there seems lots of different answers on define cors headers when using owin. have seen these ... 1) add grantresourceownercredentials method context.owincontext.response.headers.add("access-control-allow-origin", new[] { allowedorigin }); 2) in configuration(iappbuilder app) method of startup.cs app.usecors(microsoft.owin.cors.corsoptions.allowall); 3) add web.config <system.webserver> <httpprotocol> <customheaders> <add name="access-control-allow-origin" value="*" /> <add name="access-control-allow-headers" value="content-type" /> <add name="access-control-allow-methods" value="get, post, put, delete, options" /> </customheaders> </httpprotocol> </system.webserver> when try multiple options error saying duplicate cors headers , therefore none of them allowed. is there single place can define cors po...

i have table called c33062 displays data rows in page. have twenty other mysql tables same structure , information, different data. instead of creating page each, i'd create hyperlinks each calls links table information. statement is: $query = "select id, year, price_avg_sold, price_sqft, pct_list_sold, adom, sold_nu, sold_chg, year_1, year_2, year_3, year_4, year_5, year_6, year_7, year_8, year_9, year_10 c33062"; so in essence, i'd make hyperlinks each table, c33063, c33064, c33065 etc when clicked, call particular table's data template page. what correct way hyperlink table? set table name variable in each link , variable value. example http://www.name.com?tabe=30063 table 30063 http://www.name.com?tabe=30064 table 30064 and table value $table = $_get['table']; then use variable in query code below: $query = "select id, year, price_avg_sold, price_sqft, pct_list_sold, ado...

i'm using navigatorios on react native app. want pass properties when navigating previous route. an example case: i'm in form page. after submitting data, want go previous route , based on submitted data how can pass state variables of current element previous route when using pop go back? any code sample appreciated. this classic example of trivially solved redux or other centralized state store. without that, behavior go "back" via navigatorios's pop method? takes no arguments, doubt that'll work @ all. the best use push , can define route contain form data in passprops : this.props.navigator.push({ title: navigatoriosexample.title, component: navigatoriosexamplepage, backbuttontitle: 'custom back', passprops: { formdata }, }); but really, use redux.

this code works perfect in chrome not in firefox, ie, edge. <input type="text" readonly onmouseenter="this.style.backgroundcolor='red'" onmouseleave="this.style.backgroundcolor='white'"> <input type="text" readonly onmouseenter="this.style.backgroundcolor='red'" onmouseleave="this.style.backgroundcolor='white'"> when press left mouse button on first input , move on second input - color changes correctly in chrome. not in firefox, ie, edge (second input not recorded onmouseenter event). with right , middle mouse button, works code perfect in broswers. do know how fix it? why not work? (i can use raw javascript in project)

i use self invoking functions include javascript code inside angular controller (i think saw somewhere best practice). controller looks this: (function() { // code })() i use gulp merge controllers 1 file. question this. mean of javascript code invoked , executed when application starts? if so, guess not approach. there solutions issue? comments? thanks no, not code gets executed. when define angular modules (function() { 'use strict'; angular .module('mymodule', []) .controller('mycontroller', ['$http', mycontrollerfunc]); function mycontrollerfunc ($http) { // ... } })(); what gets executed angular methods register module , controller. actual controller logic in callback function, , gets called when controller invoked (e.g. router). so, good, , wrapping code in anonymous functions idea keep, example mycontrollerfunc , out of global namespace.

how create function manually calculates pearson correlation in r. know there native function called cor , if want apply below equation in r each combination of columns in data frame, how it? i wish knew how, believe requires many for-loops, nested for-loops etc make happen , not strong @ programming yet. hope attempt such newbie me can learn. thanks example: set.seed(1) df = data.frame(v1 = rnorm(10), v2=rnorm(10), v3=rnorm(10), v4=rnorm(10)) # v1 v2 v3 v4 # v1 1.00 -0.38 -0.72 -0.24 # v2 -0.38 1.00 0.60 0.18 # v3 -0.72 0.60 1.00 0.08 # v4 -0.24 0.18 0.08 1.00 first write helper function calculate covariance: v <- function(x,y=x) mean(x*y) - mean(x)*mean(y) then use calculate correlation: my_corr <- function(x,y) v(x,y) / sqrt(v(x) * v(y)) here's quick check works correctly: > my_corr(df$v1, df$v2) [1] -0.3767034 > cor(df$v1, df$v2) [1] -0.3767034 note calculating correlation way numerically unstable...
