scroll

问题 I have a simple screen example trying to implement the ScrollToAsync function. I can't get the function to scroll at all. My XAML: <?xml version="1.0" encoding="utf-8" ?> <ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="MyApp.ItemList"> <ContentPage.Content> <ScrollView x:Name="myScroll"> <StackLayout> <Label Text="Welcome to Xamarin.Forms!" /> <Label Text="Welcome to Xamarin.Forms!" /> <Label Text="Welcome to Xamarin

问题 I have a slide out mobile menu that has overflow set to auto so it will allow the user to scroll if the menu is too long. I want to the user to be able to reach the end of the menu without the page scrolling on them. I've tried each of these: $(window).scroll(function(e){ e.preventDefault(); }); $(window).scroll(function(e){ e.preventDefault(); e.stopPropagation(); }); $(window).scroll(function(e){ return false }); $('body').scroll(function(e){ e.preventDefault(); }); $('body').scroll

问题 I am using Openlayers with Angular , and have embedded a simple map on the screen. I have disabled interactions like so: this.map = new Map({ target: 'map', interactions: [], layers: [this.layer], view: this.view }); This prevents the map from panning when it is touched & dragged, which is what I need. However, I would like to be able to vertically scroll the browser page down by pressing & dragging the map so the user is able to see content below the map. At the moment, it is only possible

问题 I have a .Net Panel control that contains a single child control that is a WebBrowser. I won't go into the reasons for me doing that, but it is related to printing out the control. The panel control has its AutoScroll property set to "true" and I am sizing the WebBrowser to fit its own content (by using the .Document.Body.ScrollRectangle.Size property of the WebBrowser when the NavigateComplete2 event fires). In this way, the scrollbar on the panel appears and you can scroll the panel up and

问题 so I have multiple divs of the same class below each other. I now want to trigger a "loading comments"-function every time a visitor scrolls to a new div. However, I have no idea how to track jQuery scroll over a div. The comments for each div should only be loaded once, my idea would be to save the current position in a variable and only load comments when the new scroll position is greater than the old one. Can you please help me out? EDIT: I created a image that shows what I need to do.

问题 I know that the problem have been treated in other post but after reading several articles and tutorial i don't understand... I have the follogin rox.xml for each listview item <?xml version="1.0" encoding="utf-8"?> <RelativeLayout android:id="@+id/RelativeLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#FFFFFF" xmlns:android="http://schemas.android.com/apk/res/android"> <ImageView android:layout_height="50sp" android:layout_width="50sp"

问题 I have several iFrames that load an external webpage, although only 1 appears at a time, hence all have the id="iFrame" I want to add to buttons (not the scrollbar) so the user can scroll down or up by pressing them, and I am trying to do this using javascript but so far I've been unsuccessful, I've read some posts here and tried those answers but so far no luck. I have also tried: var newFrame = document.getElementsByTagName('iframe'); if(typeof newFrame !== 'undefined'){ newFrame

问题 So I have a page that is split into 2 columns. The left column there are expandable forms that are quite long to ask the user optional product preferences. On the right side of the page there is a much shorter, 'contact details' form. The contact details form is mandatory. The behaviour idea is that as the user scrolls down to complete the left column optional forms, the page will only scroll the left column - the contact details forms displayed in the right column stays in place to avoid a

问题 I have a scrollable container whose scrollLeft changes from the currentValue to currentValue + 10 on each requestAnimationFrame tick (read interval). However, this transition produces a staggered effect leading to the scrolling happening in an instant instead of animating from currentValue to currentValue + 10 . Is there a way to define an easing function in this case just like we do for transitions? Also, I need to do this without jQuery. 回答1: Sure you can, but you need to know the
