问题 I have found the library PDF creation With this library it is possible to create different styles of pdf documents. My question would be if there is a possibility to mark text (and maybe add a link to this marked text) of an existing pdf file with AngularJS? Or is there any workaround to do this? 回答1: The question is a bit too broad as is - not sure what you mean by "mark" - do you mean highlighted in some way or actually selected? Anyhow, firstly to get to the correct page -- you can use

问题 In Chrome 61 , support for modules in JavaScript was added. Right now I am running Chrome 63. I am trying to use import / export syntax in Chrome extension content script to use modules. In manifest.json : "content_scripts": [ { "js": [ "content.js" ], } ] In my-script.js (same directory as content.js ): 'use strict'; const injectFunction = () => window.alert('hello world'); export default injectFunction; In content.js : 'use strict'; import injectFunction from './my-script.js';

问题 I'm wondering what the most idiomatic way is to use URI to add a query string to a base URI in Elixir. I'm currently doing something like this: iex(1)> base = "http://example.com/endpoint" "http://example.com/endpoint" iex(2)> query_string = URI.encode_query(foo: "bar") "foo=bar" iex(3)> uri_string = URI.parse(base) |> Map.put(:query, query_string) |> URI.to_string "http://example.com/endpoint?foo=bar" But was wondering if there is a cleaner way to set the query string. I know about URI.merge

问题 We have a ColdFusion 8 (Linux) application that uses an Oracle timestamp. We just converted to Oracle 11g from 10g and we're now using Oracle's thin client on the data sources. We're getting an error in the application where a timestamp column is selected. It seems as though an object of class oracle.sql.TIMESTAMP is being returned. I verified this by dumping the contents of the column. Sure enough, it gives me a break down of the object's methods and their return types. But, I can't seem to

问题 I'm facing a strange behavior with Cocoa NSView on Mac OS X. I've a custom NSView in a NSView container, this custom NSView tracks mouse movements, clicks, and has a tooltip. When I add a NSView above the described view, I can still see the tooltips even if the view with the tooltip is under, behind and not visible. I'm pretty sure that I misunderstood something in the event handling chain. Any help is really appreciated! 回答1: The core issue is that you are not supposed to have overlapping

问题 I'm trying to pass userId to hub on connection to signalR. This is how client sets up the connection: connection = new HubConnectionBuilder() .WithUrl("http://localhost:56587/hub", options => { options.Headers["UserId"] = loginTextBox.Text; }) .AddMessagePackProtocol() .Build(); How can I read this header in OnConnectedAsync() method in my hub? 回答1: To get Header Value as string: public override async Task OnConnectedAsync() { var httpCtx = Context.GetHttpContext(); var someHeaderValue =
