function compute() { var rows = $("#rep").datagrid("getRows")// 獲取當前的資料行
// 計算總和 var rtotal = 0, hctotal = 0 , wftotal = 0, zgwctotal = 0, mzgtotal = 0, is_heji = 0; for ( var i = 0; i < rows.length; i++) { rtotal += parseFloat(rows[i]['completeTask']); hctotal += parseFloat(rows[i]['totalTask']); wftotal += parseFloat(rows[i]['zongfindProblem']); zgwctotal += parseFloat(rows[i]['completeRectification']); mzgtotal += parseFloat(rows[i]['noCompleteRectification']);
//率：對存在NaN的值轉換（根據實際情況選擇） var a = (rtotal / hctotal * 100).toFixed(2); var b = (wftotal / hctotal * 100).toFixed(2); var c = (zgwctotal / wftotal * 100).toFixed(2); if (a == "NaN") { a = 0.00; } if (b == "NaN") { b = 0.00; } if (c == "NaN") { c = 0.00; } //排序或者在查詢下一頁的資料也會啟動到compute

()函式，所以當產生了合計值行的時候就不在重新新增一行合計，只是對資料進行重新的計算 if (rows[i]['areaname'] == "<b> 合計：</b>") { is_heji = 1; }} if (is_heji == 0) { // 新增一行顯示統計資訊 $("#rep").datagrid('appendRow', { areaname: '<b> 合計：</b>', completeTask: rtotal, totalTask: hctotal, findProblemRate: b, completeRectificationRate: c, zongfindProblem: wftotal, completeRectification: zgwctotal, noCompleteRectification: mzgtotal, completeTaskRate: a }); } }
