項目用到handsontable 插件
根據官網 API寫的handsontable初始化,
數據展現,
ajax請求,
參數封裝,
Controller參數接受node
全局容器ajax
1 var AllData = {}; 2 var updatelist = []; 3 var delidslist =[]; 4 var insertlist=[];
handsontable 的初始化express

刪除list封裝([ id1,id2,…])json
1 //刪除的優先級最高 2 function delExpressCount (ids){ 3 //傳入的ids.length不可能爲0 4 $.each(ids,function(index,id){ 5 if(id!=null){ 6 delidslist.push(id); 7 } 8 }); 9 AllData.delidslist=delidslist; 10 }
刪除的優先級別大於更新,若是一條數據被更新了又被刪除了,事實上不須要執行更新操做的api
1 //updatelist數據更新 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封裝進AllData 13 AllData.updatelist=updatelist; 14 } 15 }
更新list封裝([{expresscount1},…])app
1 //更新數據 2 function updateExpressCount(data){ 3 if(JSON.stringify(data) != "{}"){ 4 var flag = true; 5 //判斷記錄是否存在,更新數據 6 $.each(updatelist,function(index,node){ 7 if(node.id==data.id){ 8 //此記錄已經有了 9 flag = false; 10 //用新獲得的記錄替換原來的,不用新增 11 updatelist[index] = data; 12 } 13 }); 14 flag&&updatelist.push(data); 15 //封裝 16 AllData.updatelist=updatelist; 17 } 18 }
清空全局容器ide
clearContainer =function (){ AllData = {}; updatelist = []; delidslist =[]; insertlist=[]; }
1 //得到當前時間 2 function getNowFormatDate() { 3 var date = new Date(); 4 var seperator1 = "-"; 5 var seperator2 = ":"; 6 var month = date.getMonth() + 1; 7 var strDate = date.getDate(); 8 if (month >= 1 && month <= 9) { 9 month = "0" + month; 10 } 11 if (strDate >= 0 && strDate <= 9) { 12 strDate = "0" + strDate; 13 } 14 var currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate 15 + " " + date.getHours() + seperator2 + date.getMinutes() 16 + seperator2 + date.getSeconds(); 17 return currentdate; 18 }
加載用戶數據，並綁定到handsontablepost
1 function loadDataTable(){ 2 showWait(); 3 $.ajax({ 4 url:'fillList', 5 type:'post', 6 dataType:'json', 7 success:function(rdata){ 8 closeWait(); 9 var convertData = []; 10 if (rdata && typeof rdata === "object") { 11 //從新封裝數據,由於時間類型不符合要求 12 $.each(rdata,function(index,node){ 13 convertData.push({ 14 id:node.id, 15 myeven:node.myeven, 16 expresssum:node.expresssum, 17 ersystem:node.ersystem, 18 concursystem:node.concursystem, 19 apisystem :node.apisystem, 20 todaydate :common.timestampToDate(node.todaydate), 21 enddate:common.timestampToDate(node.enddate), 22 delayday:node.delayday 23 }); 24 }); 25 onIniHandsonTable(convertData); 26 } 27 else{ 28 $.alert({ 29 title: '消息提示', 30 type: 'red', 31 content: '加載數據失敗.', 32 }); 33 } 34 }, 35 error:function(e,j,t){ 36 closeWait(); 37 $.alert({ 38 title: '錯誤提示', 39 type: 'red', 40 content: '加載數據錯誤.', 41 }); 42 console.log('express count/fill error:'+j+','+t); 43 } 44 }); 45 }
