问题 So far I tried this but it returns unfiltered array: function filterRangeInPlace(array, min, max) { array = array.filter(item => (item >= min && item <= max)); console.log(array); } let arr = [5, 3, 8, 1]; filterRangeInPlace(arr, 1, 4); console.log(arr); 回答1: If it's actually important to do the filtering in-place without creating another array, you have to go sort-of old school and iterate through the array with two indexes, copying values along the way.

I just wanted to see if it was possible to only add the filter control by adding an icon on the header that adds the filter control on click

问题 I'm creating an API that takes a JSON like this: "hightlights":[ { "title":"Fun", "url":"fun/index.html", "queries": [ "music", "artists", "events", "internet" ] }, { "title":"Internet", "url":"internet/index.html", "queries": [ "javascript", "web", "internet", ] } ] I need to filter the JSON with a word given by user and return with another JSON with only object that contains the word in "queries".

问题 I have a dataframe in which one column contains numeric vectors. I want to filter rows based on a condition involving that column. This is a simplified example. df <- data.frame(id = LETTERS[1:3], name=c("Alice", "Bob", "Carol")) mylist=list(c(1,2,3), c(4,5), c(1,3,4)) df$numvecs <- mylist df # id name numvecs # 1 A Alice 1, 2, 3 # 2 B Bob 4, 5 # 3 C Carol 1, 3, 4 I can use something like mapply e.g. mapply(function(x,y) x=="B" & 4 %in% y, df$id, df$numvecs) which correctly returns TRUE for
