Coolite 计算单列总值的解决方案

使用GroupingSummaryColumn方式:
注意几点：
1，如果在自定义 CustomSummaryType="totalTimes", 要在
base.scmanager.Listeners.DocumentReady.Handler = "Ext.grid.GroupSummary.Calculations['totalTimes'] = totalTimes";
2，自定义SummarType后，只能使用<Renderer Fn="">
不可以使用Handler （它们有冲突）

<script type="text/javascript">
function getWorkTime(startTime, endTime, dTime) {
try {
var b1 = parseInt(startTime.split(":")[0], 10) * 60 + parseInt(startTime.split(":")[1], 10);
var b2 = parseInt(endTime.split(":")[0], 10) * 60 + parseInt(endTime.split(":")[1], 10);
var b3 = parseInt(dTime.split(":")[0], 10) * 60 + parseInt(dTime.split(":")[1], 10);
var s = Math.abs((b2 - b1 - b3) % 60);
if (s < 10) {
s = "0" + s;
}
var elapsed = Math.abs(parseInt((b2 - b1 - b3) / 60, 10)) + ":" + s;
return elapsed;

} catch (e) {
return '0:00';
}
}
var totalTimes = function(v, record, field) {
return Addtime(v, getWorkTime(record.data.StartTime, record.data.EndTime, record.data.BreakDuration));
//return Addtime(v,"0:00");
}
// function totalTimes(v, record) {

//// var dt = new Date();

// //return Addtime(dt, '0:15');
// }
function getTimevalue(time) {
if (time)
return parseInt(time.split(":")[0], 10) * 60 + parseInt(time.split(":")[1], 10);
else
return 0;
}
function Addtime(t1, t2) {
var tv = getTimevalue(t1) + getTimevalue(t2);
var s = Math.abs((tv) % 60);
if (s < 10) {
s = "0" + s;
}
return Math.abs(parseInt((tv) / 60, 10)) + ":" + s;
}
