scroll

问题 I am trying to find a web element in Chrome with help of Selenium WebDriver. When the driver launches the URL, a list of projects is being displayed and the driver has to select a specific project from that list. As long as that project is on top of the list, it's ok and can find the project, however if project is at the very bottom of the list (as per list has been ordered alphabetically and say record 57 from list is tried to be selected), test keeps failing and driver can't find the web

问题 I have a RecyclerView and I've set android:animateLayoutChanges="true" in the item's CardView , because I'm changing its layout from a "visualization mode" to a "edit mode" when I click it. However, if I click the item then scroll immediately, items will overlap. Basically the item being animated doesn't respond to the scrolling. If I set android:animateLayoutChanges="false" however, they won't overlap but I will lose the animation. I've trying things like disabling scrolling while item

问题 Ok, here's my situation: I've been working on a chatroom type website for a side-project/hobby. The current layout uses html frames. The bottom frame is the "footer", or "message input" frame. The top frame is where the public messages are displayed. I use ajax to update the top frame every second. It works fine. My issue is this: I need to be able to keep the top frame scrolled all the way to the bottom -- UNLESS the user scrolls back up to view old messages, for example. I currently have a

问题 any ideas on how to scroll to bottom of a ckeditor editor using javascript / jQuery? I cant find anything. All my search shows is: document.getElementById("ID").contentWindow.scrollTo(0,3); Which gives me an error of contentWindow is undefined. The class of the ckeditor text part appears to be "cke_editable". Any help on scrolling to the bottom of the editor? 回答1: Access the editor and get the editable area via that instead of getting the DOM element directly. Like so: var editor = CKEDITOR

问题 I have an arbitrary amount of text that will be displayed in a confined space. How can I trim the output so that whatever is "beyond" the box is not displayed, or how can I force the box to create a vertical scroll bar? 回答1: The overflow property. You can set the value to hidden to hide the data and scroll to scroll the data. <div class="text">this is some text that would be very long...</div> //Hidden .text { overflow: hidden; width: 50px; height: 50px } //Scroll .text { overflow: scroll;

问题 I would like to detect when the scroll bar reaches the end of a data grid view, so I can run a function when this happens. I was exploring the Scroll event, but without success. Thanks. 回答1: This should get you close... place this in your Scroll event and it will tell you when the last row is visible: int totalHeight = 0; foreach (DataGridViewRow row in dataGridView1.Rows) totalHeight += row.Height; if (totalHeight - dataGridView1.Height < dataGridView1.VerticalScrollingOffset) { //Last row

问题 For testing purpose I have create project where I have two scrollview. First scrollview have images that I inserted manually and in second scrollview I have list of buttons (as menu).
