i'm attempting pass data in request body , request parameter angular $resource call. below click handler controller , service calls: controller.js: vm.setlimit = function(limit) { var data = { activity: 'point_limit', limit: limit }; playersservice.setplayerlimit({ playerid: playerid, data }); }; service.js: angular.module('gameapp') .factory('playersservice', ['$resource', function($resource) { var base = '/api/players/:playerid/'; return $resource(base, {}, { getplayerinfo: {method: 'get', url: base + 'playerinfo'}, setplayerlimit: {method: 'post', url: base + 'playerlimit'} }); }]); getplayerinfo works, setplayerlimit not because, reason, not being passed playerid . playersservice.setplayerlimit should take 4 parameters in order: (request parameters, request body, success callback, error callback) modify code as...

i implemented images rollover css using code: .content3{ background-image:url(../img/tablet2.jpg); background-repeat:no-repeat; border:5px solid #fa8072; border-radius:5px; width:220px; height:200px; margin:0 auto; } .content3:hover{ background-image:url(../img/servizibis.png); background-repeat:no-repeat; border:5px solid #fa8072; border-radius:5px; width:220px; height:200px; margin:0 auto; } this works fine on website desktop version doesn't work on responsive version on ipad , smartphone android. exist solution javascript or jquery code?

edit: new package text2vec excellent, , solves problem (and many others) well. text2vec on cran text2vec on github vignette illustrates ngram tokenization i have pretty large text dataset in r, i've imported character vector: #takes 15 seconds system.time({ set.seed(1) samplefun <- function(n, x, collapse){ paste(sample(x, n, replace=true), collapse=collapse) } words <- sapply(rpois(10000, 3) + 1, samplefun, letters, '') sents1 <- sapply(rpois(1000000, 5) + 1, samplefun, words, ' ') }) i can convert character data bag-of-words representation follows: library(stringi) library(matrix) tokens <- stri_split_fixed(sents1, ' ') token_vector <- unlist(tokens) bagofwords <- unique(token_vector) n.ids <- sapply(tokens, length) <- rep(seq_along(n.ids), n.ids) j <- match(token_vector, bagofwords) m <- sparsematrix(i=i, j=j, x=1l) colnames(m) <- bagofwords so r can vectorize 1,000,000 million short sentenc...

i have tried searching solution everywhere not find it. hence posting request here. we have website built on php code-ignition mvc framework, issue html rendering on various devices imo. section on bottom of rendered page disappears on iphone, renders fine on ipad , normal browser. have saved page html , able reproduce via chrome devices (from developer tools), switching on various devices. the designer helped create these templates not accessible anymore, not able further help. suspect css issue. website uses twitter-bootstrap. screenshots: normal browser & iphone redering comparison: (the div in question marked arrow) i have looked view source , div in question appears on both versions in html source: <div class="button-holders button-overlay" id="button_holder"> <div class="col-sm-3 col-xs-3 noway" id="noway" style="display: block;"> <a id="noway1" style="cursor:point...
