Limit Multiple MongoDB Array Size

由 为君一笑 提交于 2019-12-02 08:30:59
I have a document that lists post item ids for an author separated out by topic. This results in a document such as the following: { _id: "sdkafjsadkfjads3023", Author: "SomeGuy" RecentPosts: { "topic-1": { Count: 4, Posts: ["postitemid1","postitemid2","postitemid2","postitemid3"] } "topic-2": { Count: 3 Posts: ["postitem5","postitem6","postitem8"] } } } Most of the time I am doing atomic pushes to each of these post arrays in the same update. What I want to do is limit the arrays above to 10 items at all times. This way, anytime I do a pushall to the same topic/posts. Is what I'm asking even

Position:fixed to work on IE 6/7/8 and mozilla

由 醉酒当歌 提交于 2019-12-02 08:21:04
I want to make a div's position fixed on the bottom right of a page..( a chat box) ..how do i do that through a css file which will work on all IE6/7/8 and mozilla ....for now i have #chatBox{ position: fixed; bottom: 0%; right: 1%;} This doesn't work on IE..and my constraint is that I am just allowed to edit this CSS file ( so can't set the html to strict mode too). Workarounds I found on the web just talk about position w.r.t to the top of the page not bottom. thanks Mohan You can fix IE with CSS expressions. Serve the following to IE with conditional comments : /* smooths out the IE

position:fixed 造成页面抖动解决办法

由 旧城冷巷雨未停 提交于 2019-12-02 06:13:11
今天做项目遇到一个问题。鼠标滚动到指定长度后，理想状况是菜单吸附到顶部。但是实际上在一些页面上会造成抖动。定位之后发现。window.pageYoffset值会变成0 搜索一些资料后发现。因为fixed定位后，这个div 就已经脱离文档流了。window.pageYoffset指的是document元素距离视窗的距离。所以导致window.pageYoffset变成了0 解决办法： 假设我们把fixed定位的div为divA, 那么在divA下面再写一个占位的div B,它的高度和divA一致，visible设为隐藏。用于占位文档流。这样就不会造成样式混乱了。 来源： https://www.cnblogs.com/ada-blog/p/11733965.html

background-attachment : fixed; not working with background-position

I have made a codepen to explain my problem: When the user scroll, the blue images should follow the user scroll The blue images should be stuck on the opposite side of the aside parts (right for the left one | left for the right one) The pb is that background-attachment : fixed; isn't working this the css rule background-position: left 0px; Someone can help me by forking the codepen to show me a working implementation ? .wrapper { display: flex; } main { background-color: red; height: 1000px; max-width: 992px; width: 100%; } aside { min-width: 150px; background-color: green; } .left {

Fixed statement with jagged array

由 爷，独闯天下 提交于 2019-12-01 21:41:48
I have jagged array which I need to pass to external method. [DllImport(...)] private static extern int NativeMethod(IntPtr[] ptrArray); ... fixed (ulong* ptr = array[0]) { for (int i = 0; i < array.Length; i++) { fixed (ulong* p = &array[i][0]) { ptrArray[i] = new IntPtr(p); } } NativeMethod(ptrArray); } The problem is that ptr is unused and is removed due compilation. Than fixed statement according to it is removed too. So array be moved by GC in that way that ptrArray elements become invalid. What is the best way for passing jagged arrays as single-dimensional arrays of pointers to native

Content appearing behind fixed header

由 本秂侑毒 提交于 2019-12-01 17:53:31
I fixed the header section of a website, but the first div of the page appears behind the header; instead of starting from the end of the header. When you apply position: fixed or position: absolute the element is being removed from the document flow, so the elements that come after treat it as a non-existent. That's why your div jumps up. To fix that apply a margin-top that equals to your header height - http://jsfiddle.net/2xjES/ 来源： https://stackoverflow.com/questions/11126482/content-appearing-behind-fixed-header

disabled样式覆盖问题 IOS 移动端 input设置了 readonly 后仍然能被聚焦，后更改为 disabled . 延伸了一个新问题,禁用状态下字体颜色设置无效 12345678910111213141516 input[disabled],input:disabled,input[disabled="disabled"] { color: #000 !important; background: #fff !important;}// 样式设置没有起作用// 正确样式设置 input[disabled], textarea[disabled],select[disabled='disabled']{ -webkit-text-fill-color: rgba(0, 0, 0, 1); // 用于改变字体color opacity: 1; // 浏览器默认为0.3，所以得改为1 color: rgba(0, 0, 0, 1); background: white;} 300ms点击延迟 300ms点击延迟，用FastClick.js 扩展：FastClick.js实现原理，在document上绑定touchstart,touchstart,记录当前信息，阻止默认行为，创建一个自定义鼠标事件对象(type: click)，并触发该事事件，执行click的回调函数。
