Handsontable 的数据保存(增删改查+导出excel)

项目用到handsontable 插件
根据官网 API写的handsontable初始化,
数据展示,
ajax请求,
参数封装,
Controller参数接受

全局容器

1     var AllData = {};
2     var updatelist = [];
3     var delidslist =[];
4     var insertlist=[];

handsontable 的初始化

  1 function onIniHandsonTable(data) {
  2         $('#hot').empty();
  3         var hotElement = document.querySelector('#hot');

删除list封装([ id1,id2,…])

 1 //删除的优先级最高
 2     function  delExpressCount (ids){
 3         //传入的ids.length不可能为0
 4             $.each(ids,function(index,id){
 5                 if(id!=null){
 6                     delidslist.push(id);

 9             AllData.delidslist=delidslist;
10     }

删除的优先级别大于更新,如果一条数据被更新了又被删除了,事实上不需要执行更新操作的

 1 //updatelist数据更新
 2     function screening(){
 3         if(updatelist.length!=0&&delidslist.lentgh!=0){
 4             for(var i=0;i<delidslist.length;i++){
 5                 for(var j=0;j<updatelist.length;j++){
 6                     if(updatelist[j].id == delidslist[i]){
 7                     //更新updatelist
 8                     updatelist.splice(j,1);
 9                     }
10                 }
11             }
12             //把updatelist封装进AllData
13             AllData.updatelist=updatelist;

更新list封装([{expresscount1},…])
