regex - Find all variants of word in R -


i have following words.

words <- c("hail(0.75)", "hail0.75", "hail0.88", "hail075", "hail1.00", "hail1.75", "hail100", "hail125", "hail1.75)", "hail150", "hail175", "hail200", "hail225", "hail275", "hail450", "hail088", "hail75", "hail80", "hail88")       [1] "hail(0.75)" "hail0.75"   "hail0.88"   "hail075"    "hail1.00"   "hail1.75"        [7] "hail100"    "hail125"    "hail1.75)"  "hail150"    "hail175"    "hail200"        [13] "hail225"    "hail275"    "hail450"    "hail088"    "hail75"     "hail80"         [19] "hail88"

as can see, hail(0.75) repeated various typos/formatting (i.e. hail075, hail0.75)

how can find occurences of hail(0.75) including variants described above?

i've tried

grep("hail[0,7,5]"), words, value = t) [1] "hail0.75" "hail0.88" "hail075" "hail088" "hail75"

to find instances of hail contain numbers 075.
however, includes hail088 unwanted , excludes hail(0.75) wanted.

another option remove not digit numbers , use index:

idx <- gsub("[^[:digit:]]","",words) words[idx=="075"] [1] "hail(0.75)" "hail0.75"   "hail075"

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
