Created December 19, 2018 05:57 — forked from barbietunnie/nginxproxy.md
How to proxy web apps using nginx?

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

Select2 populate option dynamically
var fromTitle = 'Paris';
var toTitle = 'paris_fr';
// Note: if id is same and title is updated then it won't change, so set a new id if you are updating a label and then set it back
var fromId = 'New York';
var toId = 'new-york-city_ny_us';
var newFromOption = new Option(fromTitle, fromId, false, false);
$('.fromLocation').eq(0).append(newFromOption); // add the option because of AJAX it would not exist
$('.fromLocation').eq(0).val(fromId); // Select the option with the value

This javascript function can be used to only allow typing of alphabets, & _ - and whitespace, it will remove all other characters, it uses a regex for this, you can modify to allow other characters, for example to allow numbers as well just add 0-9 to the regex after A-Z.
(function(){
// Allow only alphabets & _ - whitespaces, strip out all others.
function clean(str) {
return str.replace(/[^a-z-A-Z\&\_\- ]/g, "").replace(/ +/, " ")
}
$('body').on('keyup', '#ask_message_textarea, #ask_message_title', function(event) {
this.value = clean(this.value);

PHP equivalent of number_format in javascript
function number_format (number, decimals, dec_point, thousands_sep) {
// Strip all characters but numerical ones.
number = (number + '').replace(/[^0-9+\-Ee.]/g, '');
var n = !isFinite(+number) ? 0 : +number,
prec = !isFinite(+decimals) ? 0 : Math.abs(decimals),
sep = (typeof thousands_sep === 'undefined') ? ',' : thousands_sep,
dec = (typeof dec_point === 'undefined') ? '.' : dec_point,
s = '',
toFixedFix = function (n, prec) {
var k = Math.pow(10, prec);
