异步控制器和Ajax请求(Asynchronous controller AND Ajax request)

我有一个异步控制器,我知道该操作将异步工作(没有其他操作等待)并在完成任务后返回。

所以我的问题是如何对动作发出异步Ajax请求。 我认为结果都是一样的。


I have an asynchronous controller, I know the action will work asynchronously (no other action wait for that) and returns after completion of the task.

So my question is how it is deferent from making an asynchronous Ajax request to an action. I think both are same in result.

最满意答案

您可以尝试以下表达式:

x <- "weg|laan" # or paste(c("weg", "laan"), collapse="|")
df$test <- ifelse(grepl(x, df_weg), 1, 0)

|regex意味着“或”

作为一种更直接的方式,感谢@DavidArenburg,因为您需要0/1输出,您只需将grepl的逻辑结果转换为整数:

as.integer(grepl("weg|laan", df_weg))

或者,如果你想做代码转换(但不太好的实践):

+grepl("weg|laan", df_weg)

You can try the following expression:

x <- "weg|laan" # or paste(c("weg", "laan"), collapse="|")
df$test <- ifelse(grepl(x, df_weg), 1, 0)

| in a regex means "or"

As a more direct way, thanks to @DavidArenburg, as you need a 0/1 output, you can just convert the logical result of grepl to integer:

as.integer(grepl("weg|laan", df_weg))

or, if you want to do codegolfing (but less good pratice):

+grepl("weg|laan", df_weg)
