javascript function returning number with two decimals...?

    - by muzzledBYbrass
    I have a function to return points along a line and my return comes back with two decimal points...? For example, a return of my variable px will be something like -88.4029.032940598. vx is the x vector and mult is the distance of the line plus distance to calculate the point. Here is the operation that is returning these values: var mult = parseFloat(mag + theUnit); var px = coord_one.x_point + (vx * mult); console.log(px); Never have seen this before- I appreciate any and all help!
