js前台判断开始时间是否小于结束时间,结合了jquery需要的朋友可以参考下

// 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;

// 将传递的时间值转换为SQL识别的时间格式

///时间(正常的页面显示时间格式)

///

var strResult = "";

var strTemp = "";
