js比较时间段是否重叠

//获取全部时间判断是否重叠
var startTimeArr = [];
var endTimeArr = [];
var timeS = ‘‘;
var timeE = ‘‘;
for(var i = 0;i<tableEdit.length;i++){
    timeS = tableEdit[i].beginTime;
    startTimeArr.push(timeS);
}
for(var i = 0;i<tableEdit.length;i++){
    timeE = tableEdit[i].endTime;
    endTimeArr.push(timeE);
}
startTimeArr.push(editTimeS);
endTimeArr.push(editTimeE);
var begin = startTimeArr.sort();
var over = endTimeArr.sort();
for(var k = 1;k<begin.length;k++){
    if(begin[k]<over[k-1]){
        layerEditFlage = true
    }
}

if(layerEditFlage){
    layer.msg(‘时间段有重叠,请检查!!‘);
    layerEditFlage = false;
}
