javascript验证日期的函数 

//判断日期是否合法
function IsDate(oTextbox) {
    var regex = new RegExp("^(?:(?:([0-9]{4}(-|\/)(?:(?:0?[1,3-9]|1[0-2])(-|\/)(?:29|30)|((?:0?[13578]|1[02])(-|\/)31)))|([0-9]{4}(-|\/)(?:0?[1-9]|1[0-2])(-|\/)(?:0?[1-9]|1\\d|2[0-8]))|(((?:(\\d\\d(?:0[48]|[2468][048]|[13579][26]))|(?:0[48]00|[2468][048]00|[13579][26]00))(-|\/)0?2(-|\/)29))))$");
    var dateValue = oTextbox.value;
    if (!regex.test(dateValue)) {
        alert("日期有误！");
        dateValue = "";
        this.focus();
        return;
    }
}
