position

问题 I am simply trying to position #elementA relative to #elementB. Half the time it ends up with one top value, half the time it gets another, and I can't figure out why. #elementA begins with this CSS: #elementA { display: block; opacity: 0; position: absolute; clear: both; margin-left: -49px; } Then, on $(document).ready(), I set the top value and fade it in. var p = $('#elementB').offset(); $('#elementA').css({ top: p.top - 2 }); $('#elementA').animate({opacity: 1}, 400); Why am I getting

问题 How to get xy coordinates of child element from parent element, and not the(body)?

问题 Good day all, I am using Google's new Face API (Link here) which works with improved FaceDetection. One of the things you get back is a List of Landmark objects, each of which has an X and Y coordinate to use. With these coordinates, I am trying to figure out the center of the picture, but figuring out the correct numbers is proving difficult. Here is what I know so far: 1) Unlike in the old ways, it is no longer 1000, 1000 by -1000, -1000 2) The coordinates that are returned are in float

问题 I have a problem with vertically align 3 spans inside a div. It's easy to achieve, but vertical align doesn't work when i use float. I want that lightblue bar to be vertically centered. Code: .container { } .text-1 { float: left; padding-right: 10px; } .bar { background-color: lightblue; border-radius: 5px; float: left; height: 5px; width: 150px; } .text-2 { padding-left: 10px; } <div class="container"> <span class="text-1">Text 1</span> <span class="bar"> </span> <span class="text-2">Text 2<

问题 I have a loading popup that I need to display on the top of the page, even if the user scroll down. What I tried so far is to set the popup position as follows setPopupPosition(Window.getClientWidth()/2 , 0); The popup shows up on the absolut top. 回答1: The situation can be resolved easily if you view it from a different angle: Not the popup position should adjust to the page - instead, the page should scroll behind the centering popup, e.g.: final ScrollPanel scrollPanel = new ScrollPanel();

问题 I need to list the ranking (or position, as you might prefer) or each document after a query in solr. the thing i wanna see is something like this: <doc> <int name="field1">1</int> <str name="someotherfield">blabla</str> <int name="position">1</int> </doc> <doc> <int name="field1">2</int> <str name="someotherfield">blabla</str> <int name="position">2</int> </doc> <doc> <int name="field1">3</int> <str name="someotherfield">blabla</str> <int name="position">3</int> </doc> is this possible? or i

问题 When I re-size windows of any browser by zooming-in or zooming-out. Popover is not updating position and showing at wrong place. How do I change the placement/position of Bootstrap Popover upon re-sizing / zooming the browser's window. 回答1: It seems to work fine in Bootstrap 2.2.1 (unless I am understanding your question wrong). Try the live demo at http://twitter.github.com/bootstrap/javascript.html#modals to see if this is what you are looking for. I use onresize event for the window to set

问题 I am using Jquery terminal and it seems pretty cool. I've been looking around for several hours now, and I can't find a way to get the console to remain stationary when text is inputted. Instead, the console increases in size for every line of input that I enter. Does anyone know how to keep a constant size for the terminal, is it a setting I missed or something? I want something like this. 回答1: Add a height option: JS $('#terminal').terminal(function (command, term) { if (command == 'test')

问题 so I'm trying to know when an event happened before another event in matlab; by event I mean number. For example, I have a vector, let's say: x = [0.3 0.3 0.1 0.2 0.5 0.1 0.3 0.1 0.5 0.1 0.4 0.5] and I want to know in which position is the 0.1 that happened before a 0.5. I tried with find(x,0.5,'last') but that doesn't help much since I want to then find the 0.1. I thought about maybe creatig another vector that ended at the 0.5 and then search for the last 0.1 but that would just be sort of
