I'd like to compare two strings (a before and after) and detect exactly where and what changed between them. For any change, I want to know: Starting position of the change (inclusive, starting at 0) Ending position of the change (inclusive, starting at 0) relative to the previous text The "change" Assume that strings will change in only one place at a time (for example, n
我想比较两个字符串(之前和之后)并检测它们之间的确切位置和变化。 对于任何改变,我想知道: 更改的起始位置(包括从0开始) 变更结束位置(包括从0开始)相对于以前的文本 改变” 假设字符串一次只能在一个地方变化(例如,从不“ B il l ” - >“ K il n ”)。 另外,我需要开始和结束位置来反映变化的类型: 如果删除,开始和结束位置应分别为已删除文本的开始和结束位置 如果替换,开始和结束位置应分别为
This is my Mongoose model: var sessionSchema = new Schema({ _id: { type: String, required: true, index: { unique: true } }, user: { type: Schema.Types.ObjectId }, expire: { type: Date, index: { expireAfterSeconds: 21600 } } }) module.exports = mongoose.model('Session', sessionSchema) I need to be able to set a date object into expire (usually it's something like Date.now plus a
这是我的Mongoose模型: var sessionSchema = new Schema({ _id: { type: String, required: true, index: { unique: true } }, user: { type: Schema.Types.ObjectId }, expire: { type: Date, index: { expireAfterSeconds: 21600 } } }) module.exports = mongoose.model('Session', sessionSchema) 我需要能够将日期对象设置为过期(通常它类似于Date.now加上几分钟),并在过期6小时后将对象从集合中移除。
In Javascript, suppose I want to perform some cleanup when an exception happens, but let the exception continue to propagate up the stack, eg: try { enterAwesomeMode(); doRiskyStuff(); // might throw an exception } catch (e) { leaveAwesomeMode(); throw e; } doMoreStuff(); leaveAwesomeMode(); The problem with this code is that catching and rethrowing the exception causes the stack trace
在Javascript中,假设我想在异常发生时执行一些清理,但让异常继续向上传播堆栈,例如: try { enterAwesomeMode(); doRiskyStuff(); // might throw an exception } catch (e) { leaveAwesomeMode(); throw e; } doMoreStuff(); leaveAwesomeMode(); 该代码的问题在于捕获并重新抛出异常会导致直至该点的堆栈跟踪信息丢失,因此如果随后再次捕获到异常(在堆栈上更高),则堆栈跟踪只会下降至-扔。 这很糟糕,因为这
In Firefox I can get the stack trace of an exception by using exception.stack . Is there a way to get that in other browsers, too? Edit: I actually want to save the stack trace automatically (if possible) and not debug it at the time (ie I know how to get the stack trace in a debugger). Place this line where you want to print the stack trace: console.log(new Error().stack); Note: tested b
在Firefox中,我可以使用exception.stack获取异常的堆栈跟踪。 有没有办法在其他浏览器中获取? 编辑:我实际上想自动保存堆栈跟踪(如果可能的话),而不是在那个时候调试它(即我知道如何在调试器中获取堆栈跟踪)。 将此行放在要打印堆栈跟踪的位置: console.log(new Error().stack); 注意:由我在Chrome 24和Firefox 18上进行测试 也值得看看这个工具。 Webkit现在具有提供堆栈跟踪的功能: Web Inspector:
I have an Express app that uses node-slack-sdk to make posts to Slack when certain endpoints are hit. I am trying to write integration tests for a route that, among many other things, calls a method from that library. I would like to prevent all default behavior of certain methods from the Slack library, and simply assert that the methods were called with certain arguments. I have attempted
我有一个Express应用程序,它使用node-slack-sdk在某些终端点击时将帖子发布到Slack。 我正在尝试为一条路线编写集成测试,其中包括从该库中调用一个方法。 我想阻止Slack库中某些方法的所有默认行为,并简单地声明这些方法是用某些参数调用的。 我试图简化这个问题。 我如何将WebClient实例的方法(实际上嵌套在chat )进行存根,阻止原始功能,并对其调用的参数进行断言? 我尝试了很多没有奏效的东西,所以我正在编辑
