js前台判断开始时间是否小于结束时间

代码如下:

// 判断开始时间是否小于结束时间
if ($("#txtbegintime").length > 0 && $("#txtendtime").length > 0) {
if (date.parse(timeformattosql($("#txtbegintime").val()).replace("-", "/")) > date.parse(timeformattosql($("#txtendtime").val()).replace("-", "/"))) {
alert("开始时间不能大于结束时间!");
// $("#txtbeginsearchtimebybe").focus();
return;
///<summary>/// 将传递的时间值转换为sql识别的时间格式
///<param name="strtime">时间(正常的页面显示时间格式)</param>
///</summary>
function timeformattosql(strtime) {
var strresult = "";
var strtemp = "";
for (var i = 0; i < strtime.length; i++) {
strtemp = strtime.substr(i, 1);
if (strtemp == "年" || strtemp == "月")
strresult += "-";
else
if (strtemp == "日" || strtemp == "秒") {
if (strtemp == "日")
strresult += "|";
else
strresult += "";
}
else
if (strtemp == "时" || strtemp == "分")
strresult += ":";
else
strresult += strtemp;
}
var strargdatetime = strresult.split('|'); //此时的时间格式可能为2010-11-11 11: 或2010-11-11 11等格式
if (strargdatetime.length == 1) {
//日期部分进行处理
var strargdate = strargdatetime[0].split('-'); //此时对时间部分进行处理,可能为11: 11 或11:00等格式
if (strargdate.length == 2) {
if (strargdate[1].length < 1)
strresult = strargdate[0];
else
strresult = strargdatetime[0] + "-01";
} else
if (strargdate.length == 3) {
if (strargdate[2].length < 1)
strresult = strargdate[0] + "-" + strargdate[1] + "-01";
}
}
else
if (strargdatetime.length == 2) {
//时间部分进行处理
var strargtime = strargdatetime[1].split(':'); //此时对时间部分进行处理,可能为11: 11 或11:00等格式
if (strargtime.length == 1) {
strresult = strargdatetime[0] + " " + strargdatetime[1] + ":00:00"
} else
if (strargtime.length == 2) {
if (strargtime[1].length < 1)
strresult = strargdatetime[0] + " " + strargdatetime[1] + "00"
else
strresult = strargdatetime[0] + " " + strargdatetime[1] + ":00"
} else
if (strargtime.length == 3) {
if (strargtime[2].length < 1)
strresult = strargdatetime[0] + " " + strargdatetime[1] + "00"
}
}
return strresult;
}
