问题 I have a functionA which accepts a function as a parameter. I want to manipulate the arguments of that function in functionA and return this as functionC. I found that I can do this with .apply(), however the original context of functionB is lost and instead replaced by functionA. For example, var factory = { return { fnB: function() {} } }; fnA(fn) { return fnC(params) { var customparams = [params, {something: else}] return method.apply(null, customparams); } } var load = fnA(factory.fnB);

问题 I need to adjust my jqgrid height dynamically to fit in the browser window as screen resolution changes.I need to calculate the header and footer ,and form(optional)..Then grid should be fitted in the remaining space. 回答1: You could set the height of the .ui-jqgrid-bdiv element via css calculating the height based on the window.innerHeight property.

问题 I am attempting to write a C# wrapper for the Twilio Programmable Chat tool. The library provided is for JS clients. I thought that using a tool like ClearScript (V8) would allow me to wrap the js as needed. The example code on the site is const Chat = require('twilio-chat'); // Make a secure request to your backend to retrieve an access token. // Use an authentication mechanism to prevent token exposure to 3rd parties. const accessToken = '<your accessToken>'; Chat.Client.create(accessToken)

问题 Is it possible to place a table generated with the xtable (or alternatively the pander ) package and a generated plot side-by-side in R markdown knitting to pdf while the rest of the document is not in columns? The following simple example hopefully illustrates the idea: \begin{multicols}{2} ```{r} plot(cars) ``` ```{r, results='asis'} library('xtable') print(xtable(head(cars,5)), type = "latex") ``` \end{multicols} However, this does not produce the plot. I know that solutions exist using