On Fullcalendar 2, when I navigate between weeks, I'd like to maintain the same time ranges in the vertical scroll. For example, in the below images, I am initially looking at times from 12am-3pm. But when I press the next arrow to go to the next week, it resets at 8am. I know that I can change the default starting time with scrollTime: "08:00:00", but how do I make it so that the verti
在Fullcalendar 2上,当我在几周之间导航时,我想在垂直滚动中保持相同的时间范围。 例如,在下面的图片中,我最初的时间是从上午12点到下午3点。 但是当我按下下一个箭头去下一周时,它会在上午8点重置。 我知道我可以通过改变默认的开始时间 scrollTime: "08:00:00", 但我该如何做到这一点,以便垂直时间范围“固定”到我所处的位置? 不幸的是,这不是内置功能。 有一种解决方法,但是当你进入前一周/下一周时,你总会
I know 3D rotation is well documented on SO and many other sites, but despite reading countless explanations I still haven't figured out where I'm going wrong. My background is in art and design, not math and programming, and I'm never really certain if my angle of attack (no pun intended) is the right one. Rather than paste a patchwork of my dismal code, I'm including an image
我知道SO和许多其他网站都有很好的3D旋转记录,但尽管阅读了无数的解释,但我仍然没有弄清楚我错在哪里。 我的背景是艺术和设计,而不是数学和编程,而且我从来没有真正确定我的攻角(不是双关语)是否是正确的。 我并没有粘贴我糟糕的代码拼凑而成的东西,而是包含描述我的问题的图像。 我真正喜欢的是如何解决它的一步一步的分解。 伪代码很有用,但如果有人只会瞄准我的正确方向或指出常见的陷阱,我会了解更多信息。
Currently iam using google map to display a particular location on map_canvas. There iam also plotting some markers too. In my application there is an option to set zoom level of the map by the user. User can pinch zoom on map and return the current map zoom value, when clicking on a button the value will be saved. i attain it by using this.mapObj.getZoom(); What my requirement is to get
目前iam使用谷歌地图在map_canvas上显示特定位置。 有Iam也绘制一些标记。 在我的应用程序中,用户可以选择设置地图的缩放级别。 用户可以在地图上缩放缩放并返回当前的地图缩放值,单击按钮时该值将被保存。 我通过使用达到它 this.mapObj.getZoom(); 我的要求是在用户执行缩放后获取地图的缩放级别,以便我可以将其显示在div中,以便用户在每次缩放/缩放缩小后可以知道缩放级别。 任何人都有任何想法如何才能在缩
We are developing a GIS application on top of Google Map (using Google Map API v3), however the application requires the user to zoom in close since some of the map objects are small (down to about 1 meter), and will require graphic editing. What is the best way to extend the zoom-range in Google Map API, down to maybe zoom level 30? Can we implement a tile server that "takes over" w
我们正在Google Map(使用Google Map API v3)之上开发一个GIS应用程序,但是由于一些地图对象很小(小到大约1米),因此应用程序需要用户放大关闭,并且需要进行图形编辑。 在Google Map API中扩展缩放范围的最佳方法是什么?缩小到30级缩放? 我们可以实现一个瓦片服务器,当谷歌拼图服务器达到极限时“接管”? 或者让谷歌地图API只使用图形放大来获取超出其数据范围的缩放级别? 任何其他可能的方法? 使用Hybrit或卫星
How do I set the zoom level to show all the markers on Google Maps? In my Google Map there are different markers in different positions. I want to set google map zoom level based on the range of markers (that means in the view of google map, i want to see all markers) There you go: <!DOCTYPE html> <html> <head> <meta http-equiv="content-type" content="text/html; ch
如何设置缩放级别以显示Google地图上的所有标记? 在我的Google地图中,不同位置有不同的标记。 我想根据标记范围设置谷歌地图缩放级别(这意味着在Google地图视图中,我想查看所有标记) 你去那里: <!DOCTYPE html> <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"/> <title>Google Maps getBoundsZoomLevel Demo</title> <scri
