添加数字字段排序支持

var Arrs=new Array(realLength);for(var i=0;i<realLength;i=i+1){var intArr=new Array(2);intArr[0]=$("#tDate tr:eq("+i+") td:eq("+index+")").html();intArr[1]=$("#tDate tr:eq("+i+") td:eq(0)").html();Arrs[i]=intArr;}var AfterArr=new Array(realLength);for(var i=0;i<realLength;i++){for(var j=i+1;j<realLength;j++){if(parseFloat(Arrs[i][0])>parseFloat(Arrs[j][0])){var temp=new Array(2);temp=Arrs[i];Arrs[i]=Arrs[j];Arrs[j]=temp;}}AfterArr[i]=allDate[Arrs[i][1]-1];}allDate=AfterArr;
