javascript - How $.contains() jquery function Works? -

i'm new jquery , don't know how $.contains() works in jquery.. tried code , know gives boolean value don't know how works exactly.. html: <div> <span>mm</span> </div> jquery code: $(document).ready(function() { if($.contains( $('div'), $('span') ) == true){ alert('yup'); }; }); can explain... the contains jquery method looks second argument child or descendant of first argument. while first arguments needs dom object such element or document type, have noticed unexpected behavior if second argument not dom object (like passing in jquery collection). you should stick using individual nodes (like element or document) method. if need check multiple items, use loop or iterator method (see jsfiddle example below). think of dom (document object model) tree. tree has stem , branches. root html element. there have branches head , body . each of branch further other elements. each branch ma...

R - extract number from string(special solution) -

i have string x <- "avd_1xx_2xx_3xx" need extract number x(string) , put them in new variables num1 <- 1xx num1 <- 2xx num1 <- 3xx however, can't predict number of digits each number instance, x "avd_1_2_3" or "avd_11_21_33" or likes could give me solutions? thanks we can use str_extract stringr . extract multiple matches use str_extract_all , returns list of length 1 (as have single element in 'x'). extract list element, can use [[ i.e. [[1]] . library(stringr) str_extract_all(x, "\\d+[a-z]*")[[1]] #[1] "1xx" "2xx" "3xx" a similar option using base r regmatches/gregexpr regmatches(x, gregexpr("\\d+[a-z]*", x))[[1]] #[1] "1xx" "2xx" "3xx" the pattern match 1 or more numbers ( \\d+ ) followed 0 or more lower case letters ( [a-z]* ). it better keep vector rather having multiple objects in global environment.

"specially encoded" data become useless , burden, serious restriction what "identifies" product may change business evolves if have seen...
