i'm using jquery show characters remaining in text input , it's working fine when gets 0 characters remaining showing 1 though doesn't allow enter more. obvious , simple, it's stumping me today. here code i'm using: = form.text_field :name, { required: true, class: "#{'error' if @project.errors[:name].present?}", placeholder: '40 characters max', maxlength: 40, :onkeyup => "countcharname(this)" } span id="charname" class="margin-left-5" function countcharname(val) { var len = val.value.length; if (len >= 40) { val.value = val.value.substring(0, 40); } else { $('#charname').text(40 - len); } }; without testing it, assumption when reaches max length, input length 40. means if statement (len >= 40) true, else statement, updates $('#charname') remaining characters, doesn't run. try changing if statement (l...

given collection locations consisting of ~20,000,000 documents 3 properties: { _id, name, // string geo // coordinate pair, e.g. [-90.123456, 30.123456] } and index of name: 1 , geo index setup so: { "geo" : "2dsphere" }, { "v" : 1, "name" : "geo_2dsphere", "ns" : "db.locations", "min" : "-180.0", "max" : "180.0", "w" : 1.0, "2dsphereindexversion" : 2 } how can performantly query against collection both on geo_2dsphere index , on name index? when run $box query on geo index only, takes on 20 seconds return 50 results. when include search against name property goes further. if run $near query, things can perform quickly, queries seem (very randomly) go ~200ms many seconds. see example difference 1 additional character on name index increases time: 200ms: {name: /^mac/, geo: {$near...

i need make submitadapterauthentication() function work first getuserroles() function, current implementation of getuserroles() function being executed first submitadapterauthentication() . how can fix this? checkonline().then(function(onl) { userobj.isloginonline = onl; }).then(function() { submitadapterauthentication(user, pass); }).then(function() { getuserroles(); }); function submitadapterauthentication(user, pass) { var invocationdata = { parameters : [ user, pass ], adapter : "adapterauth", procedure : "submitlogin" }; ch.submitadapterauthentication(invocationdata, { onfailure : function(error) { wl.logger.log("error on fail: ", error); }, onsuccess : function() { wl.client.updateuserinfo({ onsuccess : function() { //return promise wl.client.updateuserinfo({ ...

question appropriate data structure: i have 5 variables have different values string based on whether in us/alaska , @ half/full resolution. so i'm building 5/2/2 (array or list or dict). i want access x = dstr(var,'ak','h') , e.g.. alaska/half-res, values osp/ul/lr/etc, variables? this static table, values won't change. there no obvious ordering demand 0,1,2 indices problem is, array doesn't string indices , dict wants 1 key only, not three. any ideas? you can use tuples index dict: >>> values = { ... ("ak", "h"): ("some", "sample", "data", "to", "return"), ... ("ak", "f"): ("more", "sample", "data", "for", "you"), ... # more data here ... } >>> a, b, c, d, e = values[("ak", "h")] >>> "some" or can use nest of dicts: ...
