jquery-seat-charts 使用-自定义座位号 及 重新加载数据
[摘要：一.自界说坐位号(即从新减载数据源)
1.自界说数据
var data1 = [['aa1','aa2','aa3','aa4','aa5','aa6'],['bb1&#]
一.自定义座位号(即重新加载数据源)
1.自定义数据
var data1 = [['aa1','aa2','aa3','aa4','aa5','aa6'],['bb1','bb2','bb3','bb4','bb5','bb6'],['cc1','cc2','cc3','cc4','cc5','cc6']];
2.html传输数据
naming: {//设置行列等信息
top: false, //不显示顶部横坐标（行）
// rows: ['3', '2', '1'],
// columns: ['A', 'B', 'C', 'G', 'D', 'F'],
getLabel: function(character, row, column) { //返回房间信息
getData:function(dataList){
console.log(dataList)
return dataL
data:data1
3.源码修改 大概400行左右,修改lable
seats[id] = new seat({
: naming.data[row][column] ,
: overrideLabel ? overrideLabel : naming.getLabel(character, naming.rows[row], naming.columns[column]),
character : character
4.源码修改,25行左右 加入data参数
settings = {
animate : false, //requires jQuery UI
: function(character, row, column) {
return row + '_' +
getLabel : function (character, row, column) {
二.重新刷新数据&
修改源码 在开始的位置
if (this.data('seatCharts')) {
// console.log(this.data('seatCharts'))
// return this.data('seatCharts');
// console.log(setup)
// console.log(setup.legend.items)
// console.log(this.data('seatCharts'))
var ary = setup.legend.
ary.splice(0,ary.length);
this.empty();

Hadoop是一个由Apache基金会所开发的分布式系统基础架构。
用户可以在不了解分布式底层细节的情况下，开发分布式程序。充分利用集群的威力进行高速运算和存储。
Hadoop实现了一个分布式文件系统（Hadoop Distributed File System），简称HDFS。HDFS有高容错性的特点，并且设计用来部署在低廉的（low-cost）硬件上；而且它提供高吞吐量（high throughput）来访问应用程序的数据，适合那些有着超大数据集（large data set）的应用程序。HDFS放宽了（relax）POSIX的要求，可以以流的形式访问（streaming access）文件系统中的数据。
Hadoop的框架最核心的设计就是：HDFS和MapReduce。HDFS为海量的数据提供了存储，则MapReduce为海量的数据提供了计算。
产品设计是互联网产品经理的核心能力，一个好的产品经理一定在产品设计方面有扎实的功底，本专题将从互联网产品设计的几个方面谈谈产品设计
随着国内互联网的发展，产品经理岗位需求大幅增加，在国内，从事产品工作的大部分岗位为产品经理，其实现实中，很多从事产品工作的岗位是不能称为产品经理，主要原因是对产品经理的职责不明确，那产品经理的职责有哪些，本专题将详细介绍产品经理的主要职责
Swift是Apple在WWDC2014所发布的一门编程语言，用来撰写OS X和iOS应用程序[1]。在设计Swift时．就有意和Objective-C共存，Objective-C是Apple操作系统在导入Swift前使用的编程语言
Swift是供iOS和OS X应用编程的新编程语言，基于C和Objective-C，而却没有C的一些兼容约束。Swift采用了安全的编程模式和添加现代的功能来使得编程更加简单、灵活和有趣。界面则基于广受人民群众爱戴的Cocoa和Cocoa Touch框架，展示了软件开发的新方向。
