一.自定义座位号(即重新加载数据源)
例子1.自定义数据
[html] view
plain copy
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
[html] view
plain copy
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
return column;
},
getData:function(dataList){
console.log(dataList)
return dataList;
},
data:data1
},
3.源码修改 大概400行左右,修改lable
[html] view
plain copy
seats[id] = new seat({
id : id,
label : naming.data[row][column] ,
// label : overrideLabel ? overrideLabel : naming.getLabel(character, naming.rows[row], naming.columns[column]),
row : row,
column : column,
character : character
});
4.源码修改,25行左右 加入data参数
[html] view
plain copy
settings = {
animate : false, //requires jQuery UI
naming : {
top : true,
left : true,
getId : function(character, row, column) {
return row + '_' + column;
},
getLabel : function (character, row, column) {
return column;
},
data:[]
},
二.重新刷新数据
修改源码 在开始的位置[html] view
plain copy
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.items;
ary.splice(0,ary.length);
this.empty();
}
