larchanka / uniqid.js
Last active October 27, 2019 08:51
JavaScript function that copies functionality of PHP's 'uniqid'.
(function () {
this.uniqid = function (pr, en) {
var pr = pr || '', en = en || false, result;
this.seed = function (s, w) {
s = parseInt(s, 10).toString(16);
return w < s.length ? s.slice(s.length - w) : (w > s.length) ? new Array(1 + (w - s.length)).join('0') + s : s;
};
result = pr + this.seed(parseInt(new Date().getTime() / 1000, 10), 8) + this.seed(Math.floor(Math.random() * 0x75bcd15) + 1, 5);

Function `browserTransform` detects css-transforms' support in browser and returns css-property, else it returns false.
(function () {
this.browserTransform = function () {
if ('OTransform' in document.body.style)
return '-o-transform';
else if ('webkitTransform' in document.body.style)
return '-webkit-transform';
else if ('mozTransform' in document.body.style)

larchanka / findEntity.js
Last active August 29, 2015 13:56
Function allows to find entity in array/object by key and value. @param `keyObj` – key and value, i.e. {id:10}.
Object.prototype.findEntity = function(keyObj) {
var arr = this, p, key, val, ret;
for (p in keyObj) {
if (keyObj.hasOwnProperty(p)) {
key = p;
val = keyObj[p];
}
}
for (p in arr) {
if (p == key) {

JavaScript: Java String.hashCode() implementation. Source: http://goo.gl/Hyt1ku

char = this.charCodeAt(i);
hash = ((hash << 5) - hash) + char;
