JavaScript Underscore _.uniqueId Examples

Example #1

File: test-game.js Project: ykhrustalev/kozel-game

function createUser() {
  return {
    uid       : "mock" + _.uniqueId(),
    first_name: "first_name_" + _.uniqueId(),
    last_name : "last_name_" + _.uniqueId()
  };
}

Example #2

File: backbone.js Project: kindy/loader

 Backbone.View = function(options) {
   this.cid = _.uniqueId('view');
   this._configure(options || {});
   this._ensureElement();
   this.delegateEvents();
   this.initialize(options);
 };

Example #3

File: socket.server.js Project: zeropaper/kern

 ioChannel.on('connection', function(socket) {
   
   storage[channelId] = storage[channelId] || {};
   storage[channelId][socket.id] = {
     'name': _.uniqueId('User ')
   };
   
   if (!_.isUndefined(channel.on) && !_.isUndefined(channel.on.channel)) _.each(channel.on.server || (channel.on.server = {}), function(callback, eventName) {
     socket.on(eventName, callback);
     S.channels[eventName] = {};
   });
   
   
   K.sockets[channelId] = socket;
 });

Example #4

File: backbone.js Project: kindy/loader

 Backbone.Model = function(attributes, options) {
   var defaults;
   attributes || (attributes = {});
   if (defaults = this.defaults) {
     if (_.isFunction(defaults)) defaults = defaults();
     attributes = _.extend({}, defaults, attributes);
   }
   this.attributes = {};
   this._escapedAttributes = {};
   this.cid = _.uniqueId('c');
   this.set(attributes, {silent : true});
   this._changed = false;
   this._previousAttributes = _.clone(this.attributes);
   if (options && options.collection) this.collection = options.collection;
   this.initialize(attributes, options);
 };

Example #5

File: util.js Project: tsq-old/js-utilities-note

/**
 * Created by tsq on 14-8-14.
 */
var _ = require("underscore")._;

//noConflict: 把_变量的控制权预留给它原有的所有，返回一个引用给underscore对象
// random _.random(min, max)
// 返回一个介于 min 和 max 之间(包含)的整数. 如果直传一个参数, 将会返回一个介于 0 和参数之间的整数
console.log(_.random(0, 100));

//mixin_.mixin(object) 
//允许您继承 Underscore 并加入您自己的功能函数. 传参 {名称: 函数} 来定义您的函数, 加入到 Underscore 对象中, 就像面向对象的封装.
_.mixin({
    capitalize: function(string, age){
        return string + age
    }
});
console.log(_('faf', 8).capitalize());

//unqueId 产生一个全局唯一id，以参数作为前缀
console.log(_.uniqueId('contact_'));
console.log(_.uniqueId('contact_'));
console.log(_.uniqueId('contact_'));
console.log(_.uniqueId('contact_'));

//escape,unescape:转义HTML字符串，反转到HTML字符串

console.log(_.escape('Curly, Larry & Moe'));
//=> Curly, Larry & Moe
console.log(_.unescape('Curly, Larry & Moe'));
//=> Curly, Larry & Moe
